Firewall Application Rules

This Article Applies to:

  • AVG Business Cloud Console


Application Rules are specifically meant to control the access for various applications that may run on your devices. You can choose whether connections for applications with no defined rules are auto-decided by the Firewall, chosen by the user, or allowed/disallowed in the drop-down menu. We recommend you ensure these rules are controlled by your console for maximum security across your network.

Default Application Rules

Each policy contains default application rules to allow common applications to communicate properly. You can modify or delete these rules as you wish in order to change how the listed application communicates.

When making configuration changes, pay attention to the application path listed in the default rule. The path defined in the console should match the path on the client side.
