The shift to cloud and mobile-friendly IT will drive secure access service edge (SASE) implementation to double yearly through 2025.

That’s according to Dell’Oro Group’s updated SASE advanced research report. It addresses key topics, including key market drivers behind SASE, SASE architecture, the SASE technology vendor landscape and more.

Additional highlights from the SASE report include:

  • The number of SASE technology vendors has grown from a handful to 35.

  • Over the past year, communications service providers have rapidly embraced SASE. That’s due to many technology vendor choices, the ease and low risk of deployment, and new revenue potential.

  • Two major SASE implementation types exist in the market. Those are unified and disaggregated. Unified consists of single-vendor, tightly integrated SASE platforms. Disaggregated is a multivendor or multiproduct implementation with less integration than unified. Unified will grow faster than disaggregated, but not surpass it by total revenue through 2025.

Vendor Community Responding

“As enterprises pivot toward becoming cloud-first and mobile-friendly, they are running into the structural deficiencies of the hub-and-spoke model and need alternatives,” he said. “The need for more agility, better scalability and ubiquitous security has driven the vendor community to respond with the convergence of SD-WAN and secure web gateway (SWG) solutions into a new architecture under the SASE umbrella. As a result, enterprises’ interest in SASE is skyrocketing.”

In mid-2019, SASE emerged as a new vision to unify the networking and security worlds. It has since then “thoroughly captivated” the network and security industry, according to Dell’Oro.

Since the arrival of SASE, the number of vendors touting SASE solutions and technologies has exploded, Sanchez said.

“Confusion is rampant as vendors interpret SASE differently to fit their current solutions and strategies best,” he said. “Understanding which vendors deliver on the SASE vision is difficult. And sizing the market opportunity is next to impossible.”

Dell’Oro believes SASE implementation does not require an entirely new set of technologies. Instead, it’s the amalgamation of existing networking and security technologies.
