Unified Communications Certificates Yet Another Example of the Expansion, Flexibility and Interoperability of PKI-Based Solutions

    Entrust collaborates with Microsoft to verify compatibility with Exchange
    Server 2007

    DALLAS, March 22 /CNW/ - What most consumers don't realize is that the
use of public key infrastructure is universal in today's most routine tasks.
Online bank transfers. Simple border crossing via e-Passports. Basic Internet
transactions. That same technology is the foundation of Entrust Unified
Communications Certificates.
    In collaboration with key industry leaders, Entrust, Inc. (Nasdaq:   ENTU)
offers Entrust Unified Communications Certificates, which secure and
authenticate communication between mail servers (internally between the
Exchange servers, and between Microsoft(R) Exchange servers and other mail
servers). In addition, administrators can enable the new Auto Discover
provisioning feature provided by Microsoft Office Outlook(R) 2007 and Outlook
Web Access through Microsoft Exchange Server.
    Unified Communications refers to an industry trend of bringing multiple
communication methods together into a unified management and usage context.
The technology serves as a versatile management system that affords users the
ability to track and respond to a range of communication options (e.g.,
e-mail, voicemail, instant message, fax, etc.).
    "Protecting all communication, no matter how it is implemented or by
whom, is a vital necessity for any security-conscious organization. Entrust
Unified Communications Certificates provide useful flexibility and
interoperability for protection of Unified Communications deployments," said
Entrust Chairman, President and Chief Executive Officer Bill Conner.
    The ability to leverage public key infrastructure to solve a variety of
business challenges is one of the latest trends in digital security. This new
strategy, coined "PKI 2.0," can help organizations answer specific security
obstacles with a trusted technology that is used across the world -- even in
the most common, everyday implementations.
    "The development of Unified Communications Certificates is a prime
example of evolving public key infrastructure technology to easily and
transparently address the business challenges of today, and the future of
online communication," said Michael Osterman, president of Osterman Research.
"Having the capability to access and manage multiple channels of communication
safely and confidently will serve as a useful resource in consumer and
enterprise implementations."
    To support industry-leading products, Entrust worked closely with the
Microsoft Corporation to verify compatibility with a variety of the most
innovative communication products available today, including Microsoft
Exchange Server 2007 and Microsoft Live Communications Server. Entrust Unified
Communications Certificates are suited for environments that typically need to
encrypt communications across a wide range of protocols and domains, both
internally and externally. This technology enables organizations to secure
communications with large numbers of specific hosts and domains with a single
certificate. Entrust Unified Communications Certificates specify which hosts
and domains are to be protected, giving organizations greater control and
better security.
    "Secure online communications are pivotal in today's organizations," said
Trevor Freeman, program manager for Domain Security in the Exchange Product
Group at Microsoft. "The Exchange Server 2007 release includes enhancements in
confidential messaging, operational efficiency and deployment that push the
envelope of existing SSL certificate offerings. It has been a pleasure working
with Entrust toward the release of their Unified Communications Certificates
to help address the needs of our customers."
    Entrust Unified Communications Certificates can help reduce upfront and
ongoing management costs by using a single certificate on multiple customer
servers. This not only helps limit upfront certificate costs, but also means
organizations are only required to manage and renew a single certificate over
    Unlike "wildcard" SSL certificates, Entrust Unified Communications
Certificates are more secure because they specify exactly which hosts and
domains are to be protected. Wildcard SSL certificates are configured to be
used with a domain (e.g., company.com) and every domain server behind it
(e.g., your.company.com, any.company.com, etc.). This tactic can prove
cost-effective, but also risky since it is not possible to fully control where
the certificate is used, or for what purpose. The certificate could
potentially be used on unauthorized or even fraudulent sites within the same
domain (e.g., phish.company.com).
    Entrust Unified Communications Certificates have already been deployed on
customers' Exchange Server 2007 servers and are available now for purchase
