This plugin is well thought out and quite extensive. Deserves the "All in One" designation. I especially like the cookie-based deflector that was just added in the latest update.
What the "cookie" does is deflect any brute force attacks to any page you specify if the browser doesn't provide a cookie or add a special token on the page request. The brute force attackers have no way to grab that cookie, so you can breath easier knowing your site can be attacked until the cows come home, but very, very little of your machine bandwidth and resources will be consumed.
I made this suggestion in their support forum and they rolled it out in just a few days. Bravo!
