Automotive Security
End-to-end cyber assurance for connected and autonomous vehicle programmes, mapped strictly to ISO/SAE 21434, UNECE WP.29, and UN R155 compliance obligations.
The Case for Automotive Security
Connected vehicles are software-defined systems carrying physical safety implications. Regulators worldwide now mandate cyber assurance as a prerequisite for type approval.
Data points generated daily by a modern connected passenger vehicle, a telemetry surface requiring active security governance

ISO 21434 Programme Delivery vs. Ad-Hoc Security Reviews
Automotive cybersecurity is not an optional enhancement. It is a type approval prerequisite in every UN/ECE member jurisdiction since July 2022, and in China and Japan through equivalent regulations. UN R155 requires a certified Cyber Security Management System (CSMS) covering the entire vehicle lifecycle from concept through post-production. Ad-hoc security reviews conducted by general-purpose penetration testers cannot satisfy this requirement because they lack the vehicle-specific threat modelling methodology, TARA, mandated by ISO/SAE 21434.
Vyomerc's automotive security practice delivers ISO/SAE 21434 TARA programmes, UN R155 CSMS establishment, secure OTA update pipeline design, CAN bus and Automotive Ethernet intrusion detection deployment, and digital twin-based attack simulation for autonomous driving software stacks. Our team understands both the engineering and regulatory dimensions, working alongside OEM product security teams as a specialist partner across the full vehicle development lifecycle.
Vyomerc Automotive Security
Ad-Hoc Security Reviews
Regulatory compliance
UN R155 CSMS establishment and ISO/SAE 21434 TARA, satisfying type approval requirements
General penetration testing cannot satisfy UN R155 CSMS or TARA requirements
Threat methodology
ISO/SAE 21434-compliant TARA with automotive-specific asset, threat, and attack feasibility analysis
Generic threat modelling not designed for vehicle architecture or safety-critical systems
Lifecycle coverage
Security integrated from concept phase through post-production and end-of-life per ISO 21434 Part 6
Periodic reviews at specific milestones only; lifecycle gaps unaddressed
OTA security
Secure OTA update pipeline design with code signing, rollback integrity, and anti-downgrade protection
OTA security typically absent from general security review scope
