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).
You can configure Network Inspector in Advanced setup > Protections > Network access protection > Network Inspector.
Enable Network Inspector—Network Inspector helps identify vulnerabilities in the network, such as open ports or a weak router password, and provides a list of connected devices, categorized by device type.
Notify about newly discovered network devices—Notifies you when a new device is detected on your network.
