NS: controlling mission-critical rail operations through a secure integration platform

NS operates software in and around moving assets, making uptime, data integrity and safety non-negotiable. As the OT ecosystem expanded, traditional point-to-point integrations became unmanageable:

• Integrations became fragmented across suppliers and systems
• Onboarding new suppliers introduced unpredictable risk
• Visibility and control over the operational landscape decreased

More connections meant more exposure. The core question became: how do you enable growth in connectivity, without compromising safety, compliance, or control?

The Wayside Platform replaces fragmented integrations with a single, governed platform; acting as the only controlled interface between operational assets and IT systems. It is fully automated, workload-agnostic, and embeds directly into NS's environment, giving NS full authority over who connects and how.

The platform is built around four key design principles:

• Network decoupling — no direct dependencies between OT and IT
• Standardised onboarding — every asset and supplier follows the same rules
• Full control by NS — ability to monitor, intervene, or disconnect at any time
• Automation by design — reducing manual handling and operational risk

This shifts integration from custom engineering to controlled, repeatable capability. Without accumulating integration debt.

With the Wayside Platform in place, NS has fundamentally changed how it manages its digital ecosystem. The results are structural, not reactive:

• Onboarding of suppliers is faster and predictable
• Architecture is simplified and standardized across the board
• Security risks are reduced by design, not patched after the fact

Most importantly, NS retains full ownership and control over its mission-critical landscape. The platform enables growth without increasing fragility; providing the foundation to innovate, while safeguarding continuity and long-term architectural freedom.
