mod_evasive in Plesk
Add mod evasive as module for Plesk
You can enable EPEL yum repository and install and configure mod_evasive for your Apache. But in latest Plesk Onyx versions it’s better and effective using ModSecurity Plesk feature for protecting attacks.
It would be a good thing to have it with plesk.
I think this module is essential along with mod_security

If you want to take security seriously in Plesk you must integrate all the tools which enable your customers to secure their subscribers. It's been almost three years since the initial request. We don't think it's so hard to integrate mod_evasive.
