Secure up to 25 domains on a single server With a True BusinessID Multi-Domain certificate, you can add, edit, or delete up to 25 domain names over the lifetime of the certificate. Designed for Microsoft Exchange 2007 or Microsoft Communications Servers, this Unified Communications Certificate is also ideal for shared hosting environments, QA testing environments, and small businesses with multiple business applications to secure on a single server.

Full authentication with flexible domain options. GeoTrust fully authenticates your organization and your primary domain to quickly issue your certificate. You can add, edit or delete any additional domain names to the subject alt name (SAN) field during the enrollment process or at anytime during the lifecycle of the certificate. True BusinessID Multi-Domain certificates support several domain formats as long as the organization specified in the certificate has the right to use the domain.
