Simple and Professional SSL Certificate

The certificate process was simple and straight forward. It came through quickly so we could update our website domain right away and also upload the Certificate to our mail servers. It was easy and their support team was the best, very helpful and knowledgeable which is a nice thing to experience when doing these things.

5 out of 5 stars.

Incredibly Quick, Great Service!

We didn't know our Exchange certificate was expired until it was expired. We had another provider for our SSL certificates, and they were estimating 3 days to provide us a replacement certificate for their "quick certificate". DigiCert was able not only provide us with a new certificate, but the support was fantastic even at midnight. I'll never go with another SSL certificate provider! Quick, professional, very courteous. I highly recommend this service.
