It seems a nice and simple tool to show me devices that connect to my router.
I'd like to know, can WiFi Guard protect me when I'm using a public Wi-Fi?
The purpose of WiFi Guard is to alert you when your own network might have been compromised. WiFi Guard periodically scans your network and reports if it has found a device that wasn't there before.
It does not make sense to use it in a public network as normally there are many other users connected to it, and you probably don't want to be alerted about them.
