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 auditing Azure or GCP environments with limited budgets will find Cloudmarker's open-source model valuable; you configure the rules, own the logic, and pay nothing, which beats commercial CSPM tools when compliance requirements are predictable rather than constantly shifting. The framework's GitHub presence (221 stars) and active configuration examples demonstrate real deployment use, not just marketing claims. Skip this if your organization needs multi-cloud coverage beyond Azure and GCP, or if your security team lacks the engineering bandwidth to customize detection rules rather than relying on vendor-managed baselines.
