Fing is a nice app that runs on your smartphone or tablet that will show you who else is on your network. It puts a nice interface on capabilities like Ping, Traceroute and many others and presents information in a way that is fast. You can find links to download the app at Fing.io, and I really recommend it to everyone who has a device. Next time you decide to join a public WiFi network at a conference or hotel you can launch Fing and see how they have configured the network and if you can see others on the net. Note: The Fing app works much better on Android, for now. Apple has restricted the ability of applications to see some technical info (specifically MAC addresses). But the greatest functionality of the app is its connectivity to the device mentioned below, the FingBox. So don't let the lack of ability to scan MAC addresses deter you from downloading the app.
Fing now has something that makes it far more powerful than just an app on your mobile device. They offer a device for your home network called the Fingbox. This adds network security and troubleshooting to watch over your network and give you control to block users you don't want in your net. It detects intruders, manages devices authorized to use your network and also analyzes the quality of your WiFI and Internet connections. Fingbox also gives you parental controls.
Another really neat thing it will do is give you a "WiFi Fence" around your home. This of this like having a magic super power. You can set it to give you alerts when any device comes near your home. Imagine getting an alert when the mailman approaches or when the pizza delivery guy gets near. Imagine getting an alert when a bad guy comes close at night. Or would you like to know when a WiFi enabled drone is within range of your house?
I love the Fingbox and mostly highly recommend it to anyone with WiFi at home. Find it here.
