Secure Access Service Edge (SASE) combines networking and security into a single cloud-delivered service, replacing the patchwork of VPNs, firewalls, and proxies that most enterprises still use.
SASE Components
- SD-WAN: intelligent traffic routing
- ZTNA: zero trust network access (replaces VPN)
- CASB: cloud access security broker
- SWG: secure web gateway
- FWaaS: firewall as a service
Gartner predicts 60% of enterprises will adopt SASE by 2028. Leaders include Zscaler, Palo Alto Prisma, and Cloudflare One. Average deployment takes 6-12 months with 30-40% reduction in security tool spending.
