With a GeoTrust® True BusinessID Multi-Domain certificate, you can add, edit, or
delete up to 25 domain names over the lifetime of the certificate. Multi domain
SSL requires CSR key only for the primary domain name and no more CSR key for other
private or public domain names, private server names, or IP address. Designed for
Microsoft Exchange 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.
