Fraud Detection & Prevention — The Fraud Defense Stack

A hands-on mid-level course that stops account and payment fraud without blocking real users. Work the fraud defense stack - eight layers: Signals, Identity, Device, Behaviour, Rules, Models, Review, and Feedback - combining signals into risk decisions and tuning to catch fraud with low friction. Strictly defensive. Four hands-on activities in every lesson.

What you'll learn

• Collect the signals that separate fraud from legitimate activity.
• Verify identity and device and score behaviour for risk.
• Combine rules and models into explainable fraud decisions.
• Run manual review and feedback loops that keep models sharp.
