SASE is a technology framework that guides enterprises through the converging trends in secure networking, replacing secure perimeters with a cloud-native service that enforces policies at the network's edge. It represents the convergence of five technologies: Software-Defined Wide Area Networking (SD-WAN), Firewall-as-a-Service (FWaaS), Secure Web Gateway (SWG), Cloud Security Broker (CASB), and Zero-Trust Network Access (ZTNA). Gartner's SASE future identified these five converging technologies. However, few offer a complete solution today, and none offer truly cloud-native solutions.
