CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
AWS-native teams drowning in unclassified data across S3 buckets should start with Amazon Macie because it finds sensitive data at scale without requiring agents or extensive configuration. The tool integrates natively with S3 and costs nothing to pilot, making it the fastest path to baseline discovery for organizations already committed to AWS. Skip it if you need discovery across multi-cloud storage or have complex data residency rules that demand granular policy control; Macie's strength is breadth of scanning, not depth of compliance routing.
Healthcare security teams storing genomics or clinical research data in AWS need Cloud Storage Security for one reason: it scans petabyte-scale datasets without egressing data from your environment, which matters when you're handling PHI under HIPAA and HITRUST. The tool covers all major AWS storage surfaces (S3, EFS, EBS, FSx) with daily malware definition updates and audit-ready logging that satisfies 21 CFR Part 11, so compliance reporting actually works. Skip this if your data lives primarily in Azure or GCP, or if you need broader data governance beyond malware detection and PHI tagging.
