Automotive Product Cybersecurity: ISO 21434, UN-R155/R156 and EU Cyber Resilience Act Compliance Support

OTCengineering provides product cybersecurity engineering for the connected vehicle lifecycle, with a focus on the regulatory frameworks now driving automotive programs: ISO/SAE 21434, UN Regulations R155 and R156, and the EU Cyber Resilience Act.

Our work covers the full chain: TARA (Threat Analysis and Risk Assessment), security concept and requirements definition, secure development support, vulnerability and incident management, and the documentation and process evidence needed for type approval and continued post-production compliance.

We engage as an agile partner that integrates into existing engineering organizations — not as a large consultancy. This is particularly relevant for Tier-1s and OEMs that need to move regulatory compliance from a documentation exercise into a working engineering practice, on real programs, with real deadlines.
