Cylus and PROSE join forces to strengthen rail cybersecurity

PROSE has entered a partnership with Cylus, a global leader in rail cybersecurity. Together we aim to support rail operators and manufacturers in managing the growing cybersecurity demands placed on modern rail systems.

Railway operations are becoming more complex, and the need for secure and reliable digital infrastructure continues to increase. The partnership combines Cylus’s experience in rail-specific cybersecurity with PROSE’s long-standing engineering and consulting expertise. This includes our work across safety, security, and vehicle authorisation, as well as our broad support throughout the full lifecycle of rolling stock.

Omar Benjumea, Field CISO and Business Development Manager at Cylus, said, “We are thrilled about the collaboration between Cylus and PROSE. Together, we can drive innovation and strengthen rail cybersecurity, ensuring a safer and more resilient rail network for the future.”

Claudius Multmeier, Cybersecurity Expert – Rail at PROSE, said: “The combination of Cylus’s extensive experience in protecting railway assets from Cyber threats and PROSE’s proven 40+ years track record of solving complex questions throughout the sector will ensure a powerful and meaningful partnership for the needs of rolling stock operators and manufacturers alike.” PROSE is renowned for supporting rail projects across phases, from strategy, vehicle design, to fleet management modernisation and optimisation.

This partnership allows the two companies to leverage their combined expertise to safeguard rail infrastructure while promoting collaboration across the industry. By joining forces, Cylus and PROSE are setting a new standard for cybersecurity in rail, building a foundation of trust and resilience to ensure the safety and reliability of rail transportation systems worldwide.

Together, we are dedicated to supporting rail operators in meeting today’s challenges and confidently preparing for the future.

Bid management for regional train maintenance contracts

Customer: EuroMaint Sweden

Project tasks

  • Bid coordination
  • Development of maintenance strategy
  • Depot and resource planning
  • Technical documentation
  • Obsolescence and component lifecycle analysis
  • Cross-functional team leadership

Our approach

PROSE acted as Bid Leader, and coordinated a cross-functional team consisting of engineering, procurement, and production experts. The team jointly developed technical and operational documentation, including maintenance plans, depot strategies, and component handling procedures. The work was carried out in close collaboration with stakeholders to ensure alignment with operational needs and regulatory requirements. The documentation was structured to support both strategic decision-making and practical implementation within the bid.

Customer benefit

By selecting PROSE as a partner, the customer gained access to structured and well-documented maintenance solutions tailored to the specific fleet and operational context. The collaborative approach ensured that procurement and production perspectives were integrated early in the process, reducing risk and improving feasibility. The final documentation supported the customer’s ability to submit competitive and technically sound bids, with clear strategies for lifecycle cost control and fleet availability.
The customer also benefited from PROSE’s independent expertise, broad rolling stock knowledge, and ability to deliver practical and implementation-ready material.

Coupler upgrade and electrical interface integration

Customer: MTR Tech AB, Sweden

Project tasks

  • Requirements capture and definition of electrical interface
  • Design review
  • Update of technical documentation
  • Verification of electrical connections and signal integrity
  • Official drawing release and configuration control
  • Coordination with MTR during implementation and validation

Our approach

PROSE contributed to the design definition of the new electrical interface and collaborated closely with MTR engineers during system implementation of the upgraded coupling system be-tween the Snowblower Wagon Type B257 and the C20 train.
While MTR carried out on-site installation and testing, we re-viewed, clarified, and consolidated the draft electrical updates and ensured that all connections and signal interfaces complied with safety and operational requirements.
The verified and approved information was issued as official electrical drawings, released under PROSE authorship and re-viewed by MTR engineers.
This cooperative approach ensured full traceability, correctness, and compliance with railway documentation standards.

Customer benefit

​The customer gained a reliable and standardised coupling solution that reduced manual work in demanding winter conditions. The upgraded interface improved operational efficiency by ensuring full mechanical and electrical com-patibility between the snowblower wagon and the C20 fleet. Independent engineering review by PROSE ensured high quality and compliant documentation, providing confi-dence in the safety and integrity of the system. The result is a future-ready solution that supports safe, efficient, and well-documented winter operations.
