Multi-Domain SSL

Secure up to 100 different domains, subdomains or IP addresses with only one SSL Certificate.

SSL for Exchange, Unified Communications & Hosting

  • Example Configuration

Multi-domain SSL Certificates from GlobalSign utilize Subject Alternative Names (SANs) to give you the flexibility to secure up to 100 different domain names, subdomains, and public IP addresses using only one SSL Certificate and using only one IP address.

GlobalSign has worked with Microsoft to develop an SSL Certificate specifically for use within the Exchange and Communications Server environments. A Multi-Domain SSL Certificate from GlobalSign allows you to deploy the Domain Security feature and enable secure client access from the Internet. Multi-Domain SSL was developed originally for Unified Communications applications, but can benefit anyone looking for simplicity of consolidating many domain names into a single SSL Certificate and single IP address.
