sase

SASE is an acronym with multiple uses in different domains. In everyday correspondence, it refers to a self-addressed stamped envelope used to request a reply. In information technology, SASE stands for Secure Access Service Edge, a cloud-delivered framework that unifies networking and security services for remote or distributed organizations.

In mail contexts, a SASE is typically provided by the requester when sending a letter that requires a response. The sender includes a return envelope with their address and sufficient postage so the recipient can mail back documents, forms, or information without incurring postage costs. It has largely declined with digital communication, though it remains used in some formal or archival processes.

In information technology, Secure Access Service Edge is a cloud-native framework defined by Gartner as the convergence of software-defined wide-area networking (SD-WAN) with a set of security services delivered from the cloud. A SASE architecture typically combines secure web gateway, cloud access security broker, zero-trust network access, and firewall as a service to enforce consistent security policies for users and devices, anywhere. It aims to simplify management for distributed organizations and provide uniform security controls regardless of location.
