Known networks

When using a computer that frequently connects to public networks or networks outside of your normal home or work network, we recommend that you verify the network credibility of new networks that you are connecting to. Once networks are defined, ESET Smart Security Premium can recognize trusted (Home or office) networks using network parameters configured in Network Identification. Computers often enter networks with IP addresses that are similar to the trusted network. In such cases, ESET Smart Security Premium may consider an unknown network to be trusted (Home or office network). We recommend that you use Network authentication to avoid this type of situation.

When a network adapter is connected to a network or its network settings are reconfigured, ESET Smart Security Premium will search the known network list for a record that matches the new network. If Network identification and Network authentication (optional) match, the network will be marked connected in this interface. When no known network is found, network identification configuration will create a new network connection to identify the network the next time that you connect to it. By default, the new network connection uses the Public network protection type. The New Network Connection Detected dialog window will prompt you to choose between the Public network, Home or office network or Use Windows setting protection type. If a network adapter is connected to a known network and that network is marked as Home or office network, local subnets of the adapter will be added to the Trusted zone.

Protection type of new networks – Select which of the following options: Use Windows setting, Ask user or Mark as public is used by default for new networks.


When you select Use Windows setting a dialog will not appear and the network you are connected to will automatically be marked according to your Windows settings. This will cause certain features (for example file sharing and remote desktop) to become accessible from new networks.

Known networks can be configured manually in the Known networks editor window.
