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.
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).
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.
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.
