What stopping fraud
actually looks like

Six anonymized cases from teams running Sentinel in production — across e-commerce, fintech, SaaS, iGaming, travel, and creator platforms. Company names withheld. Each one: the attack, the signal that caught it, and the numbers after.

Behavioral Signals

Velocity patterns, device clustering, session anomalies, account linkage graphs, superhuman timing

Stolen card rings tested thousands of cards through checkout. Chargebacks hit 2.3%. Sentinel's device fingerprint and proxy signals flagged the pattern in the first transaction — not the third.

1,400 fake IBAN accounts created in 72 hours using VPNs and antidetect browsers. Sentinel's bot detection and network layer stopped 97% before KYC was even triggered.

320 accounts were running perpetual free trials by rotating browser profiles and IPs. Sentinel linked them via canvas fingerprint and device clustering — not email or IP alone.

Creator Funding Platform

A coordinated ring inflated pledge counts using residential proxies. Sentinel identified the shared ASN backbone across 800+ accounts and collapsed the ring in hours.

Professional bonus hunters ran Dolphin Anty and residential proxies to create multi-accounting rings. Sentinel's antidetect detection caught the spoofed profiles the KYC layer never saw.
