Secure Access Service Edge (SASE) is a network architecture that combines wide-area networking (WAN) capabilities with comprehensive security services, such as secure web gateways (SWG), cloud access security brokers (CASB), firewalls as a service (FWaaS), and zero trust network access (ZTNA), into a single, cloud-delivered service model. SASE enables secure and efficient connectivity for users, devices, and applications, regardless of location.
