--RPD(TM), the only technology that detects new spam outbreaks in real-time, immediately they are distributed and before they reach the customer's network.

--Commtouch Detection Center - analyzes non-invasively over 30 million emails daily

--Deployment in less than 30 minutes, coupled with top level IT flexibility.

--Effortless, fully automated operation: Once set -- no further IT involvement is needed.

Gideon Mantel, CEO of Commtouch, noted: "Version 4.0 provides solutions for all aspects of the spam epidemic plaguing the enterprise: easy deployment, no maintenance, best user experience and exceptional spam filtering performance. In Version 4.0, IT departments will find flexibility and control offered by no other solution. The addressable market for Commtouch channels is also broadened with its suitability for enterprises of all sizes using any messaging platform."

Commtouch Solution 4.0 is rapidly gaining increasing interest in the industry.

Michael Osterman, President of Osterman Research Inc. said: "Independent testing of the Commtouch Recurrent Pattern Detection technology has shown that it blocks at least 97% of spam and generates near zero false positives. Among the best in the industry in both categories, Commtouch has overcome the vicious trade-off between efficiency and accuracy."

According to Mark Levitt, VP Research, Collaborative Computing at IDC: "IT departments spend substantial amounts of time managing anti-spam solutions. With Version 4.0, Commtouch is responding directly to the growing customer demand for solutions that require minimal staff resources."

Deji Akomolafe, technical lead of IT Infrastructure at Roxio (Nasdaq:ROXI), provider of top selling digital media software, said: "With Commtouch 4.0, users are in complete control of their own quarantine, saving IT the hassle, but without installing anything on the user side -- best for users, easiest for IT."

The innovative Interdisciplinary Center in Herzliya, Israel's most prestigious private institution for higher education, with hundreds of courses and 8,000 students and faculty mailboxes, is one of the first beta customers of Version 4.0. Guy Trutiak, chief technology officer, noted: "We were up and running in 30 minutes flat and results were immediate. The product is very flexible, providing control and configuration on the fly. For us, the importance of implementing an anti-spam system was critical for improving the service to students and faculty with the most effective technology available".

Professor Shimon Schocken, Dean of the Efi Arazi School of Computer Science in the Interdisciplinary Center commented: "With 98% of spam filtered out, and not a single false positive, it's fair to say that for us, spam is now history. Well done Commtouch."

John Papaioannou, President of Promenet, a U.S. East Coast value-added reseller (VAR) and one of the first resellers to distribute Commtouch 4.0, notes: "Commtouch's RPD technology does all that an IT manager would want in an anti-spam solution -- it takes less than 30 minutes to install, requires no on-going IT management. Even better, it works. This is the highest detection rate we've seen with almost no false positives!"
