Sardine Fraud Prevention is an identity verification and fraud prevention platform designed to detect and prevent identity fraud, account takeovers, and scams. The platform combines device intelligence, behavior biometrics, and network analysis to identify fraudulent activities. The system detects synthetic or stolen identities, mobile emulators, virtual machines, and GenAI impersonation attempts. It analyzes user behavior patterns to identify bot-like activities, expert mouse movements, and suspicious account changes. The platform uses network graph analysis to uncover duplicate accounts, fraud ring connections, and users with fraudulent chargeback histories. Sardine provides customer due diligence (CDD) and enhanced due diligence (EDD) capabilities, including KYC, KYB, document verification, and behavior biometrics. The platform integrates data from over 35 providers covering phone, email, SSN, telco, and banking transaction information. It performs watchlist screening for sanctions, Politically Exposed Persons (PEP), Specially Designated Nationals (SDN), and adverse media. The platform collects signals across multiple dimensions including device identifiers, browser data, IP addresses, geolocation, typing speed, mouse movements, phone carrier information, email activity, card data, banking transaction history, blockchain data, and consortium intelligence from over 2.3 billion profiled devices. Additional capabilities include bank account validation, progressive KYC onboarding with custom waterfall flows, and real-time risk assessment through network queries.
