Kaspersky Security for Linux Mail Server

Superior protection for your email system

Designed for integration with a variety of Linux-based mail systems, Kaspersky Security for Linux Mail Server delivers the security, flexibility and ease of management that businesses and ISPs demand. By providing a wide range of vital Linux mail server security functions – including anti-malware, anti-spam, anti-phishing and content filtering – in one easy-to-manage application that includes cloud-assisted technologies, Kaspersky Security for Linux Mail Server offers enhanced protection, while also achieving a low rate of false positives.


Better detection… improves user productivity

Kaspersky Lab’s Linux mail server security solution includes advanced spam detection technologies that help to minimise the number of spam messages that get through to your email system – so there are fewer distractions and disruptions for your users.

Because Kaspersky Security for Linux Mail Server also achieves a very low rate of false positives, your email system benefits from rigorous protection – without the inconvenience and disruptions that result from large volumes of legitimate emails being incorrectly identified as spam and being quarantined.

Cloud-assisted anti-spam & anti-phishing… deliver better protection

Kaspersky Security for Linux Mail Server incorporates Enforced Anti-Spam Updates Service (EASUS) – to reduce your email system’s ‘window of exposure’ to newly launched spam attacks. Integration with the Kaspersky Security Network (KSN) ensures your email system receives real-time information about new spam – as soon as it’s available on Kaspersky’s cloud-based database.

In addition, Kaspersky’s cloud-based Reputation Filtering technology uses sophisticated content-analysis tools to identify possible spam – and it employs cloud-assisted capabilities to ‘compare notes with other users’. As a result, you benefit from a Linux mail server security solution that processes messages with minimal latency, while it further reduces the number of false positives and increases the overall detection rate.

Kaspersky’s latest anti-phishing module also receives real-time updates from the cloud-based Kaspersky Security Network. So you benefit from improved detection that can defend your corporate email system – and your users – against emails that contain links to phishing websites.

Effective anti-malware engine and exploits detection

With our latest antivirus engine, Kaspersky Security for Linux Mail Server achieves high detection rates and faster scanning – to deliver Linux mail server antivirus capabilities that achieve rapid, accurate detection of malicious email attachments.

Kaspersky’s ZETA Shield (Zero-Day Exploit and Targeted Attack Shield) is designed to identify malware within targeted attacks. The combination of Kaspersky’s latest antivirus engine and ZETA Shield significantly boosts malware detection rates – so your business can enjoy an even higher level of protection.

High throughput and high performance

Kaspersky Security for Linux Mail Server has been designed to deliver high throughput – without significantly affecting the performance of your systems… and that helps to boost efficiency for your business.

Ease of deployment and management – saves you time and money

Powerful email traffic rules and support for OpenLDAP and Active Directory, help you to implement your corporate policies – while you also give users the ability to set up their own personal blacklists / whitelists and manage their own quarantined items… which helps to reduce the number of calls to your helpdesk.

You can integrate Kaspersky Security for Linux Mail Server’s reporting and monitoring facilities into your existing monitoring system (SNMP), or you can manage the application via Kaspersky Security Center – Kaspersky’s easy-to-use management console.

Integration eliminates hassle

Kaspersky Security for Linux Mail Server can be integrated with popular Linux-based Mail Transfer Agents (MTAs) – including Postfix, Sendmail, Exim and qmail. In addition, because the application can be integrated with Linux-based mail systems using AMaViS, it’s easy to upgrade from an open-source antivirus scanner to the rigorous protection offered by Kaspersky Security for Linux Mail Server. The application also supports IPv6.

Kaspersky Security for Linux Mail Server

Key Features

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 Lab’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.

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.

Zero-Day Exploit and Targeted Attack (ZETA) Shield
Kaspersky’s innovative ZETA Shield technology helps to defend you against unknown malware and exploits – including Zero-Day attacks, Zero-Hour attacks and Advanced Persistent Threats (APTs).

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.

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

Kaspersky Security Network
Access to the cloud-based Kaspersky Security Network lets you check on a specific, suspicious email – whenever you wish.

Improved! Attachment filtering
Kaspersky’s Format Recogniser technology filters attachments – by using real information about file type, name and message size – to help you enforce your email usage policy and address corporate liability issues that can arise if users try to distribute illegal music or video files via your email system.

Global Blacklists and Whitelists
It’s easy to create blacklists or whitelists – and manage ‘allowed’ or ‘denied’ sources, by using IPv4 and IPv6, wildcards and regular expressions.

Improved! Personal Blacklists and Whitelists
Users can easily create their own blacklists and whitelists – while accessing their personal quarantine area.

Asian language spam detection
Kaspersky Security for Linux Mail Server also includes special settings to increase the accuracy of spam detection in many Asian languages – including Japanese, Korean, Thai and Vietnamese.

Improved! Quarantine and personal quarantine – with flexible search and sorting
When Kaspersky Security for Linux Mail Server blocks email messages, it stores them in a backup. If the system uses Microsoft Active Directory or OpenLDAP, individual users can access their personal backup via the Web – so users are less likely to need to call your helpdesk.

Integration support

Integration with most popular MTAs – including Postfix, Sendmail, Exim and qmail
You can choose the method of integration, depending on your Mail Transfer Agent (MTA) – so you can integrate as a plug-in or a Milter API.

Antivirus command line file scanner
The Kaspersky Anti-Virus On-Demand Scanner allows on-demand virus checking of objects – including directories, regular files and devices such as hard drives, flash drives and DVD-ROMs.

AMaViS (A Mail Virus Scanner)
Kaspersky Security for Linux Mail Server supports integration with Linux mail systems using the high-performance AMaViS interface.

At-a-glance monitoring and flexible reporting

New! Integration with Kaspersky Security Center
Kaspersky’s easy-to-use management console, Kaspersky Security Center, gives you the ability to monitor security for all your Linux mail servers – including clusters – from a single console. If a security incident occurs, the system administrator will automatically be informed about the affected server and the cause of the issue.

New! Support for Help Desk function
Help desk specialists can now access a user’s backup and personal blacklists / whitelists – via a standard web interface, without disturbing system administrators or end users.

Improved! Dashboard
The web dashboard provides an at-a-glance view of status and monitoring, including information about the most recently found malware.

Full support for SNMP (Simple Network Management Protocol)
SNMP support lets you monitor any type of event, using SNMP events and traps.

Web and CLI management
You can choose your method of application management – using the Web console or command line interface (CLI).

Detailed, flexible reporting in PDF format
Customisable reports help you to monitor and analyse your security and policies.

Notification system
Administrators and document owners are informed about policy violation incidents – so immediate action can be taken.

Detailed logs
Detailed information about all product actions is automatically recorded – to help you to identify the cause of a problem.

Easy to install and maintain

Simple installation
Kaspersky Security for Linux Mail Server is delivered as a set of OS-specific installation packages – and a special, post-installation script makes it easy to deploy the application and integrate it with an existing mail system.

Active Directory and OpenLDAP integration
Integration helps you in setting up rules and policies. Communication between Kaspersky Security for Linux Mail Server and LDAP server can be encrypted using TLS or SSL.

Rich email traffic management rules
Kaspersky makes it easy for you to implement group-based scanning policies and rules.

IPv6 support
You can use IPv6 naming for Internet addresses, when creating traffic rules.

Scalable architecture
The entire system can be easily migrated from a test server to a production environment, so you can thoroughly test the system before you roll it out.

Simple to update
In addition to running manual updates – for the antivirus, anti-spam, anti-phishing and ZETA Shield technologies – you can also specify rules for fully automatic updates.
