AFAIK neither Microsoft nor the ISC-squared (parent organization for the CISSP) seeks out practice test and/or elearning companies to solicit their input and opinion on exam objectives and cert program development, and so forth. I'd be very wary about the company's claims, and do lots of shopping around before giving anybody my business, particularly because of the wide availability of lots of cheap and medium-priced prep options for all the exams involved. Good luck in prepping for these certs!
