The assumption
My antivirus and the Wi-Fi password protect me.
The reality
Every time you connect to public Wi-Fi, your device broadcasts your laptop name, MAC address, and DNS queries to every other device on that network. Anyone with free tools can watch every site you visit in real time. Your antivirus does nothing about this because this is not malware. This is how Wi-Fi works.
With Echoron
Session identifiers are dissolved at the session level. Your device stops broadcasting the information entirely. Metadata is removed, not masked. Your connection moves across independent resolution points so your real session is never exposed.
