Everything in the panel below is collected on this page, in your browser, the instant it loads — and not one byte leaves it. A masked, miniature slice of what the full 1,000+ signal SDK does.
The Burein web SDK runs entirely on-device. To prove it, the panel below is the SDK — a trimmed, masked build collecting real signals from the browser you're reading this in. Open your network tab: you'll see zero requests. Move your mouse and type to watch the behavioral signals update live.
Every value in the panel was read from your actual browser — canvas and WebGL hashes, the installed-font set, timezone, and your live pointer and keystroke dynamics. Nothing is pre-recorded.
The collection script makes no network calls. Watch your network tab while you re-run it — there is nothing to see. That is the same architectural invariant the full SDK ships with.
This preview shows roughly 40 signals and runs 5 detections live. The production SDK collects 1,000+ signals and runs the full rules-plus-ML risk engine — including agentic-actor detection.
