Checkout Bot Defense: Behavioral Risk Scoring (2D)

E-commerce checkout flows are under constant pressure from credential-stuffing bots, carding attempts and scalper scripts hiding among real shoppers. This simulator renders every incoming session as a point in a behavioral feature space — request-velocity anomaly, interaction-entropy deficit and device/network anomaly — and scores it against two adjustable risk thresholds rendered as literal tilted decision planes, all drawn on a single 2D canvas with a hand-written rotation projection you can drag to orbit. Tune the bot traffic share and how well the bots mimic human behavior, then watch the bot-catch rate and human-friction rate respond live on the rolling chart, the same trade-off real fraud and bot-management teams tune in production.
