DALLAS– May 19, 2004 – Entrust, Inc. [NASDAQ: ENTU], a world-leading provider of Identity and Access Management solutions, today announced its intent to purchase intellectual property and certain other assets of AmikaNow! Corporation, a privately-held provider of e-mail content scanning and anti-spam tools designed to help enterprise and government customers comply with corporate e-mail policies and regulatory guidelines such as the Health Insurance Portability and Accountability Act (HIPAA), Gramm-Leach-Bliley (GLB) and the Canadian federal government’s Personal Information Protection and Electronic Documents Act (PIPEDA).

The two companies have entered into a letter of intent for the acquisition of AmikaNow!’s advanced content scanning and analysis technology, which is expected to close later this calendar quarter subject to approval by AmikaNow!’s shareholders and other customary closing conditions. The addition of this technology will further strengthen and expand the portfolio of products within the Entrust Secure Messaging and Secure Data Solutions. Using highly sophisticated content analysis tools, the technology automatically analyzes and categorizes e-mail message and document content based on the contextual meaning, not simply pre-defined word lists. Policies can be customized to suit the corporate environment and be automatically enforced at the boundary to help customers reduce business risk and comply with privacy and securities laws including HIPAA, GLB, PIPEDA and various SEC regulations. For example, in an e-mail environment this technology can be used to intercept and forward sensitive messages to a boundary encryption server, warn employees about their use of appropriate or offensive language, filter spam on incoming messages and much more.

“This acquisition will give us leading capabilities to expand the breadth of our solution portfolios,” said Bill Conner, chairman and CEO, Entrust, Inc. “Entrust customers will benefit from a modular yet comprehensive secure messaging product suite that addresses the emerging secure email boundary market including policy management, content filtering, anti-spam, anti-virus, boundary and end-to-end email encryption.”

Entrust will brand and integrate AmikaNow!’s technology within its solutions portfolio and is targeting initial product deliverables by the end of Q4, 2004. The company also intends to offer Entrust-branded advanced content analysis capabilities as standalone products to customers.

According to a recent Forrester Research report written by Jonathan Penn and Jan Sundgren, content security - the management of security threats and other problems associated with content like Web traffic, e-mail and other messaging - continues to rise on the agenda of corporate IT security concerns. Forrester has recommended implementing a comprehensive content security strategy that addresses all the problems associated with content.*

The unique advanced content scanning and compliance technology developed by AmikaNow! is based on research and development advances in information theory and artificial intelligence, which contribute to a more robust e-mail compliance solution.

It is anticipated that some of AmikaNow’s technology team will join Entrust within its marketing and products group headed by senior vice-president Kevin Simzer. AmikaNow! founder, president and CEO, Dr. Sue Abu-Hakima is also expected to join Entrust to help advise on product integration and strategy.

“We are extremely excited that our innovative products and technology will be offered to Entrust customers and continue to grow within Entrust,” said Dr. Sue Abu-Hakima. “Approximately 97 percent of business communication today is through email. Email is the double-edged sword which makes an enterprise very efficient, but at the same time opens it to significant risk and is grinding to a halt under the overwhelming burden of spam and viruses This is why email policy implementation and monitoring is critical. Our advanced content analysis goes well beyond basic keyword pattern matching to provide context-based analysis of e-mail message content, helping protect employees and organizations from liability in this increasingly regulated sphere.”

Financial terms of the planned acquisition were not disclosed.
