What is FraudLabs Pro?
FraudLabs Pro is a real-time fraud prevention and risk management platform for e-commerce transactions and user activity. It combines fraud scoring, configurable validation rules, IP and proxy intelligence, device signals, address and email validation, global blacklist data, machine learning and merchant feedback to identify suspicious activity and support approve, review or reject decisions.
Businesses can use FraudLabs Pro through ready-made e-commerce plugins or REST APIs, while Agent JavaScript adds device and browser intelligence for deeper screening. Account Takeover protection is also available for eligible plans to evaluate login and other user-account activity.
How does the fraud screening process work?
FraudLabs Pro evaluates submitted transaction signals, validation rules and fraud intelligence in real time, then returns a fraud score and findings that can drive approve, review or reject actions.
What signals can be analyzed?
Signals include IP and geolocation, anonymous proxies, billing and shipping data, freight-forwarder addresses, user accounts, email, phone, credit card, transaction velocity, device data, blacklists and anomalies.
