Cybersecurity for the automotive industry

Automotive suppliers and subcontractors operate within a supply chain tightly integrated with OEMs, which are imposing increasingly strict contractual security requirements. The sector combines intellectual property protection concerns, production systems security, and, for some players, embedded software security.

Sector-specific considerations

European OEMs increasingly integrate supply-chain security questionnaires into their supplier onboarding processes, within a broader regulatory context shaped by texts such as the NIS2 directive, which raises the bar on securing critical supply chains.

Engineering and design data (drawings, technical specifications, prototypes) represent a high-value asset whose compromise can have a direct competitive impact.

Production lines integrate operational technology (PLCs, supervisory systems) whose growing interconnection with IT management networks widens the exposure surface to threats.
