To avoid split-brain scenarios in an active/passive high availability (HA) pair deployment, it is essential to ensure reliable communication between the HA peers. Using the management interface as the HA1 backup link provides an additional communication path between the firewalls, ensuring they can synchronize state information and avoid scenarios where both units assume the active role due to a communication failure.

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.
