Multi domain SSL certificate
A multi-domain SSL certificate can protect multiple domain names (Subject Alternative Name), so it is also known as SAN SSL, or UCC SSL certificate. The multi-domain certificate supports adding multiple different main domain names or sub-domains, which is far more cost-effective than applying for an SSL certificate for each domain name separately. It also simplifies the verification process and facilitates certificate management and renewal. At the same time, the multi-domain certificate is also the recommended certificate for the mail server (Exchange Server) encryption application.

Multi domain SSL certificate - Frequently Asked Questions
High flexibility: One SAN SSL certificate can protect multiple domain names and subdomains, and you can add up to 250 domain names within the validity period of a multi-domain certificate.
Cost-effective: Buying an SSL certificate for each domain name individually not only costs more, but also requires professionals to spend a lot of time and effort managing the certificate. A multi-domain SSL certificate protects all different domains with one SSL certificate while eliminating these high costs. In addition, because IT administrators only need to manage one certificate, the number of certificate renewals and the risk of expiration is reduced.
Common multi-domain SSL certificates protect 2-3 domain names by default, and can protect up to 250 domain names. The protected domain name can be the main domain name or the sub-domain name, and the domain names can be unrelated. For example: the following multiple different domain names
- www.iid.hk
- my.iid.hk
- www.baidu.com
- google.com
If you need to protect multiple domains, both multi-domain certificates and wildcard certificates are available. Ruicheng recommends choosing according to your budget and the specific number of domain names.
When you have multiple different domain names, such as 3 domain names, it is recommended to choose a multi-domain SSL certificate. If you need to add a new domain name, you can add a protected domain name for an additional fee.
When you have multiple subdomains at the same level, it is recommended to prefer a wildcard SSL certificate, because a wildcard certificate can protect unlimited subdomains, and there is no additional charge for new subdomains.
The multi-domain wildcard SSL certificate is an SSL certificate that combines the advantages of wildcard SSL and multi-domain SSL certificates. Use a multi-domain wildcard SSL certificate to protect multiple different domains and their unlimited number of sub-domains.
Therefore, when an enterprise entity has multiple different domain names and sub-domains, it is recommended to choose a multi-domain wildcard certificate, which saves time and money. For example: a multi-domain wildcard certificate can protect *.iid.hk;
*.shop.rubicfore.com; *.ssltrus.cn, etc.
