Amazon Fraud Detector
Amazon Fraud Detector is an AWS AI/ML service designed to help organizations identify and prevent online fraud more quickly. It allows developers to build models that analyze transaction data in real time, flagging suspicious activities before they cause financial loss or damage to customer trust.
You should choose this tool if you need a managed solution for fraud detection without heavy infrastructure overhead. Be aware that while the service operates on a free pricing model, a free trial is also available, which may imply usage limits or a temporary nature to the free access tier for new users.
