OAKBROOK TERRACE, Illinois and ZURICH, Switzerland – May 07, 2008 - VASCO Data Security International, Inc. (Nasdaq: VDSI) (www.vasco.com), the leading software security company specializing in authentication products, today announced that leading Brazilian bank Banco Itau (www.itau.com.br ) will protect the users of its retail e-banking application with VASCO’s VACMAN Controller and Digipass GO3

Banco Itau, one of Brazil’s largest privately owned banks, is a longstanding customer of VASCO. Five years ago, the bank started securing its corporate customers with VASCO’s strong authentication products. Today, the bank will use VASCO’s market leading Digipass-VACMAN combination in order to safeguard its retail e-banking application.

Brazil is an important market for VASCO. The country has a mature and popular Internet banking channel and the banks are actively looking for ways to make the Internet a secure and easy to use business channel. Brazil can safely be regarded as a shining example of banking-related IT-excellence on the American continent. In 2007, VASCO opened a sales- and support office in Sao Paulo, the business capital of Brazil.

Digipass GO3 is a lightweight strong user authentication product, especially designed for the large volume banking market. GO3 is extremely easy to use - with a simple touch of a button, the customer generates a unique one-time password. The password can be only used once, which means that it can’t be re-used by fraudsters. Digipass GO3 is VASCO’s answer to banks that want to give their customers a simple though secure means to use Internet banking applications.

“We are very happy to extend our cooperation with Banco Itau,” said Jan Valcke, VASCO’s President and COO. “VASCO will put the combination of its expertise and experience as a global market leader in strong authentication and the expertise of its local staff at Itau’s disposal in order to guarantee a smooth roll-out and a successful project. Together, we’ll make the Internet a safer place.”
