Firewall

Secure, adaptive protection for web and non-web traffic. All users and devices, all ports and protocols, all the time.

Zscaler Firewall safeguards web and non-web traffic for all users, applications, and locations with the industry’s most comprehensive cloud native zero trust platform.

Why Firewall-as-a-Service (FWaaS)

Only a cloud-delivered firewall can deliver zero trust

Firewalls and VPNs valiantly protected networks and users when the perimeter was well-defined. But in today’s cloud- and mobile-first world—where nearly all internet traffic is encrypted—network-centric security cannot dynamically adapt and enforce policies based user context and risk and device posture. Simply, traditional and next-generation firewalls fall short at protecting work-from-anywhere users, cloud apps, and distributed data.
