FAQs
What's the difference between a multi-domain and a wildcard certificate?
Multi-domain certificates can secure up to 250 different SANs (exchange.yourdomainname.com, xchange.eurodns.com, lync.yourdomainname.com, etc.), while wildcard certificates work for an unlimited number of subdomains within the same primary domain.
How many wildcards are allowed?
A multi-domain certificate includes 3 SANs, which means the certificate bought protects up to 3 non-wildcard domains for the base price.
Additional SANs can be ordered with an extra cost. A wildcard option can be chosen for any additional SAN to protect an unlimited number of sub-domains.
Modern browsers ignore the common name for any multi-domain certificate; thus, we recommend for each domain or domain wildcard to specify it as SAN. Even if the common name is not listed as SAN, it will be automatically added and will count for one.
Example:
- CN: mydomain.com
- SAN1: mydomain.com
- SAN2: anotherdomain1.com
- SAN3: anotherdomain2.com
Can I really secure up to 250 domains?
Yes, our Multi-Domain SSL certificates can handle up to 250 different domains, sub-domains and IPs (SANs) on a single certificate.
How can I add more SANs to my Multi-domain certificate?
Additional SANs can be purchased as an option at the same time as the multi-domain certificate, or later by upgrading the quantity and performing a reissuance.
How expensive is it to add new SANs later?
The addition of new SANs to a Multi-Domain SSL certificate is charged on a prorated basis for the remaining time left on the certificate.
