France’s transportation sector blends critical infrastructure, public-facing services, and increasingly connected operational environments. Compared with many other industries, transportation security leaders have to protect safety-critical systems such as signaling, SCADA, tolling, and communications, while also securing large partner ecosystems and high-availability customer services. Cybersecurity in this sector is less about rigid control and more about resilience, operational continuity, and safe digital modernization across both IT and operational technology.
