Palo Alto Networks PA-5500 Series Quantum Optimized Next-Generation Firewalls (NGFWs)—comprising the PA-5540, PA-5550, PA-5560, PA-5570, and PA-5580— are ideal for high-speed data center, internet gateway, and service provider deployments. This series provides visibility into and secures all traffic, including postquantum encrypted traffic. The operating system of the PA-5500 Series is PANOS, the same software that runs all Palo Alto Networks NGFWs.

PAN-OS natively classifies all traffic—including applications, threats, and content—and then ties that traffic to the user regardless of location or device type. The applications, content, and users that run your business serve as the basis of your security policies, resulting in an improved security posture and reduced incident response time. PAN-OS embeds machine learning (ML) in the core of the firewall to provide inline signatureless attack prevention for file-based attacks while identifying and immediately stopping never-before seen phishing attempts.

PA-5500 Series is a post-quantum cryptography-ready device that helps you achieve quantum-safe security in hardware and software with PAN-OS 12.1. PA-5500 Series NGFWs support:

• Post-quantum cryptography (PQC) for PQC SSL/TLS decryption, PQC VPN site-to-site, PQC SSL/ TLS Cipher Translation Proxy, and PQC SSL/TLS Service Profile for Management Access to the firewall.
• PQC algorithms, including NIST standards, like ML-KEM, ML-DSA, and SLH-DSA, as well as experimental PQCs, like Classic McEliece, BIKE, HQC, Frodo-KEM, and NTRU-Prime.
• A newly introduced PCIe slot for the future addition of post-quantum capabilities.
