Subject: NEW PRODUCT ANNOUNCEMENT

  GUARDIAN V5.0 Security Suite available for LINUX on IBM Mainframe O/S 390.

A newly released version provides Mainframe users running LINUX complete
user authentication, user account management administration facilities as
well as password synchronization options which substantial improve the
security and deployability of LINUX on O/S390.

Until now Mainframe user had to rely upon basic LINUX account and password
management which often vary by the type of LINUX machine in use (IBM AIX, HP
10.2 and 11 etc.) and is often woefully inadequate.  The alternative of
using RACF under VM to authenticate access has many overheads associated
with it.

Now with GUARDIAN Mainframe users have a single easy to use yet highly
secure method, which eliminates UNIX differences, providing the cross
platform and multiple domain management required to enforce security.

The GUARDIAN Security Suite supports most aspects of the IBM   environment;
interfacing with RACF and ACF/2 on OS/390, SMIT in the AIX environment and
the Tivoli framework while maintaining true platform and operating system
independence.

The GUARDIAN Security Suite permits full integration and allows you to
harness the power of your existing investments in IBM technology while
building a secure interoperability infrastructure for the future.

The GUARDIAN Security Suite delivers unparalleled performance, secure
deployment and plug compatibility across the   environment while reducing
the total cost of ownership for enterprise wide security. GUARDIAN for LINUX
O/S390 is available for selected customers with planned General Release in
September 2001.
