We have been recommended using CSF - http://configserver.com/cp/csf.html
- to help secure our dedicated server. We would like to go ahead and install it, but first would like to find out: 1) if there are any existing firewalls installed on the server by default and 2) if there is anything we should be aware of before installing it. (would like to avoid any down-time).
It would be great to get some feedback on this from anyone who is running CSF on a afrihost server!
