After months of using the free version I was more than happy with the protection on my main site. Now I have the premium version and it has helped me tremendously. The live view helped me pinpoint files that were suspiciously being viewed constantly. Certain countries were a big problem for me so I bought the premium version to block by country. Still tweaking the settings but so far I have eliminated 80% of issues.
If you really want to protect your site I recommend this plugin
