Threagile
Threagile
Threagile enables teams to execute Agile Threat Modeling as seamless as possible, even highly-integrated into DevSecOps environments. Threagile is the open-source toolkit which allows to model an architecture with its assets in an agile declarative fashion as a YAML file directly inside the IDE or any YAML editor. Upon execution of the Threagile toolkit a set of risk-rules execute security checks against the architecture model and create a report with potential risks and mitigation advice. Also nice-looking data-flow diagrams are automatically created as well as other output formats (Excel and JSON). The risk tracking can also happen inside the Threagile YAML model file, so that the current state of risk mitigation is reported as well. Threagile can either be run via the command-line (also a Docker container is available) or started as a REST-Server.Starting Price: Free -

DevArmor
DevArmor
DevArmor is an application security platform built for modern engineering and security teams. Instead of scanning for vulnerabilities only after code is written, DevArmor works earlier in the process — automating threat modeling and embedding secure-by-design practices directly into how teams build software. This helps organizations identify architectural and design-level risks early, where they're cheapest and easiest to fix. DevArmor is designed to fit the way engineers already work, so security becomes part of the development lifecycle rather than a bottleneck at the end. It gives security teams visibility into design risk across their applications while empowering developers to make secure decisions without needing to be security experts. With growing coverage for modern stacks — including AI-powered components — DevArmor supports AppSec, DevSecOps, and shift-left initiatives across the software development lifecycle.Starting Price: Custom Pricing -

Microsoft Threat Modeling Tool
Microsoft
Threat modeling is a core element of the Microsoft Security Development Lifecycle (SDL). It’s an engineering technique you can use to help you identify threats, attacks, vulnerabilities, and countermeasures that could affect your application. You can use threat modeling to shape your application's design, meet your company's security objectives, and reduce risk. The Microsoft Threat Modeling Tool makes threat modeling easier for all developers through a standard notation for visualizing system components, data flows, and security boundaries. It also helps threat modelers identify classes of threats they should consider based on the structure of their software design. We designed the tool with non-security experts in mind, making threat modeling easier for all developers by providing clear guidance on creating and analyzing threat models. -
