AmazonMacieis the AWS service purpose-built todiscover and classify sensitive data in S3(PII, financial data, credentials, etc.) and produce findings that can be aggregated centrally. In a multi-account organization, the recommended centralized model is to designate adelegated administrator accountfor Macie so the security team can manage discovery across member accounts from one place.

To make the findings visible from a single location and integrate them with broader security visibility,AWS Security Hubprovides centralized aggregation of security findings across accounts and services. By also configuring the security account as thedelegated administrator for Security Hub, the company can aggregate findings across the organization. Macie integrates with Security Hub so that sensitive data discovery findings flow into Security Hub’s centralized view, giving the security team a single console and API surface to build an “inventory” of sensitive data locations and severity.

Inspector (options B and C) is focused on vulnerability management (EC2, ECR, and related scanning use cases), not sensitive data classification in S3. Trusted Advisor is not the primary destination for sensitive data discovery findings at organizational scale. Therefore, Macie + Security Hub with delegated administration in the security account is the correct solution.
