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 managing GCP infrastructure at scale who need free, auditable compliance monitoring will find Forseti Security's open source architecture worth evaluating; you get transparent scanning logic and no vendor lock-in, with 1,272 GitHub stars indicating active community validation. The tooling prioritizes infrastructure assessment over runtime detection, making it strongest for teams doing periodic compliance sweeps rather than continuous threat hunting. Skip this if you need active vendor support or expect frequent feature updates; Forseti is archived, meaning you're inheriting maintenance responsibility and won't see new detections added for emerging GCP misconfigurations.
