Great product & service

We got the certificate in less than a day! The whole process from enquiry to issuance was super quick. They even answered any question when it came to implementation. Everytime we had a query (big or small), the efficient DigiCert team was there for us. Impressed by their quick response time and resolving any issue. Great going DigiCert's customer service team!!

Excellent service above and beyond what I expected

Bryan P worked with us to ensure a transition of one SSL certificate for Horizon View behind an F5 Load Balancer went smoothly. He stayed on the line and helped us troubleshoot all the various issues that cropped up. I highly recommend Digicert based on the experience of their support.
