Hi, 

As I had tons of modsecurity rejects on various scanners I had to act. 

Didn't found a simple way to ban those requests thru CSF as CSF modsecurity module is not working. 

What I did is fully synchronized module that scans CSF tables, bans IP for 2 hours after X occurances in error_log and then unban without unbanning permament csf bans. What do You think is it a good solution? Should that not be an option in cPanel ... i just wonder

  Hey there!  If you ever think something should be an option inside cPanel you can always submit a feature request over at features.cpanel.net using the "Submit" button in the top right.  I make sure those get reviewed every two weeks with our product teams.
