Industrial Sites Face a Defensibility Gap

Most industrial sites cannot demonstrate their OT security posture under technical challenge. Regulators and insurers increasingly require verifiable operational control evidence — not policy statements or IT security frameworks retrofitted to OT. NIS2 Article 20 places personal liability on senior management. When something goes wrong, the question is not whether you had a policy — it is whether you can evidence the controls you had in place. OTVerdict produces a written defensibility position grounded in verifiable OT evidence, mapped to NIS2 Articles and ENISA Technical Implementation Guidance (EU 2024/2690). Every gap identified comes with a prioritised remediation recommendation. Annual revalidation is available for ongoing assurance. Clarity before you are asked to justify it.

The OTVerdict Defensibility Model™

A five-stage defensibility spectrum describing how clearly an organisation can evidence operational security controls under regulatory or insurer scrutiny.

Assessments evaluate evidence sufficiency against expectations reflected in frameworks such as NIS2, CAF, and industrial cyber insurance reviews.

Reactive

Controls informal or undocumented.

Basic

Controls claimed but with limited supporting evidence.

Documented

Controls defined with partial validation.

Evidence-Backed

Controls supported by structured and reviewable evidence.

Defensible

Evidence sufficient to support regulatory or insurer scrutiny.

Detailed control domains, assessment criteria, and evidence requirements are outlined in the Assessment Framework.

Built for Industrial Operators Under Regulatory Pressure

For industrial sites facing regulatory, insurer, and board-level scrutiny.

Designed for

  • OT site managers and CISOs at NIS2 essential and important entities

  • Sites under NIS2 (EU 2022/2555) or the UK Cyber Security and Resilience Bill

  • Teams needing OT-specific evidence readiness and a defensibility position

  • Industrial operators who need to demonstrate reasonable steps to a regulator

Not suitable for

  • Organisations seeking a certification badge or formal compliance certificate

  • Pure IT environments with no operational technology

  • Organisations wanting automated checklist scoring with no expert review

Pressure Drivers

  • NIS2 (EU 2022/2555) — personal liability for senior management under Article 20

  • UK Cyber Security and Resilience Bill — same technical requirements, UK-regulated entities

  • Cyber insurer evidence requirements — policies increasingly require demonstrable OT controls

  • Board-level accountability — directors need documented evidence of reasonable steps taken
