The assumption
Full-disk encryption protects everything on my laptop.
The reality
A thief boots from a USB drive and accesses the raw disk. With free tools they extract cached credentials, browser sessions, authentication tokens, and locally cached cloud files. Full-disk encryption protects data at rest. It does not protect data cached in temporary files, browser storage, or operating system credential managers.
With Echoron
The device holds no persistent user data. Content exists in an addressable field and is rendered in real time during authenticated sessions only. When you walk away, the device is empty. The stolen laptop is a paperweight.
