You probably want to be careful about how you word "we've added HackerSafe" to corporate customers. I will say the following things:
* "Off-the-shelf" scanner-based certifications are not held in uniformly high esteem by companies with IT security groups.
* HackerSafe just won the Pwnie award at Black Hat for "Lamest Vendor Response".
* Talking about how you have a security SDLC, code reviews, and secure architecture will offer much bigger warm fuzzies to customers.
Also, avoid blanket statements like "so the data is secure". Marketing 101. If you're going to invite objections, make sure they're objections you want to deal with, not ones where you'll eventually have to concede.
