We used it for an Academy project and we also used it for a credit card transaction fraud detection project. The purpose of the project was to denote anomalies or customer records that were different from usual.

The reason that we used this solution was that it was the only end-to-end framework available on the market at that time. If I were to build my own solution on AWS, I would have had to bring in all the components, but AWS Fraud Detector has the capability to blend in not just the data streaming part, but also the multi-building part, ultimately chiming in with Amazon QuickSight for the visualization and Amazon SNS for notification.
