Product Highlights

Zero-day, Exploits and Targeted Attacks Shield (ZETA Shield)

Today, targeted attacks on companies are one of the most dangerous threats to businesses. Perpetrators often resort to distributing messages with malicious attachments, including exploits – malicious objects that use system or application errors to infect a machine.

Thanks to its innovative ZETA Shield technology, Kaspersky Linux Mail Security is able to detect and block emails containing malicious exploits, including new and unknown ones.

Enforced Anti-Spam Updates Service (EASUS)

One distinct feature of spam-related cybercrime is the “hit and run” nature of most attacks: roughly half of any spam assault is delivered inside the first 10 minutes. The new EASUS technology delivers the most important parts of every anti-spam database update in real time, so Kaspersky Security for Linux Mail Server is able to react to new spam quickly and efficiently.

Content Reputation Filtering

Content Reputation Filtering, a new Kaspersky Lab technology, fragments email content, then analyses and compares these fragments with known samples of unwanted email using Kaspersky Lab’s cloud technologies. As well as increasing the detection level of new spam and malicious messages, Content Reputation Filtering reduces the number of false positives.

Flexible Licensing

Depending on its needs, a company can choose one of three licenses for Kaspersky Security for Linux Mail Server. The first option includes anti-spam security, the second offers anti-malware protection and the third license provides complex mail server security against active cyber-threats.

Test Results

In September 2012, the Virus Bulletin magazine conducted a comparative test of corporate anti-spam solutions – the Virus Bulletin Anti-Spam Comparative Review. While scanning a collection of unsolicited mail samples collected by the Virus Bulletin experts, Kaspersky Security for Linux Mail Server detected 99.93% of spam messages, taking second place in the overall rating and first place among those corporate solutions combining cloud and local mail scanning technologies.
