How Exactly Does Cujo Protect Your Smart Home?

CUJO continually analyzes your local network traffic data in real time and then sends statistics on that data to the cloud for further analysis. It does this by scanning metadata packets coming into and leaving your local network, but to keep your privacy intact, Cujo doesn’t send the packet contents to their cloud. They also send you a notification on your app if they’ve blocked an attempted attack.
