Digital Maintenance Gateway by RazorSecure enhances the security and efficiency of rail maintenance practices, reducing the risk and cost of cyber-attacks on the global rail network. It can be deployed on new build and legacy rolling stock. Digital Maintenance Gateway automates maintenance tasks and enables over-the-air (OTA) updates across multiple trains, reducing the need for manual access and protecting onboard systems. It provides a secure platform to control and monitor software updates and manage configuration throughout the asset's lifespan. Digital Maintenance Gateway ensures only authorized personnel have access to critical systems, mitigating the risk of unauthorized modifications or malware introduction. It eliminates dedicated service laptops, makes better use of skilled maintenance staff, and improves on-board cyber security. The solution deploys a dedicated system on-board the train that provides a managed point of access and a secure environment to run maintenance applications. It manages software maintenance tools and updates files, ensuring engineers have the necessary working software tools and update files, along with remote assistance from skilled engineers. Through direct integration with train systems, Digital Maintenance Gateway enables secure local and remote access, providing engineers with unique credentials and multi-factor authentication support. Remote access can be through a direct LTE connection or existing connectivity solutions. It meets IEC-62443 cybersecurity standards and offers a secure user interface.
