OT security consulting

Secure operational technology with the operation in mind.

We help organisations protect industrial and operational technology without losing sight of safety, availability, recovery and the realities of live environments.

Frameworks are useful when they drive better decisions.

Silicon Circle uses NIS, the NCSC Cyber Assessment Framework and IEC 62443 as practical reference points. The objective is not a compliance exercise. It is a secure, supportable environment with clear ownership and proportionate controls.

OT security work that fits the environment.

We tailor the work to your risk profile, operational model and regulatory context, then turn it into outcomes your engineers and leaders can use.

Consultant inspecting secure industrial network infrastructure

Start with the systems and assets that matter most.

We establish a defensible view of assets, dependencies and connectivity, then focus controls where they reduce the most meaningful risk.

Our network and asset hardening work covers secure configuration baselines, patching and firmware governance, privileged access, remote support, service reduction and evidence for controlled exceptions.

IT and OT belong in the same conversation.

Industrial systems increasingly depend on enterprise identity, remote access, cloud services and third-party support. We help teams manage that convergence without imposing IT controls where they do not fit.
