We detected signals that correlate with fraud risk.
See how this is calculatedDevice-level truth for every visitor, checkout, and account event.
Stop bots before checkout — without adding friction for real shoppers.
Most bot detection tools rely on IP reputation and rate limits that bots route around in minutes. Fingerprint's device identity sees the same attacker across IP rotations, new accounts, and cleared cookies — so credential stuffing campaigns are flagged before the first checkout abuse hits.
Learn MoreAny browser, any device.
Identify returning web and mobile app visitors on all browsers, iOS, and Android, with exceptional accuracy.
Get details on suspicious visitors even when VPN, incognito mode, or a tampered browser or device is used.
Delight your trusted users.
Personalize user experience and reduce 2FA and OTP requirements by identifying logged-out users.
Fingerprint gives platform teams the device-level signal to stop abuse across every flow — account creation, login, checkout, and promo redemptions.
See all Case StudiesFingerprint provides clear device-level signals we can use to prevent fraud and reduce losses, while also enabling smoother customer journeys. It acts as fraud detector and a trust enabler. Leading financial services teams apply the same device intelligence philosophy — treating every interaction as a device event, not just a session.
