I like Foofus's approach.  I've been involved with far too many audits and assessments (from both sides), where this 
technical approach to foiling or fooling the auditor ends up blowing up in your face.

If you're concerned about the tools that are used, sit down with the testing company and ask them.  They should tell 
you.

Are you concerned that the testing company is using only one tool?  Tools like this are only as good as the person who 
uses them.  Do the testers understand the NASL scripts?  Have they written their own custom scripts?  If so, have any 
of these scripts been released back to the community (so that you can verify it)?  Having a clueless operator run ISS 
and Nessus, rather than just one, really doesn't give you much.
