Centos 6 & above , RHEL 6 & above , Ubuntu 14 & above
Plesk 12.5 and above.
We know that Plesk has its own Firewall module, but something like APF/CSF will definitely make your life easier when it comes to firewall management.
Change log :
The interface saves scan reports for future reference. If you want to save space and not have to manually delete the scan reports, you can enable Log Retention and specify custom values of the number of reports you want to retain.
We are back as promised with another extension for Plesk. This time, it is a GUI to manage the APF/CSF firewall from inside Plesk, the Firewall Interface Extension.
