Multi-Domain Certificate

A Multi-Domain Certificate (MDC) is a type of SSL/TLS certificate that secures multiple domain names and subdomains under a single certificate. It allows organizations to protect several websites or services with one certificate, simplifying management and reducing costs compared to individual certificates for each domain. These certificates are commonly used for securing web applications, APIs, and email servers across different domains.

Also known as: SAN Certificate, UCC Certificate, Multi-SAN Certificate, Unified Communications Certificate, MDC
