CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams building threat models, detection rules, or red team playbooks should use MITRE ATT&CK as their taxonomy; it's the reference framework that makes threat intelligence actually actionable instead of abstract. The framework powers detection logic at organizations from startups to Fortune 500, and its 200+ tactics and techniques map cleanly to NIST CSF 2.0 Detect and Respond functions. Skip this if your team treats threat modeling as a compliance checkbox rather than an operational practice, or if you need a tool that also does risk quantification or vulnerability prioritization.
