August 2, 2001

OAKBROOK TERRACE, Illinois and BRUSSELS, Belgium – August 2, 2001 – VASCO (Nasdaq NM & Nasdaq Europe: VDSI; www.vasco.com), a global provider of enterprise-wide security products that support e-business and e-commerce, today announced VACMAN Server 6.0 for secure web access to Citrix® software. Citrix Systems, Inc. (Nasdaq: CTXS; www.citrix.com), an international leader in application server software and services, provides multiple-user access to distributed applications via the web with any standard browser from any device, platform, or network connection. Working seamlessly with the Citrix Nfuse and MetaFrame central servers, VACMAN Server 6.0 provides secure virtual single sign-on capabilities and centralized management functions to Citrix users. And because VACMAN Server supports VASCO’s Digipass family of strong authentication and digital signature platforms, Citrix customers can easily gain the benefits of strong, two-factor authentication, enhancing the authorization and administration capabilities of VACMAN Server.

“VASCO is an established market leader providing strong and flexible authentication, authorization and administration security software across the platforms, environments, and applications used by businesses today,” said Mario Houthooft, President and CEO of VASCO. “Our VACMAN product line enables fine-grained access control and remote access security for web, LAN, and enterprise, offering security for web portals, access to corporate networks, and market-leading applications such as Microsoft Exchange Outlook Web Access and now Citrix. While other security vendors are now working to broaden their market reach to catch up to the security needs of businesses, VASCO has proven its success in this arena with more than six million users worldwide, including more than 170 banks and 500 corporations that rely on VASCO for security that works.”

Thousands of companies worldwide use Citrix to access distributed applications, including 99 of the Fortune 100, 90 percent of Fortune 500 companies, and more than half of Europe’s Financial Times FT 500. Now these customers can implement strong authentication and ensure that only authorized users are accessing their applications by implementing VACMAN AAA security. Fully integrated with the Digipass family of products, VACMAN verifies the user’s identity through two-factor authentication and dynamic passwords, while providing digital signature capability to ensure the integrity of data and remote transactions.

“VACMAN Server 6.0 for Citrix offers a centralized, flexible and cost-effective solution for managing secure access to Citrix software,” said Mark Kefford, Vice President of Product Strategy for VASCO. “It has the flexibility to operate across all the Citrix platforms – particularly Windows NT, Windows 2000, Linux and Solaris – and can be easily configured to match the environment needs of each organization, whether protecting an individual Citrix server or many servers geographically dispersed, offering application or user-specific access control with activity accounting capabilities to track a user’s session, or enabling third-party authentication support. And because VACMAN can run on the same web host as the Citrix front end, it can provide a seamless application for enabling strong authentication to resources on a common web server.”

VASCO secures the enterprise from the mainframe to the Internet with infrastructure solutions that enable secure e-business and e-commerce, protect sensitive information, and safeguard the identity of users. The Company's family of Digipass® and VACMAN® products offers end-to-end security through strong authentication and digital signature, true and secure Single Sign-On, access control, and web portal, LAN, and enterprise security, while sharply reducing the time and effort required to deploy and manage security. VASCO's customers include hundreds of financial institutions, blue-chip corporations, and government agencies in more than 50 countries. More information is available at www.vasco.com.
