Stop Chargeback Fraud, Card Testing & Friendly Fraud
E-commerce fraud has moved beyond stolen cards. Coordinated fraud rings use residential proxies to look like real customers until the chargebacks hit. Sentinel catches them before checkout.
What E-Commerce platforms face in 2026
Friendly fraud & chargeback rings
Coordinated groups of accounts use residential proxies to appear as unrelated customers, make purchases, then dispute them all simultaneously. Stripe Radar and IPQS see 400 different "real" users — Sentinel links them to one device cluster.
Card testing at scale
Bots test stolen card numbers with micro-transactions across your checkout flow. Each bot rotates IPs and device fingerprints — but behavioral and device signals expose the automation.
Account takeover & loyalty point theft
Credential stuffing bots take over customer accounts to steal loyalty points, gift card balances, and saved payment methods.
Promo & coupon abuse
Automated accounts claim single-use promo codes repeatedly, rotating emails, devices, and proxies to bypass per-account limits.
