COMODO EXTENDS UC CERTIFICATE ( UNIFIED COMMUNICATIONS CERTIFICATE ) OFFERING TO THREE YEARS

Built for Microsoft Exchange 2007 and Office Communications Server 2007, 3-year Unified Communications Certificates reduce certificate cost and administrative overhead.

Jersey City, NJ, November 12, 2008 — Comodo a leading Internet trust and security company today announced the availability of three (3) year term Unified Communications (UC) Certificates. These digital certificates support Microsoft Exchange and Office Communications Server 2007 networks, and provide high visibility, recognition and security for unified communications and business email services.

Greater Flexibility, Economy and SSL Security for Microsoft Exchange 2007 and/or Office Communications Server 2007 networks.

UC Certificates make Microsoft Exchange and Office Communication Server 2007 implementations and administration easier and more flexible than ever before. Built for Microsoft Exchange 2007 and Office Communications Server 2007, Comodo’s multi-year UC Certificates are designed to allow customers to access the features of these new applications, making extensive use of SSL certificates supporting the Subject Alternative Name (SAN) field. UCCs enable administrative flexibility to secure client-server and server-server communications while supporting multiple Exchange and Office Communications 2007 services (e.g. Outlook Web Access, SMTP-TLS, Auto-Discovery, ActiveSync and Outlook Anywhere) – all with a single UC Certificate. For example, while traditional SSL certificates provide security for a single fully-qualified domain name, and Wildcard certificates can only cover all first-level subdomains of a domain, one Comodo UC Certificate can be used to secure the following Exchange Server 2007 domains:

• webmail.universe.com
• autodiscover.universe.com
• mail.universe.com
• exchange.server.local
• exchange.server.net

Key features include:

• Simplified management with a single certificate to support multiple domain names, host names and server applications
• Fully trusted and recognized by over 99.3% of email clients and web-browsers
• Unlimited certificate re-issuance – have the certificate re-issued for free whenever changes are made to domain names
• Now available in lifetime up to three years

“Microsoft Exchange is the most popular business messaging platform in the world. Comodo is one of a select group of Certificate Authorities that can offer these certificates, compatible with Microsoft Exchange,” said Melih Abdulhayoglu, CEO and Chief Security Architect of Comodo.

With companies using these new communications servers more and more, the term extension of these certificates represents a cost-effective improvement for businesses of all sizes.
