Consultant POV

“Automotive cybersecurity went from optional to mandatory with UNECE WP.29 Regulation 155 in July 2022. Every new vehicle type approval in Europe, Japan, and Korea now requires a certified cybersecurity management system — the compliance spend alone is a multi-billion dollar market. The structural threat is clear: software-defined vehicles with OTA update capability are remotely accessible computers on wheels, and a fleet-scale vulnerability in a popular OEM platform is a national security incident waiting to happen. The most interesting commercial opportunity is the automotive SOC — Upstream Security and Argus have proven that connected vehicle fleet telemetry contains detectable attack signatures, and the OEM that centralises cybersecurity monitoring gains both compliance coverage and genuine threat intelligence.”
