Multi-Domain UCC (SAN) SSL Certificates

A Multi-Domain SSL certificate, also known as a UCC, Unified Communications, or SAN certificate, is a type of certificate that uses Subject Alternative Names to secure multiple host names. Any number of different domain names can be included in the SAN field of the certificate enabling the certificate to work on any of the included domain names. For example, you could get one UC SSL Certificate to cover all of the following:

  • mydomain.com
  • mail.mydomain.com
  • autodiscover.mydomain.com
  • anotherdomain.com

This can provide significant cost savings in many situations. A UCC Certificate is also required for certain features in Microsoft's Exchange Server, Office Communications Server, and Live Communications Server. Here is a comparison of the cheapest UCC SSL Certificates offered. To compare more Multi-Domain SSL Certificates, use the SSL Advanced Search.
