A Subject Alternate Name (or SAN) certificate is a digital security certificate which allows multiple hostnames to be protected by a single certificate. A SAN certificate may also be called a Unified Communication Certificate (or UCC), a multi-domain certificate, or an Exchange certificate.

If you have a lot of hostnames pointing at the same service on the same server(s), then it's fine to use a wildcard certificate - so long as that wildcard certificate doesn't also cover hostnames pointing at other servers; otherwise, each service should have its own certificates.

How do server certificates work?

The web server sends the browser/server a copy of its SSL certificate. The browser/server checks to see whether or not it trusts the SSL certificate. The web server sends back a digitally signed acknowledgement to start an SSL encrypted session. Encrypted data is shared between the browser/server and the web server.
