Fraud Prevention

Overview

Fraud prevention aims to stop fraudulent activity before authorization, settlement, fulfillment, or account compromise. Controls can include identity verification, phishing-resistant authentication, transaction confirmation, limits, segregation, merchant checks, secure recovery, and resistant product workflows.

Prevention differs from detection because it changes the opportunity or makes abuse harder rather than only identifying suspicious behavior. Excessive controls can exclude legitimate users, shift fraud elsewhere, or encourage unsafe workarounds if friction is poorly targeted.

Organizations should use threat modeling, loss data, customer research, and controlled experiments to prioritize measures. Layered controls are strongest when independent failure paths are considered, outcomes are measured, and attackers cannot bypass every protection through one compromised channel.

Fraud Prevention applies controls intended to stop or reduce fraud loss before, during, or after a transaction and must measure customer and merchant friction.

Fraud prevention reduces opportunities and incentives for deception before loss occurs through product design, controls, authentication, limits, and education. A fraud alert for Fraud Prevention is a reason to investigate, not proof of intent, so decisions require explainable evidence, documented thresholds, and a fair exception path. Effective fraud prevention changes the attack opportunity while preserving legitimate use, supported by layered controls and measured customer impact.

Operational review of Fraud Prevention should reconstruct Fraud prevention reduces opportunities and incentives for deception before loss occurs through product design, controls, authentication, limits, and education using the identities, communications, devices, and transaction records available for the affected case. Investigators should separate confirmed facts from hypotheses about controls, authentication, and limits, preserve the original evidence, and document why the event was cleared, escalated, or treated as a loss. Containment, recovery, and customer communication for the Fraud Prevention context should match the harm indicated by controls, authentication, and limits.
