KasperskyLinux Mail Server Security

Designed for integration with a variety of Linux-based mail systems, Kaspersky Security for Linux Mail Server delivers security, flexibility and ease of management in a single application that includes cloud-assisted technologies.

Kaspersky Security 8 for Linux Mail Server provides next-generation email protection from known and unknown threats, including spam, phishing and malicious attachments. This is accomplished by multiple layers of machine learning-powered security, including multi-factor heuristic, sandboxing and reputation system for emails and attachments, which also achieves an extremely low rate of false positives.

  • Multi-layered anti-malware capabilities

    • Improved! Advanced antivirus engine – cloud-assisted via the Kaspersky Security Network

      Kaspersky Security for Linux Mail Server includes the latest version of Kaspersky’s award-winning anti-malware engine. Furthermore, it receives real-time information from the cloud-based Kaspersky Security Network (KSN) – so you benefit from a Linux mail server antivirus solution that delivers even better performance in detecting and removing malicious attachments from incoming emails including exploits, unknown and advanced malware.

    • New! Web malicious URL filter – cloud-assisted via the Kaspersky Security Network

      With real-time updates from the cloud, Kaspersky’s Web malicious URL filter blocks emails that include links to infected sites or malicious files.

    • Detection of malicious macros/ActiveX controls in Office files

      Embedding malicious scripts into Office files is a popular technique used by extremely dangerous specimen such as ExPetr / Petya / NotPetya. Kaspersky’s next-generation anti-malware provides effective protection against such threats.

    Anti-spam and content filtering

    • Improved! Anti-spam engine

      Kaspersky’s anti-spam engine includes two powerful technologies:

      Enforced Anti-Spam Updates Service (EASUS) – which uses push technology, directly from the cloud-based Kaspersky Security Network, to deliver real-time updates. By reducing the ‘update window’ from 20 minutes to less than 1 minute, EASUS helps to protect against Zero-Hour spam and spam epidemics.

      Cloud-assisted Reputation Filtering – can ‘rate’ suspicious emails, place them in quarantine and then recheck them when updated information becomes available. This helps to defend you against unknown spam – while also reducing the number of false positives.

    • New! Cloud-assisted anti-phishing

      Kaspersky’s new anti-phishing module receives real-time updates from the cloud-based Kaspersky Security Network – for more effective detection and blocking of emails that contain links to phishing websites.

      You can easily set policies to block unwanted mass mail from reaching your end users.

    • New! Anti-spam quarantine

      Suspicious messages are placed in the anti-spam quarantine, managed from the web interface. These messages can be reviewed later.

    • New! Spam Confidence Level rating

    • Improved character support

      Supports internationalized (non-Latin) characters in email addresses.

    • New! Unicode domain spoofing detection

      Kaspersky Security 8 for Linux Mail Server now detects messages containing Unicode spoofing, which uses Unicode symbols visually resembling proper characters used in legitimate mail addresses and URLs.

      Suspicious messages are placed in the KATA quarantine, managed from the web interface.
