CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Teams managing Microsoft 365 security across multiple workloads will find AgileBlue M365 Security worthwhile because it actually catches misconfigurations that break Exchange, Teams, and SharePoint at once instead of requiring separate tools. Continuous monitoring aligned with Microsoft and CISA baselines covers Entra ID through Power Platform, and the risk-based prioritization means you're not drowning in false positives. Skip this if your organization needs detection and response for active threats; AgileBlue prioritizes configuration drift and compliance posture, not incident hunting.
Teams automating IAM policy review in CI/CD pipelines will get real value from iam-lint because it catches overpermissioned policies before they reach AWS, not after deployment. The tool runs free as a GitHub action with configurable severity rules, making it practical for squads that want shift-left IAM governance without licensing friction. Skip this if your organization needs centralized policy enforcement across multiple cloud providers or dynamic entitlement review; iam-lint is AWS-only and static-analysis-only, best suited to developers who own their own IAM definitions.
