OT / ICS Cyber Security

Security engineered into your control systems from the design stage — aligned to IEC 62443 and the NCSC Cyber Assessment Framework, built by engineers who understand both OT and the threat.

// Overview

Security that fits how the plant runs

Operational technology can't be secured with IT tooling bolted on afterwards. We engineer security into control systems by design — segmenting networks, controlling access and hardening devices — so protection fits how the plant actually runs and doesn't get in the way of operations.

Our work aligns to IEC 62443 and the NCSC Cyber Assessment Framework (CAF).

// What's included

From assessment to defensible architecture

  • OT security assessmentsRisk and vulnerability assessments against IEC 62443.
  • Zones & conduitsNetwork segmentation and secure architecture design.
  • Secure remote accessSafe maintenance access without opening the plant up.
  • Device hardeningBaseline configuration and attack-surface reduction.
  • Secure-by-design buildsSecurity engineered into new systems from day one.
// Secure by design

Protection built in, not bolted on

The cheapest, strongest security is the kind that's designed in from the start. We build defensible architecture into new systems and can retrofit sensible, proportionate controls into existing ones — always balancing protection against the realities of a live process.

IEC 62443 aligned — the international standard for OT security.
NCSC CAF ready — mapped to the UK framework for CNI.
Segmentation first — zones and conduits that contain, not just detect.
Operationally aware — controls that protect without stopping the plant.
Industry Experts — we bring in named IT/OT experts when required to bring you peace of mind.
