Thanks for all the great feedback guys, im gonna the switch over from ithemes to Wordfence today. hope all goes well.
when i tested word fence out and read about its features i thought to myself, all honesty iThemes is little more than a limit login attempt that doesn't actually work (for me) very well. and really doesn't do much more than block users from visiting your site based on certain conditions, that and detect file changes, which is ok. but scanning for viruses is what i'd expect in a security package for any software.
And so im psyched to get Wordfence up and running and utilising the crowd sourced anti-virus and malware protection. very cool.
