I have now upgraded to Premium and it is well worth the money!
This is a must have plugin! I am amazed at the number of login attempts I see and the ease with which I can manage bad behavior!
The free version is really great but the paid version is down right amazing!
My initial review was titled:
Good but I can not say great ... yet
I can not give it the final star because my first experience showed it misses some stuff.
It caught 3 out of 38 injections on the first run on an infected site.
That said - the ability to see dif on changed files is awesome!
I love the IP logging and the ability to permanently block bad guys.
Easy to set up and run!
Price seems really reasonable.
I am on the very of getting a 10 site license but am a wee bit leary as response to support requests in the forums seems pretty backed up at the moment.
