Futuriom and Dell’Oro weigh in on SD-WAN and SASE market: single vendor solutions prevail

Enterprise networking and IT cybersecurity professionals are turning to managed SD-WAN (software-defined wide area networking) and SASE (secure access service edge) services to deal with the increasing challenges caused by network complexity, according to a new report from market research firm Futuriom.

SD-WAN and SASE have been evolving and maturing for several years now, but the market is far from mature. It is still growing and is highly fragmented, both in terms of the companies involved in providing services and technology to enterprise users and in how SD-WAN and SASE capabilities are deployed and consumed by enterprises.

What’s needed more than ever are software-based platforms for integrating the management of network and security functions at the same time. This approach was first initiated by SD-WAN, which separated the software control from the hardware for branch-office networking. SD-WAN evolved and grew by adapting security functionality (SASE), which could be integrated into the network platform.

The market has expanded to include SASE functionality, which provides cybersecurity functions such as secure web gateway (SWG), cloud access security broker (CASB), firewall-as-a-service (FWaaS), intrusion detection, zero-trust network access (ZTNA), and many others to protect enterprise access to public networks and SaaS apps.

Futuriom’s survey took place in March and April of 2023. The total audience of 196 respondents came from three countries: the U.S. (127 respondents), Germany (37), and India (32).

Report Highlights and Key Findings:

  • Survey respondents indicate strong demand for SD-WAN and SASE managed services. Our survey data and discussions with end users indicate that SD-WAN/SASE technology helps professionals with network and security challenges, including the growing complexity created by distributed applications, cloud connectivity, and sprawling security risks.
  • Managing network complexity is the largest challenge driving managed services demand. When asked about the largest challenges in managing WANs, 85% of respondents identified complexity, followed by expertise and knowledge (68%). Rounding out the responses were cost (60%) and time (47%). (Multiple responses were allowed.)
  • Hybrid work and the need for zero-trust network access (ZTNA) are key drivers of SD-WAN/SASE technology. In the survey, 98% of respondents said that hybrid work has increased demand for SASE and ZTNA. When we asked respondents if ZTNA is a crucial component of SASE and SD-WAN offerings, 92% said yes.
  • Hybrid (cloud/edge deployment) and single-pass architectures will be important components of SASE/SD-WAN services going forward. When respondents were asked if they wanted a hybrid solution that can accommodate networking and security both on premises and using cloud points of presence (PoPs), 98% said yes. In addition, 94% of respondents said they prefer a single-pass architecture.
  • There will continue to be a diversity of SD-WAN/SASE deployment models. The two most popular models for deployment are best-of-breed combination (34%) and single-vendor (23%), but survey results show a wide diversity of deployment models.

Companies covered in this report: Aryaka, Amazon, AT&T, British Telecom, Cato Networks, Check Point Software, Cisco, Colt, Comcast, Deutsche Telekom/T-Systems, Forcepoint, Fortinet, HPE (Aruba), Hughes, Juniper Networks, Lumen Technology, NTT, Orange, Palo Alto Networks, Tata Communications, Telefónica, Telstra, VMware, Verizon, Versa Networks, Vodafone, Windstream, Zscaler.


Separately, Dell’Oro Group reported that the portion of the SASE market, where vendors offer both SD-WAN and SSE (security service edge) solutions, grew an impressive 55% year-over-year (YoY) in 1Q 2023. By doing so, single-vendor SASE overtook the multi-vendor SASE portion of the market, consisting of vendors that can only offer the SD-WAN or SSE component. The overall SASE market revenue rose by over 30 percent for the fifth consecutive quarter in 1Q 2023 and, by doing so, was not far off the $2B mark.

“Even as enterprises have been more judicious in how they spend security budget, the robust growth of the SASE market is a testament to the strong commitment by enterprises and the value they bring to secure users’ access to cloud-based applications from anywhere,” said Mauricio Sanchez, Research Director at Dell’Oro Group. “The vendors that can offer both the SD-WAN and SSE components are setting themselves apart in an extremely competitive market,” added Sanchez.

Additional highlights from the 1Q 2023 SASE and SD-WAN Quarterly Report:

  • For the first time since Dell’Oro started tracking SASE in 1Q 2019, there was a revenue position change in the number one spot, with Zscaler overtook Cisco.
  • Palo Alto Networks overtook Broadcom (Symantec) for the number three overall SASE revenue position.
  • Check Point, HPE/Aruba, and Netskope became single-vendor SASE players.
  • Both SSE and SD-WAN revenue grew above 30 percent YoY.
  • Unified SASE solutions–defined as SASE solutions where SD-WAN and SSE have been tightly integrated into a single technology stack–eclipsed $200M for the third consecutive quarter, representing over 140% growth.
  • Overall SASE revenue growth on a regional basis varied from 27% in North America to 49% percent in the Caribbean and Latin America.
  • The Access Router market revenue surged forward by over 15% YoY on improved hardware supply.

IDC: Public Cloud software at 2/3 of all enterprise applications revenue in 2026; SaaS is essential!

IDC forecasts that worldwide revenue for enterprise applications will grow from $279.6 billion in 2022 to $385.2 billion in 2026 with a five-year compound annual growth rate (CAGR) of 8.0%. Nearly all this growth will come from investments in public cloud software, which is expected to represent nearly two thirds of all enterprise applications revenue in 2026.

While the process of migrating from on-premises applications to the cloud can take years, enterprise software vendors and their customers will continue the transition to the cloud as this is an essential part of business operations in the digital world. Companies that do not pursue this technology will sustain losses due to profound opportunity costs as their competitors adopt cloud technologies and the use of application programming interfaces (APIs), moving beyond the reach of technological holdouts with on-premises or homemade solutions.

“It’s no longer enough for businesses to sit back and rely on their technological debt of software and hardware assets to keep the company running. In the digital world, enterprise software needs to constantly innovate to keep up with demand for speed, scale, and a resilient business,” said Heather Hershey, research director, Worldwide Digital Commerce at IDC. “Organizations must invest in new tools to keep their application portfolio up to date as they move into the digital era, automating all processes while also leveraging innovation and a wealth of data to become a more creative and resilient company in the digital realm.”

In addition to the ongoing cloud migration, IDC has identified a number of other significant market developments that are driving growth in the enterprise applications market.

  • SaaS and cloud-based, modular, and intelligent applications are no longer “nice to have” but are instead essential for business. Organizations that want to stay in business need AI-driven software that is cloud enabled, modular, and intelligent.
  • Application programmable interface technology will continue to be the backbone of the enterprise applications market. APIs will always resonate as a sound investment to companies that understand the pivotal role they play in connecting all the disparate code bases that make up the modern world.
  • Phasic migration to cloud with TaskApps augmentation will continue, particularly in B2B enterprises. TaskApps and low-code/no-code development tools are being used to close gaps, extend processes, or change up the business at a faster pace throughout the transition to digital first.
  • New global regulations around data privacy and ethics have changed the way organizations collect and use data, pushing governance to the forefront of the conversation. Compliance has become a differentiating factor for enterprises that prioritize trustworthiness.

“The digital world is completely altering the way software is utilized and incorporated into the organization from modularity to APIs to low code/no code to business process automation to TaskApps and even with innovation,” said Mickey North Rizza, group vice president, Enterprise Software at IDC. “Organizations are stretching their visions from filling technology gaps to optimizing processes globally to going the last mile with complete differentiators for their clients. The business world is finally starting to leverage the opportunity technology brings to it.”

The enterprise applications market is a competitive market that includes software specific to certain industries as well as software that can handle requirements for multiple industries. Enterprise applications can be delivered as a pre-integrated suite of applications (featuring common data and process models across functional areas) or as standalone applications that automate specific functional business processes, such as accounting, human capital management, or supply chain execution. The enterprise applications market consists of the following secondary markets: enterprise resource management, customer relationship management, engineering applications, supply chain management applications, and production applications.

The IDC report, Worldwide Enterprise Applications Software Forecast, 2022–2026: Digital Era Software on the Rise (Doc #US48563522), presents a five-year forecast for worldwide enterprise applications revenues, including spending by geographic region and deployment type (public cloud and on premises). The report also provides insight into the market’s evolution through 2026, including deployment models, trends, and significant market developments.


In a separate report titled Worldwide Quarterly Enterprise Infrastructure Tracker: Buyer and Cloud Deployment, IDC sas that spending on compute and storage infrastructure products for cloud deployments, including dedicated and shared IT environments, increased 24.7% year over year in the third quarter of 2022 (3Q22) to $23.9 billion. Spending on cloud infrastructure continues to outgrow the non-cloud segment although the latter had strong growth in 3Q22 as well, increasing at 16.5% year over year to $16.8 billion. The market continues to benefit from high demand and large backlogs, coupled with an improving infrastructure supply chain.

Spending on shared cloud infrastructure reached $16.8 billion in the quarter, increasing 24.4% compared to a year ago. IDC expects to see continuous strong demand for shared cloud infrastructure with spending expected to surpass non-cloud infrastructure spending in 2023. The dedicated cloud infrastructure segment grew 25.3% year over year in 3Q22 to $7.1 billion. Of the total dedicated cloud infrastructure, 45.2% was deployed on customer premises.

For the full year 2022, IDC is forecasting cloud infrastructure spending to grow 19.6% year over year to $88.1 billion – a noticeable increase from 8.6% annual growth in 2021. Non-cloud infrastructure is expected to grow 10.7% to $64.7 billion. Shared cloud infrastructure is expected to grow 19.0% year over year to $60.9 billion for the full year while spending on dedicated cloud infrastructure is expected to grow 21.2% to $27.3 billion for the full year.

Cybersecurity to be a top priority for telcos in 2023

Telecom has always been susceptible to cyberattacks and data breaches.  With increasing deployment of IoT devices, attackers will have more opportunities to obtain our data as more gadgets are connected to our network.  OpenRAN, with many more exposed interfaces, widens the attack surface for bad actors.

Different security risks brought on by 5G will leave the sector open to cyberattacks. To strengthen security surrounding connected devices, cloud systems, and the networks that connect them, telecom operators must invest in implementing stringent cybersecurity measures because there is a significant amount of sensitive data dispersed across intricate, private, and private networks.

According to Gartner, there will be 43 billion IoT-connected devices by the end of 2023. For those in charge of cybersecurity, it’s necessary to keep in mind IoT devices, such as smartwatches or human-wearable biometrics, monitoring systems, robotics, alarm systems, sensors, IT devices, and industrial equipment. IoT security is essential as more telecoms embrace the industry and implement these devices in their networks because they can remotely access base stations and data centers.

Finally, enterprises deploying SD-WANs and other private or virtual private networks. In particular:

  • Secure Access Service Edge (SASE) combines network security functions (such as SWG, CASB, FWaaS and ZTNA), with WAN capabilities (e.g. SD-WAN) to support businesses’ secure access needs. Previously, security for SD-WAN was an open, unresolved issue.
  • Secure Service Edge (SSE) is the security components of SASE focusing largely on the cloud access security broker, secure web gateway, and zero-trust network access products to enable secure use of the internet and cloud services for a hybrid workforce working from anywhere,”  said Gartner analyst Charlie Winckless.

Dell’Oro group July 2022 report found that the SSE market grew 40% year-over-year to more than $800 million in the first quarter.  A December report noted that SSE  achieved its tenth consecutive quarter of sequential revenue expansion in 3Q-2022. Dell’Oro’s Director of Network Security, SASE, and SD-WAN Mauricio Sanchez said the strong growth is a testament to more enterprises preferring cloud-delivered security over traditional on-premises solutions.  Sanchez told SDX Central:  “The growth factors that have existed largely since the pandemic started are still with us.  That’s the shift to hybrid work, the shift of workloads to the cloud, and the importance of the digital experience.”

Have we come full circle – from SD-WAN to SASE to SSE? MEF’s SD-WAN and SASE standards

Have we come full circle – from SD-WAN to SASE to SSE? MEF’s SD-WAN and SASE standards

Backgrounder – SD-WAN and SASE:

software-defined wide area network (SD-WAN) uses software-defined network technology, mostly to communicate over the Internet using overlay tunnels which are encrypted when destined for internal organization locations.  If standard tunnel setup and configuration messages are supported by all of the network hardware vendors, SD-WAN simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. This concept is similar to how software-defined networking implements virtualization technology to improve data center management and operation.[1] In practice, proprietary protocols are used to set up and manage an SD-WAN, meaning there is no decoupling of the hardware and its control mechanism.

A key application of SD-WAN is to allow companies to build higher-performance WANs using lower-cost and commercially available Internet access.  That enables businesses to partially or wholly replace more expensive private WAN connection technologies such as MPLSWhen SD-WAN traffic is carried over the Internet, there are no end-to-end performance guarantees.  In sharp contrast, Carrier MPLS VPN WAN services are not carried as Internet traffic, but rather over carefully-controlled carrier capacity, and do come with an end-to-end performance guarantee.

Gartner’s 2022 SD-WAN Magic Quadrant report identified Cisco, Fortinet, VMware, Palo Alto Networks, Hewlett Packard Enterprise (HPE) Aruba, and Versa Networks as market leaders. The analyst firm estimates the top 10 vendors make up more than 80% of the market.  To determine SD-WAN leaders, Gartner reviewed vendors’ product capabilities such as the ability to operate as a branch office router, and having a centralized management for devices, zero-touch configuration, and VPN with a basic firewall. The analyst firm also reviewed vendors’ business and financial performance based on their volume of customers, sites, and contracts.

Gartner coined the acronym SASE (Secure Access Service Edge) in an August 2019 report The Future of Network Security in the Cloud and expanded its functionality in their 2021 Strategic Roadmap for SASE Convergence.  SASE combines network security functions (such as SWG, CASB, FWaaS and ZTNA), with WAN capabilities (e.g. SD-WAN) to support businesses’ secure access needs. Previously, security for SD-WAN was an open, unresolved issue.

SASE is a holistic framework that brings security and networking connectivity together through a cloud-centric base. Businesses can save equipment, human and financial resources thanks to SASE’s underlying cloud design, and they can scale performance with minimal hardware needs.

Omdia Analyst Fernando Montenegro describes SASE as a “framework architecture, not a solution.”

MEF SD-WAN and SASE Standards:

In August 2019, the MEF published the industry’s first global standard defining an SD-WAN service and its service attributes. SD-WAN Service Attributes and Services (MEF 70). The MEF SD-WAN standard describes requirements for an application-aware, over-the-top WAN connectivity service that uses policies to determine how application flows are directed over multiple underlay networks irrespective of the underlay technologies or service providers who deliver them.  However, it does not address interoperability because it does not specify either a UNI or NNI protocol stack.

MEF 70 defines:

  • Service attributes that describe the externally visible behavior of an SD-WAN service as experienced by the subscriber.
  • Rules associated with how traffic is handled.
  • Key technical concepts and definitions like an SD-WAN UNI, the SD-WAN Edge, SD-WAN Tunnel Virtual Connections, SD-WAN Virtual Connection End Points, and Underlay Connectivity Services.

SD-WAN standardization offers numerous benefits that will help accelerate SD-WAN market growth while improving overall customer experience with hybrid networking solutions. Key benefits include:

  • Enabling a wide range of ecosystem stakeholders to use the same terminology when buying, selling, assessing, deploying, and delivering SD-WAN services.
  • Making it easier to interface policy with intelligent underlay connectivity services to provide a better end-to-end application experience with guaranteed service resiliency.
  • Facilitating inclusion of SD-WAN services in standardized LSO architectures, thereby advancing efforts to orchestrate MEF 3.0 SD-WAN services across automated networks.
  • Paving the way for creation and implementation of certified MEF 3.0 SD-WAN services, which will give users confidence that a service meets a fundamental set of requirements.

Last year MEF introduced an updated version of its SD-WAN standard, MEF 70.1, which added critical enhancements. MEF is also currently at work on version MEF W70.2 and MEF W119 Universal SD-WAN Edge, which will address the need for interoperability, among other things.

In December 2022, MEF published two Secure Access Service Edge (SASE) standards defining 1.] SASE service attributes, common definitions & a framework and 2.] a Zero Trust framework that together allow organizations to implement dynamic policy-based actions to secure network resources for faster decision making and implementation for enterprises.  MEF’s SASE standard defines common terminology and service attributes which is critically important when buying, selling, and delivering SASE services. It also makes it easier to interface policy with security functions for cloud-based cybersecurity from anywhere. MEF’s Zero Trust framework defines service attributes to enable service providers to implement and deliver a broad range of services that comply with Zero Trust principles.

  1. SASE Service Attributes and Service Framework Standard:  specifies service attributes to be agreed upon between a service provider and a subscriber for SASE services, including security functions, policies, and connectivity services. The standard defines the behaviors of the SASE service that are externally visible to the subscriber irrespective of the implementation of the service. A SASE service based upon the framework defined in the standard enables secure access and secure connectivity of users, devices, or applications to resources for the subscriber. MEF’s SASE standard (MEF 117) includes SASE service attributes and a SASE service framework.
  2. Zero Trust Framework for MEF Services: The new Zero Trust Framework for MEF Services (MEF 118) defines a framework and requirements of identity, authentication, policy management, and access control processes that are continuously and properly constituted, protected, and free from vulnerabilities when implemented and deployed. This framework also defines service attributes, which are agreed between a subscriber and service provider, to enable service providers to implement and deliver a broad range of services that comply with Zero Trust principles.



Enter SSE (Secure Service Edge):

In it’s above referenced 2021 report, Gartner defined SSE (Secure Service Edge) which is a separate entity that doesn’t include SD-WAN.  “SSE is the security components of SASE focusing largely on the cloud access security broker, secure web gateway, and zero-trust network access products to enable secure use of the internet and cloud services for a hybrid workforce working from anywhere,” Gartner analyst Charlie Winckless told SDxCentral.

Telefónica tapped cloud security vendor Zscaler to develop a new managed SSE platform in a bid to address changing workforce dynamics and cloud consumption. The announcement illustrated a growing trend around the Gartner-coined product category, in which cloud security and SASE vendors alike announce “new” products and services around the buzzword.

But for the most part, these SSE products aren’t so much new as they’re rebranded and repackaged SASE services that’ve been stripped of their SD-WAN capabilities, if they ever had them in the first place. Zscaler’s SSE is built around the same Zscaler Internet Access and Zscaler Private Access products that, just a few months ago, it was calling SASE.

“The contrast is that SASE focuses on a user’s secure access needs as a part of the solution. SSE, on the other hand, mainly focuses on cloud-centric security services for the protection of users,” according to Juta Gurinaviciute, Forbes Councils Member and CTO for NordLayer, a remote access security provider.  Gurinaviciute explained that SSE is SASE minus SD-WAN. SSE is essentially a way for enterprises to focus more on cloud-based security as a stepping stone to a full SASE service. She wrote:

As per Gartner’s suggestion, some companies may select a single-provider SASE offering, while others prefer partnered SD-WAN and SSE offerings from separate providers based on companies’ needs.   Your business may have already invested in SD-WAN in advance. SSE would be a more meaningful choice in the short-term in such a case. If your company’s current setup doesn’t need SD-WAN, security may be a much more urgent requirement, in which case SSE would make more sense. Even if your organization only has a single regional branch or a simple branch, SSE may still be helpful.

Considering all of these reasons, SASE, the implementation of which may seem challenging and daunting for security professionals, can be done much faster with SSE adaptation first. The journey can be completed much more smoothly using this option, and SSE may benefit a wide range of companies that need robust protection.

“I think everybody’s really excited about SASE because enterprises keep asking about it,” Omdia Analyst Adeline Phua told Light Reading in a recent podcast. “It’s got so much buzz in the market.”  However, Phua found that excitement about SASE/SSE hasn’t necessarily equated to mass adoption of the service. “We’re thinking that maybe adoption is really hitting that tipping point, only to find out when we talk to service providers and to enterprises that the adoption is really not there yet,” she added.

A Dell’Oro group July 2022 report found that the SSE market grew 40% year-over-year to more than $800 million in the first quarter.  A December report noted that SSE  achieved its tenth consecutive quarter of sequential revenue expansion in 3Q-2022. Dell’Oro’s Director of Network Security, SASE, and SD-WAN Mauricio Sanchez said the strong growth is a testament to more enterprises preferring cloud-delivered security over traditional on-premises solutions.  Sanchez told SDX Central:  “The growth factors that have existed largely since the pandemic started are still with us.  That’s the shift to hybrid work, the shift of workloads to the cloud, and the importance of the digital experience.”

While Dell’Oro forecasts the overall SASE market to grow to $8 B for the full year 2023, an Omdia survey found that SD-WAN is only expected to achieve 87% market penetration at the end of 2023. Omdia’ Phua says that enterprises which are using SD-WAN aren’t deploying it at all their sites. Part of the problem stems from supply chain challenges triggered by COVID-19 which have resulted in a shortage of products and SD-WAN deployment delays.

Where service providers can make progress in assisting their enterprise customers’ adoption of SASE is by providing it as a managed service with significant value add “on top of just the staff, the platform itself,” explained Omdia’s Fernando Montenegro. That might look like providing more visibility into network health and potential security threats.

Phua echoed Montenegro’s assessment: “Service providers will still need to keep looking out for new innovations and what else can we onboard to make sure that is a more complete solution for the enterprise customers. So there’s still a lot of way to go in terms of this journey.”

Dell’Oro: SASE Market grew 33% in 2022; forecast to hit $8B in 2023

According to Dell’Oro Group, the ongoing need to modernize the network and security architecture for branch offices and hybrid users led to the vigorous 33% revenue growth in the SASE [1.] market. The market research firm anticipates that enterprises will continue to place a high priority on SASE and cause the overall SASE market to grow to $8B for the full year 2023.  In contrast, Gartner forecasts that total worldwide end-user spending on SASE will reach $9.2 billion in 2023, a 39% increase from 2022.

Note 1.  In 2019, Gartner coined the term secure access service edge, or SASE, that brings a more secure and flexible way to perform advanced security inspection directly in the cloud, instead of backhauling application traffic to a data center before forwarding it to the cloud. This cloud-first approach to security also aligns with the increasing adoption of hybrid work post-pandemic, where workers will balance their time in the office and working remote for the foreseeable future.


“3Q 2022 was the seventh consecutive quarter of year-over-year SASE revenue growth topping 25%, which signals the importance enterprises are placing on SASE,” said Mauricio Sanchez, Research Director, Network Security, and SASE & SD-WAN at Dell’Oro Group. “Unlike some other network security markets we track, we expect the high investment priority will continue and lead to the SASE market eclipsing $8 B in 2023,” added Sanchez.

Additional highlights from the 3Q 2022 SASE & SD-WAN Quarterly Report:

  • SASE security, also referred to as SSE (the basket of products providing cloud-delivered SWG, CASB, ZTNA, and FWaaS), achieved its tenth consecutive quarter of sequential revenue expansion.
  • SASE networking, synonymous with SD-WAN, had a challenging Y/Y comparison in 3Q 2022 against a very strong 3Q 2021 when enormous pent-up demand was a significant driver. Nonetheless, the ongoing trend of improved supply chains allowed vendors to better service demand and sustain a similar level of market growth compared to recent quarters.

Cisco, Fortinet, Palo Alto Networks, Symantec/Broadcom, Versa Networks, VMware and Zscaler are the leading SASE suppliers, according to Del’Oro (see different list below).  However, Sanchez also mentioned another company not typically associated with SASE: Microsoft.

“The dark horse is Microsoft. Not a significant player today, but could easily become one virtually overnight,” he said. “Microsoft – Windows, Azure – has all the technology elements to not only do SASE but compete on a number of other fronts: identity management, firewalls, email/content security, WAF, DDoS, endpoint, cloud security, cloud networking. Moreover, Microsoft has been beating the drum louder about their security capabilities and desire to go after share of security wallet.”

Author’s Note: SASE is a single vendor turn key solution so vendor selection is ultra important.

Definition: SASE (an acronym coined by Gartner) converges network (SD-WAN, ZTNA) and network security services (SWG, CASB, FWaaS, etc). All of these services are integrated and delivered based on user and device identities, context, policies with continuous assessment of risk/trust throughout a session. This combination creates small perimeters around users, devices, and applications, that are then additionally hardened by security services.

Netskope research says that by 2024, at least 40% of enterprises are expected to have explicit strategies for adopting SASE. SASE solutions will help small to large businesses with extracting the security incidents mentioned in the below image. According to MarketWatch, the global SASE market is expected to reach $3936.4 million by 2026.

According to Software Testing Help, the leading SASE vendors are:

To leverage the SASE platform, it should have cloud-native & cloud-based architecture. It should support all edges and be distributed globally across many PoPs (Points of Presence). A SASE platform with significant geographical reach will let you compete effectively and meet the requirements of low latency. A platform with agent-based capabilities can facilitate policy-based access, and some on-premises-based capabilities can provide network functions like QoS.





Secure Access Service Edge (SASE)

Gartner: SASE tops Gartner list of 6 trends impacting Infrastructure & Operations over next 12 to 18 months

Dell’Oro: Secure Access Service Edge (SASE) market to hit $13B by 2026; Gartner forecasts $14.7B by 2025; Omdia bullish on security


Gartner: SASE tops Gartner list of 6 trends impacting Infrastructure & Operations over next 12 to 18 months

At its IT Infrastructure, Operations & Cloud Strategies Conference this week, Gartner identified six trends anticipated to have a significant impact on infrastructure and operations (I&O) over the next 12 to 18 months.   Secure Access Service Edge (SASE) topped the list with Sustainable technology coming in second and Wireless Value Innovation (see below) in third place.

SASE is a single-vendor product that is sold as an integrative service which enables digital transformation. This trend connects and secures users, devices, and locations as they work to access applications from anywhere. Gartner forecasts that total worldwide end-user spending on SASE will reach $9.2 billion in 2023, a 39% increase from 2022.  Gartner coined SASE as a technology framework for the convergence of network access and security in cloud-native environments.  Earlier this year, Gartner released its first Market Guide for Single-Vendor SASE, revealing to I&O leaders that interest in the framework has exploded since its introduction in 2019 – and particularly toward single-vendor solutions.

Gartner VP Analyst Jeffrey Hewitt attributed the fast adoption of SASE to “the need to secure the access of devices and elements at the edge,” as well as hybrid work and a “relentless shift to cloud computing.”  Hewitt noted the primary benefits of the framework are that it allows users to securely connect to applications and improves the efficiency of management.  “Hybrid work and the relentless shift to cloud computing has accelerated SASE adoption,” said Hewitt. “SASE allows users to connect to applications in a secure fashion and improves the efficiency of management. I&O teams implementing SASE should prioritize single-vendor solutions (1.) and an integrated approach.”

Note 1. Single-vendor SASE means the selected service provider owns and delivers all the essential SASE components—software-defined WAN (SD-WAN), secure web gateway (SWG), cloud access security broker (CASB), network firewalling, and zero trust network access (ZTNA)—using a cloud-centric architecture, according to Gartner, which created the term SASE. The service is meant to address shortcomings of legacy methods of securing access to enterprise resources.

“Leaders are going to be looking at this and saying, we want to implement this,” Hewitt told SDxCentral. “They’re going to be assessing and determining what providers can offer.”  I&O teams implementing SASE should prioritize single-vendor solutions, Hewitt added.

Hewitt noted SASE is still an “immature” market and technology framework. “It’s not something that you can just run out and have a large list of vendors – at this point – that you could select from,” he said. While many vendors still can only supply components of SASE, Gartner recognizes nine that offer complete solutions with both networking and Secure Service Edge (SSE) capabilities – Cato Networks, Cisco, Citrix, Forcepoint, Fortinet, Netskope, Palo Alto Networks, Versa Networks, and VMware.

The biggest benefits of a single-vendor solution are improved security posture, administrative simplicity with fewer consoles to manage and troubleshoot, and traffic efficiency due to single-pass encryption and optimal routing decisions instead of needing to integrate between two pieces, Analyst Andrew Lerner told SDxCentral in an earlier interview. Lerner recommended I&O leaders look for single-vendor SASE offerings that provide single-pass scanning, a single unified console, and data lakes covering all functions to improve user experience and staff efficacy.

By 2025, Gartner predicts 65% of enterprises will have consolidated individual SASE components into one or two explicitly partnered SASE vendors, up from 15% in 2021.


Regarding Wireless Value Innovation, Gartner wrote: I&O can leverage multiple wireless technologies to extend business disruption opportunities beyond connectivity. Overlaps between various technologies including Wi-Fi, 5G, Bluetooth and high frequency (HF) facilitates connectivity solutions and creates innovation opportunities.

Hewitt said, “Wireless value innovation creates a scalable return on wireless investment and makes networks a strategic innovation platform. However, there is significant complexity at play and several new skills that are required to achieve this innovation, such as wireless integration capabilities and wireless tracking implementation experience.”

At its recent IT Symposium/Xpo 2022 Gartner included wireless among in its 10 top strategic technology trends for 2023.  In that report, Gartner stated that no single wireless technology will dominate, but enterprises will use a variety of them to support a range of environments, including Wi-Fi in the office, services for mobile devices, low-power protocols, and even radio connectivity, Gartner stated. Gartner predicts that by 2025, 60% of enterprises will be using five or more wireless technologies simultaneously.

“We’re going to see a spectrum of solutions in the enterprise—that includes 4G, 5G, LTE, WIFI 5, 6, 7—all of which will create new data enterprises can use in analytics, and low-power systems will harvest energy directly from the network,” Gartner stated.


Gartner’s top six trends impacting I&O in 2023:

Trend No. 1: Secure Access Service Edge (SASE)

Trend No. 2: Sustainable Technology

Trend No. 3: Platform Engineering

Trend No. 4: Wireless Value Innovation

Trend No. 5: Industry Cloud Platforms

Trend No. 6: Heated Skills Competition

Enterprises Deploy SD-WAN but Integrated Security (SASE) Needed

A new IDC study, commissioned by GTC, reveals that over 95% of enterprises have deployed software-defined wide area networks (SD-WANs) or plan to do so within the next 24 months.  However, nearly half (42%) reported they either don’t have security integrated with SD-WAN or have no specific SD-WAN security at all.

Enterprises today are facing what IDC calls “storms of disruption:” waves of economic, political, and social disruptions that are hampering companies’ efforts to become “truly digital enterprises” – like the Russia-Ukraine war, global recession, and industry-wide skills gaps.  Networks need to support businesses in their move toward a cloud-native, digital-first, hybrid-working model of operation, and SD-WAN is now a cornerstone of network transformation, IDC stated in its GTT-commissioned study.

When asked to list the challenges they faced when taking a do-it-yourself (DIY) approach to SD-WAN, respondents cited difficulties related to hiring and retaining a skilled in-house workforce, keeping up with technology developments and the ability to negotiate favorable terms with technology vendors.

“Now that SD-WAN has matured and has been widely adopted, the complexity of deployments has grown, challenging enterprises on multiple fronts and compromising their ability to realize the full benefits of the technology,” said James Eibisch, research director, European Infrastructure and Telecoms, IDC.

“Enterprises are increasingly reliant on the resources and expertise of a managed service provider to ensure they deploy SD-WAN in a way best suited to their meet their organizations’ objectives. Security approaches like Secure Access Service Edge (SASE) [1.] that combine the benefits of SD-WAN with zero trust network access and content filtering features are well poised to dominate the next phase of SD-WAN enhancements as enterprises continue to enable the cloud IT model and a hybrid workforce.”

Note 1.  SASE, when combined with a SD-WAN overlay network, is seen as a less expensive way to get circuits exactly where they are needed — especially to remote locations — than using traditional architectures like IP-MPLS. Scaling the enterprise WAN out to more user devices and more locations also becomes easier, a necessity at a time when hybrid and remote working continues to be popular.


The IDC survey found that more than 80% of respondents worldwide have either made SASE a priority (39%) or have recognized its benefits and are already incorporating it into company initiatives (42%). Only 19% of respondents worldwide reported they do not view SASE as a priority.

Despite this widespread recognition of the value of integrating security and SD-WAN, the survey found that many enterprises have not been able to leverage these benefits. In the U.S., 45% of respondents said they either don’t have security integrated with SD-WAN or have no specific SD-WAN security at all. In some countries, such as Switzerland and France, that figure was more than 50%. This trend held across vertical industries such as manufacturing (47%), retail (46%), healthcare (47%) and transportation (49%). Financial and business services were exceptions, with only 32% and 34%, respectively.  Seven out of 10 respondents (71%) worldwide expect to use integrated security in the next 12 months.

“This IDC study highlights the critical role of expert managed services support for enterprises deploying SD-WAN. Experienced managed services providers can help integrate technology, connectivity and security, while also managing costs and increased complexity,” said Lisa Brown, CMO at GTT. “The research shows that a DIY approach to SD-WAN presents a number of challenges that can be addressed by teaming with a managed services provider.”

When respondents who were adopting a managed services approach to SD-WAN were asked for their reasons, many said they wanted to outsource day-to-day management tasks. The top reason cited by respondents globally for using a managed services provider was the benefit of always-on help desk support in local languages, with 36% citing this as a reason. Running a close second, 35% cited visibility, insights and control without the need for technology certification as a benefit. In addition, 34% cited ease of configuration management; the ability to manage, maintain and facilitate technology upgrades; and better protection against security threats.

Todd Kiehn, SVP at GTT, told SDxCentral, “There will be a continued evolution to SD-WAN integrated with cloud security over the coming year. The IT organization is going to require ever-increasing visibility into the actions of the end user.  Consistently through our customers, prospects, CIO roundtables and through this recent research, the biggest obstacle enterprises are having in implementing new security solutions is finding and securing a staff with the necessary skills. The cybersecurity skill shortage particularly is a global problem.”

Companies that have no position on SD-WAN-specific security yet face the challenge of adopting these new technologies on their own or through managed service provider partnerships — either of which take time and resources.

“Enterprises can view SASE as a security architecture transformation alongside the deployment of SD-WAN. Our customers are deploying security to support their varied digital transformation initiatives such as work from anywhere, branch transformation or cloud migrations,” Kiehn noted.

“Security solutions based on the SASE framework provide choice and a roadmap to address the specific business needs of the enterprise such as enhancing the security posture of mobile users by replacing legacy VPN technology, improving security for guests and employees at brick and mortar locations, and developing a more comprehensive posture to support a hybrid cloud model,” Kiehn added.

Dell’Oro: Secure Access Service Edge (SASE) market to hit $13B by 2026; Gartner forecasts $14.7B by 2025; Omdia bullish on security

The secure access service edge (SASE) market is expected to triple by 2026, exceeding $13 billion, representing a very healthy CAGR, according to a new forecast by Mauricio Sanchez, Research Director at the Dell’Oro Group.  The report further divides the total SASE market into its two technology components, Security Service Edge (SSE) and SD-WAN with SSE expected to double the SD-WAN revenue for SASE. The report further breaks down the SSE market into FWaaS, SWG, CASB, and ZTNA.

Sanchez wrote in a blog post:

“Today, enterprises are thinking differently about networking and security. Instead of considering them as separate toolsets to be deployed once and infrequently changed, the problem and solution space is conceptualized along a continuum in the emerging view. The vendor community has responded with a service-centric, cloud-based technology solution that provides network connectivity and enforces security between users, devices, and applications.

SASE utilizes centrally-controlled, Internet-based networks with built-in advanced networking and security-processing capabilities. By addressing the shortcomings of past network and security architectures and improving recent solutions—in particular, SD-WAN and cloud-based network security—SASE aims to bring networking and security into a unified service offering.

While the networking technologies underpinning SASE are understood to be synonymous with well-known SD-WAN, the security facet of SASE consists of numerous security technologies, such as secure web gateway (SWG), cloud access security broker (CASB), zero-trust network access (ZTNA), and firewall-as-a-service (FWaaS). Recently, a new term, security services edge (SSE), emerged to describe this constellation of cloud-delivered network security services that is foundational in SASE.”

As noted above, Dell’Oro  divides the total SASE market into two technology components: Security Service Edge (SSE) and SD-WAN with SSE. Security features such as Firewall-as-a-Service (FWaaS), Secure Web Gateway (SWG), Cloud Access Security Broker (CASB) and Zero Trust Network Access (ZTNA) fall under the umbrella of SSE, according to Dell’Oro. In addition, Dell’Oro predicts that the security component to SASE “will increasingly be the driver and lead SASE’s SSE to exhibit over twice the growth of SASE’s SD-WAN.”

Dell’Oro’s Sanchez wrote, “We see SASE continuing to thrive independent of the ongoing macro-economic uncertainty as enterprises strategically invest for the new age of distributed applications and hybrid work that need a different approach to connectivity and security.  We anticipate that security will increasingly be the driver and lead SASE’s SSE to exhibit over twice the growth of SASE’s SD-WAN.”

Additional highlights from SASE and SD-WAN 5-Year Forecast Report:

  • Within SSE, Secure Web Gateway (SWG) and Cloud Access Security Broker (CASB) are expected to remain the most significant revenue components over the five-year forecast horizon, but Zero Trust Network Access (ZTNA) and Firewall-as-a-Service (FaaS) are estimated to flourish at a faster rate.
  • Unified SASE is expected to exceed disaggregated SASE by almost 6X.
  • Enterprise access router revenue is expected to decline at over 5 percent CAGR over the forecast horizon.

Dell’Oro expects that under the umbrella of SSE, Secure Web Gateway and Cloud Access Security Broker will continue as the most significant revenue components over the five-year forecast horizon. However, Zero Trust Network Access and Firewall-as-a-Service are expected to grow at a faster rate.

Unified SASE, which Dell’Oro qualifies as the portion of the market that delivers SASE as an integrated platform, is expected to exceed disaggregated SASE by almost a factor of six over the next five years. The disaggregated type is defined as a multi-vendor or multi-product implementation with less integration than unified type.  Dell’Oro also predicts that enterprise access router revenue could decline at over 5% CAGR by 2026.


Gartner has a more optimistic forecast of SASE revenue, predicting the market to reach $14.7 billion as early as 2025.  “Gartner predicts that global spending on SASE will grow at a 36% CAGR between 2020 and 2025, far outpacing global spending on information security and risk management,” reported VentureBeat last month. According to Gartner, top SASE vendors include Cato Networks, Fortinet, Palo Alto Networks, Versa Networks, VMware and Zscaler.

These disparate predictions could be a result of the nascent nature of the SASE market, a convergence of networking and security services coined by Gartner in 2019. To address the varying definitions for SASE and resulting confusion on the part of enterprise customers, industry forum MEF plans to release SASE (MEF W117) standards this year. MEF started developing its SASE framework in 2020 to clarify service attributes and definitions. (See MEF adds application, security updates to SD-WAN standard and MEF’s Stan Hubbard on accelerating automation with APIs.)


Omdia’s [1.]research also shows security is a major driver for SASE adoption, according to Fernando Montenegro, senior principal analyst with Omdia.  “Our own research indicates that end-user organizations value secure web browsing use cases (SWG, CASB, browsing isolation) particularly as they go further into their deployments of SASE projects,” said Montenegro in an email to Light Reading.

Note 1.  Omdia and Light Reading are owned by Informa in the UK

Security is critical for organizations in what Omdia calls the age of “digital dominance” and by how the “demands on security teams – both in terms of time and expertise – make the delivery of security functionality via a services model particularly attractive,” Montenegro said.

SASE services also provide “good performance characteristics” when compared to enterprises utilizing their own VPN headends, and especially when hybrid work continues to be popular, added Montenegro.



Total SASE Market to Nearly Triple by 2026, According to Dell’Oro Group





MEF survey reveals top SD-WAN and SASE challenges

The Metro Ethernet Forum (MEF) conducted a survey which showed that the top SD-WAN and SASE challenges are focused on coping with operating a multi-vendor environment. That’s to be expected since there are no standards for multi-vendor interoperability for either of those technologies. MEF surveyed 36 worldwide service provider experts to obtain its results.

The complexity of operating and managing multi-vendor SD-WAN, integrating security options and defining end-to-end service level agreements (SLAs) were the top three challenges.

The top Secure Access Service Edge (SASE) challenges focus more on education and standardization. The top challenges service providers face with SASE are the lack of industry standards, customer education and migration, vendors not offering a complete solution and operating in a multi-vendor environment.

MEF’s research also shows that both SD-WAN and SASE markets are on track to hit analyst expectations. “The global SD-WAN services market should hit double-digit revenue growth in 2022, while most providers who offered SASE in 2021 expect 50%-plus revenue growth in 2022 due to a significant uptick in rollout of SASE services and features,” MEF Principal Analyst Stan Hubbard told SDxCentral via email.

All service providers surveyed already have elements of a SASE offering or plan to introduce a SASE solution in 2022, according to this MEF survey.

“The top SD-WAN and SASE service provider challenges are in line with expectations for the different stages of these markets, On the SD-WAN front, one of the biggest aggravations for providers is the complexity of operating a multivendor environment, which is primarily due to the absence of interoperability among SD-WAN technology vendors. Providers have told us that their need to develop and maintain expertise on various SD-WAN vendor solutions increases skills and training burdens, creates operational inefficiencies, and adds costs. The situation is made worse today because the terminology, architectures, performance metrics, etc., of vendors differ since they do not all adhere to common standards,” Hubbard wrote.

“The SASE services market is in its very early days, confusing, and full of a host of challenges related to customer education, customer migration, lack of industry standards, the lack of complete SASE vendor solutions and more. Multiple service providers agreed the organizational challenge of integrating networking and security is ‘huge’ for customers migrating to a SASE solution. As a large service provider stated, “SASE will be a failure without organizational change” within both customers and service providers,” Hubbard added.
