Multi-Domain SSL Certificates (sometimes referred to as SAN/UCC certificates) enable a single certificate to secure multiple domain names.
By taking advantage of TLS Subject Alternate Names (SANs), Multi-Domain Certificates provide a convenient option for organizations seeking to secure multiple domain names without the need to manage multiple certificates. Unlike wildcard certificates, multi-domain certificates can secure any mix of valid external domains even if they’re unrelated to each other.
Unified Communications Certificates (UCC) are TLS/SSL certificates intended specifically for the Microsoft Exchange and/or Microsoft Office Communication Server (OCS) environments. Also referred to as Exchange certificates, these multi-domain certificates use Subject Alternate Name (SAN) fields to secure the full set of addresses required to operate these Microsoft email servers.
