ALDN Aladdin Knowledge Systems Ltd (MM)

Aladdin Knowledge Systems (NASDAQ: ALDN), an information security leader specializing in authentication, software DRM and content security, today announced that Aladdin eToken(TM) and Aladdin SafeWord(TM) have been verified as Citrix Ready(TM). The Citrix Ready program helps customers identify third-party solutions that add the greatest value in Citrix Application Delivery Infrastructure solutions. eToken and SafeWord have completed a rigorous verification process to ensure compatibility with Citrix� Access Gateway(TM) and Citrix XenApp(TM).

The Citrix Ready program makes it easy for customers to identify complementary products and solutions that can enhance Citrix environments. Aladdin and Citrix customers can be confident that eToken and SafeWord have successfully passed a series of tests established by Citrix and can be trusted to work effectively with leading thin client solution providers and Access Gateway and XenApp.

Aladdin and Citrix will provide an integrated mobile roaming solution for enterprise and service providers to secure access to corporate application and assets, reducing both cost and complexity of IT infrastructure and improving data availability and reliability. The integrated solution delivers secure mobile worker portability and maintains productivity for browser-based Web virtualization access to sensitive corporate resources.

By enforcing two-factor authentication with Citrix virtualization technology, organizations can reduce costs associated with maintaining a secure IT infrastructure and prevent data-loss and unauthorized access to personal computers and workstations while increasing productivity by enabling remote employees to connect to corporate resources from any computer at any time.

Citrix Ready products are featured in an online catalog at www.citrixready.com and carry the Citrix Ready logo.

"As part of the new Aladdin Authentication Business Unit strategy, Aladdin is strengthening relationships with strategic partners for both Aladdin eToken and Aladdin SafeWord," said Phil Pavay, vice president, business development at Aladdin Knowledge Systems. "Aladdin is renewing its longstanding eToken-Citrix relationship and incorporating the new Aladdin SafeWord line to create solutions at the forefront of remote office and mobile computing technology by enabling strong authentication to fit any corporate infrastructure, whether they are using smartcard-based certificates or advanced OTP access."

Aladdin eToken USB-based smartcard generates and stores users' personal credentials, such as private keys, passwords and digital certificates, inside the encrypted environment of the on-board smartcard chip. In order to access applications from outside the organization's protected network, the user verifies his identity with both a password and the eToken device. This unlocks the personal credentials and creates an encrypted connection between the user's computer and the organization's network without exposing the user's private information to the PC environment.

Aladdin SafeWord offers secure One-Time-Password (OTP) access to Citrix remote applications, requiring no additional software on the client's workstation. SafeWord 2008 is compatible with Citrix products including Access Gateway, XenApp, Citrix Access Essentials, and Citrix GoToMyPC Corporate.

Also available for use with Citrix products is Aladdin's Token Management System (TMS), which maintains data on every eToken and SafeWord device and allows the organization to track, update and maintain authentication devices in the organization to add or remove users and enforce organizational policy.
