SASE
acronymnetworkingsecuritycloud
Stands for: Secure Access Service Edge
Gartner's 2019 model that converges the WAN and its security stack into a single cloud-delivered service at the edge, as close to the user as possible.
Coined by Gartner analysts Neil MacDonald, Lawrence Orans, and Joe Skorupa in 'The Future of Network Security Is in the Cloud' (August 30, 2019) and pronounced 'sassy', SASE bundles SD-WAN with secure web gateway, CASB, zero trust network access, and firewall as a service, delivered from distributed points of presence and driven by identity rather than by the address of a data center. The pitch: stop backhauling a remote workforce through headquarters appliances and put both the network path and its inspection where the users and the SaaS already are. The term reorganized the vendor market within two years, and in 2021 Gartner carved out the security half under its own name, SSE, for buyers who wanted the protection without coupling it to the SD-WAN decision.
