Why upgrade from PA-500 to PA-440
The PA-440 addresses the performance and operational limitations of the PA-500 with a modern architecture that delivers significantly higher throughput and faster management operations.
12x throughput increase
The PA-500 maxes out at 250 Mbps of firewall throughput. The PA-440 delivers 3.0 Gbps, enabling full utilization of modern gigabit connections.
Instant management commits
PA-500 management commit times could exceed 20 minutes. The PA-440 quad-core processor reduces commits to seconds.
9x threat prevention gain
The PA-500 provides 100 Mbps threat prevention. The PA-440 delivers 900 Mbps, inspecting encrypted traffic without performance impact.
Fanless silent design
The PA-440 maintains a fanless desktop form factor, suitable for branch offices, retail, and healthcare environments.
