GUARDIAN DIGITAL LAUNCHES NEXT GENERATION 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. 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 compromises.

"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

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,

approach combined with the security benefits engineered by Guardian
Digital offer the best in proactive protection," continues Brisson.
