DALLAS--(BUSINESS WIRE)--April 21, 1998--

Popular Desktop Management and Security Software is Now Available

in a Network Version for Windows 95/Windows NT Workstations

Citadel Technology Inc. (OTCBB:CITN) announced today the release of WinShield for Networks v.3.0 the latest edition of its desktop management and security software.

WinShield for Networks features powerful desktop configuration controls that help administrators more effectively secure their networked PCs. WinShield Network 3.0 offers support for Novell NetWare and Microsoft(TM) NT Server networks and for Windows 95 and NT workstations. It is installed and administered centrally from any Windows 95 or Windows NT network workstation.

"We developed WinShield for Networks in direct response to the needs of our educational and corporate customers. Administrators can now quickly and easily secure and control every workstation on the network from a central point greatly reducing implementation and administration time," said Steven B. Solomon, president and CEO of Citadel Technology.

With WinShield for Networks, administrators can assign different security levels, called profiles, to individuals and groups providing unlimited flexibility in defining your organizations security policy. WinShield for Networks applies the appropriate user security to any network computer the user logs on to. The installation and configuration of WinShield across your network workstations is made easier using Citadel's centralized administrator program. WinShield for Networks prevents changes to system settings such as desktop appearance, Control Panels utilities, hardware drivers, addition and deletion of printers, registry editing tools, performance settings, etc. These tools provide the best combination of features to help reduce the number of problems that generate the majority of technical support and repair calls.

Administrators can configure which applications users can access by shielding specific desktop program icons, "Start Menu" shortcuts, access to the DOS prompt or DOS applications and access to the "Find" command providing an additional level of security and simplifying the users desktop. To prevent the installation of unauthorized software, the administrator can restrict the use of the "Run" command, and access to the floppy drive, CD ROM, and the Internet.

"We believe that using WinShield for Networks greatly reduces problems caused by deliberate or accidental changes to the workstation settings and configuration," continued Solomon. "This helps lower overall operating and management expense by reducing the demand on in-house support and help desk resources."

WinShield for Networks has a suggested retail price of $259.00 for a ten-user license and requires Windows 95 or Windows NT.
