SSL Certificates

Subject Alternative Name (SAN)

SSL Certificates normally secure only one Fully Qualified Domain Name (FQDN). The Subject Alternative Name (SAN) certificate however, secures several domain or server names.

A SAN SSL certificate gives you the opportunity to secure dozens of domain or server names with only one and the same SAN certificate. Don't mistake it with a Wildcard SSL certificate, which secures unlimited sub domain names underneath one domain name at only one level.

The SAN SSL certificate is especially used for Unified Communications (UC) like Microsoft Exchange and Microsoft Office Communications Server 2007.

Advantage

  •   Unlimited sub domain names can be secured by using one SSL certificate

Disadvantage

  • Changes have effect on all domains

Do you want a SSL certificate for two or more domain names?
