Fraud & Risk Prevention powered by Stytch

An advanced suite of cutting-edge fraud products that empower you to confidently identify and shape your application's traffic with the utmost accuracy. We equip you with the precise signals and controls to detect and take appropriate actions against bots, web scrapers, bad actors, new users, returning users, and more.

Multiple levels of fraud and risk prevention


Device Fingerprinting (DFP)

A set of customizable tools that collect robust device and browser identifiers with the utmost accuracy, empowering you to take well-informed actions for precise traffic shaping. Our DFP identifiers remain stable across incognito browsing, WebViews, VPNs, IP addresses, and more.

DFP Protected Authentication

A full-stack fraud solution that seamlessly integrates our Device Fingerprinting product with our frontend auth SDKs. It's a ready-made solution that enables you to focus solely on building auth flows while harnessing all the protective advantages of DFP.


A modern take on traditional CAPTCHA that thwarts bots by using device intelligence to encrypt the CAPTCHA. This ensures the CAPTCHA is solved where its shown - not by a bot, or by an outsourced service.

About Fraud & Risk Prevention

As your applications scale, you become a larger target for malicious actors trying to exploit your intended use of your application. They could attempt to steal your data via web scraping, steal your user’s data via credential stuffings, exploit expensive flows like toll fraud or LLM credentials, or abuse deals through coupon reuse. You need a strong toolset to ensure that your users are who they say they are and cannot take advantage of your application.

Designed with security as the first priority, Stytch’s anti-fraud solutions enable developers to gain insights into their application's traffic and prevent abuse by bad actors.

Fraud & Risk Prevention features

Stytch offers developers a comprehensive set of features and capabilities in order to confidently identify and appropriately handle any traffic. This includes but is not limited to:

  • Stable global identifiers: Stytch provides unique identifiers for each visitor's device, which you can leverage with granular-level controls to determine how you want to respond. Each identifier uses a different set of signals that represent a different use case allowing a wide variety of use cases.
  • Clear Action Recommendations: A Stytch fingerprint includes one of three default suggested actions — Allow, Block, and Challenge — to allow for easy and accurate decisioning. Other fraud products offer a confusing risk score from 0 to 1, and users are instructed to gauge their risk tolerance by setting a minimum score, requiring a trial-and-error process to find the right balance.
  • Tamper Resistance: Uses cryptographic signing to detect fingerprints that have been tampered with. Resistant to static and dynamic analysis reverse-engineering techniques.
  • Encryption: Encryption on Wire and at Rest. Payloads are never visible in plain text to external users. Unlike other fingerprinting products, none of the signals that we gather will be potentially exposed to bad actors which makes it significantly harder to reverse engineer.
  • TLS Fingerprinting: Proprietary TLS and network fingerprinting, performed entirely server-side to prevent tampering.
  • Strong CAPTCHA: We’ve made it architecturally impossible for a CAPTCHA provider service to easily generate solutions for sites protected by our Strong CAPTCHA product. By removing the public site key entirely from the end user’s browser environment, Strong CAPTCHA is functionally incompatible with the common attacker-preferred, easy-to-use paid API pathways used today.
