SASE vs. SSE
Security Service Edge (SSE) is a term defined by Gartner as a subset of SASE that focuses specifically on the security services: SWG, CASB, ZTNA, and FWaaS. While SASE combines both networking (SD-WAN) and security services, SSE focuses exclusively on the security components.
When to use SSE vs. SASE
SSE is appropriate for organizations that already have an SD-WAN solution and want to add cloud-delivered security. SASE is ideal for organizations looking to converge both networking and security into a single platform.
Components of SSE
SSE includes secure web gateway (SWG), cloud access security broker (CASB), zero trust network access (ZTNA), and firewall as a service (FWaaS) — all delivered from the cloud.
