Multi Domain SSL

What is a Multi-Domain Certificate?

Multi-Domain also referred commonly as SAN Certificates, utilize Subject Alternative
Names (SANs) to secure up to 100 different domain names, subdomains, and
public IP addresses, using only one SSL Certificate and requiring only one IP to host
the Certificate.

We worked with Microsoft to develop a SSL Certificate specifically for use within
the Exchange and Communications Server environments. A SAN SSL Certificate
allows you to deploy the Domain Security feature and enable secure client access
from the Internet

While Multi-Domain SSL was originally developed for Unified Communications
applications, it can benefit anyone looking for the simplicity of consolidating many
domain names into a single SSL Certificate and single IP address.
