EnGarde Secure Linux

Award-winning secure operating platform combines ease of management with
unsurpassed security as a primary focus.

ALLENDALE, NJ-February 9, 2004 -- Guardian Digital, Inc., the world's
premier open source security company, today announced the next generation,
award-winning EnGarde Secure Linux (http://www.engardelinux.org).
Leveraging the best open source applications available, combined with the
security expertise from Guardian Digital, EnGarde delivers features
designed to ease the process of building a complete Internet presence and
the level of security necessary to prevent system compromise.

"The proactive security improvements inherent into its design are one of
the primary factors in the success of EnGarde," writes Pete O'Hara, vice
president of engineering at Guardian Digital. "Coupled with the most
sophisticated open source Web-based management system, EnGarde consistently
protects users from even debilitating kernel security vulnerabilities where
other Linux vendors fail."

EnGarde features secure web-based management of all functions, including
Internet edge services (Web, DNS, email), integrated intrusion detection,
cryptography, improved authentication and access control, as well as
protection from many forms of intrusion such as buffer overruns and denial
of service attacks. Enhanced availability and access control mechanisms
delivers a potent combination suitable for the largest
enterprise. "Security management is an essential component of any
successful online operation.  Mitigating security risks through the use of
a dynamic, rapidly-evolving development process bolstered by collaboration
of the open source community provides the most efficient form of
protection," writes Paul Brisson, orthopedic spinal surgeon, New York
Spinal Care.  "EnGarde Secure Linux and its secure-by-design approach
combined with the security benefits engineered by Guardian Digital offer
the best in proactive protection," continues Brisson.
