Connecting industrial systems, networks and data to enable secure, scalable and resilient operations

Enquire about industrial ICT

Industrial ICT underpins modern connected operations.

FAIRFIELDS designs, builds and delivers the infrastructure that enables systems, networks and data to work together securely and reliably. From instrumentation and PLC systems through to enterprise platforms, we create connected environments that support performance, resilience and long-term operational flexibility.

As industrial environments become more connected, Industrial ICT is fundamental to performance, visibility and control. It enables the integration of instrumentation, control systems and operational technology with higher-level platforms such as SCADA, historians, MES and ERP systems, ensuring data flows securely and effectively across the organisation.

FAIRFIELDS delivers Industrial ICT solutions across the full lifecycle, from assessment and architecture design through to implementation and long-term support. By combining engineering, control and digital expertise, we deliver complete, working infrastructure that meets real operational requirements, balancing security, availability and maintainability.

But what does it included?

Industrial Network Design and Delivery

We design and deliver networks ranging from simple machine-level connectivity through to large, distributed architectures across single and multi-site operations. These networks connect instrumentation, PLC systems and control platforms with SCADA, historians and enterprise systems, enabling reliable and structured data flow.

Where appropriate, architectures are aligned to the Purdue Model, with clear segmentation between operational layers. Designs follow IEC 62443 principles and defined Security Level Targets (SL-T), embedding cyber security into the network while maintaining system availability and integrity.

Industrial ICT Delivery Team

Our dedicated Industrial ICT team combines IT, networking and control systems expertise, with extensive experience in industrial automation environments.

We design and deliver secure, robust network architectures that meet defined operational requirements. By working across both IT and OT domains, we ensure systems are engineered to support how assets are controlled, monitored and maintained in practice.

Industrial Connectivity and Infrastructure

We deliver Industrial ICT solutions across a range of connectivity and communication methods, including leased lines, private cellular (4G/5G APNs), fibre optic and copper networks, and industrial wireless systems.

Solutions are selected based on operational requirements, environmental conditions and performance needs, ensuring connectivity is reliable and secure across both localised systems and geographically distributed assets.

Installation and Commissioning

We deliver Industrial ICT systems end-to-end, from installation through to configuration and commissioning within live operational environments.
This includes the deployment of network infrastructure, routing and switching equipment, server hardware and virtualised platforms. We design and install structured cabling systems, including fibre and copper networks, and carry out wireless and network surveys to inform design and validate performance.

Supporting infrastructure such as UPS and power resilience systems is also developed to ensure continued operation. All systems are tested, integrated and commissioned as complete, working solutions.

Connecting Plant to Enterprise

We integrate operational technology with enterprise systems, connecting instrumentation, PLCs and control systems to platforms such as SCADA, historians, MES and ERP.

By structuring how data is collected and shared, we enable clear visibility across operations and the wider business. This supports performance monitoring, reporting and informed decision-making, while ensuring control systems remain stable, secure and fit for purpose.

Cyber Security and Compliance

Cyber security is embedded within our Industrial ICT solutions. We design and implement architectures aligned with IEC 62443, applying segmentation, secure access and defence-in-depth principles across networks and systems.

By aligning solutions to defined Security Level Targets (SL-T), we ensure infrastructure is protected while maintaining availability, safety and operational performance. This approach ensures systems are secure by design, not retrospectively applied.

Lifecycle Support and Maintenance

Industrial ICT systems require structured, ongoing support to remain secure, reliable and effective. We provide monitoring, maintenance and patch management aligned to operational constraints, ensuring systems continue to perform without unnecessary disruption.

Our approach covers the full lifecycle, from assessment and design through to implementation and long-term support. This ensures infrastructure remains aligned to operational requirements, adapts to change and continues to meet security and performance expectations over time.
