What is a Multi-Domain (SAN) Certificate?

Multi-Domain Certificates, also called SAN certificates, offer complete control over the Subject Alternative Name field. These certificates are ideal for securing multiple names across different domains and subdomains (e.g., Exchange/OCS environments). You also have the option to add, change, and delete any of the SANs on the fly to reflect the evolving needs of your network.

With just one Multi-Domain (SAN) Certificate, you could secure the following domains:

Reduce Complexities of Server Configurations

Run multiple services on one IP address and use a multi-domain (SAN) certificate to secure:

OWA
SMTP
Autodiscovery
ActiveSync
Outlook
Anywhere

Increase Trust with EV Multi-Domain Certificates

If you want to boost user confidence and gain the branded green bar URL, then you need a DigiCert Extended Validation Multi-Domain Certificate. Convenient and cost-effective, it will provide the same flexibility of a multi-domain (SAN) certificate with the added visual benefits of Extended Validation.

Use Wildcards in a Multi-Domain Certificate

Security requirements vary greatly from network to network. As a result, you may require a Multi-Domain Certificate with Wildcard capabilities. We can accommodate this by making your SAN compatible with the asterisk (*) convention of Wildcards. This gives you more flexibility and simplifies management.

Loyal customer disappointment

For a customer that is with Digicert for so many years now, on renewal of certificates, starting the verification process all over again and sending all documents again and again is non sense!

Good service some employees need a bit of tech coaching

Called 5 times. The last two employees understood my scenario ( domain ssl certificate needed to federate a DC with Azure AD ) and helped me go through the process. The first three guys were trying to see how to get out of the situation. My name is Yordan Radkov and you can contact me for reference 😉

P.S. Turns out you dont have to provide passport data and phone bill. In my case i put my phone number in the index.html file of my IIS server running in my domain. That was good enough proof.
