Secure Access Service Edge
(SASE)
A cloud-delivered architecture that combines network connectivity and security services into a single service.
Definition
Secure Access Service Edge (SASE) is a cloud-delivered architecture that combines wide-area network connectivity (typically SD-WAN) with security services like firewall, secure web gateway, CASB, and zero-trust network access into a single integrated service. SASE replaces the traditional model of routing all traffic back to a central data center for inspection, reducing latency and complexity. The term was coined by Gartner in 2019 and has become the dominant architecture for distributed enterprises with remote workforces.
