HP ANNOUNCES SECURE, BROWSER-BASED OPENMAIL SOLUTION

Integration with VirtualVault Lowers Costs of Supporting Remote
E-mail Users, Allows Users Secure Access from any Web Browser

PALO ALTO, Calif., March 30, 1999 — Hewlett-Packard Company today
announced a new program that combines HP OpenMail with the HP
VirtualVault trusted Web platform, enabling organizations to reduce
the costs of supporting remote e-mail users dramatically while
greatly simplifying access.

The program integrates HP’s OpenMail enterprise messaging solution
with the HP Praesidium VirtualVault 3.5 trusted Web-server platform,
enabling organizations to provide remote users convenient and direct
access to their e-mail from any device that provides Internet access
via a standard Web browser. This solution is based on the next
version of OpenMail, which is being demonstrated this week at the
Electronic Messaging Association (EMA) conference in Dallas.

The integration of OpenMail and VirtualVault eliminates the need for
remote users to rely on dial-up networking or carry a laptop to
access e-mail from remote locations. OpenMail users simply access an
SSL-secured URL from any device with an Internet browser, including
PDAs, Web phones, walk-up terminals and PCs. The browser accesses
OpenMail Web client software located on a VirtualVault server. The
server then connects users to their OpenMail accounts on OpenMail
servers inside the corporate firewall.

With this solution, companies can reduce their investment in
remote-access systems, private networking, and associated support and
help-desk staff. HP estimates that it can cost organizations up to
$500 annually to support a remote user. By using OpenMail with
VirtualVault, organizations can reduce these costs by as much as 75
percent.

“OpenMail has always been recognized for its lowest total cost of
ownership,” said Nigel Upton, general manager of HP’s Communications
Software Operation. “Now, by extending OpenMail environments with
VirtualVault, organizations can greatly reduce the complexity and
costs of operating remote e-mail.”

VirtualVault uses trusted mandatory security mechanisms to block
sophisticated attacks on the OpenMail client, the boundary Web server
and internal corporate OpenMail servers. Attackers cannot modify Web
pages nor modify legitimate application code.

“As the demand for remote access expands, conventional managed
firewall systems don’t provide scalability,” said Roberto Medrano,
general manager of HP’s Internet Security Division. “This solution is
an excellent example of how VirtualVault delivers an innovative
solution that enables cost-effective, secure remote access to
mainstream corporate applications. Without VirtualVault, these
benefits would not be possible.”
