High-Throughput, AI-Ready Protection for Core and Edge

The Palo Alto Networks PA-5550 secures high-speed data centers and internet gateways with ML-powered threat prevention and post-quantum readiness. Built on the PA-5500 Series architecture, it delivers predictable performance with single-pass processing and Precision AI to analyze and stop threats in real time.

Key Benefits & Features

The PA-5550 brings deep visibility, Layer 7 control, and inline prevention to environments that demand scale and resiliency. It supports post-quantum cryptography options, advanced URL and DNS defenses, and NGFW clustering for high availability.

Proven Performance at Scale

Handle growth confidently with 175 Gbps firewall throughput (appmix, 120 Gbps threat prevention, 100 Gbps IPsec VPN, 49 million concurrent sessions, and 1.67 million new sessions per second. These figures enable large east-west and north-south inspection without bottlenecks.

AI-Driven Prevention and L7 Visibility

Inline machine learning and App-ID provide accurate application identification and signatureless prevention against zero-day malware and phishing. Policies are enforced by user and application for precise control, improving security posture while reducing incident response time.

Post-Quantum Readiness

Prepare for future cryptographic shifts with support for PQC use cases across SSL/TLS inspection and VPN, including NIST algorithms such as ML-KEM and ML-DSA.

Operational Consistency and HA

Manage at scale through Strata Cloud Manager with AI-assisted insights, and deploy NGFW clustering for active-active scale and redundancy. The series also supports traditional HA.

Ideal Use Cases

• Data centers and internet edges that need high throughput with deep inspection.
• Service providers requiring large session capacity and resilient clustering.
• Enterprises consolidating security with AI-powered visibility and user-based policy.
