Threagile
Agile Threat Modeling as Code.
Overview
Threagile is an open-source toolkit that allows teams to perform threat modeling in an agile, declarative way. Instead of a graphical UI, users define their architecture, assets, and trust boundaries in a YAML file. When executed, Threagile analyzes this model against a set of built-in and custom risk rules to automatically generate a report of potential threats, mitigations, and data flow diagrams. It's designed for developers to integrate directly into their IDE and CI/CD pipelines.
✨ Key Features
- Threat Modeling as Code (YAML-based)
- Extensible Risk Rule Engine
- Automatic generation of DFDs and reports
- Designed for Agile and DevSecOps environments
- Runs as a command-line tool or REST server
- Free and open-source
🎯 Key Differentiators
- 'Threat modeling as code' approach using YAML.
- Designed specifically for CI/CD and DevSecOps automation.
- Highly extensible with custom risk rules.
Unique Value: Threagile brings threat modeling directly into the developer's workflow as code, enabling fully automated, version-controlled, and agile security analysis within the CI/CD pipeline.
🎯 Use Cases (4)
✅ Best For
- Running threat model analysis on every code commit.
- Maintaining threat models in Git alongside application code.
- Customizing risk rules to match organizational security policies.
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Non-technical users or teams who prefer a graphical, drag-and-drop interface for modeling.
🏆 Alternatives
Unlike GUI-based tools, Threagile is designed for automation and integration, treating the threat model as another piece of source code. This makes it ideal for mature DevOps teams.
