Industrial Networks that Connect Systems, Data and Operations
Enquire about industrial networks and cyber security
Industrial networks form the communication backbone of modern industrial environments.
They connect equipment, systems and data platforms across facilities, enabling visibility, automation and operational insight. FAIRFIELDS design and implement secure, resilient industrial networking solutions that support operational technology, enterprise connectivity and digital systems while maintaining the reliability and security required in critical industrial environments.

• Allen Bradley Remote I/O (RIO)
• RS232 / Serial communications
But what does it included?
The Connected Enterprise
Industrial organisations increasingly rely on operational data to support decision-making, performance monitoring and asset optimisation. Achieving this requires reliable integration between operational technology environments and enterprise IT systems. FAIRFIELDS help bridge the gap between these environments. Our engineers understand the operational priorities of industrial systems, such as availability and safety, while also supporting IT teams with network architecture, connectivity and governance. By supporting both disciplines, we help organisations develop practical strategies for IT and OT convergence, enabling operational data to be securely and reliably integrated into wider enterprise systems.
Network Security & Resilience
As industrial environments become more connected, protecting operational technology from cyber threats is critical. Industrial networks must be designed to maintain security while ensuring systems remain available and reliable.
FAIRFIELDS apply recognised industrial cyber security practices when designing network architectures. This includes the implementation of segmentation, firewalls, VLANs, controlled access zones and secure remote connectivity.
Our engineers are trained to expert level in the ISA/IEC 62443 industrial cyber security standard, allowing us to design and assess systems using internationally recognised frameworks for securing industrial automation and control systems.
We also support organisations in aligning their infrastructure with emerging regulatory requirements, including the NIS2 Directive, helping ensure critical systems are designed and managed with appropriate levels of resilience and cyber security governance.
Wireless & Remote Connections
Wireless networking and remote connectivity can significantly improve operational flexibility, particularly for large facilities, remote assets or mobile equipment.
FAIRFIELDS design and implement secure wireless infrastructure and remote access solutions that allow operators and engineers to monitor and maintain systems without compromising security. These systems are designed with strict access control, authentication and monitoring to ensure connectivity remains secure.
Network Obsolescence and Migration
Many industrial facilities continue to rely on legacy communication networks that remain critical to plant operation. As equipment ages and spare parts become more difficult to obtain, organisations must consider how these systems will be supported or replaced.
FAIRFIELDS help clients assess existing network infrastructure and develop strategies for maintaining or upgrading ageing systems. This may include integrating legacy networks into modern architectures or planning staged migration to newer technologies while minimising disruption to operations.
