A specialised methodology to secure Operational Technology and industrial IoT without disrupting critical production. Safety and availability come first — every control is adapted to plant constraints, maintenance windows and legacy assets.
In enterprise IT the priority order is confidentiality, integrity, availability. In OT it inverts — an unsafe process state or an unplanned shutdown is the real loss event.
Non-intrusive, passive discovery that builds the inventory you cannot secure without.
A safe testing approach designed around plant reality.
Purdue-aligned zones and conduits that contain an incident instead of letting it spread.
Detection tuned for control networks, integrated with your SOC.
We prioritise the paths that can bridge enterprise systems and production networks — because those are the ones that end in downtime.
Unmanaged or shared remote paths into control networks.
Third-party engineering devices connected directly to plant assets.
IT-side compromise that pivots across a weak IT/OT boundary.
High-privilege hosts able to change control logic.
No segmentation, so one foothold reaches everything.
Typical outcomes when these are left open: unauthorised change, HMI lockout, historian loss, safety review delay, or full plant shutdown.
No response action is taken that could create an unsafe process state.
Actions are agreed with operations and engineering before execution.
Documented fallback so production can continue during containment.
Evidence captured for root cause and regulatory reporting.
Controlled restart with verification at each zone.
No. Discovery is passive and non-intrusive — we observe traffic rather than scan control devices. Any active testing is scoped with your team and scheduled inside agreed maintenance windows, with compensating controls proposed for systems that cannot be patched.
Yes. Our segmentation and architecture work is aligned to the Purdue reference model with zones and conduits, and assessments map to IEC 62443 practices alongside CII regulatory expectations.
Yes. Where patching is not possible we design compensating controls — network segmentation, protocol allow-listing, strict remote access control and targeted monitoring — so the asset is protected without touching the control logic.
Through governed access paths: jump servers, privileged access management, multi-factor authentication, session recording and time-bound approvals, so vendor connections are controlled and auditable.
