The PA-5000 Series of enterprise firewalls is designed to protect data centers, large enterprise Internet gateways, and service provider environments where traffic demands dictate predictable firewall and threat prevention throughput. Traffic flows of up to 20 Gbps are effectively protected with more than 40 processors distributed across four functional areas: networking, security, content inspection and management.

Reliability and resiliency is delivered by active/active or active/passive high availability; physical separation of data and control plane; and redundant, hot swappable components.
