Cybersecurity & OT/IT Security

Securing the connected infrastructure we build — from the sensor to the cloud.

DISCUSS YOUR SECURITY REQUIREMENTS

IT security protects data. OT security protects physical operations.

Operational Technology (OT) encompasses the hardware and software that controls physical systems — BMS controllers, SCADA platforms, PLCs, medical devices, HVAC systems and industrial control networks. These systems were designed for reliability, not security. As they become network-connected — and as AI systems are layered on top — they become potential attack surfaces. A compromise of OT infrastructure results in physical consequences: production shutdown, building system failure, or in healthcare, direct patient risk.

Six service areas — delivered across the full infrastructure lifecycle.

OT Network Security

Network segmentation, Purdue Model implementation, firewall rule-set design and industrial DMZ configuration for BMS, SCADA and ICS environments.

Vulnerability Assessment

Structured assessment of all connected OT and IoT assets — identifying exposed attack surfaces, firmware vulnerabilities and misconfigured access controls.

Zero Trust Architecture

Identity-based access controls ensuring that only verified users and authorised devices can reach operational systems — regardless of network location.

Incident Response Planning

Documented response procedures, tabletop exercise facilitation and recovery planning — aligned to NCSC and ENISA guidance.

Compliance & Certification Support

Technical and documentary support for NIS2 (EU), ISO 27001, IEC 62443, DSPT (NHS England), Cyber Essentials Plus (UK) and ENS (Spain).

Secure-by-Design Integration

Security architecture embedded into Digital Twin and AI system design — not retrofitted after deployment.

Sector-specific regulatory requirements — across all NOVTRIQ operating jurisdictions.

NIS2 Directive

European Union

Mandatory cybersecurity obligations for operators of essential and important entities — including healthcare, energy and digital infrastructure.

ISO 27001

International

Information security management system standard — required by most enterprise and public sector procurement frameworks.

IEC 62443

International

The primary industrial cybersecurity standard — defines security levels for industrial control systems and OT networks.

DSPT

United Kingdom

NHS Data Security and Protection Toolkit — mandatory annual assessment for all NHS-connected organisations and their suppliers.

ENS

Spain

Esquema Nacional de Seguridad — mandatory security framework for Spanish public sector entities and their technology suppliers.

Security architecture tailored to operational complexity.

Healthcare

Clinical estates present a uniquely complex security environment — medical devices on the same network as corporate IT, legacy systems that cannot be patched, and patient data that carries maximum regulatory risk. NOVTRIQ addresses OT security, DSPT compliance and medical device network segmentation as integrated components of every healthcare digital twin deployment.

Industrial & Manufacturing

Production environments operate on control systems that prioritise uptime over security — PLC firmware rarely updated, remote access poorly controlled, historian databases directly accessible. NOVTRIQ applies IEC 62443-aligned security architecture to industrial environments without disrupting production operations.

Data Centres

Physical and logical security convergence is a fundamental requirement for any data centre operating at Tier II or above. NOVTRIQ integrates physical access control, OT network security and AI system security into a unified posture aligned with SOC 2 and ISO 27001 requirements.

Common questions about OT security and compliance.

What is the difference between OT and IT security?

IT security focuses on protecting data and computer systems. OT security protects operational technology systems that control physical infrastructure — like building management systems, industrial controls, and medical devices. A breach of OT systems can result in physical consequences: production shutdowns, building system failures, or direct patient risk.

Why is IEC 62443 important for industrial environments?

IEC 62443 is the international standard for industrial cybersecurity. It defines security levels, implementation practices, and assessment criteria specifically for industrial control systems. Many enterprise customers and regulatory bodies now require IEC 62443 compliance in procurement.

Is NIS2 mandatory for my organisation?

NIS2 is mandatory across the EU for operators of essential services (energy, healthcare, digital infrastructure) and important entities. If your organisation operates in the EU and provides essential services, NIS2 compliance is now a legal requirement. We can assess your exposure and recommend compliance pathways.

What does a DSPT assessment involve for NHS suppliers?

The NHS Data Security and Protection Toolkit is an annual self-assessment covering 10 security standards including access controls, encryption, incident response, and staff training. All NHS organisations and their connected suppliers must complete it.

How does NOVTRIQ approach zero trust architecture?

Zero trust means "never trust, always verify" — every user and device is authenticated and authorised before accessing OT systems, regardless of network location. We implement this through network segmentation, identity-based access controls, and continuous monitoring.

Can NOVTRIQ help with incident response planning?

Yes. We develop documented incident response procedures tailored to your operational environment, conduct tabletop exercises to test your team's readiness, and support recovery planning aligned with NCSC and ENISA recommendations.

Security must be designed in — not bolted on.

NOVTRIQ assesses your OT/IT security posture as part of every infrastructure engagement. Speak with our team to understand your current exposure and the steps required for compliance.
