Explanation

SAN (Subject Alternative Name) is an extension to SSL/TLS certificates that allows a single certificate to secure multiple domain names. This method is ideal for situations where you want to secure several domains or subdomains with one certificate, reducing the complexity and number of certificates needed. SAN certificates are commonly used to support multiple domain names under a single SSL certificate, making them the best choice for the given scenario.
