EnCo SOX ATA vs pytm

EnCo SOX ATA is an attack tree analysis module in the SOX engineering workbench. It models hierarchical attack paths with logical AND and OR gates and links those trees to TARA threat scenarios. Users score attack steps against feasibility criteria; the module propagates scores through the tree to calculate threat or attack-feasibility levels according to the selected norm and expose critical paths. Threats can move between TARA and ATA, with paths linked by drag and drop. Reusable attack paths can be placed elsewhere in a tree or another analysis. The module connects requirements, system design, TARA and cybersecurity goals, while trace views show requirement relationships and assets can be assigned to elements. Teams can assign tasks, set statuses, track progress and review changes through a central database. Outputs include printed or image-exported diagrams, Excel results and Report Designer documentation. It runs on web and Windows; pricing is on request.

pytm is a free, open-source Python framework for creating threat models from architectural descriptions. A model is defined in Python with elements such as servers, data stores, actors, processes, data flows, and trust boundaries. From it, pytm can generate data flow diagrams, sequence diagrams, and relevant threats. Templates can produce reports with diagrams and findings, and a RevealMD template can create slides for browser presentation. Data flow diagrams use Graphviz DOT, while sequence diagrams use PlantUML. Models can be imported from JSON with pytm's Python load function. Users can supply a custom threats file and change finding attributes such as CVSS score, response text, and severity. Requirements include Python 3.11 or later, Graphviz, Java OpenJDK 10 or 11, and plantuml.jar; Linux and macOS are listed, while Windows use is documented through Devbox in WSL. The project also documents container and Devbox dependency workflows. The README warns that strings in threats.json are evaluated with eval(), so the file's permissions need protection against unauthorized changes.
