Side-by-side comparison of AI visibility scores, market position, and capabilities
Fingerprint is a device intelligence platform providing highly accurate visitor identification and fraud signals for account security and fraud prevention.
About
Fingerprint is a device intelligence platform that generates highly accurate and stable visitor identifiers by combining browser fingerprinting, hardware signals, network characteristics, and behavioral data into a persistent identifier that recognizes returning visitors — including incognito mode users, VPN users, and those who have cleared cookies — with accuracy that far exceeds cookie-based identification. The platform's core capability, VisitorID, provides web and mobile applications with a device-level identifier that persists across sessions, enabling fraud and security teams to link activity across account registrations, login attempts, and transactions to detect patterns that indicate account takeover, credential stuffing, bot attacks, and payment fraud. Fingerprint was formerly known as FingerprintJS and maintains the open-source library alongside its commercial platform.
