Secure access service edge, or SASE, combines networking and security into a cloud-based service, and it’s growing fast. According to Gartner projections, enterprise spending on SASE will hit almost $7 billion this year, up from under $5 billion in 2021. Gartner also predicts that more than 50% of organizations will have strategies to adopt SASE by 2025, up from less than 5% in 2020.
The five core components of the SASE stack are SD-WAN, firewall-as-a-service (FWaaS), secure web gateway (SWG), cloud access security broker (CASB), and zero trust network access (ZTNA).
