Not to sound like a broken record, but IT leaders must rethink their security strategies to reliably protect sensitive data and ensure business continuity. The main reason? Namely, the threat landscape expands often, especially with organizations relying on cloud-based applications and remote workforces.

In response to this, the SASE market has gained a lot of traction. Organizations seek to simplify their IT infrastructure while bolstering their defenses. As SASE adoption accelerates, the market presents new opportunities and challenges for vendors and customers alike.

A new report from Dell’Oro Group provides analysis of the SASE market’s growth. According to the forecast provided by the Dell’ (News - Alert)Oro Group, the SASE market is poised to reach nearly $16 billion by 2028. This represents a compound annual growth rate, or CAGR, of 13%.

What stood out to me in the report, however, was the contrast between the SSE and SD-WAN segments. While SSE is anticipated to maintain double-digit growth, SD-WAN’s expansion is projected to slow to single digits over the next five years.

Despite challenges such as lengthened sales cycles due to macroeconomic factors, the SSE market is expected to rebound in 2025 as purchasing sentiment improves. However, the SD-WAN market faces headwinds from post-pandemic spending adjustments and a maturing market.

“The divergence in growth between SSE and SD-WAN highlights a shift in enterprise priorities,” said Mauricio Sanchez, Senior Director of Enterprise Security and Networking at Dell'Oro Group. “As enterprises become increasingly cloud- and mobile-first, the demand for integrated security solutions is driving the rapid adoption of SSE.”

Another thing that stood out in the report is the dominance of single-vendor SASE solutions. By 2028, these offerings are projected to account for over 85% of the market. Enterprises are increasingly favoring integrated, one-stop solutions that simplify deployment and management.

Within the single-vendor SASE segment, unified SASE solutions are particularly promising. These solutions, which combine networking and security features into a single package, are expected to grow at a 19% CAGR. Smaller enterprises are driving this growth because they seek simplified and cost-effective solutions.

And, as SASE gains traction, the traditional access router market is facing decline. Revenue from access routers is expected to drop below $1 billion by 2028, which reflects a double-digit CAGR decline as enterprises migrate to SD-WAN solutions.

“Despite an expected slowdown in SD-WAN growth, the overall SASE market remains strong and poised for continued expansion,” Sanchez added.

We're aware that the widespread adoption of SASE will contribute to a more secure and efficient business environment. Looking at this bigger picture, though, SASE's growth will have far-reaching economic implications. Increased IT spending on SASE solutions is expected to spur job creation in related fields and stimulate broader economic growth.

As the market matures, we can anticipate intense competition among vendors. This will only drive innovation and potentially lead to market consolidation.
