Entrust UC Multi-Domain SSL

TLS/SSL Certificates

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.

Get powerful SSL-Based security for your UC-enabled communications environment

  • The defining feature of a UC SSL Certificate is the use of the SAN field in the certificate. In the SAN field any number of different domain names or common names. UC SSL Certificates are more cost efficient because they can secure external network names and be enabled to work on any included domain. For example, you could get one UC Multi-Domain SSL Certificate to cover:
  •  yourdomain.com
  •  mail.yourdomain.com
  •  autodiscover.yourdomain.com
  •  example.com
  •  dev.example2.com

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.
