The Problem

Traditional firewalls weren't built to secure modern traffic

70%
of workloads will run in the cloud by 2028 (Gartner)
95%
of web traffic is encrypted (Google)
85.9%
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.
