Save time and money by securing multiple domains on a single certificate
A single Comodo UC Certificate can offer protection to multiple domains and hosts configured in your Exchange Server where a traditional certificate or wildcard cannot. SSL certificates are limited to a single domain and wildcards can support all first level sub-domains of a single domain, e.g. *.example .com.
A Comodo UC certificate can protect completely different domains, for example www.example.com, www.example.net, www.example2.com and mail.example2.com. You can even secure multiple wildcard domains on a Comodo UCC
Simple, Economical Certificate Management
A single certificate supporting several domains, hosts and server applications simplifies your certificate management and is more economical than purchasing individual certificates for each domain.
