The Problem

Traditional firewalls weren't built to secure modern traffic

of workloads will run in the cloud by 2028 (Gartner)
of web traffic is encrypted (Google)
of threats are delivered over encrypted channels (ThreatLabz)

Traditional firewalls can’t deliver zero trust

Traditional network-based firewalls use an IP-centric, zone-based architecture that increases the attack surface and lets threats move laterally. They can’t adapt to enforce dynamic policies based on user context, risk, and device posture. Next-generation firewalls (NGFWs), on-premises or in the cloud, struggle to inspect 100% of traffic without slowing performance, forcing network admins to choose between performance and security. 

In short, traditional and next-generation firewalls can't provide zero trust to protect work-from-anywhere users, cloud apps, and locations. 

Solution Overview

Move beyond legacy architecture with a zero trust firewall

Built on a cloud native platform, a zero trust firewall protects web and non-web traffic for all users, apps, locations, and clouds.

Unlimited scale and cloud native TLS/SSL decryption capabilities ensure 100% inspection of all traffic, with zero performance degradation. Protect users, devices, and apps anywhere from cyberthreats, protect data, and ensure regulatory compliance.
