How CUJO Secures My Home

CUJO analyzes your local network traffic data locally and in real time. It then sends statistics on that data to the cloud for further analysis. For your privacy as well as performance reasons, we don’t send the contents of those packets to the cloud. If a threat or suspicious activity is detected, CUJO will tell the cloud what it has blocked so you can receive a notification on your mobile app to confirm it.
