Empowering developers to solve fraud at the source

As opposed to top-down, enterprise-focused fraud prevention platforms, FingerprintJS prevents digital fraud by uniquely and accurately identifying users, and empowering technical teams to use that data in a way that works for their applications.

Why FingerprintJS is different

Unparalleled accuracy

Address fraudulent behavior at the source rather than through complex mitigation strategies later with a highly accurate visitorID. FingerprintJS uses an innovative combination of browser fingerprinting, IP/URL analysis, device analysis, and machine learning to accurately identify up to 99.5% of unique visitors.

Targeted authentication

Introducing unnecessary hurdles to account login and payment can be detrimental to user experience. Using our API, you can identify when you need to introduce additional authentication, keeping your trusted customers' experience streamlined.

GDPR and CCPA compliant

We take online privacy seriously. FingerprintJS is intended for fraud detection only - for this use case, no visitor consent is required for compliancy with GDPR and CGPA. We never automatically track traffic, and never do cross-domain tracking.

Committed to open source

Our team is committed to democratizing fraud prevention by keeping our core fingerprinting libraries open-source and free.

The power of fingerprinting

Fingerprinting technology is the backbone of most major fraud detection solutions. Fingerprinting identifies unique visitors and associated sessions, undeterred by incognito browsing, VPNs, cookie blockers, and other technologies used to anonymize fraudulent actors online. The technology works by analyzing data passed by the visitor's browser, device, patterns of use, and more to generate a unique visitorID that can associate patterns of fraud with specific visitors.
