Critical National Infrastructure (CNI) refers to the essential systems and assets that are vital to the UK’s security, economy, and public health. These include sectors such as:
As digital transformation accelerates across these sectors, the attack surface grows. State-sponsored actors, cybercriminals, and insider threats frequently target CNI due to its societal importance and operational complexity.
With increasing regulatory pressure from frameworks like NIS2, CNI organisations must ensure their security solutions are UK-sovereign, compliant, and tailored to operational realities. Data residency, SC/NPPV3-clearance, and operational technology (OT) expertise are not just value-adds—they’re requirements.

Seamless integration with current systems, maximising existing investments.
Improved risk posture with sector-specific tuning based on active Threat Intelligence.
Gain full visibility across all industrial assets, to strengthen cyber resilience.
Outdated legacy security systems can’t keep up with modern APTs.
Overseas SOCs raise compliance and data sovereignty issues.
Generic detection fails to capture sector-specific threats.
Current OT incumbent cannot integrate into our IT monitoring.
Our second generation OT Telemetry Analyser allow for increased visibility of modern APTs across OT industrial systems.
We guarantees UK data residency and staffing, reducing risk and increasing trust.
Our IT/OT detection engineering and threat intel are tailored to CNI attack vectors.
We can bring both IT and OT monitoring and alerts into the same view through CUMOULO.
Yes. Our team operates 24x7x365 without outsourcing or nearshoring.
Absolutely. We specialise in custom detection engineering for hybrid IT/OT environments.
We align with NCSC and NIS2 guidance, providing tailored support for audit preparation, resilience testing, and incident reporting.
Yes. Through our proprietary SOC and case management platform we guarantee UK data sovereignty
It’s a fully managed, threat-led cyber defence solution delivered from a UK-based SOC, tailored to protect vital CNI systems.
Analysts should hold SC or NPPV3 clearance. Providers must ensure UK sovereignty and NCSC alignment.
A SIEM collects and stores security data. A SOC actively monitors, triages, and responds to threats in real-time.
Let’s discuss how we can tailor our threat-led, UK-sovereign SOC services to meet your organisation’s unique challenges.
