Threatmodeling Tool to outgrow spreadsheets, word and MS-TMT
by Rana_KV·Feb 22, 2026·2 points·0 comments
AI Analysis
●●SolidSolve My ProblemCozy
Removes spreadsheet friction from threat modeling, but lighter than MS Threat Modeling Tool.
Strengths
- •DFD + threat + risk in a single workflow beats disconnected Word docs and spreadsheets
- •Custom risk matrices per project is genuinely useful for real teams
- •Browser-native + optional collaboration addresses real adoption pain
Weaknesses
- •Competes against established tools (MS TMT, IriusRisk, Threat Dragon) with no claimed advantages
- •No evidence of team collaboration or import/export from existing models
Category
Target Audience
Security engineers, threat modeling practitioners, DevSecOps teams

Post Description
Built a threat modeling app with architecture diagrams, threat/evaluation workflows, and risk report exports. This is meant to redefine the threat modeling experience.
Still improving it and very open to blunt feedback on usability, security, and what’s missing for real team workflows.

10-min AI threat model (STRIDE and MAESTRO), assumption-driven
Maps AI-specific threats (including MAESTRO/agentic risks) to STRIDE and spits out a concise PDF with data flows, a 5x5 risk matrix, and compliance pointers — useful for teams that need a fast, documented starting point. The smart part is surfacing and labeling assumptions so reviewers can correct the model; what's missing is transparency about how those assumptions affect risk scores and integrations (editable diagrams, CI/CD hooks, or sample reports would sell it).
