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.
Secure Microsoft Exchange and Office Communications Server. SAN Certificates provide ideal support for your owa, mail, and autodiscover domains, plus they are included in the base price!
Secure different domains, such as abc.com, xyz.com, 123.com, or different top level domains such as domain.com, domain.net, domain.co.uk.
Secure all subdomains, even different level subdomains such
as www.domain.com, xxx.yyy.domain.com.
All levels are supported.
