Kaspersky Secure Mail Gateway
Nov 21, 2023
Kaspersky Secure Mail Gateway lets you deploy a mail gateway as a cluster system, which can scale with the volume of processed traffic, and integrate it into the existing mail infrastructure of your organization. An operating system, mail server, and Kaspersky anti-virus application are pre-installed on the mail gateway.
Kaspersky Secure Mail Gateway protects incoming and outgoing email against malicious objects, spam and phishing content, and performs content filtering of email messages.
Kaspersky Secure Mail Gateway functionality includes:
- Perform Anti-Virus scanning of messages:
- Check messages for viruses, malware, and macros (for example, Microsoft® Office files containing macros), encrypted objects, archives (including recognizing types of files inside archives and compound objects).
- Use the information from Kaspersky Security Network to ensure a faster response to new threats.
- Integrate with the Kaspersky Private Security Network (KPSN) so that organizations where Internet access is restricted by internal rules and policies can utilize the functionality of the Kaspersky Security Network (KSN).
- Integrate with the Kaspersky Anti Targeted Attack Platform (KATA) for detection of threats such as zero-day attacks, targeted attacks, and complex targeted attacks known as advanced persistent threats (APT).
- Perform Anti-Spam scanning of messages:
- Check messages for spam, probable spam, mass mail (including spoofed domain recognition and IP address reputation checking).
- Detect messages that contain Unicode spoofing. If Unicode spoofing is detected, the message is considered to be spam. The application adds the unicode_spoof tag to the X-KSMG-AntiSpam-Method message header.
- Add the X-MS-Exchange-Organization-SCL X-headers to messages, based on the scan results. The headers contain the SCL rating.
- Place messages into Anti-Spam Quarantine and manage the Anti-Spam Quarantine via the web interface.
- Perform Anti-Phishing scanning of messages.
- Scan messages for malicious or advertising links, as well as links related to legitimate software.
- Perform content filtering of messages:
- By name
- By size
- By attachment type (Kaspersky Secure Mail Gateway can determine the actual format and type of attachments regardless of file extension).
- Authenticate mail senders using SPF, DKIM, and DMARC technologies.
- Configure integration with Active Directory® to obtain information about domain users.
- Obtain information about application events:
- Logging mail traffic processing events and application events that occur during the operation of the application. The log can be filtered to search for events conveniently.
- Export events in the CSV format.
- Publish application events to a SIEM system used in your organization using the syslog protocol. Information about each application event is relayed as a separate syslog message in CEF format.
- Configure and manage the application using a web interface.
- Monitor the status of email traffic and system resources, view the lists of the latest detected threats in the web interface of the application.
- Control user access to application features using a role-based access system.
- Configure authentication using single sign-on (SSO) technology.
- Create a cluster to scale the solution (horizontally or vertically) with centralized management of all servers in the cluster using the application's web interface.
- Manage Backup:
- Save original messages that were scanned and processed by the application in Backup.
- Save messages from Backup to a file.
- Forward messages to recipients.
- Receive information about users from different domains and grant users access to personal Backup.
- Configure the personal Backup digest delivery.
- Create allowlists and denylists, which let you fine-tune the way the mail system reacts to messages from certain addresses.
- Update application databases from Kaspersky update servers and custom sources via a schedule or on demand.
- Configure email notifications:
- Notify the sender, recipients, and other addresses about objects detected in a message.
- Send notifications about application events to users.
- Add email disclaimers to outgoing and incoming messages and add warnings about insecure message
- Generate and view reports about the results of message processing and application events.
- Process email messages in accordance with rules configured for groups of senders and recipients.
- Add, modify, or delete information about domains (including local domains of the organization) and email addresses, edit Kaspersky Secure Mail Gateway settings for such domains and email addresses, and configure email routing.
- Configure MTA.
- Add, modify, and delete DKIM and TLS encryption keys.
- Receive application operation statistics via the SNMP protocol, and enable or disable forwarding of SNMP traps.
Kaspersky Secure Mail Gateway is distributed as an ISO image of a virtual machine for deployment in the VMware ESXi™ or Microsoft Hyper-V® hypervisor.
Deploying the image creates a virtual machine with a pre-installed CentOS 7.9 operating system, a mail server, and Kaspersky Secure Mail Gateway. After deploying the virtual machine, you can configure it using the Initial Configuration Wizard.
