There is also a public directory though. I don't know how many CISSPs actually opt-in for it though; I don't. Here's a link to the public directory: https://webportal.isc2.org/BuyersGuide/ProfessionalSearch.aspx
I will check out isc2.org again. I checked there briefly but didn't find a listing from the sections I looked at. I am looking for someone in particular that I work with as I am just not 100% sure that they would have been able to pass the cissp.
