Protecting Passenger Rail Service & Safety

Passenger rail systems run under high public scrutiny and strict safety requirements. From signaling and control centers to stations and trains, cybersecurity must secure complex OT while preserving punctual operations and reliable service.

The Main Challenges in Securing Passenger Rail OT

Passenger rail OT supports continuous, time-critical service

Passenger rail operates on dense schedules with limited tolerance for disruptions, especially in urban and commuter networks. Even minor cyber incidents can cascade into service delays, crowding, and safety concerns, underscoring the need for resilience and early detection.

Operational environments extend beyond the rail network itself

Passenger rail OT increasingly interfaces with station systems, passenger information displays, ticketing integrations, and third-party services. This expanded attack surface introduces new risks while making it harder to maintain clear boundaries between operational systems and customer-facing technology.

Incidents carry immediate safety and public impact

Cybersecurity incidents in passenger rail are not just operational issues; they can affect public trust, regulatory scrutiny, and perceptions of rider safety. Response must be fast, coordinated, and conservative by design, ensuring threats are contained without disrupting service or compromising safety-critical systems.

OUR Solution

How CylusOne Empowers Security Operations in Passenger Rail

End-to-End Visibility Across Passenger Rail Systems

CylusOne provides unified visibility across passenger rail OT environments, continuously discovering assets and monitoring communications across signaling, control centers, depots, stations, and onboard networks, including station edge VLANs, onboard-to-ground links, and maintenance access paths. This shared operational view helps teams understand how systems interact across the network and identify risks before they affect service.

Rail-Specific Detection for ERTMS Environments

CylusOne applies rail-specific detection tuned to passenger operations, distinguishing between regular timetable-driven activity and anomalous behavior that could signal cyber threats. In ERTMS-based environments, this operational awareness is critical. It helps separate expected Euroradio (ETCS L2) supervision/control traffic from anomalous behavior that could affect safety or service reliability.

Response Aligned with Passenger Rail Operations

CylusOne enables coordinated, rail-safe response across security, operations, and engineering teams. By integrating into existing SOC processes via SIEM/SOAR workflows while respecting passenger rail operational constraints, it supports faster investigation and containment, helping operators protect riders, maintain schedules, and preserve public confidence.
