Instead of purchasing individual certificates for each domain name, you can secure up to 24 domains in one UC/SAN certificate which can save your cost and time to manage SSL certificates. The UC/SAN certificate is ideal for shared hosting or QA testing environments and small businesses with multiple business applications to secure on a single server.
For example: you can secure below domains in your UC/SAN certificate:
Fully Qualified domain name: yourcompany.com
Different subdomain name: mail.yourcompany.com
Different top level domain: yourcompany.net
Intranet and .local name: server.local
