PRODUCTION SCENARIO
A team has collected 2 TB of support chat transcripts in an Amazon S3 bucket to fine-tune a model. Before training, the privacy office wants an automated scan of the whole bucket that reports every object containing personally identifiable information such as card numbers or addresses.
Which AWS service will meet this requirement?

Show answer and explanation
Answer: Amazon Macie
Macie discovers sensitive data in Amazon S3 using machine learning and pattern matching, covers many PII, financial, and credential types, and creates a finding for each object where it finds something. Inspector scans compute workloads for software vulnerabilities. AWS Artifact publishes AWS's own compliance reports and cannot see customer data. Amazon Comprehend can run an asynchronous PII detection job over documents in Amazon S3, but a job accepts at most 5 GB of input, far below the 2 TB in this bucket.
