The PA-5550 is a workhorse for the most demanding network edge, delivering speed, resilience, and future-proof security features to protect your critical infrastructure.
Extreme Throughput with AI-Powered Threat Prevention
Achieve enterprise-grade protection without sacrificing speed. The PA-5550 delivers a powerful 175 Gbps of firewall throughput and a formidable 120 Gbps of Threat Prevention throughput. This performance is backed by Precision AI, an embedded engine that prevents threats—including zero-day exploits and never-before-seen phishing attempts—in real time.
Quantum-Ready Cryptographic Protection and DC Power
Future-proof your network with the world's first quantum-optimized NGFW. The PA-5550 is post-quantum cryptography (PQC) ready, supporting PQC SSL/TLS decryption and PQC VPN site-to-site using NIST standards like ML-KEM. Designed for mission-critical deployments, the DC model supports robust -40 VDC to -60 VDC input power and features 2+2 redundant power supplies for maximum uptime and carrier-grade reliability.
Scalability and High Availability for the Core
Handle explosive traffic growth with support for up to 49M concurrent sessions and 1.67M new sessions per second. The PA-5550 features an extensive I/O array, including 4x 100G/400G QSFP-DD ports, and supports NGFW clustering with an active/active data plane for efficient horizontal scaling and a highly resilient solution.
