Single-Vendor SASE to Represent 90 Percent of $17 Billion Market in 2029, According to Dell'Oro Group

AI-Ready, Zero-Trust SASE Platforms Driving Adoption

REDWOOD CITY, Calif., July 30, 2025 /PRNewswire/ -- According to a recently published forecast report from Dell'Oro Group, the trusted source for market information about the telecommunications, security, networks, and data center industries, the global Secure Access Service Edge (SASE) market is forecast to rise to $17 B by 2029, representing a 12 percent compound annual growth rate (CAGR). Enterprises continue to invest in branch and hybrid-work modernization with cloud-delivered security, pervasive encryption, and AI-assisted threat defense—capabilities that demand an integrated networking-and-security fabric enforcing zero-trust principles without sacrificing performance. Vendors that offer both the security and networking sides of SASE stand to represent 90 percent of the overall market as preferences shift to consolidated SASE platforms.

"The rapid expansion of AI workloads and escalating data security pressures are accelerating Security Service Edge (SSE) adoption and compelling enterprises to rethink perimeter-centric defenses," said Mauricio Sanchez, Sr. Director, Enterprise Security and Networking at Dell'Oro Group. "When combined with SD-WAN's application-aware routing, SASE gives IT teams the agility to secure users and data everywhere while modernizing WAN economics—all of which demand a tightly integrated networking-and-security fabric capable of enforcing zero-trust principles without compromising performance," added Sanchez.

Additional highlights from SASE and SD-WAN 5-Year July 2025 Forecast Report:

• SSE: Revenue is forecast to nearly double, reaching $11 B in 2029.
• SD-WAN: After suffering a slight correction in 2024 following the surge in spending during the pandemic, market momentum is rebounding and expected to put revenue on a 9 percent CAGR course through 2029.
• Unified SASE: SASE offerings that implement SD-WAN and SSE capabilities in a unified technology stack are forecast to achieve 27 percent revenue CAGR, which is more than twice the market average.
• Access Router: Spending is anticipated to contract 10 percent annually, as enterprises retire fixed-function hardware in favor of SASE-optimized platforms.
