IEC 62443 Cyber Secure Networks
Protect your industrial networks with IEC 62443-aligned, cyber-secure switches and routers built for critical infrastructure.
Industry Insight. Technology Know-how.
Secure and Rugged Networking Solutions for Industrial Environments
As industrial systems become more connected, the risk of cyberattacks targeting critical infrastructure continues to grow. Industrial networking devices must now meet not only environmental challenges, like extreme temperatures, vibration, and electrical noise, but also strict cybersecurity requirements. Rugged networking solutions that comply with the IEC 62443 standard help protect operational technology (OT) networks from unauthorised access, data breaches, and system disruptions. These cyber secure devices are essential in modern industrial environments where system availability are non-negotiable.
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.
IEC 61850-3 communication standard for electrical substation automation systems in the Power and Energy market.
Cyber Secure Networking For Your Application: Where Our Solutions Work
Transportation Systems (Rail, Marine, Aviation)
From onboard control networks to wayside and terminal systems, transportation infrastructure relies on uninterrupted communication. Cyber-secure networking devices protect signaling systems, passenger information, and remote monitoring equipment from interference and malicious attacks. IEC 62443-compliant networking hardware ensures that public and private communication channels remain separate, encrypted, and continuously monitored for anomalies.

Substation Automation and Smart Grid Networks
Electrical substations and smart grid environments are high-value targets for cyber threats due to their role in national power infrastructure. Networking switches and routers used here must offer secure remote access, encrypted communication, and intrusion detection to prevent unauthorised control or shutdowns. IEC 62443-compliant devices help ensure that data flows are protected and segmented across substations, improving both cybersecurity and grid resilience.

Water Treatment and Critical Infrastructure
Water and wastewater treatment plants depend on industrial networks for flow regulation, chemical dosing, and monitoring. A cyberattack on these systems can have serious public health consequences. Networking switches with built-in cybersecurity features like port-level control, secure firmware updates, and IEC 62443 compliance protect essential infrastructure from both internal and external threats.

Manufacturing and Industrial Automation
As factories integrate IIoT devices and cloud-based control, cyber risks increase. Networking devices in these environments must support role-based access control (RBAC), VLAN segmentation, and real-time traffic monitoring. IEC 62443-compliant switches help isolate production zones, authenticate connected devices, and prevent lateral movement from compromised nodes, ensuring the continuity and safety of automated operations.
IEC 62443-4-2 SL2 Certified Networking Devices
IEC 62443-4-2 SL2 is the globally recognised standard for cybersecurity in industrial automation and control systems (IACS). Networking devices that meet this standard are designed to support secure-by-design principles. In addition to cybersecurity, networking equipment deployed in industrial environments must also be physically resilient. Rugged networking devices are engineered to operate in wide temperature ranges, resist shock and vibration, and withstand exposure to dust, moisture, and electrical noise.

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.

Industrial Secure Routers
Moxa's industrial Ethernet solution includes integrated network security through cyber-hardened firmware and software. Additional security is added through the EDR series secure router, which combines firewall, VPN, and NAT functionality with Gigabit bandwidth to increase security protection on sensitive networks and defend mission critical assets against Internet attacks, unauthorised access, or intrusion.
