Higher-trust checkout decisions, fewer 3DS step-ups for the right users, and explicit threat evidence for the wrong ones.
Burein lets you reduce both, by basing the decision on a richer, locally-computed picture of the device, not on the IP and a few JS variables.
A stable visitor_id + zero threats + matching device profile = you can skip step-up auth for returning legitimate users, even from new IPs.
Anti-detect browsers, agent-driven checkouts, virtualized mobile clients, and screen-share scams — all visible to the risk engine without you needing to send a packet anywhere.
Anti-detect browser, residential-proxy-class network heuristic, headless tells, and a fresh storage profile on every request.
Visitor ID change mid-session, behavioral entropy break, new device identity, fresh storage.
Virtualized app host, repackaged binary, mock location, sensor tampering — all on the same device that's testing 100 BINs in a minute.
browser-use or Operator driving a return flow at scale across stolen accounts. Detected by cadence and stack, not by IP.
