The tables below show the default ports that must be open on Administration Servers and on client devices. If you want, you can change default port numbers.

The table below shows the default ports that must be open on Administration Server. However, if you install the Administration Server and the database on different devices, you must make available the necessary ports on the device where the database is located (for example, port 3306 for MySQL Server, port 1433 for Microsoft SQL Server, or port 5432 for PostgreSQL and Postgres Pro). Please refer to the DBMS documentation for the relevant information.

Please note that the klnagent process can also request free ports from the dynamic port range of an endpoint operating system. These ports are allocated to the klnagent process automatically by the operating system, so klnagent process can use some ports that are used by another software. If the klnagent process affects that software operations, change the port settings in this software, or change the default dynamic port range in your operating system to exclude the port used by the software affected.

Also take into account that recommendations on the compatibility of Kaspersky Security Center with third-party software are described for reference only and may not be applicable to new versions of third-party software. The described recommendations for configuring ports are based on the experiences of Technical Support and our best practices.

The table below shows the ports that must be open on a managed device with Network Agent installed acting as a distribution point. The listed ports must be open on the distribution point devices in addition to the ports used by Network Agents (see table above).
