CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, 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.
Enterprise security architects responsible for insider threat programs and complex network access control will find real value in ConfINE's attack graph modeling, which surfaces privilege chains and lateral movement paths that standard vulnerability scanners miss. The tool maps access control properties across networked systems using formal logic, giving you forensic-grade clarity on how an attacker or insider could move from initial compromise to critical assets. Skip this if your organization lacks the security engineering depth to operationalize attack graphs or if you need real-time detection; ConfINE is a planning and investigation tool, not a monitoring platform.
