Applications Filtering - An Overview
Previous Topic  Next Topic 

Applications filtering in Firewall Plus allows you to control which applications installed on your computer have access to the Internet or a network, and define the permissions for each application.

By default, Firewall Plus will allow a list of "known applications" as defined by PC Tools to connect to the Internet/Network. If an "unknown application" attempts to access the Internet, or a network, Firewall Plus will display a pop-up notification that will let you choose whether you want to allow or block the application from connecting.

Full access : grants full connectivity

Block Access : denies access

You can further distinguish permissions for listening and connecting events:

Information about adding/deleting applications and assigning permissions is explained in detail here.
