DigiCert® Multi-domain TLS/SSL Certificates
One certificate for
every domain
Convert any DigiCert certificate to
encrypt up to 250 domains. That’s
digital trust for the real world.
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.
How to buy:
1. Select a certificate: Secure Site Pro, Secure Site or DigiCert Basic
2. Choose your coverage length
3. Multi-Domain: Enter any Subject Alternative Names (SANS) you want secured*
4. Checkout
* Price will be based on number of SANS entered.
DigiCert offers greater flexibility with every TLS/SSL certificate, including
multi-domain and wildcard options for nearly every certificate.
