Know Your User (KYU): A Critical Shift in Fraud Prevention

As fraud becomes more adaptive and AI-enabled, traditional detection methods are no longer sufficient to safeguard organizations from fast-evolving threats like synthetic identities, account takeovers, and promotion abuse. Simultaneously, the rise in digital transactions and accelerated enterprise digitalization have significantly expanded the attack surface for malicious actors. Businesses must detect fraud earlier to ensure regulatory compliance, avoid loss of revenue and trust, and more accurately to avoid compromising user experience.

Against this backdrop, Know Your User (KYU) has emerged as a critical pillar in modern fraud prevention frameworks. Unlike static identity checks, KYU continuously analyzes behavioral and contextual signals such as typing cadence, device orientation, geolocation, and mouse activity — to passively authenticate users in real time. This not only helps distinguish between genuine and fraudulent activity but also enables organizations to make risk decisions instantly, with minimal friction.
