What Is Amazon Macie?
Amazon Macie is a fully-managed data classification service that helps monitor your information. It uses machine learning technology to continuously analyze and classify content in Amazon Simple Storage Service (S3) buckets.
After you activate Macie, the service starts scanning the contents of your S3 buckets. The initial scan helps establish a baseline of the data, including details on who accesses the data and with which protocols. Next, Macie inspects any request to access the data and provides visualizations on the dashboard.
