Is Corellium a Good Tool for Vulnerabilty Research?

Corellium is also a very powerful tool use for vulnerabilty research. How do you keep it out of the hands of not only bad guys, but financially motivated malwer? We try to develop a report with all the companies that we sell to, so that we intimately understand what, what their intentions are. And i don't imagine there's a fool proof way of saying, this customer will never use this maliciously, or whatever.
