Operationalising OT Cyber Risk
A Board-to-Plant-Floor Operating Model Translating Risk Appetite into PLC Configuration
The institutional operating model boards retain when contracts, regulators, and market confidence converge on the same fault line. Decision architecture for environments where information is incomplete and consequences are irreversible.
Organisations do not lose systems first. They lose decision authority. Then everything else follows.
This doctrine exists because the distance between a near-miss and a career-ending breach is one unsigned control.
Not advisory. Not consultancy. The governance infrastructure that holds when the regulator is already in the building.

I accept 2–3 mandates per calendar year. Engagement requires executive authority or board resolution.
Who this is for

Organisations do not lose systems first. They lose decision authority. Then everything else follows.
Three stages. Procurement-grade artefacts at every step. Designed for boards under regulatory scrutiny.
A 60-minute confidential conversation. We map the decision authority gap, regulatory exposure window, and the artefacts your board, regulator, or counterparty will require.
A signed scope tied to specific outcomes — control closures, evidence chains, governance architecture, or interim CISO coverage. Procurement-grade contract on day one.
Doctrine-grade execution against the mandate. Every output is regulator-ready and board-survivable: control matrices, evidence chains, accountability maps, decision papers.
When the regulator is already in the building, the work cannot be delegated to junior consultants. It has to land with the named principal.
The principal who signs the doctrine is the principal who delivers it. No partner-to-junior handoff.
Every output is regulator-ready and board-survivable. Evidence chains, accountability maps, decision papers — not slideware.
900 published doctrine frameworks, peer-reviewed at UCL & Imperial. The IP that the work runs on is named, citable, and counterparty-validated.
Named references available under NDA. Quotes condensed and anonymised for compliance.

Quotes are presented in anonymised form to preserve client confidentiality. Full attribution and supporting references are available under NDA to authorised regulator-side counterparties.
Senior authority direct — shaped by, and operationally fluent within, the audit, advisory, consulting, technology and managed-service ecosystems that boards, regulators, and procurement teams already trust.
Why this matters. Procurement, board, and CISO offices read these names as proxies for operating tempo, multi-vendor fluency, audit-grade discipline, and regulated-sector cadence. Retain me directly and that lineage is preserved — without partner-tier markup and without delegation to junior tiers.
Company names appear solely to describe prior professional experience within and alongside teams from these organisations as part of previous employment. No endorsement, sponsorship, partnership, or current affiliation is implied. References available under NDA where appropriate.
