PyTM
A Pythonic framework for threat modeling.
Overview
PyTM (Pythonic Threat Modeling) is an OWASP flagship project that allows you to define a threat model using Python code. This 'threat modeling as code' approach enables you to version control your threat models, integrate them into CI/CD pipelines, and automate parts of the security analysis. Users define elements, data flows, and trust boundaries in Python objects, and PyTM can then generate reports and diagrams.
✨ Key Features
- Threat modeling as Python code
- Generates reports in various formats (Markdown, JSON)
- Creates sequence diagrams and data flow diagrams
- Integrates with testing frameworks like pytest
- Free and open-source
🎯 Key Differentiators
- Uses Python, a widely-known language, for defining models.
- Leverages the existing Python ecosystem, including testing frameworks.
- OWASP flagship project status.
Unique Value: PyTM allows developers to define, version, and automate their threat models using the familiarity and power of Python code, seamlessly integrating security into their development practices.
🎯 Use Cases (4)
✅ Best For
- Defining a threat model in a Python project and having it automatically updated and validated in the CI pipeline.
- Storing threat models in Git alongside the application code.
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Non-developers or those who require a graphical user interface for creating threat models.
🏆 Alternatives
Similar to Threagile, but uses Python instead of YAML, which can be more powerful and flexible for developers already comfortable with the language. It is less opinionated than Threagile's rule-based system.
💻 Platforms
