Multi-domain SSL certificate

An ordinary SSL certificate contains only one domain name. The multi-domain SSL certificate contains multiple domain names (Subject Alternative Name) in one certificate, which can protect multiple different domain names. A multi-domain SSL certificate includes at least 2 domain names and can support up to 250 domain names.

Just purchase a multi-domain certificate, you can easily protect multiple domain names.
