Quick resolution of my circumstance

DigiCert got me up and going in a very short period despite the fact that the whois information for my site was incorrect.
5 out of 5 stars.

Best Customer Service around!

I love calling that number at the top of the website and somebody just answers the line. No automated garbage! I've called a couple times and every person I spoke with was very knowledgeable. Prices are competitive and service is far beyond expectation. Also, the interface is very clean and easy. Digicert is the way to go!
5 out of 5 stars.

Fast service and flexible product

To make our choice we contacted 5 major Wildcard providers (selecting only the ones that were SHA2 compliant) with questions. Out of the 5 only 2 replied, Digicert within 15 minutes and the other after 6 hours. Digicert was also the most flexible to combine wildcards with additional domains. Many online reviews were rating Digicert at the top and so far they were right!
