A Practical Solution: Quantify, Reduce, and Transfer OT Cyber Risk

This is part four of a 4-part series for infrastructure fund professionals (GPs, portfolio operations, and risk leaders) focused on Operational Technology (OT) cyber risk and cyber-physical loss. See the links to Part one, Part two, and Part three.

Infrastructure investors are increasingly expected to answer three questions with evidence: What is our OT-driven cyber-physical loss exposure? What is the mitigation plan and the expected risk reduction? What portion is credibly transferable, and on what terms?

Answering these questions consistently across a portfolio is difficult when inputs are qualitative, asset-specific, and scattered across operators, advisors, and insurers. A repeatable OT Cyber Risk Quantification workflow is the most practical way to move from awareness to decisioning.

I am Jose Seara, CEO and founder of DeNexus. I built DeNexus after working in infrastructure and seeing first-hand how often cyber diligence fails to capture the OT pathways that drive cash flow interruption, refinancing friction, and valuation impairment.

A fund-ready operating model for OT cyber risk

A pragmatic model aligns to the investor lifecycle: diligence, acquisition, value creation, refinancing, and exit. The goal is not to create additional bureaucracy. The goal is to generate investor-grade outputs in a repeatable way and to track risk reduction over time.

Diligence: quantify OT scenarios and identify concentration risks before investment decisions.
Post-close: prioritize mitigations with clear risk-reduction rationale and feasible implementation sequencing.
Refinancing and exit: provide evidence-based risk posture and residual exposure narratives.
Insurance renewal: support underwriting with scenario quantification and control effectiveness.
Asset-level and portfolio-level views (including concentration and systemic exposure).
Scenario-based loss estimates tied to OT pathways and operational consequences.
Prioritized mitigations linked to measurable risk reduction and feasibility constraints.
Investor-ready reporting for IC, boards, and portfolio governance.
Insurance-ready documentation to improve clarity in placement and renewal discussions.
Model OT loss scenarios per asset (outage, safety constraints, physical impacts, recovery timelines).
Quantify exposure (expected loss and tail loss) with transparent assumptions and evidence trails.
Prioritize mitigations by risk reduction, implementation feasibility, and operational constraints.
Support risk transfer decisions with insurance-ready outputs and clear retained-risk statements.

What DeNexus´ DeRISK delivers for infrastructure investors

DeRISK is an OT Cyber Risk Quantification platform designed to translate OT realities into investor decision inputs. It provides scenario-based loss estimates, mitigation prioritization tied to quantified risk reduction, and reporting suitable for investment committee (IC) packs and portfolio oversight.

How the workflow typically runs

At a high level, the workflow is simple: model scenarios, quantify financial exposure, act on mitigations, and track residual risk. DeRISK is intended to make this repeatable across assets and consistent across stakeholders.

Why this is the most direct path to value protection

When OT cyber risk is quantified, investors can allocate attention and capital where it matters most. This reduces the chance that an infrequent but severe cyber-physical event becomes a liquidity issue, a refinancing surprise, or a valuation impairment.

It also improves alignment: operators understand which actions reduce risk; risk teams can monitor progress; and insurers and lenders receive a defensible narrative.
