The record

Purpose: Dethernety is a graph-native threat modeling platform for building and analyzing architecture models.
Modeling: The platform lets users build and explore threat models visually in a browser, from code, or from reports.
Risk analysis: It analyzes attack paths, blast radius, and residual risk using the context of the full architecture graph.
Threat frameworks: Exposures map to MITRE ATT&CK techniques and controls map to D3FEND countermeasures for coverage gap analysis.
Modules: Its runtime JavaScript and TypeScript module ecosystem includes design, analysis, and issue classes, with an OPA/Rego policy engine.
Integrations: Issue modules can connect with external trackers and sync remediation issues bidirectionally.
Graph databases: The platform names Neo4j and Memgraph as graph database options, and users host their own graph database.
AI analysis: Analysis options include deterministic queries, single-agent AI acceleration, and multi-agent LangGraph workflows.
Self-hosting: The open-source edition runs on infrastructure users control and can operate fully offline without cloud calls.
Data handling: The maker says models, data, and findings stay on the user's infrastructure; optional cloud evaluations send only closed-vocabulary configuration attributes and discard the payloads.
Telemetry: The maker says the platform sends no background telemetry or usage data and contacts the cloud only when users fetch modules or request evaluations.
Availability limits: BYODt and BYODt Team are described as coming soon, while Hosted SaaS is planned for later; package composition and pricing are still being finalized.
Intended users: The maker describes the GUI for security teams and the CLI for DevOps teams, with the CLI supporting CI/CD automation and threat-model-as-code.
Support: The Enterprise edition includes dedicated support and deployment help.
Price from: Free
