Stronger Security for
Smarter Transactions

Fraud prevention in online payments refers to the strategies, tools, and processes used to detect and prevent unauthorized or deceptive transaction attempts before they are authorized. It ensures that transactions are legitimate, protecting both merchants and customers from chargeback costs and security breaches.

Real-time transaction monitoring continuously inspects payment traffic as it occurs. The engine evaluates details such as card data velocity, device fingerprints, geolocations, and behavioral analytics. Within milliseconds, it detects anomalies and flags or blocks high-risk transactions before they go through.

3D Secure adds an extra verification step (like biometric approval or OTP) for the cardholder. This significantly reduces checkout fraud, satisfies PSD2 strong customer authentication (SCA) regulations, and transfers chargeback liability from the merchant to the cardholder's bank.

Chargeback prevention helps you identify and resolve payment disputes early. By integrating dispute detection services, the system flags problematic transactions so you can issue direct refunds or clear up misunderstandings with the card issuer before they become official chargebacks, saving you high processor fees and penalty fees.

Luup is fully compliant with PCI DSS Level 1—the highest security protocol in the payment card industry. We use advanced tokenization, secure transport layer encryption, and rigorous infrastructure access controls to protect all cardholder credentials.

Luup achieves this using intelligent, data-driven scoring parameters. Rather than applying broad blocks that reject good customers, our system dynamically routes suspicious transactions to step-up authentication (like 3DS) while allowing safe transactions to proceed seamlessly, optimizing your conversion rates.

A single authentication check can be bypassed. Multi-layer security combines multiple independent checks—such as AVS (address verification), CVV validation, device fingerprinting, risk scoring, and 3D Secure—making it exponentially harder for fraudsters to execute successful attacks.

Luup defends against card testing (validate-attacks), clean fraud (using stolen cards with correct detail parameters), friendly fraud (malicious chargebacks from real buyers), account takeover fraud, and international card schemes.

Yes. When scaling globally, you encounter different regional fraud profiles, card brands, and payment behaviors. Luup’s localized risk rule engine adjusts check parameters by country and processor to ensure safe, cross-border payments with high local approval rates.

Integration is effortless. Luup's fraud prevention engine is built directly into our unified API and checkout widgets. Once you connect to our payment infrastructure, the monitoring system operates automatically, allowing you to configure and manage rules from your merchant dashboard.
