"It doesn't need to care about encryption, as it drills into the payload of every data packet and reassembles the content, thereby knowing what it is"

Since the first is unlikely, odds are you've been reading their marketing materials, which would tell you that the product cures world hunger if they believed you'd fall for it. I recently got a call from a guy promising that his DNS server software would ensure 100% uptime for my web server.
