Enterprises have spoken and are favoring single-vendor Secure Access Service Edge (SASE) solutions. SASE is a technology used to deliver vast area network and security controls as a cloud computing service directly to the source of connection rather than a data center.
According to Dell’Oro, single-vendor SASE solutions will grow at twice the rate of multi-vendor SASE solutions. The research firm said enterprises are anticipated to spend nearly $34 billion between 2022 and 2027 on single-vendor SASE solutions.
While multi-vendor SASE solutions are projected to grow slower, they will continue to occupy a significant part of the SASE market, with enterprise spend expected to be $29 billion during the forecast period.
Whether single- or multi-vendor, Dell’Oro forecasts that total spending on SASE solutions will exceed $63 billion between 2022 and 2027. Further, unified SASE is anticipated to grow at a five-year compound annual growth rate (CAGR) of over 30 percent between 2022 and 2027, over twice the disaggregated SASE rate.
Dell’Oro’s report further divides the total SASE market into two components: Security Service Edge (SSE) and SD-WAN and details how the substantial spend on both is expected to drive SD-WAN annual spending to nearly $6 billion and SSE spending to over $8 billion by 2027.
One of the critical elements of SD-WAN growth is that SD-WAN sales to service providers that offer managed SD-WAN will continue to outpace SD-WAN sold to enterprises that self-manage.
“Since we started tracking the SASE market in 2019, multi-vendor solutions have represented most of the market compared to single-vendor. However, in 2023 we anticipate that single-vendor SASE will become most of the market,” said Mauricio Sanchez, senior director of enterprise security and networking at Dell’Oro Group. “As single-vendor SASE solution maturity increases, so is the comfort in purchasing it all from a single vendor.” He added that “the pressure to go after best-of-breed from multiple vendors is slowly diminishing.”
