Comodo (now Sectigo) Multi-Domain SSL certificates secure from 3 to 100 domain names and/or subdomains (seats).
The default price includes three seats. The additional seats require additional payment. The price for the seats ("Additional Domains") can be checked on the page with the details of the particular certificate.
It is possible to order more domains for the certificate after its purchase, please refer to this guide.
Note: Please keep in mind that the validity
period and the price for the additional SAN (Subject Alternative Name,
additional domain in the Multi-Domain certificate), ordered
after the certificate purchase will not be pro-rated.
This means that:
- The SAN, added to the Multi-Domain certificate any time after its purchase, will cost the same price as the SAN ordered along with the Multi-Domain certificate during the initial purchase;
- The SAN will expire together with the certificate it is attached to regardless of the exact date of SAN's purchase.
Note: www and non-www versions of one website are considered
as two different hostnames, so if you would like to secure both www and
non-www versions of one website, it will be necessary to specify both of
them on the different seats during certificate activation.
