Gartner defined the 3rd generation of network architecture: Secure Access Service Edge (SASE). Here are the 4 key components of a SASE model:

SASE Cloud: the SASE cloud is a globally distributed cloud service built for all traffic and security requirements and from all edges – physical, mobile and cloud. It’s a single entity and its internal structure entirely transparent to end-users.

Point of Presence (PoP): A specific network interface point between communicating entities. SASE PoPs are symmetrical, interchangeable, multi-tenanted and built to serve any enterprise edge connected through them.

SASE Edge: The SASE edge is designed to connect to the SASE cloud. SASE clients include SD-WAN appliances for branches, IPSEC-enabled firewalls, routers and device agents for Windows, Mac, iOS, Android and Linux.

SASE Management: A cloud-based console that provides a single-pane-of-glass management solution to manage, configure and analyse all policies, security and devices.

The components of SASE are not all new, but they are converged into one unified, cloud-native solution to produce a powerful network and security architecture. Understand the power of SASE
