Securing Unified Communications got a bit easier with Comodo's Unified Communication Multiple Domain Wildcard SSL certificate. This certificate is a perfect blend of all the benefits of a Unified Communication certificate and a wildcard SSL certificate. Designed for Microsoft Exchange and Office Communications infrastructures, this feature-rich UC wildcard SSL certificate efficiently secures multiple domains and unlimited sub-domains under just one certificate! It is an Organization Validated (OV) certificate with 99.3% browser and mobile compatibility.
PLEASE NOTE: A non-wildcard domain (e.g. www.yourdomain.com) must be listed as the Common Name, or base domain in the CSR. This certificate will secure 2 wildcard domains (e.g. *.yourdomain.com, *.domain.com, etc.) by default. You must purchase additional SAN support if you need to secure more than 2 wildcard or non-wildcard domains.
