Industrial Cyber Secure Computing for Critical Infrastructure
Industrial environments face increasing threats from cyberattacks targeting control systems, data flows, and network availability. Cyber secure computing platforms help protect operational technology (OT) by integrating industrial-grade hardware with built-in security features. These solutions are designed to safeguard edge computing, data acquisition, and control operations, even in harsh environments.
Compliant with IEC 62443-4-2, making them designed to be cyber secure.
Designed for shock and vibration resistance, reliable operation in extreme temperatures, and wide voltage with support for fluctuating power inputs.
Using IEC 62443-compliant computers supports NIS2 compliance by strengthening industrial cybersecurity and aligning with its risk-based security requirements.
Cyber Secure Computing For Your Application: Where Our Solutions Work
Substation Automation and Smart Grid Networks
Substations are prime targets for cyberattacks due to their critical role in national grid stability. Secure data acquisition, control logic, and remote monitoring must all be protected from intrusion. IEC 62443-compliant computing devices help safeguard communication between IEDs (Intelligent Electronic Devices), SCADA systems, and control centers by enabling secure boot, encrypted data handling, and access control. These standards also support compliance with NERC CIP and IEC 61850 integration.
Railway Signalling and Control Systems
Modern rail systems use distributed computing for signalling, track monitoring, passenger information, and communications-based train control (CBTC). An attack on these systems can cause service disruption or safety hazards. IEC 62443 compliance is essential to ensure that embedded computers managing edge data are protected from tampering or malicious access.
Oil & Gas Pipeline Monitoring
Pipeline infrastructure relies on edge computing to monitor flow rates, pressure, and leak detection across remote sites. These systems often communicate over public or semi-secure networks, making them vulnerable to interception or manipulation. Deploying IEC 62443-compliant industrial computers enhances cybersecurity by incorporating device hardening, secure communication protocols (e.g., MQTT with TLS), and remote access control. These systems also align with industry safety standards such as ATEX and C1D2 when used in hazardous zones.
Smart City Infrastructure (Traffic, Utilities, Surveillance)
Smart cities use thousands of distributed endpoints to manage utilities, traffic signals, lighting, and public safety systems. These nodes must be protected against cyber threats, especially as they collect and transmit real-time data to central cloud platforms. IEC 62443-compliant computing solutions ensure each node has the necessary safeguards like signed firmware, firewall capabilities, and intrusion logging. Compact, fanless computers with wide temperature tolerance are perfect for street-level deployment.
The UC-8200 Series of Certified Computers
Moxa's UC‑8200 series of rugged, ultra-compact, ARM‑based industrial computers are the first host devices globally to earn IEC 62443‑4‑2 Security Level 2 certification, featuring TPM 2.0 secure boot, hardware root‑of‑trust, secure update mechanisms, disk encryption, intrusion detection, and automated failover. IEC 62443-4-2 certification ensures robust cybersecurity, helping safeguard critical operations and maintain secure, uninterrupted data communication.

Our work on cyber secure projects usually follows a defined process. We start by understanding the environment and application in detail, then agree a suitable hardware platform, build and validate systems in the UK, and finally manage changes and lifecycle.
Projects typically start with a requirements capture phase. This covers environmental conditions such as temperature range, dust levels, vibration and cleaning regime; electrical considerations such as supply, earthing and panel layout; performance requirements; I/O and expansion needs; relevant standards or approvals; and expectations around lifecycle, volume and support.
Based on this information, suitable hardware platforms are shortlisted and reviewed. CPU class, memory, storage, I/O, expansion options and mounting arrangements are agreed, along with any specific BIOS or firmware requirements. For repeat deployments, a small number of standard builds are usually defined to simplify stocking, rollout and support.
Systems are then assembled and validated in the UK. This includes physical assembly, OS installation and configuration, loading of customer images where required, and burn-in and functional tests defined for the project. The goal is that systems arrive on site ready to be integrated with minimal additional work.
Once deployed, attention shifts to lifecycle support. Agreed configurations are documented and controlled as a bill of materials. Changes announced by manufacturers are monitored, and when they occur, suitable replacement options are identified and discussed. Where appropriate, last-time-buy planning and controlled transitions are used to minimise disruption to machines and production lines.
