Entrust UC Multi-Domain SSL Certificates have been developed primarily for use with Exchange, Lync, or Skype for Business Servers or environments where you need to secure multiple names across different domains. Our UC Multi-Domain SSL Certificates use Subject Alternative Names (SANs) to secure 250 domains, websites or subdomains with one certificate.
To use the Domain Security feature in a UC SSL Certificate, Microsoft works with public X.509 certification authorities (CAs) to enable secure client access from the Internet to Exchange, Lync and Skype for Business servers. A UC SSL Certificate from Entrust allows you to deploy the Domain Security feature and enable secure client access from the Internet. While developed for Unified Communications applications, Multi-Domain SSL can benefit anyone looking for simplicity of consolidating many domain names into a single SSL Certificate and single IP address.
When you buy an Unified Communications SSL Certificate you can add additional domains using the Subject Alternative Name (SAN) extension. Before you attempt to complete the online certificate enrollment process, take a look at the SSL Enrollment guide. Enrolling is faster and easier if you have collected the information you need before beginning the enrollment process..
