CAPEC is a free threat modeling tool. GuidePoint Security Application Threat Modeling is a commercial threat modeling tool by GuidePoint Security. Compare features, ratings, integrations, and community reviews side by side to find the best threat modeling fit for your security stack.
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.
GuidePoint Security Application Threat Modeling
Development and security leaders building applications from scratch or redesigning existing ones should use GuidePoint Security Application Threat Modeling when you need threat models that actually influence architecture decisions, not checkbox compliance artifacts. The expert-led whiteboarding sessions with your stakeholders produce STRIDE-aligned threat catalogs and attack trees specific to your data flows, which directly supports NIST ID.RA risk assessment before code reaches production. Skip this if your team has mature internal threat modeling expertise or you're looking for continuous, automated scanning of running applications; GuidePoint is a project engagement, not a monitoring tool.
