CSF/LFD + Mod_Security = best combo.

Never tried APF, probably never will. lol.

Also ya you're right the GUI is nice & simple.
Sandino Reviewed by Sandino on . CSF or APF Firewall Alright so CSF & APF are pretty popular firewalls for linux around the hosting industry but which do you prefer your self ive been messing around with both have always preferred csf because of a GUI, but APF seems to work pretty nice as well. Please vote and state which you have chosen and the reason. Rating: 5
