Multi-domain SSL certificates (SAN)

What is the difference between a multi-domain SAN certificate and a wildcard certificate with protection of subdomains

A multi-domain SAN certificate protects multiple independent domain names. For example, one such certificate can be used for domains: example.com, eg.net, etc.

Unlike SAN, wildcard certificates protect only one unique domain, but additionally all its subdomains. For example, you can install it on the example.com domain itself and on any of its subdomains, such as admin.example.com, user.example.com.

Why do I need a multi-domain certificate?

A multi-domain SSL certificate is advantageous for large projects to make website and service management easier.

Saves time

A multi-domain SAN certificate makes domain administration easier. You only need to install an SSL certificate once and it will be valid for all domain names. When the time comes to renew, you will not have to pay separately for a certificate for each domain.

Handling SSL certificates is even easier with ISPmanager - it takes just a couple of clicks to install them.

Convenient for growing projects

You can connect new domains to an already installed multi-domain certificate. For example, a company bought an SSL certificate with protection for 10 domains and used three of them for online stores. There are seven more domains in reserve. After a few months, the business grew, and new websites appeared. They can be protected by re-issuing certificates. No extra charge will be needed.
