Secure access service edge (SASE) is a framework for network architecture that brings cloud native security technologies—SWG, CASB, ZTNA, and FWaaS in particular—together with wide area network (WAN) capabilities to securely connect users, systems, and endpoints to applications and services anywhere.

Modern digital business models are allowing new levels of customer and employee engagement by delivering globally available access to applications and services that is consistent, no matter where employees and customers connect or what devices they are using. The notion of network security when your users and applications are distributed is no longer viable in a digital world. Gartner developed a new model of networking and security that matches the requirements of the digital enterprise. They're calling it the secure access service edge (SASE).
