An online retailer stores order summaries in Amazon S3 that sometimes include customer PII. The data engineer must detect PII so the retailer can redact it. Which AWS service provides PII detection with the least operational overhead?

Amazon Macie is the correct choice because it is a fully managed data security and data privacy service that uses machine learning and pattern matching to discover, classify, and protect sensitive data in AWS. It automatically detects PII in S3 buckets with minimal operational overhead. Amazon Textract is designed for extracting text and data from documents, not for PII detection across S3 objects. Amazon S3 Storage Lens provides insights into S3 storage usage and activity, but it does not detect PII. Amazon SageMaker Data Wrangler is used for data preparation and feature engineering for machine learning, not for automated PII detection in raw S3 data.
