Zscaler at a glance

Zscaler is the cybersecurity platform for the AI age — built on Zero Trust to protect users, workloads, branches and devices through the world's largest inline security cloud.

Zscaler is delivered as SaaS (Software as a Service) — a cloud subscription with no security appliances to deploy or operate. Every security function is served from the Zscaler cloud, so there is no hardware to buy, scale or patch, and users receive the latest security policy wherever they are.
