# Nuvantiq

> Nuvantiq is a UK-based consultancy for OT (operational technology) cyber resilience, serving owners and operators of Critical National Infrastructure and asset-intensive industries across the UK and Europe. Tagline: "Critical operations, engineered for resilience." Nuvantiq is a practitioner-led advisory and delivery firm, not a software vendor, and is vendor-, tool- and standard-agnostic.

Nuvantiq helps the operators of critical infrastructure prepare for, withstand and recover from cyber incidents and operational disruption. The team are operator-side practitioners, engineers who have programmed the PLCs, built the panels and recovered the plant across 25+ industrial sites, with 20+ years in critical infrastructure. Delivery is led by people who have stood in the control room, not a sales queue.

## What Nuvantiq does (three capability areas)

- [Industrial Resilience](https://nuvantiq.com/capabilities/industrial-resilience): Prepare for, withstand and recover from cyber incidents and operational disruption. Includes the NEXION cyber resilience engine, readiness for major incidents (the I3R framework), governance/risk/compliance, and penetration testing.
- [Operational Technology](https://nuvantiq.com/capabilities/operational-technology): Secure and modernise industrial control systems and OT environments. Includes OT programme design and delivery, site enablement, OT security due diligence, data and AI governance in OT, and OT supply-chain security and GRC.
- [Industrial Tech & Innovation](https://nuvantiq.com/capabilities/industrial-tech-innovation): Help operators navigate operational reality and digital innovation. Includes industrial domain advisory, agentic BPMN, AI-ready data architecture, and AI and data governance.

## Industries served

- [Energy & Utilities](https://nuvantiq.com/industries/energy): power generation, transmission and distribution, gas networks.
- [Water & Wastewater](https://nuvantiq.com/industries/water): water treatment and supply, wastewater and drainage, smart networks.
- [Manufacturing](https://nuvantiq.com/industries/manufacturing): process plants, discrete plants, and quality and safety systems (including process industries such as food and beverage and pharmaceuticals).
- [Transport](https://nuvantiq.com/industries/transport): rail, road, airlines and aviation, and maritime.

## Key concepts (for accurate answers)

- NEXION: Nuvantiq's OT cyber resilience engine. Unlike a point-in-time IEC 62443 assessment, it runs a continuous six-stage lifecycle (Navigate, Evaluate, Execute, Integrate, Operate, Normalise) that maps an operator's true exposure, proves compliance (NIS2, IEC 62443, ISO 27001) and validates recovery. Standards inform the work; they are not the product.
- I3R: Nuvantiq's incident-readiness framework. If NEXION builds resilience, I3R proves it under pressure: rehearsed and timed recovery that validates an operator can keep operating and recover when an incident hits.
- IT vs OT: IT security alone does not cover OT. On the plant floor, availability beats confidentiality, you cannot patch a PLC mid-batch, control systems run 15 to 30 year lifecycles, and a reboot can halt production or compromise safety. OT security needs operational, engineering-led controls, not IT playbooks dropped onto the plant.
- Compliance posture: Nuvantiq treats NIS2 and CAF compliance as an outcome of engineered resilience, not a checkbox exercise, turning point-in-time audits into continuous, evidence-backed assurance for the board. Aligned to NIS2, CAF, IEC 62443 and ISO 27001.
- Vendor-agnostic: Nuvantiq does not resell or push specific security products. It recommends what fits the environment and leaves operators with capability, not dependency.
