Cybersecurity for rail systems
Operators of rail systems face new threats, new laws, and – because of this – new cybersecurity requirements. We offer one holistic approach to cybersecurity that does not only focus on technical aspects, but also considers processes and includes internal and external stakeholders throughout the transportation system’s lifecycle.

Protecting your rail system from cyberattacks
Products and solutions
CoreShield Connect is your secure connectivity toolbox for real-time management of your rail assets. It consists of a hardware component for comprehensive connectivity and controlled monitoring of security-relevant networks and an OT Security Appliance for OT networks of railway signaling systems. An encryption unit, a Linux OS and secure remote software updates are also part of the toolbox. Additionally, you can rely on our RUGGEDCOM hardware equipment for harsh environments.
Services
Our holistic cybersecurity services include assessing existing systems, supporting continuous risk management and implementing additional mitigation and protection measures. We also offer specialized rail security training to qualify your staff in cybersecurity technologies and practices according to their specific roles and along the entire rail system’s lifecycle. We conduct awareness programs as well to highlight typical cybersecurity threats, such as phishing. For our products and solutions, we offer vulnerability advisories on a contractual basis, following the principles of managed transparency.
Supply chain and integration
Combining multi-vendor solutions into a secure, interoperable approach is complex – unless you have the right partner on hand. Our solution engineering and system integration specialists work hand in hand with cybersecurity experts, while suppliers are required to comply with strict security and quality standards. Our ProductCERT team collaborates with researchers to investigate, report, and disclose issues. Through managed transparency, we ensure that security information is shared responsibly, building trust without compromising protection.

Why Siemens Mobility as a partner for cybersecurity?

Managed security
Our products, projects, and assets are security-managed. Our trains are equipped with built-in security measures, covering the complete product lifecycle and the entire supply chain. This holistic approach to cybersecurity is implemented in the product development phase with constant and rigorous vulnerability monitoring, continuing until the train is delivered and throughout its lifecycle. We also ensure secure train connectivity for the safe transmission of data within the trains.

Proven expertise
Whether it’s rail infrastructure security or protecting rolling stock from cyberattacks, with our team of hundreds of cybersecurity experts, we can ensure the highest level of security – as we have done in many successful projects so far. We also train all our Siemens Mobility employees with awareness training, and our cybersecurity specialists with dedicated advanced training.

Integrated approach
Unlike almost any other technology company, we offer a closed range of products, solutions, and services. This makes our cybersecurity approach seamless. We are able to solve projects completely in-house without having to pass on tasks to third parties. Of course, we can also partner with external assessors when certification is needed.

Certified security
We are leading the market in security compliance. Siemens Mobility is the most certified railway vendor worldwide. The certification scheme encompasses processes and selected products and is steadily extended to meet upcoming regulatory needs. Products and processes are certified by leading institutes such as TÜV Süd and DNV.
