Secure multiple domains
with a single certificate 

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: 

www.example.com 
www.example2.com 
www.example3.net 
mail.example.net
dev.example2.net 

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. 

DigiCert offers greater flexibility with every TLS/SSL certificate, including
multi-domain and wildcard options for nearly every certificate.
