Major Israeli ISP Deploys Aladdin eSafe SecureSurfing Solution to Answer Businesses' Need for Protection Against Spyware, Phishing Threats

CHICAGO, December 14, 2006 - Aladdin Knowledge Systems Ltd. (NASDAQ: ALDN) the leader in Software DRM, strong authentication and content security solutions, today announced that a growing number of ISPs, including Smile-Internet Gold (NASDAQ: IGLD), one of Israel's largest ISPs, are implementing Aladdin's eSafe SecureSurfing™ solution to offer business customers unmatched, management-free security services. In addition to a successful, ongoing program that offers consumers "clean pipe" Internet access, a new Smile-Internet Gold offering brings the same award-winning service to businesses.

The eSafe SecureSurfing solution allows ISPs to offer a centralized security service that filters Web traffic before it reaches the surfer, freeing ISP subscribers of the hassle of maintaining desktop-based software to thwart threats such as spyware and phishing attacks. Subscribing businesses report they take advantage of the new service because their organizations cannot tolerate the higher risk and decline in production if spyware or phishing attacks affect them.

Announced less than a year ago as the first-ever technology designed for ISP-managed security services, eSafe SecureSurfing is experiencing interest from ISPs around the world. After unveiling the offering just six months ago, Internet Gold reports that a significant number of its consumer customers have chosen to subscribe to the service, named "Safety-Net" by Smile-Internet Gold.

"We see significant, ongoing potential for securing our business customers' Internet access via Aladdin's eSafe SecureSurfing solution, as it has proven to be a popular service for consumers, and business ISP subscribers need protection just as much," said Zvika Sheinfeld, vice president of marketing for Internet Gold. "It simply makes sense to offer centralized protection to customers who desire security from spyware and other threats, but who do not want to mess with the management of a desktop based solution. eSafe SecureSurfing is an innovative offering that allows us to provide a valuable, additional service that serves as a powerful differentiator from the competition."

For a monthly fee, Internet Gold ISP customers receive:

• Real-time Web surfing security with four-layer spyware blocking utilizing 15 anti-spyware technologies, stopping both standard and targeted spyware attacks
• Real-time Web surfing Trojan and worm blocking with full inspection of all Web page content
• Real-time Web surfing exploit, vulnerability, and AJAX client-attacks blocking - truly proactive security
• Web email security and antivirus effective for almost any web-based email service, including Hotmail, GMail, Yahoo! Mail, etc.

"Smile-Internet Gold's success with the eSafe SecureSurfing solution illustrates the beginning of an entirely new opportunity for ISPs - a valuable security service led by Aladdin's ongoing innovation and expertise in content security," said Shimon Gruper, vice president of technologies for the Aladdin eSafe Business Unit. "Not only does Smile-Internet Gold's fast adoption of eSafe SecureSurfing reinforce the great demand for ‘clean pipe' technology, but it also shows the great potential for ISP differentiation. Powerful security and no hassle - it's the combination ISPs from around the globe see as very appealing to businesses as well as home users."

On November 8th, Aladdin also announced that Transbeam, one of New York City's leading ISPs for hotels and schools, selected the Aladdin's eSafe SecureSurfing solution to offer the service to its business customers.
