How are GeoTrust and Equifax related?

GeoTrust was founded years ago by a few key people from Equifax Secure. In 2001 GeoTrust acquired Equifax Secure, which included the Equifax root certificates. Then in September of 2006 GeoTrust was acquired by VeriSign. Now, GeoTrust has become the world's second largest SSL provider.
