The industrial sector is currently undergoing a profound transformation, driven by process digitalization, system interconnection, and the integration of automation, software, and cybersecurity.

In this context, the growing complexity of distributed architectures, advanced control systems, and IT/OT integration requires a rigorous engineering approach, even beyond traditionally safety-critical environments.

NIER applies methodologies and expertise developed in the railway sector to the industrial domain, working on control software, PLCs, supervision systems, and automation architectures. Activities include development, refactoring, reverse engineering, and requalification of existing systems, with particular focus on verification and long-term sustainability.

The approach integrates software engineering, system engineering, and cybersecurity, aligned with key regulatory frameworks (IEC 61508, IEC 62061, IEC 62443, EU Machinery Regulation 2023/1230). In this way, we support manufacturers and operators in managing the increasing complexity of processes while ensuring compliance, reliability, and safety of industrial systems.
