Secure Access Service Edge (SASE) Explained
Security Architecture & EngineeringCISSPCySA+
Your users work from anywhere, and your apps live in the cloud, so sending every connection back through the office no longer works. In this video, I'll walk through SASE (secure access service edge): how users and sites reach the nearest point of presence, how SD-WAN and the SSE security services work together, why one policy matters, and where SASE has limits.
What you will learn
- What SASE is, and why VPN backhauling to the data center stopped working
- The building blocks: users and sites, apps, and points of presence (PoPs)
- SD-WAN, the networking half of SASE
- SSE, the security half: SWG, CASB, FWaaS and ZTNA
- One policy in one console, and direct paths with no backhaul
- Limits: vendor lock-in, provider outages and legacy systems
- Three tip ideas: SASE ≠ one product; SSE ≠ SASE; zero trust ≠ SASE
