The correct answer is Macie which is a security service that uses machine learning to automatically discover, classify, and protect sensitive data stored in object storage. It is particularly suitable for healthcare organizations needing to comply with regulations such as HIPAA. This service aids in addressing compliance requirements by providing an added layer of security to sensitive data. The incorrect options include: WAF, which is primarily focused on application-level protection against common web exploits; Shield, which provides protection against Distributed Denial of Service (DDoS) attacks; and Inspector, which is designed for security assessment and does not specialize in data classification or protection.
