Known networks

When using a computer that frequently connects to untrusted networks or networks outside of your trusted (home or office) network, we recommend verifying the network credibility of new networks you are connecting to. When networks are defined, ESET Internet Security can recognize trusted (home or office) networks using network parameters configured in Network Identification. Computers often enter networks with IP addresses similar to the trusted network. In such cases, ESET Internet Security may consider an unknown network trusted (home or office network). We recommend that you use Network authentication to avoid this type of situation. To access the known networks settings, navigate to Advanced setup (F5) > Network Protection > Basic > Known networks.

When a network adapter is connected to a network or its network settings are reconfigured, ESET Internet Security 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, the network identification configuration will create a new network connection to identify the network the next time you connect to it. The new network connection uses the protection type defined in Windows settings by default. The New Network Connection Detected dialog window will prompt you to choose between the trusted network, untrusted network or Use Windows setting protection type. If a network adapter is connected to a known network and that network is marked as a trusted 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 untrusted is used for new networks by default.

Known networks enable you to configure network name, network identification, protection type, etc. To access the Known networks editor, click Edit.


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.
