Zscaler’s SASE (Secure Access Service Edge) solution, called Zero Trust SASE, unifies networking and security in a cloud-native platform built on zerotrust principles. It combines next-gen SDWAN with comprehensive security services — like Secure Web Gateway (SWG), FWaaS (Firewall-as-a-Service), CASB, ZTNA, and DLP — to inspect and secure all traffic close to the user. By routing traffic through its Zero Trust Exchange,Zscaler avoids backhauling to data centers, optimizes performance, and applies consistent security policies globally. Their architecture uses AI to continually assess risk, reducing complexity and cost while protecting users, devices, and applications from advanced threats.
