Checkout Bot Defense: Behavioral Risk Scoring

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 3D behavioral feature space — request-velocity anomaly, interaction-entropy deficit and device/network anomaly — and scores it against two adjustable risk thresholds rendered as literal decision planes. 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, the same trade-off real fraud and bot-management teams tune in production.
