About Zscaler

Zscaler is a commercial cloud security provider built around its Zero Trust Exchange. Instead of routing users through a corporate network, it places a cloud service between users, devices and workloads and the applications they reach, so access decisions are made per connection. It targets enterprises moving away from VPNs and perimeter firewalls.

The platform includes Secure Internet Access for web and SaaS traffic, Secure Private Access for internal apps without a VPN, Zero Trust Branch, Zero Trust Cloud, Digital Experience monitoring, a zero trust browser, cloud sandbox, a zero trust firewall and privileged remote access. The vendor also promotes data security, security for AI and agentic security operations.

Zscaler is proprietary and delivered entirely as a cloud service through regional cloud portals, so there is nothing to host yourself. Customers typically request a demo, and the vendor publishes a pricing and plans page that outlines how the offering is packaged.
