What is Multi-Domain/UCC SSL Certificate?
Multi-Domain Certificates, also called SAN (Subject Alternate Names) Certificates, UCC (Unified Communication Certificate). It's used to secure multiple domains with a single certificate. It's ideal for securing many names across different domains and subdomains.
This certificate offers flexibility and complete control over the Subject Alternative Name field. The Subject Alternative Name field lets you specify additional host names to be protected by a single SSL/TLS certificate.
