And we are back as promised with another extension for Parallels Plesk. This time, it is a GUI to manage the APF firewall from inside Parallels Plesk, the A-AST APF Parallels Plesk Extension / Module. We know that Plesk has its own Firewall module, but something like APF will definitely make your life easier when it comes to firewall management. Every Install of our Plugin will load a custom ruleset to your firewall that you can manage from inside your Plesk Panel.
