Commtouch Expands Presence in Service Provider Market with Major Wins.

Outbound Spam Protection Solution Achieves Traction with Service Providers Seeking to Reduce Operational Costs and Increase User Satisfaction

SUNNYVALE, Calif. -- Commtouch[R] (Nasdaq:CTCH) today announced that during the first quarter of the year, it enhanced its presence in the service provider market by gaining new customers and expanding existing relationships with leading service providers.

Included in the group of new service provider customers that selected Commtouch are:

* Cox Communications, one of the top three broadband communications providers in the United States, which selected Commtouch's Anti-Spam and Outbound Spam Protection solutions

* Superb Internet, an award-winning US-based hosting provider that selected Commtouch's Outbound Spam Protection solution

* One of the top three hosting providers in Europe, which selected Commtouch's Anti-Spam and Command Antivirus[R] solutions to protect its subscribers

Commtouch launched its Outbound Spam Protection solution for service providers last year to cope with one of the biggest problems email service providers are faced with today: the abuse of their messaging infrastructure for the distribution of spam, phishing and viruses, which can lead to increased operational costs, legal exposure and customer dissatisfaction. The Commtouch solution was designed specifically to block this abuse and identify its origin.

"We have been expanding our footprint in the service provider market, offering hosting providers, ISPs and SaaS providers a consolidated offering geared towards their specific requirements for scalable performance, dedicated support and implementation flexibility," said Ido Hadari, Commtouch's chief executive officer. "We are pleased with the response of leading service providers to our proposition of operational simplicity and lower TCO, and remain committed to supporting their needs."
