That I can check if my website has been hacked or not? The price isn't bad but it could be more affordable for smaller companies that don’t have big budgets like us! There are some features in RBS which we're still waiting because they haven´ t released them yet (like an option where you see all vulnerabilities from different sources).
Also sometimes when scanning your own server i get false positive results so there might need improvements too :) We use this as our web security scanner at RedBrick Technologies since last 5 years now. It's one thing what most people want after having their site breached by hackers - finding out who did hack me/us first hand with his tools etc., And here comes RBSTools exactly doing just that :D.
