Mail Gateway- Antivirus scanning- Spam filtering

Kaspersky Mail Gateway is a versatile solution that provides full-scale protection for mail system users against viruses and unsolicited emails (e.g., spam).

Kaspersky Mail Gateway can be installed on a separate server and does not require integration into the existing mail system. The solution significantly increases the level of protection against today’s computer threats, making it possible to combine different vendors’ antivirus solutions on the same network.

Because it is designed to operate autonomously, the application fits neatly into any environment and combines easily with other vendors’ programs installed on other network nodes. Its installation and configuration do not require extensive experience with Linux systems.

Integrated protection against viruses and spam

Antivirus scanning. The program scans for and removes all types of viruses, and malicious and potentially hostile programs in all elements of incoming and outgoing email messages, including attachments.

Spam filtering. The application scans mail traffic for spam based on formal attributes and analysis of message contents and their attachments using intelligent technologies, including special graphical signatures for detecting spam in the form of images.

User notification. If a suspicious or infected object is detected, the system administrator, sender and recipient of the message receive a notice, the contents and format of which are defined by the system’s administrator. If a message is categorized as spam, it can be blocked, sent to a quarantine folder or delivered to the recipient with a special tag in the subject field.

Quarantine. Infected and suspicious objects and messages identified as spam can be moved to a quarantine folder, where the administrator can view or delete them, or forward them to the end user.

Additional message filtering

By attachment type. The application can be configured to filter mail traffic by attachment name and file type, helping to immediately identify objects that are likely to contain viruses.

By user group. The administrator can define separate message processing rules for each group of mail system users by defining limitations in accordance with the security policy and employee needs.

Protection of the server against unauthorized access

The application can be configured to prevent DoS attacks and third party attempts to use the server for launching unauthorized mass mailings. In some cases, this helps reduce the server load and increase the processing speed of mail traffic.

Flexible management and administration

Remote administration. Kaspersky Mail Gateway can be managed remotely using a web interface, as well as traditionally, using the configuration file.

Configuration and optimization of the application. Depending upon mail traffic volume and the stringency of the company’s security policy, the administrator can change the application’s operating parameters, from maximum system performance to maximum user protection. The administrator can also configure various timeouts for sending and/or receiving messages, manage the application’s queue and limit the number of objects that can be scanned simultaneously in the background mode.

Configuration of updates. The antivirus database can be updated on demand or automatically according to a predefined schedule from Kaspersky Lab servers on the Internet or from local servers specified by the system administrator. Some modules of the antivirus engine and the linguistic analyzer can be updated, as well.

Graphical reports. The program includes the capability of viewing virus activity for a given period of time in graphical form. Information regarding the types of viruses detected during antivirus scans can also be viewed. In addition, the administrator can receive detailed information on the program’s status and operation by using a broad range of reports with the desired level of detail.
