Explanation
The Decryption Broker feature allows a Palo Alto Networks NGFW to act as a central SSL/TLS decryption point for third-party security tools. The firewall decrypts inbound or outbound SSL/TLS sessions, then forwards the plaintext traffic through a defined security chain - an ordered sequence of third-party inspection appliances (e.g., DLP, IDS, malware inspection tools) that cannot decrypt SSL themselves. After the chain completes inspection, the firewall re-encrypts the traffic and forwards it to its destination. This is not about forcing weaker ciphers, inspecting IPsec, or breaking unknown cipher suites - it is purely about enabling third-party tools to inspect decrypted HTTP traffic they otherwise couldn't see.
