GUARDIAN DIGITAL LAUNCHES OPEN SOURCE SECURE MAIL SUITE

Secure Mail Suite Available with New Version of
Award Winning Secure Linux Operating System

Allendale, New Jersey---March 3, 2003---Guardian Digital, Inc., the 
leading open source security company, today announced the availability of 
the Guardian Digital Secure Mail Suite, the industry’s most secure and 
cost-effective email platform. Designed to meet the needs of small 
businesses, enterprise level companies, ISPs and ASPs looking to secure 
and manage corporate email operations, Secure Mail Suite is capable of 
managing all email functions within an organization. The suite increases 
employee productivity by simplifying management and drastically reducing 
junk mail, virus and Internet threats. Secure Mail Suite is currently 
available with Guardian Digital’s EnGarde Secure Linux v1.5, the newest 
version of the company’s award winning secure Linux server operating system.

“Guardian Digital is unique because its products are built with open 
source code," said Bill Claybrook, research director, UNIX and Linux, 
Aberdeen Group.  “While many believe this makes the product insecure, it 
in fact makes it more secure since many more developers are on the lookout 
for potential security breaches.  For companies looking to implement a 
secure system at a fraction of the cost, Guardian Digital offers a solid 
option.”

The cornerstone of Guardian Digital’s Secure Mail Suite is a robust, 
integrated anti-virus and anti-spam technology that scans all incoming and 
outgoing transmissions for junk mail, viruses, malicious code and file 
attachments and offensive content. Secure Mail Suite offers simplified 
administration capabilities to build a complete enterprise Internet mail 
environment and is engineered to scale to thousands of users and 
domains.  Through its use of advanced access control and authentication 
mechanisms, comprehensive auditing and reporting features, as well as 
encrypted communications facilities, Secure Mail Suite delivers protection 
from constantly evolving online threats for both internal and external 
mail systems.

“The perils relating to enabling email and Internet connectivity in the 
workplace have increased over recent years, so the need to quickly secure 
our corporate network and email became a high priority for us,” said Lars 
Baan, vice president of operations at Aalborg Instruments. “Guardian 
Digital carefully reviewed our security needs and implemented their 
cutting-edge technology rapidly and for a fraction of the cost of 
comparable solutions. The security suite is very stable, reliable and 
requires almost no administration. We now have excellent control of our 
email and network security, and Guardian Digital's customer support has 
been truly outstanding!”

  “Secure Mail Suite is the most secure and cost effective option for 
 companies looking to eliminate junk mail and manage everyday threats from 
 viruses that will bring the productivity levels of unsuspecting 
 individual’s to a screeching halt,” said Dave Wreski, CEO of Guardian 
 Digital, Inc. “Our mission is to continue providing companies with robust 
 Linux-based products that are not only cost effective but also offer the 
 highest levels of security, scalability and ease-of-management.”

Secure Mail Suite comes with many additional features, including:

·       Build full-featured ISP, ASP, departmental or enterprise mail systems.
·       Simple and secure Web-based management for all functions.
·       Comprehensive anti-spam protection utilizing dozens of 
technologies to intelligently analyze all email and provide consistent 
protection from rapidly evolving threats.
·       Protection from outside network eavesdropping using SSL & TLS for 
encrypted communications. Integrated certificate authority provides 
digital certificate management.
·       WebMail for secure remote access, LDAP, group scheduler, vacation 
auto-away and detailed real-time graphs and reporting for easy maintenance.
·       Sophisticated authentication mechanism ensures only authorized
