LETA, Leading Russian Security Vendor, Integrates Mailshell For Spam And Phishing Protection

MOSCOW and SAN FRANCISCO - July 7, 2008 - LETA, a leading provider of security software throughout Russia, Eastern and Central Europe, announced its integration of Mailshell's anti-spam engine, including the LiveFeed real-time reputation data service, into its enterprise security software and appliances. LETA selected Mailshell after extensive technical evaluation and will use Mailshell's engine to replace SpamAssassin. LETA's customers will join more than 6,000 enterprises and more than 15 million consumers who rely on "Powered by Mailshell" filters for email reputation, spam filtering and phishing detection.

LETA will incorporate Mailshell technology into its firewall solutions, available either as software or as appliances. The solution is available in three SKUs, for up to 50 users, up to 250 users and up to 1000 users. LETA's "Powered by Mailshell" filter, which also includes other security functionality including anti-virus and firewall, will launch first in Russia, Poland and Germany, followed by a US launch via channel distribution partners.

"Mailshell provided consistently higher detection rates, including protection from backscatter spam, than other solutions we tested," said Alexander Chachava, President of LETA. "Mailshell filters Russian spam more accurately than other commercial filters that either have inferior detection rates or high false positive rates with Russian email."

LETA's customers will also have access to LiveFeed, Mailshell's real-time reputation data service that uses advanced statistical models and a global data network to quantify email reputation for each message. Unlike binary 'good' or 'bad' rating systems, LiveFeed produces graduated trust ratings that automatically adjust over time as reputations change.

"LETA has built an impressive business catering to the security needs of Russian and European enterprises," said Tonny Yu, CEO of Mailshell. "The company succeeds by combining excellent technology along with superior understanding of regional enterprise requirements, expectations and buying habits."
