Checking the connection to Kaspersky Security Network

Your connection to Kaspersky Security Network may be lost for the following reasons:

• You do not participate in Kaspersky Security Network.
• Your computer is not connected to the Internet.
• Current key status does not allow connecting to Kaspersky Security Network. For example, a connection to KSN may be unavailable due to the following reasons:
  • Application is not activated.
  • License or subscription has expired.
  • License key issues have been identified (for example, the key has been added to the list of prohibited keys).

To check the connection to Kaspersky Security Network:

In the main application window, click More Tools → Kaspersky Security Network.

This opens the Kaspersky Security Network window, which displays information about Kaspersky Security Network activity. The application receives KSN usage statistics when the Kaspersky Security Network window is opened. The global statistics of the Kaspersky Security Network cloud service infrastructure and the synchronization time are not refreshed in real time.

The left part of the Kaspersky Security Network window displays one of the following statuses for the connection between the computer and Kaspersky Security Network:

• Enabled.

  This status means that Kaspersky Security Network is being used in Kaspersky Endpoint Security operations and KSN servers are available.

• Enabled. Available with restrictions.

  This status means that Kaspersky Security Network is being used in Kaspersky Endpoint Security operations and KSN servers are unavailable.

  KSN servers may be unavailable due to the following reasons:

  • The KSN Proxy service (ksnproxy) is running on the computer.
  • Firewall blocks port 13111.

  If the time that has elapsed since the last synchronization with KSN servers exceeds 15 minutes or shows the Unknown status, the status of the Kaspersky Endpoint Security connection to Kaspersky Security Network takes the Enabled value. Not available.

• Off.

  This status means that Kaspersky Security Network is not being used in Kaspersky Endpoint Security operations.

If the connection with Kaspersky Security Network servers cannot be restored, it is recommended to contact Technical Support or your service provider.
