Secure Access Service Edge (SASE) and Security Service Edge (SSE) have become the dominant architecture for delivering cloud-based network security. This ranking evaluates the leading platforms that combine ZTNA, CASB, SWG, and other security services into unified cloud-delivered solutions.
What is SASE vs SSE?
| Term | Definition | Components |
|---|
| SSE | Security Service Edge | ZTNA + CASB + SWG + FWaaS |
| SASE | Secure Access Service Edge | SSE + SD-WAN |
SSE focuses purely on security services, while SASE adds networking (SD-WAN) for a complete solution.
