Very helpful after a compromised server

I had every WordPress site on an old server get hacked. I had never heard of this plugin before, but came across it from a Google search. I loaded it onto each of the sites on my server, and was able to have the sites all clean within an hour or so. I was able to actually see failed login attempts from the hacker as I was restricting access using the plugin.

Happy to add this one to my toolbox of regularly used plugins, and definitely recommend it.
