SSA vs SASE vs SSE

SSA, Secure Access Service Edge (SASE), and Security Service Edge (SSE) are all terms for converged, cloud-native security solutions. These offerings primarily differ in what solutions they offer.

For example, both SSA and SASE integrate network security solutions (CASB, FWaaS, SWG, and ZTNA) and SD-WAN. However, SSA solutions also require EDR, XDR, and NDR, while SASE solutions also have additional network optimization functionality built in. SSA differs from SSE in that SSA integrates SD-WAN and endpoint security functionality. SSE solutions focus solely on cloud network security solutions such as CASB, SWG, and ZTNA.

In general, a single solution may tick the boxes for several of SSA, SASE, and SSE. However, certain solutions may be designed for particular use cases and offer a subset of the possible features.
