Commtouch Releases Version 4.1 - A Comprehensive Enterprise-Grade Anti-Spam Solution.

MOUNTAIN VIEW, Calif. -- Commtouch(R) (Nasdaq:CTCHC), the developer of ground breaking RPD(TM) technology for real time anti-spam and zero-hour virus protection, announced today the release of its Anti-Spam Enterprise Solution Version 4.1. In addition to the well-documented advantages of previous versions -- ground-breaking spam filtering and accurate detection performance -- Version 4.1 adds unique new capabilities to create a comprehensive on-premises anti-spam software solution that is particularly suited for large multi-site enterprises. Unique benefits of Version 4.1 include:

Multiple Entry Points

Commtouch 4.1 is designed for sophisticated enterprise networks in which email flow is routed through multiple entry points. It supports decentralized deployment, while providing the centralized management and administration IT managers need.

Powerful Reports Engine

With Commtouch reports, the IT manager is always in control, receiving detailed data on how much spam hits the enterprise, how much is blocked and why, which users are more vulnerable, etc. The IT manager has 11 reports to choose from and customize -- and each can be pre-scheduled, printed, viewed online and even exported.

User Interface Available in Three Languages

Commtouch takes its state-of-the-art user interface one step further by introducing user interfaces in English, French, and Spanish.

The Front-Running Solution for Distributed Enterprises

"Analysts and customers alike have already placed Commtouch at the top of the list of enterprise-grade anti-spam software solutions, and the new version will consolidate this position," said Tim Straight, Commtouch's vice president of Sales. "The unique features introduced in Version 4.1 create an unbeatable value proposition for the large enterprise space."

Yossi Maslaton, vice president of Network Operations and Customer Services at Commtouch, added, "Customers and resellers are our priority, and Version 4.1 was developed after listening to their feedback. Long-term collaboration with very large enterprises has given us a precise understanding of their needs -- and Version 4.1 was designed for them. We have created a solution that fits smoothly into organizations with highly complex messaging infrastructures, including multi-platform, multi-site and even multi-national networks."

The Choice of Analysts and Market Leaders

Commtouch 4.1 is a further enhancement to an already highly successful enterprise-grade anti-spam solution. It has been implemented by hundreds of enterprises, including corporate networks with up to 95,000 users.

The success of Commtouch enterprise solutions can be attributed not only to their industry-leading spam detection and accuracy, but also to their outstanding ease-of-use for end-users and IT managers. Commtouch Enterprise Anti-Spam Solutions have been shown to offer:

--Superior Spam Detection: Like previous versions, Commtouch 4.1 is based on Recurrent Pattern Detection(TM) (RPD), Commtouch's patented technology. RPD is the only technology that detects new spam outbreaks in real-time, as soon as they are distributed and before they reach the customer's network.

--IT Friendly: Commtouch solution is deployed in less than 30 minutes -- and provides full support for any email platform and network architecture. To the IT it offers flexible control and configuration, fully automated operation and convenient user-group management.

--User Friendly: Commtouch solution offers powerful end-user control including personal quarantine and personal policy management, yet requires no user-side installation.
