Decryption Broker on a Next-Generation Firewall (NGFW) provides two primary benefits:

Offloading SSL decryption: The NGFW decrypts traffic once and then forwards it to multiple security devices for inspection, avoiding the need to decrypt and re-encrypt traffic multiple times, thus improving efficiency.

Reducing third-party devices: By handling SSL decryption within the NGFW, the need for separate, dedicated SSL decryption devices is eliminated, reducing the complexity and number of devices required for network security.

These features streamline traffic analysis and enforcement while maintaining robust security.

The customer currently lacks visibility into the Layer 7 application traffic on port 53, which is typically used for DNS. Palo Alto Networks' App-ID technology can identify applications traversing the network irrespective of the port, protocol, or encryption (SSL or SSH). By using App-ID, the customer can gain visibility into the specific applications being used, even if they are running over standard ports such as 53. This capability not only identifies the applications but also allows for granular control over them, enabling the customer to block unsanctioned applications if necessary.

When configuring the NGFW to act as a decryption broker for multiple transparent bridge security chains, the following items are required:

A unique Transparent Bridge Decryption Forwarding Profile to a single Decryption policy rule (B): Each decryption policy rule must be associated with a unique Transparent Bridge Decryption Forwarding Profile. This ensures that decrypted traffic is forwarded appropriately to the specific security chain.

A unique Decryption policy rule is required per security chain (C): You need to create a separate decryption policy rule for each security chain. This allows you to distribute the decrypted traffic among multiple security chains based on policy criteria.

These configurations enable the firewall to effectively manage and distribute the load across multiple security chains, ensuring optimal performance and security​ (Palo Alto Networks)​​ (Palo Alto Networks)
