SaaS- and Virtual-Based Network Security Revenue to Eclipse Hardware by 2026, According to Dell’Oro Group


Cloud Applications and Hybrid Work Driving Seismic Shift


REDWOOD CITY, Calif. – February 3, 2022 – According to a recently published report from Dell’Oro Group, the trusted source for market information about the telecommunications, networks, and data center IT industries, demand for software-as-a-service (SaaS)- and virtual-based is anticipated to represent 51 percent of the $33 B total Network Security market revenue in 2026.


“Since the arrival of the first network security appliances in the 1980s, the Network Security market has been dominated by an assortment of purpose-built boxes, but we see a seismic shift taking place,” said Mauricio Sanchez, Research Director, Network Security at Dell’Oro Group. “Between enterprises embracing cloud applications and hybrid work as the new normal, we see them preferring SaaS- and virtual-based network security solutions that serve these use cases better. This is not to say that we see hardware security appliances disappearing, but they no longer represent the vanguard of network security they once were,” added Sanchez.

  • SaaS- and virtual-based web application firewalls (WAFs), a vital capability of cloud workload security solutions, are anticipated to experience a compounded annual growth (CAGR) of 25 percent from 2021 to 2026.

  • SaaS-based secure web gateways (SWGs), fundamental in the Secure Access Service Edge (SASE) architecture, are forecasted to grow at 23 percent CAGR from 2021 to 2026 as hybrid work becomes more commonplace.
