The company stores a large volume of data in AWS and wants to detect if any of it is sensitive. Which AWS service helps identify sensitive data?

Amazon Macie is the correct choice because it is a data security and data privacy service that uses machine learning and pattern matching to discover, classify, and protect sensitive data in AWS. It automatically identifies sensitive data such as personally identifiable information (PII) and intellectual property stored in Amazon S3. Amazon Inspector is an automated security assessment service that helps improve the security and compliance of applications deployed on AWS, but it doesn't focus on data classification. AWS Identity and Access Management (IAM) helps manage access to AWS resources, not identify sensitive data within them. Amazon CloudWatch is a monitoring and observability service that collects data and operational metrics, but it does not classify data content.
