Excelent plugin, PRO version is a must

This plugin is already good in the free version, probaly enought for simple sites, but if you take security seriously, the PRO version is totaly another level.
I admit perhaps is not super easy to setup for newbies, but if you take some time to understand all is logic, it completely hides all your site, including paths, class names at css/html code, etc etc.
About the support, for the experience i had so far i just have good things to say.
