Network Inspector

Network Inspector can help identify vulnerabilities in your home 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 foreign 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.


We strongly recommend creating a strong password that is long enough and includes numbers, symbols, or capital letters. To make the password harder to crack, use a mix of different types of characters.

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

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 ICON_RADAR_VIEW. 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 network set as Private (Home) network in Windows.

You can choose from the following scanning options:

Scan everything

Scan router only

Scan devices only


Perform network scans on your home network only! If you do this on other networks, be aware of potential danger.


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 home network and a previously unseen device is now present.


Both notification types inform you if an unauthorized device is trying to connect to your network. Click View device details to show the details.

What do the icons on the devices in Network Inspector mean?


The yellow star icon indicates devices that are new to the network or detected by ESET for the first time.


The yellow caution icon indicates that your router may contain vulnerabilities. Click the icon in your product for more detailed information about the issue.


The red warning icon indicates that your router contains vulnerabilities and may be infected. Click the icon in your product for more detailed information about the issue.


The blue icon may appear when your ESET product has additional information for your router but does not require immediate attention because there are no security risks present. Click the icon in your product for more detailed information.
