OAKBROOK TERRACE, Illinois and ZURICH, Switzerland September 21, 2010 - VASCO Data Security International Inc. (Nasdaq: VDSI; www.vasco.com), a leading software security company specializing in strong authentication products announces today that Leleux Associated Brokers, an independent Belgian stock broking firm, uses DIGIPASS technology to secure access to its online stock broking application “Leleux On Line”.

With approximately 20,000 customers and more than 120 employees, Leleux Associated Brokers is one of Belgium’s largest stock broking firms. The company is a member of various stock exchanges and provides its customers with real time access to NYSE-Euronext, NYSE Life, the Luxembourg Stock Exchange, Xetra and the London Stock Exchange.

Leleux Associated Brokers became the first virtual stock broker in Belgium when it launched its web based application “Leleux On Line” allowing its customers to consult and manage their stock portfolio in real time 24/7 from any computer with an internet connection. The current version of the application is accessible for all users regardless of which operating system or platform they use (Mac, Smartphone,…).

The application provides customers with a complete transaction history allowing them to execute order transactions in real time without human intervention and transfer cash to indicated bank accounts. Leleux On Line requires an online subscription which is free of charge.
In version 5.2 of Leleux On Line, expected in the coming months, new features will be introduced, facilitating user experience and increasing user friendliness.

To secure access to the application, Leleux Associated Brokers deployed VASCO’s DIGIPASS technology allowing the company to ascertain the identity of the person wishing to consult its portfolio and/or place orders online. The PIN protected DIGIPASS 251 calculates dynamic passwords enabling secure authorized access to the application hereby fulfilling the authentication requirement. In order to guarantee non-repudiation, all transactions made through Leleux On Line must be signed with a digital signature generated by DIGIPASS.

“Leleux Associated Brokers needed a security solution that could guarantee data integrity as well as the confidentiality of all online transactions,” says Olivier Leleux, Managing Director at Leleux Associated Brokers. “With the PIN protected DIGIPASS 251, VASCO provided us with the most suitable solution to fit our needs. Moreover, VASCO’s solution offers distinct advantages for our end-users by increasing the ease-of-use. Taking into account VASCO’s proven technology and experience, quickly convinced us to partner with them.”

DIGIPASS 251 has brought banking level security to Leleux On Line, providing the stock broking firm with e-signature technology that does not require smart cards. Additionally, the solution provided an answer to persistent compatibility difficulties with different operating systems, a problem Leleux Associated Brokers experienced with a previous competitor’s system.
Furthermore, when deploying DIGIPASS technology, no additional software needs to be installed on the end-user’s computer turning it into a true mobile solution that is accessible anywhere, anytime.
