CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Threat modeling teams building attack surface inventories should start with CAPEC because it's the only free, publicly maintained dictionary that maps adversary tactics to the specific weaknesses they exploit, not just the vulnerabilities themselves. NIST includes CAPEC as the authoritative source for attack pattern classification, and it's structured specifically for red teams and architects to enumerate realistic attack chains before code is written. Skip this if your team needs automated threat discovery or integration with your existing risk register; CAPEC is a reference library, not a scanning or correlation engine.
