Zscaler Zero Trust Firewall

Cloud-delivered firewall in the Zscaler Zero Trust Exchange (Zscaler Internet Access) that inspects web and non-web traffic on all ports and protocols, including TLS decryption. Zero trust is a security strategy in which entities are granted access based on context and security posture—not assumed trust. Built on a cloud native platform, a zero trust firewall protects web and non-web traffic for all users, apps, locations, and clouds. SSE core services include secure web gateway (SWG), zero trust network access (ZTNA), cloud access security broker (CASB), and firewall as a service (FWaaS). It is available as a cloud instance.

Zscaler was founded in 2007 by Jay Chaudhry on the argument that if applications and users have both left the office, the security stack should leave too. It built a global network of data centres through which customer traffic is routed, inspected and forwarded — the Zero Trust Exchange — and sells access to that network instead of appliances. It is listed on Nasdaq and is one of the largest security companies by market value. Zscaler Zero Trust Firewall, the product here, is the firewalling layer of that service: policy applied to all ports and protocols as traffic passes through Zscaler's network, with Zscaler Internet Access and Zscaler Private Access covering web traffic and application access. Nothing it sells runs on an endpoint as a scanner, so the malware detection cycles in this index do not measure it. What it competes against is the other cloud-delivered platforms and the appliance firewalls it was designed to replace. Vendor page →
