OT assessmentsBoard to floor

See your resilience before an incident does.

Eleven assessments of the systems that run your operation — from a one-week estate snapshot to full regulatory readiness. Evidenced against recognised standards, ranked by what it would cost the operation, written in plain English.

01 · Where most customers start

Four assessments answer most first questions.

025–7 weeks

OT Cybersecurity Assessment

A single, evidenced picture of how secure your production environment actually is — written so the plant manager and the board can act on the same document.

034–6 weeks

IEC 62443 Gap Assessment

A defensible, standard-based measurement of where you sit against IEC 62443 — and the shortest credible route to the security level you actually need.

044–6 weeks

Operational Resilience Assessment

We stress-test the operation, not just the network, against the scenarios that actually stop production — and tell you how long you would really be down.

02 · The full set

Eleven assessments. One question each.

01Industrial Cyber EssentialsWhere do we stand? One week, one site visit, marked against IEC 62443.1 week

02OT Cybersecurity AssessmentHow secure is the plant, evidenced for both the floor and the board?5–7 weeks

03Operational Resilience AssessmentCan the operation take a hit and keep running — and for how long?4–6 weeks

04IEC 62443 Gap AssessmentWhere do we sit against the OT security standard, and what closes the gap?4–6 weeks

05Backup & Recovery ReadinessCould we actually rebuild a controller, an HMI and a historian in time? We test it.3–4 weeks

06Remote Access Security ReviewEvery path into the plant — including the ones nobody documented.2–3 weeks

07OT Site Assurance ReviewA fast, low-cost health-check of one site’s controls.2 weeks

08NIS2 Readiness AssessmentDuty-by-duty readiness for NIS2, including management liability and 24-hour reporting.4–5 weeks

09Asset Discovery & Risk AssessmentWhat is really on the network — built passively, ranked by operational risk.4–8 weeks

10M&A OT Site ValidationWhat will this estate really cost to secure and integrate — inside the deal timetable.2–3 weeks

11AI Exposure ReadinessWhere AI touches operations, what data leaves, and what it is allowed to do.3–4 weeks

Every assessment ends with a costed next step — and everything we recommend, we can also deliver.

Operators, not advisors

Assessed by engineers who have written the PLC code and recovered the plant — the instincts of operators, not the theory of advisors.

Ranked by consequence

Findings are ranked by lost production, not lost data — what it would cost the operation, never a bare CVSS score.

Safe by design

Passive, escorted, read-only. Nothing we do can trip a process, so operations can say yes without a risk assessment.
