Explanation

A Subject Alternative Name (SAN) certificate lets you bundle multiple distinct hostnames, including across different domains, in a single TLS certificate. With one SAN cert you can list: wiki.mycompany.org campus.mycompany.com This keeps costs down (versus buying four separate certs) and avoids the domain restriction of a single wildcard, while still providing proper end-to-end HTTPS protection so that any interception triggers a browser warning and alerts users to on-path attacks.
