A security architecture tool. Describe your system as trust zones, components, and the data flows between them, and Mimar draws the diagram and finds the threats: the STRIDE threat register, and the weaknesses in the shape of the architecture, each with the control that fixes it. Edit the model on the left and watch it update. Nothing you type leaves your browser.
Mimar means architect. STRIDE threat modeling with zero dependencies, in the browser and as a command line tool. Source on GitHub.
