Make your TARA — and your CSMS evidence — hold up to UN R155 type approval.
Ansvar is a gateway for the AI assistant your team already uses — Claude, Microsoft Copilot, any MCP client. Connect it, and every answer below comes back cited to the provision or marked unresolved.

TARAthreat analysis & risk assessment
Vehicle cybersecurity grounded in the regulations and standards that gate type approval. UN R155 and R156 are addressable provision by provision, with ISO/SAE 21434 and the diagnostic standards surfaced as clause maps and Ansvar cross-references — never the standard text. Run the TARA, the CSMS gap, or an ECU effective-risk pass and cite every finding.

Questions buyers ask first
- Do you give us the ISO/SAE 21434 text?
- No. ISO/SAE 21434 and the diagnostic standards are surfaced as requirement and clause mappings with Ansvar cross-references, never the reproduced standard. UN R155 and R156 are the regulations, addressable provision by provision.
- Does this produce a type-approval verdict?
- No. The TARA and CSMS/SUMS gap analyses are decision-support — cited evidence you take into the type-approval process, not the approval itself.
