# Fraud & risk prevention

> Stop bots, prevent fraud, and protect your app with Device Fingerprinting and Intelligent Rate Limiting.

## Intelligent fraud prevention

Unlike basic WAF or CAPTCHA solutions, Stytch Device Fingerprinting provides intelligent fraud prevention that protects your app while maintaining a frictionless end-user experience.

* **Integrate in minutes**: Add a simple JavaScript snippet to immediately start monitoring vulnerabilities
* **99.99% accurate bot detection**: The world's most accurate device fingerprinting, leveraging standard and proprietary signals
* **Invisible to real users**: No clicking on stop signs or solving puzzles—only add friction to suspicious traffic
* **\<100ms latency**: Frictionless UX with more than 3x lower latency than competing solutions
* **Intelligent rate limiting**: Granular device, browser, and network fingerprints go beyond IP address detection
* **Tamper-resistant**: Client-side encryption prevents reverse engineering and signal spoofing
* **AI agent detection**: Monitor, allow, or restrict AI-driven activity like OpenAI's Operator and Anthropic's Computer Use
