Palo Alto PA-455 Next-Generation Firewall with ML Threat Prevention

Defend Your Branch with Precision AI-Driven Security

Mid-sized enterprises and distributed retail branches need more than basic filtering—they need intelligent defense. The Palo Alto Networks PA-455 delivers exactly that. As part of the PA-400 Series, it brings machine learning to the edge with inline zero-day threat prevention, deep visibility, and simplified management—all in a compact desktop or rack-mountable appliance.

Built to secure IoT-rich environments and remote users, the PA-455 combines SFP/RJ45 combo flexibility, PoE support, and SD-WAN readiness. It's ideal for organizations deploying high-performance, cloud-connected applications while minimizing risk and complexity.

Key Benefits & Features

ML-Powered Threat Detection and Prevention

Inline machine learning stops unknown malware and phishing attempts before they reach endpoints. Zero-delay updates, cloud-powered threat intel, and Precision AI™ ensure protection against even evasive attacks—without relying solely on signature-based methods.

High Performance with Predictable Throughput

With 3.6 Gbps firewall throughput and 2.3 Gbps threat prevention, the PA-455 ensures real-time scanning without bottlenecks—even with multiple security services enabled. Its 56,000 new sessions per second capability supports demanding environments.

Enterprise-Class Networking & SD-WAN Support

From L2/L3 and virtual wire modes to dynamic SD-WAN routing, this device offers advanced control across modern WAN infrastructures. BGP, OSPF, and multicast support ensure flexible deployments in distributed setups.

Flexible Port Configuration with Built-in PoE

Includes 2 SFP/RJ45 combo ports and 6 RJ45 ports, with 4 PoE-enabled ports supplying up to 91W power—ideal for access points and VoIP phones. Redundant power support enhances uptime in mission-critical sites.

Unified Management with Panorama & Strata Cloud

Manage thousands of firewalls centrally using Panorama® or the AI-powered Strata™ Cloud Manager. Enforce Zero Trust policies across hardware and cloud environments, with predictive analytics for capacity planning and real-time compliance checks.
