hCaptcha Synthetic Identities is a fraud detection product designed to identify and block synthetic and cloned identities during account onboarding. The product analyzes signals from user sessions to detect fake or synthetic accounts before they can be used for malicious activity such as fraud or abuse. It provides a rules engine that lets teams build and backtest adaptive rules, enforcing responses in real time such as rate limiting, MFA challenges, or blocking suspicious applications. It includes native invisible or dynamic challenges intended to replace external CAPTCHA solutions, and native MFA using pull-based SMS and OTP authentication as an alternative to third-party MFA providers. For investigation, the product offers analytics, real-time insights, and anomaly views that let teams review the full user journey, filter suspicious sessions, and identify attack patterns. It also provides access to hCaptcha's SOC for accelerated investigation and threat analysis support. The product is part of the hCaptcha Enterprise offering and is aimed at reducing onboarding risk from fake or duplicate account creation.</description> <parameter name="summary">Detects and blocks synthetic or cloned identities during real-time account onboarding
