What is Automotive Cybersecurity?

Automotive cybersecurity is a dedicated domain encompassing security technologies, protocols, and solutions engineered to safeguard vehicular electronic systems, communication networks, software platforms, and onboard control units from malicious cyber threats. It supports the integrity, safety, and resilience of increasingly connected and autonomous vehicles, aligning with evolving standards like ISO/SAE 21434 and WP.29.

As vehicles transition into software-defined platforms, this market disrupts traditional automotive supply chains by embedding security at both the hardware and firmware levels. New opportunities emerge in secure OTA (over-the-air) updates, real-time threat detection, and V2X (vehicle-to-everything) encryption. These technologies make it new in architecture, easy to integrate at scale, safe for end users and regulators, and big in scope for OEMs and tiered suppliers alike. Strategic M&A, IP acquisition, and joint ventures are accelerating across the value chain.
