Independent Tests Applaud OEM's "Powered by Mailshell" Filters

SAN FRANCISCO - March 26, 2012 - Email spam filters that are 'Powered by Mailshell', the leading provider of Internet security engines for OEMs, out-perform most competitors' products according to a series of recent independent tests and reviews. In the last two months, 'Powered by Mailshell' filters sold by Prague-based Avast Software, Oslo-based Norman ASA, and U.S.-based GFI Software have demonstrated greater accuracy than nearly all industry competitors, including IBM, Symantec, Intel/McAfee, Sophos and others. Thousands of companies, and millions of consumers worldwide, rely on Powered by Mailshell filters for spam filtering, phishing detection, web security and DNS security.

"Our growth and success is based on providing our OEM partners with better results and higher ROI than all other alternatives," said Eytan Urbas, vice president at Mailshell. "These independent tests demonstrate exactly what our partners expect of us, and the primary reason they choose us."

The March 2012 VBSpam Comparative Test, the industry's premier independent testing program, cited a detection rate of 99.75% for GFI MailEssentials, a "Powered by Mailshell" filter, along with a false positive rate of only 0.04%. GFI's product also did not block a single legitimate newsletter. While most products' overall accuracy scores declined since VBSpam's November 2011 test, GFI's improved, scoring higher than IBM, Symantec, McAfee, Sophos, Kaspersky and other large Internet security vendors. The VBSpam tests are administered by Virus Bulletin and benchmark leading vendors' filters using identical streams of email.

Mailshell's OEM partners saw similar successes in recent reviews in PC Magazine. According its most recent tests, both Avast and Norton catch more "undeniable spam" than nearly all competing solutions, including those from Norton (Symantec), McAfee, Trend Micro, G Data, Panda, Kaspersky, Zone Alarm, F-Secure, and Bitdefender, among others.

A March 2012 review of Avast's Internet Security in PC Magazine cited the product's "simple, accurate spam filter". The review cited a detection rate higher than nearly all competing products and a false positive rate of only 0.2%, also among the industry's best. PC Magazine also glowed about the spam filter in Norman Security Suite 9 Pro, another 'Powered by Mailshell' filter. The January 2012 review called Norman's spam filter "amazingly accurate" and "among the best of current suites." The product's false negative rate was "less than any current suite."
