Vonage Selects Aladdin eToken to Enhance Data Security for its Employees

Aladdin Knowledge Systems (Nasdaq:ALDN), the leader in Software DRM, identity management, and content security solutions, today announced that Vonage Network Inc., a subsidiary of Vonage Holdings Corp., a leading provider of broadband telephone services, has selected Aladdin's eToken NG-OTP user authentication solution to provide its employees with enhanced mobile PC and file security.

The Aladdin eToken, which is about the size of an average house key, is easy to use and highly portable, providing users with powerful authentication by requiring something they have, the tamper-proof eToken, and something they know, a password. With the adoption of Aladdin eToken, Vonage is gaining One-Time Password technology based on industry-endorsed OATH (Initiative for Open Authentication) standards.

"Aladdin eToken's support for OATH standards was pivotal in our decision to select Aladdin," said Louis Mamakos, CTO of Vonage. "Vonage looks forward to all of its employees gaining extra data security by using Aladdin's NG-OTP eToken."

"The flexibility of Aladdin eToken NG-OTP fits perfectly with Vonage's requirements for both USB and OTP authentication," said Dan Pfeifle, senior director of eToken solutions for Aladdin North America. "We see a fast-growing number of organizations seeking highly flexible, open device hardware. Aladdin is pleased to have Vonage as one of its newest eToken customers."
