Cybersecurity
Monday, July 21, 2025
Cybersecurity is now a major concern for businesses and critical infrastructures. Our Cybersecurity range is designed to prevent cyberattacks, protect sensitive data, and ensure business continuity. In a world where technology is omnipresent, digital threats are multiplying, making cybersecurity essential.
One of the key technologies we integrate is the Data Diode (or DTD), a unidirectional communication device that enables the secure transfer of data between two domains with different security levels. It establishes a physical barrier that prevents any data flow in one direction while allowing a secure flow in the other.
Whether in transportation, industry, or services, robust cybersecurity—including solutions like the DTD—is a guarantee of trust, safety, and performance. Discover our solutions to strengthen the resilience of your systems against cyber threats.
In an increasingly connected world, cybersecurity has become an essential pillar for the reliability and safety of industrial systems.
At LEROY Automation, we view cybersecurity not as an option, but as a fundamental commitment: to provide our customers with secure, sustainable solutions that comply with international standards.
“Secure by design” – security built into the design of our products and processes from the outset.
Our approach is based on a complete vision of cybersecurity, which includes:
Compliance and certification with international standards.
Secure development practices at every stage of the product lifecycle.
“Cyber Ready” products and architectures that meet our customers’ needs.
Secure, certified, and controlled industrial production.
Continuous regulatory and technical monitoring to support our partners over the long term.
We are committed to compliance and continuous improvement based on the main industry standards:
IEC 62443-4-1: secure development of industrial products
IEC 62443-3-3 / TS 50701 / IEC 63452: security requirements applicable to railway systems
ISO 27001 / NIS2: information security and risk management in our production processes
Cyber Resilience Act (CRA): proactive compliance with European regulatory requirements
These certifications ensure that every LEROY Automation product and process is designed, developed, and maintained according to the highest security standards.
Security is integrated from the very design of our products and software architectures.
Our teams apply recognized practices to ensure the robustness, traceability, and resilience of our solutions:
Certified Secure Development Lifecycle (SDLC) by Bureau Veritas
Code review and vulnerability audits
Continuous vulnerability management through international databases and CERT alerts
Secure firmware updates
PKI (Public Key Infrastructure) for authentication and production flow management
Monitoring and patch management for products in service
At LEROY Automation, cybersecurity is at the core of our solution design. To ensure the integrity, confidentiality, and availability of industrial systems, we integrate a comprehensive set of proven software services. These technologies secure communications, authenticate access, and protect critical infrastructures from both external and internal threats.
Our equipment notably includes:
SNMP v3 protocol for secure network supervision
SSH and SFTP for encrypted connections and file transfers
HTTP/HTTPS server providing a secure configuration interface
PAM (Pluggable Authentication Modules) for advanced and flexible authentication management
OpenVPN services (client and server) enabling secure tunnel setup
GnuTLS supporting SSL, TLS, and DTLS protocols to enhance communication security
OpenLDAP services for centralized and secure identity management
NTPS client for reliable and secure network time synchronization
With this approach, LEROY Automation delivers robust solutions that comply with modern industrial cybersecurity requirements and are capable of withstanding current and future cyber threats.
LEROY Automation integrates cybersecurity across all its product ranges, serving the most demanding environments:
BRIO_NG / BGW
RIOM NG
LT200 NG
VCU SIL2 / SL2
These solutions combine industrial reliability with advanced protection mechanisms to meet the functional and cybersecurity requirements of railway and defense operators.
The LEROY Automation product range natively incorporates advanced protection mechanisms, ensuring a high level of trust for critical industrial architectures. Each device is designed to meet the increasing demands of operational security while maintaining robustness, availability, and performance.
Secure solutions within our offering include:
DataDiode
LT200
BRIO+
With these solutions, LEROY Automation provides a comprehensive range of equipment that addresses modern industrial cybersecurity challenges, offering security built in from the very design stage.
Our EMS production site is ISO 27001 certified and incorporates secure provisioning processes.
Product identities, passwords, and cryptographic keys are generated and injected in a secure environment, ensuring their authenticity and traceability from the moment they leave the factory.
Because security is an ongoing process, LEROY Automation implements:
SBOM management for each product
Continuous monitoring of vulnerability databases
Documented security updates
Coming soon: a dedicated portal for cyber alerts and a newsletter to keep our customers informed about regulatory and technical developments (CRA, NIS2…)
