Unified Communications

Designed exclusively for Microsoft Exchange and Office Communications infrastructures, Comodo's Unified Communications Certificates allow a single certificate to provide SSL-secured communications for multiple domains and multiple host names operating on a single IP address.

Provide SSL Support for different domains as such - not merely sub-domains
A single Comodo UC Certificate can offer protection to multiple domains and hosts configured in your Exchange Server where a traditional or a wildcard SSL certificate cannot. Traditional SSL certificates are limited to a single domain and a wildcard certificate can support all the first level sub-domains of a single domain, e.g. *.example .com. A Comodo UC certificate can protect different domains as such, e.g. www.example.com, www. example.net etc.

Simplifies Certificate Management and is Economical
A single certificate supporting several domains, hosts and server applications simplifies your certificate management and proves economical, against implementing individual certificates for each domain.

Subject Alternative Name (SAN) control
SAN field control lets you adjust the domains listed in the certificate

Highest Levels of Security
Comodo Unified Communication Certificates support 256 bit encryption levels and are signed with 2048 bit signatures - in compliance with US Government's National Institute for Standards and Technology's post recommendations for SSL root key strength.
