The assumption
I set up the Wi-Fi password and parental controls. We are safe.
The reality
Your smart TV, doorbell, thermostat, and speaker stream data to cloud servers twenty-four hours a day, not just when you are using them. Several send ambient audio to analytics servers. Your kids' tablets run apps with advertising SDKs tracking location, contacts, and usage. Your router treats this as normal traffic because it is. The devices are doing exactly what their firmware says.
With Echoron
Edge on your router inspects every packet as it crosses the network. It distinguishes between data you asked the device to send and data it is sending without your knowledge. Privacy Map shows you exactly where every byte is going, in real time. You decide what is allowed.
