SAN JOSE, Calif.–(BUSINESS WIRE)–#DellOro–Versa Networks, the recognized secure access service edge (SASE) leader, today announced that it has been listed as the unified SASE market share leader for 2021 with 84-percent market share, according to the Dell’Oro Group 4Q21 Network Security Quarterly Report published this month. Dell’Oro Group is the trusted source for market information about the telecommunications, networks, and data center IT industries.

Dell’Oro Group’s inaugural SASE market share ranked Versa as the number one unified SASE vendor, based on 2021 worldwide revenue. Dell’Oro Group defines unified SASE, which is the recognized future of the SASE market, as networking and security services integrated in a single platform with all SASE components coming from the same vendor; and implementing a single policy repository that spans network and security policy. According to Dell’Oro Group, unified SASE grew faster at 48 percent year over year in 2021 than disaggregated SASE, at 37 percent. Unified SASE is also expected to outpace disaggregated SASE, with a five-year CAGR of 56 percent, compared to 15 percent for disaggregated SASE. The report also revealed that the worldwide SASE market, as based on the sum of the networking and security components, was $1.2B in 4Q21, equating to a 27 percent rise, and $4.2B for full-year 2021, representing growth of 37 percent.

“As a result of Versa’s market performance, we are pleased to award the company with Dell’Oro Group’s Market Share Leadership Award for unified SASE,” said Mauricio Sanchez, Research Director at Dell’Oro Group. “We see SASE as a service-centric, cloud-based solution that brings networking and security into a unified service architecture. On a technology level, we see it as the combination of SD-WAN networking and numerous security technologies, such as SWG, CASB, ZTNA, and FWaaS.”

“There has been a lot of buzz about SASE over the past two years,” said Michael Wood, Versa Networks Chief Marketing Officer. “Versa’s unique set of comprehensive SASE services have been recognized as leading the industry, and it’s rewarding to see our market leadership validated in Dell’Oro Group’s recent report, the first of its kind in the industry. Versa’s leadership is simple. Our products were architected 10 years ago to tightly integrate the security and networking functionalities that organizations need, which later would make up the SASE market category. Versa’s single-stack architecture uniquely delivers the tightly integrated security and networking functionalities desired by organizations. Demand for Versa SASE has rocket shipped over the past 24 months, as organizations have looked to Versa as a strategic partner to address their complex secure access, networking and digital transformation needs.
