Network Inspector

Network Inspector can help identify vulnerabilities in your trusted (home or office) network (for example, open ports or a weak router password). It also provides a list of connected devices, categorized by device type (for example, printer, router, mobile device, etc.) to show you what is connected to your network (for example, game console, IoT, or other smart home devices).

Network Inspector helps you identify a router's vulnerabilities and increases your level of protection when connected to a network.

Network Inspector does not reconfigure your router for you. You will make the changes yourself using your router's specialized interface. Home routers can be highly vulnerable to malware used to launch distributed denial-of-service attacks (DDoS). If the router password has not been changed from the default by the user, it is easy for hackers to guess and then log in to your router and reconfigure it or compromise your network.

If the network you are connected to is configured as trusted, you can mark the network as "My Network". Click Mark as "My Network" to add a My Network tag to the network. This tag will be shown next to the network throughout the ESET Internet Security for better identification and security overview. Click Unmark as "My Network" to remove the tag.

Each device that is connected to your network is displayed with basic information in a list view. Click the specific device to edit the device or view detailed information about the device.

In the list view, the Networks drop-down menu enables you to filter devices based on the following criteria:

•Devices connected to a specific network

•Devices connected to All networks

•Uncategorized devices

To display all connected devices in a sonar view, click the sonar icon . Move your cursor over a device icon to view basic information such as network name and date last seen.

Click the device icon to edit the device or view detailed information about the device. Recently connected devices are shown closer to the router so that you can easily spot them.

Click Scan your network to manually perform a scan of the network you are currently connected to. Scan your network is available only for a trusted network. See Network connection profiles to review or edit your network settings.

You can choose from the following scanning options:

•Scan everything

•Scan router only

•Scan devices only

When the scan is complete, a notification with a link to basic information about the device will be shown, or you can double-click the suspicious device in the list or sonar view. Click Troubleshoot to see recently blocked communications. More information about Firewall troubleshooting.

There are two types of notifications displayed by the Network Inspector module:

•New device connected to the network—displayed if a previously unseen device connects to the network while the user is connected.

•New network device found—displayed if you reconnect to your trusted network and a previously unseen device is now present.
