No Exploit Defense?

I got this in the mail today. It’s a sales video from WP Site Guardian. They claim that Wordfence and other popular security plugins don’t protect against exploit attacks. The video shows them hacking a site in seconds. No doubt, it’s a sales ploy, but I would like a Wordfence response to it — also, I think you should know they are defaming your company in this video: http://wpsiteguardian.com/live2.php
