By default, a PAN-DB server uses predefined certificates for mutual authentication to establish
the SSL connections used for management access and interdevice communication.
However, you can configure authentication using custom certificates instead. Custom
certificates allow you to establish a unique chain of trust to ensure mutual
authentication between your PAN-DB server and firewalls. In the case of a PAN-DB
private cloud, the firewall acts as the client and the PAN-DB server acts as the
server.
