HERNDON, Va.--(BUSINESS WIRE)--Oct. 20, 2003

Solution Suite Enables High Assurance Secure Interoperability for Defense, Intelligence, Homeland Security, Law Enforcement, First Responders and Diplomatic Community

DigitalNet (NASDAQ:DNET), a leading provider of network computing for the enterprise, today announced the latest version of its XTS solution suite - XTS-400 -- which enables organizations to securely share data at different classification levels depending on a user's clearance authorizations all from one computer. The XTS' secure platform is interoperable across multi-jurisdictional domains and allows collaboration among different networks while providing high-level assurance to control information exchange in both wired and wireless environments. The XTS solution suite, already proven and widely utilized in over 600 installations in the U.S. Department of Defense and intelligence communities, is ideally suited for enabling high assurance control of information exchange among homeland security, law enforcement, first responders, coalition partners and the diplomatic community.

"For many years, our customers have come to rely on our high assurance, certified technology to facilitate decision-making through fast, efficient and secure access to sensitive information," said Bill Anderson, senior vice president of DigitalNet's Secure Interoperable Solutions. "Our XTS-400 solutions suite is particularly well suited to those entities involved in the functions of multi-level secure collaboration between enclaves of varying levels of sensitivity."

Since 9/11, the need for information integration among multiple agencies has come to the forefront, especially given the communications challenges of securely sharing electronic information among the 22 agencies comprising the U.S. Department of Homeland Security. Before the XTS, the only secure option in protecting classified and sensitive information was to deploy multiple single level networks and even multiple PCs for each user, using physically separate systems for processing data at each classification level. The XTS eliminates the need for replication of computer systems and networks by enabling a single trusted server to have simultaneous access to data at multiple classification levels and by using secure guard technology to provide for the releasability control of authorized information to end users.

XTS-400 allows authorized releasable data to safely pass from one protected classified level to another while guarding against the transfer of unauthorized information. Network Guard applications operating on the XTS-400 enforce well defined security release policies in rigorously examining requested data from a network at one level and then making decisions about whether that data should be allowed to pass through to another network and ultimately to an end-user that may be at a different classification level. The new XTS-400 solution suite offers full LINUX compliance in terms of the operating system application interface and also utilizes the latest Intel Xeon chip set hardware speeds. This means that the XTS-400 can now be used as a trusted server base for a wide variety of different commercial LINUX compliant software applications including the Apache Web server application.

A few of the applications already available on the XTS-400 server include:

-- S/MIME ESSv3 Secure E-mail Guard

-- Apache Web Server

-- "Data Sync" Database Guards

-- Trusted Directory Guard

-- SMTP E-mail Guard

"The XTS-400 solution suite enables government agencies and corporations to reduce costs by providing efficient and security controlled access to classified and unclassified information from one desktop," stated Dr. George Webber, vice president and chief scientist of DigitalNet's Secure Interoperable Solutions.

Not only does the XTS-400 solution suite operate in a wired environment, it also has the ability to negotiate communication through a wide array of wireless devices like cell phones and PDAs, which are in increasing use today. The XTS has been evaluated by the National Security Agency (NSA) and received a B3 rating (EAL5+ equivalent) in accordance with NSA's Trusted Computer System Evaluation Criteria (TCSEC), which is the highest rating within the TCSEC category and second highest federal security level.
