CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
AppSec teams with Python-heavy codebases will get the most from pytm because it embeds threat modeling directly into the development workflow instead of treating it as a separate security gate. The framework generates threat models from code as developers commit, catching architectural risks before they reach review; 9,000 GitHub stars signal real adoption among engineering teams that actually use it. Skip pytm if your threat modeling needs include non-Python services or if you lack engineering bandwidth to integrate code-first tooling; this is a developer-first tool, not a security-first one.

Skip this if your team needs hands-on tooling with automated threat enumeration and management; this is guidance and methodology, not software that runs scans or maintains a living threat register.
