Secure Access Service Edge (SASE) is a cloud-based architecture that combines network security and wide-area networking (WAN) into a single, unified service.

SASE integrates various security functions such as secure web gateways (SWG), cloud access security brokers (CASB), firewalls, and zero trust network access (ZTNA) with software-defined networking (SD-WAN) capabilities.

SASE is designed to meet the needs of modern, distributed workforces by providing security closer to the edge of the network, rather than relying on traditional data center-based security models.
