Secure access service edge, or SASE (pronounced ‘sassy,’), is a framework defined by Gartner in 2019 as a way to securely connect entities, such as users and machines, to applications and services-from anywhere. SASE combines wide-area networking (WAN) capabilities with security functions, such as SWG, CASB, FWaaS, and ZTNA, into a single cloud-based solution that’s delivered as a service. Services are delivered at the ‘edge’ of a distributed cloud architecture, pushing them as close as possible to users for a fast experience with the fewest hops. At a time when workers are increasingly working remotely and off the corporate network, SASE assists organizations in making a secure, seamless transition to the cloud from legacy hardware in data centers, while securing access to cloud applications and reducing costs.
