HOW IT WORKS_

Proxy Detection to prevent fraud before it starts

Fingerprint assigns a stable visitor ID and surfaces real-time proxy, VPN, and anonymizer signals. Feed these insights into your fraud prevention tools to catch risky sessions early and keep your customers protected.

See through masked network traffic with Fingerprint

Fraudsters often hide behind proxies, VPNs, and anonymizing tools, making it difficult to know who’s really visiting your site. Fingerprint assigns a stable visitor ID that stays consistent across sessions and networks and helps you spot returning devices even if they clear cookies or switch IP addresses.

FINGERPRINT'S SMART SIGNALS

REPEATED FRAUD ATTEMPTS

Virtual Machine Detection_
