Is there nobody else other than the four listed at ?

I am not looking for a buying recommendation, just alternatives.

Sorry, Joe, GlobalSign is already among the four listed, and Avocosecure is an Office 2003 add-on. Avocosecure mimics but doesn't use Office 2007's Digital ID feature. Do you know any more? – William C Dec 1 '10 at 14:06
Sorry completely missed Globalsign on that list. No others that I know of sorry although I bet Google knows more than me. :-) – Joe Taylor Dec 1 '10 at 15:43
