Yea, agree with the above comments. This can all be done with Nessus (for free). What do you mean by `deep dive`? Are you reselling Burp? What do you plan to offer on the network security side? Keep in mind you should be targeting people who know nothing about security (you may want to play with the wording on your site). because experts already have a tool bag of tricks that can exceed these offerings for free.
We've written a lot of custom tools to do some heavier auditing of a website than off-the-shelf Nessus. With that said, we are definitely targeting those companies and teams that don't have the time or experience to be focused on setting up and running Nessus consistently.
Our SQLi and XSS modules in particular are quite a bit heavier than Nessus', but there are other features like page de-duplication that optimize speed as well.
True; wasn't saying Nessus is a good tool for web applications. Quite the opposite.
Burp Suite is great for anyone who knows what they're doing; for anyone that isn't already a security guy/gal the UI is near impossible to figure out, and the results aren't particularly actionable. That's much of what we try to fix.
Not trying to be argumentative, just clarifying! :)
