Secure access service edge (SASE) is a methodology for secure connectivity to resources in the cloud and on-premise that combines WAN capabilities and network security. These technologies include: Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Firewall as a Service (FWaaS), and Zero Trust Network Access (ZTNA) to support dynamic, secured access. Half network and half security, the SASE framework is designed to allow enterprise security professionals to apply identity and context to specify the level of performance, reliability, security, and cost desired for every network session. SASE, in simplistic terms, is a methodology to accomplish Zero Trust policies in a cloud-native architecture.
Organizations using SASE can derive increased speed and greater scale in the cloud while at the same time address security challenges that come with distributed cloud-based environments. SASE takes a Zero Trust approach, which is “verify, then trust” rather than simply trusting users on the network by default. It emphasizes the protection of critical IP and strict identity verification for every user and device regardless of location or network zone. This enables segmentation and control over each user and application explicitly.
