What is a “single-root” SSL certificate and are GeoTrust SSL certificates chained?

All GeoTrust certificates are single root certificates. GeoTrust is a spinoff of Equifax Secure. In 2001, GeoTrust acquired Equifax Secure, which included the Equifax root certificates. Unlike other companies which issue certificates off chained roots or license roots from third parties like GoDaddy, Comodo or Network Solutions, GeoTrust owns the root and is not dependent on another root provider. Chained certificates tend to be seen on the low end of the SSL market and require more installation assistance than a single root cert. Plus not all browsers today support chained SSL certificates so the ubquity is lower.
