DigiCert® Multi-Domain
TLS/SSL Certificates

Secure multiple domains
with a single certificate

Now every DigiCert certificate allows you
to add multi-domain SANs at checkout—
up to 250 domains.

What is a Multi-Domain Certificate?

Multi-Domain Certificates, also called SAN certificates, offer boundless flexibility and complete control over the Subject Alternative Name field. And now, any DigiCert certificate can be configured to allow multi-domain. These certificates are ideal for securing many 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. Here’s how it works: 


With any DigiCert certificate, you could secure the following domains: 



The  Subject Alternative Name field lets you specify additional host names (sites, IP addresses, common names, etc.) to be protected by a single TLS/SSL certificate, such as a Multi-Domain (SAN) or Extended Validation Multi-Domain Certificate.
