NW_20010619_en_VASCO Extends Partnership with Siemens by Providing Secure, Transparent Wireless Transactions

June 19, 2001

COMMUNICASIA CONFERENCE, SINGAPORE – June 19, 2001 – VASCO (NasdaqNM & Nasdaq Europe: VDSI; www.vasco.com), a global provider of enterprise-wide security solutions that support e-business and e-commerce, today announced that it is making wireless communications and transactions more secure, transparent, and ubiquitous. The new SL45i Java Phone from Siemens (SI.N; SIEGnq.L; www.ic.siemens.com/mobile-business), a worldwide leader in electronic communications, is the latest mobile platform to be enabled with VASCO’s Digipass® strong authentication and digital signature security software. With security seen as one of the key stumbling blocks to full-scale m-commerce, telecommunications companies can now market a full range of wireless transactional services to their corporate and end-user customers, while ensuring that their personal information and mobile transactions are safeguarded against unauthorized use.

“Siemens is just one example of how VASCO is providing the enabling security infrastructure allowing telecommunications service providers to generate new revenue streams by introducing new transaction-based services into their markets,” noted Mario Houthooft, President and CEO of VASCO. “And because Digipass provides end-to-end secure data exchange between the end-user and the m-commerce store or financial institution, without relying on the underlying wireless connectivity infrastructure, it provides security for all present and future wireless networks, from GSM, GPRS, and UMTS to future 3G networks, including SMS functionality. We’re finding that mobile device and SIM card manufacturers, telecommunications service providers, financial institutions, and application service providers are all integrating security as a critical business component of their product and service offerings.”

Siemens SL45i Java Phone is a mobile “Smart” phone, with features that include an MP3 player, digital voice recorder, personal organizer, and many other intelligent features enabling true mobile communication. With Digipass, the SL45i turns into a personal security device, creating strong user authentication and digital signatures for secure m-commerce transactions. The versatility of the Digipass-enabled SL45i allows for a multitude of applications ranging from wireless mobile commerce and mobile banking to more traditional phone/fax banking to network security, remote office, and telecommuting applications. And because all members of the Digipass family feature full interoperability, organizations already using Digipass can easily incorporate remote access using SL45i Java Phone without changing their existing infrastructure.

“Integrating Digipass security into our new SL45i Java Phone continues our successful partnership with VASCO that began with Digipass on the Siemens SX45 wireless PDA for Pocket PC, introduced in March of this year,” noted Bernhard Geisberger, Director Partner Program, Siemens Information and Communication Mobile. “We are taking the lead on providing strong yet transparent mobile security to all our customers, by joining forces with one of the leading players in the security industry.”

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.
