SASE Market Hits $2.4 Billion, Top Vendors Tighten Market Share Grip
The global Secure Access Service Edge (SASE) market reached $2.4 billion in the third quarter of 2024, with six leading vendors — Zscaler, Cisco, Palo Alto Networks, Broadcom, Fortinet and Netskope — capturing a combined 72% market share.
This marks a 7-point year-over-year (Y/Y) gain for these dominant players, according to the latest Dell’Oro Group report.
Zscaler maintained its leadership position with a 21% market share, driven by its commanding 34% share in the Secure Service Edge (SSE) segment.
Cisco led the SD-WAN market with a 31% share, leveraging its networking depth to solidify its position.
However, overall SASE market growth slowed to single digits Y/Y, the lowest since tracking began in Q1 2019.
Despite this, the top vendors outpaced the market with double-digit growth.
“Leading vendors have succeeded by delivering depth, breadth and proven reliability,” said Mauricio Sanchez, senior director of enterprise security and networking at Dell’Oro Group. “This consolidation highlights the market’s maturity as enterprises increasingly prioritize established players with comprehensive solutions.”
Sanchez noted several factors contributing to the dominance of the top six vendors.
“Depth of SASE capabilities, extensive portfolios and entrenched customer relationships give these leaders an edge,” he said.
For example, Zscaler’s long-standing focus on cloud security innovation and Cisco’s expertise in networking infrastructure allows them to deliver robust, enterprise-grade solutions.
Sanchez said the slow growth in the broader SD-WAN market, which saw only a 1% Y/Y increase, reflects the segment’s maturation as enterprises focus on optimizing existing deployments rather than expanding.
“After nearly a decade of transforming enterprise branch networking, most large organizations have completed their initial SD-WAN rollouts,” he explained. “Now, they’re optimizing deployments to prepare for the next wave of architectural changes, including the integration of distributed AI workloads.”
In contrast, the SSE market experienced robust 14% Y/Y growth, fueled by the increasing appeal of cloud-delivered security solutions.
“The efficiency of the cloud delivery model, both in feature deployment and monetization, has been a game-changer,” Sanchez said. “Enterprises are solving real-world challenges with these advanced capabilities, making SSE a cornerstone of modern security strategies.”
While the dominance of major players highlights the market’s maturity, he said there is still room for smaller vendors to carve out niches.
Cato Networks, for example, achieved nearly 50% growth in Q3 2024 by balancing features and simplicity.
“This approach resonates with mid-sized enterprises still evaluating their SASE strategies,” Sanchez explained.
Looking ahead to 2025, the SASE market is expected to see moderate growth, supported by improving economic conditions and technological advancements.
“The anticipated moderation in inflation and interest rates should boost enterprise investment confidence, particularly in North America, which accounts for over half of global SASE revenue,” he said.
He also pointed to emerging opportunities in APAC, where SASE adoption is accelerating, and the increasing role of AI in driving innovation.
“Enterprises are beginning to view SASE not only as infrastructure for distributed AI workloads but also as a platform that leverages AI for security and networking optimization,” Sanchez said. “Vendors who can demonstrate operational efficiency gains while supporting emerging use cases will be best positioned to capture future growth.”
Sanchez noted that anticipated moderation in inflation and interest rates should improve enterprise investment confidence, particularly in North America which represents over half of worldwide revenue.
“However, the most interesting dynamic may be the growth potential in regions outside North America, especially in APAC where SASE adoption is accelerating,” he said.
