What is reported in the Windows Security Centre is Microsoft-dependent, and only peripherally to do with the software vendor.
I have no idea of the hoops that have to be jumped through, but there is an involved procedure to go through for a software vendor to have a product qualify for registration in the WSC.
Some firewalls, for example, work good as gold, but are not recognised. (Kerio 2.15, for instance.)
Many antispywares are not listed at all. Ironically Windows Defender, a MS product, is listed, even though it isn't (reportedly) as effective as a lot of other 3rd party applications.
Go figure.
