Is your SOC 24/7 and UK-staffed?

Yes. Our team operates 24x7x365 without outsourcing or nearshoring.

Can you integrate with our legacy OT systems?

Absolutely. We specialise in custom detection engineering for hybrid IT/OT environments.

How do you handle compliance like NIS2?

We align with NCSC and NIS2 guidance, providing tailored support for audit preparation, resilience testing, and incident reporting.

Our data needs to be stored in the UK. Can you do this?

Yes. Through our proprietary SOC and case management platform we guarantee UK data sovereignty.

What is SOC-as-a-Service for Critical Infrastructure?

It's a fully managed, threat-led cyber defence solution delivered from a UK-based SOC, tailored to protect vital CNI systems.

What certifications should a UK-based SOC have?

Analysts should hold SC or NPPV3 clearance. Providers must ensure UK sovereignty and NCSC alignment.

What's the difference between SIEM and SOC?

A SIEM collects and stores security data. A SOC actively monitors, triages, and responds to threats in real-time.

AI Native Cyber Security & SOC-as-a-Service for Critical National Infrastructure (CNI)

The CNI Threat Landscape

Critical national infrastructure operates at the intersection of physical and digital risk. Energy networks, water systems, transport, health services, and communications all depend on operational technology that was designed for reliability, not security. As IT and OT environments converge, the exposure grows.

Nation-state threat actors treat UK CNI as a priority target. Their goal is not always immediate disruption, pre-positioning within industrial control systems, long-term persistence, and intelligence gathering are common objectives that standard IT-focused monitoring cannot detect. The NCSC has been explicit: CNI operators face a qualitatively different threat than most organisations, and their security arrangements need to reflect that.

The regulatory picture has also shifted. NIS2 and IEC 62443 set clear expectations for CNI operators on risk management, detection capability, incident reporting, and supply chain security. Meeting those expectations requires a SOC that understands OT environments, not one retrofitting IT monitoring onto industrial systems.

Why Unified IT/OT SOC Matters for CNI

Most managed security providers monitor IT environments. Some have added OT monitoring as an add-on. e2e-assure built its SOC around the convergence of IT and OT from the start.

The distinction matters because threats rarely respect the boundary between your corporate network and your industrial control systems. An attacker who gains a foothold in an IT environment and moves laterally into OT — or vice versa — will not be visible to a provider watching only one side. Unified detection across both environments, with analysts who understand the behaviour of SCADA systems, PLCs, and ICS alongside standard IT infrastructure, is what CNI protection actually requires.

e2e-assure is the UK’s only provider of a 100% sovereign, fully connected IT/OT SOC capability. Every analyst holds SC or NPPV3 clearance. All data is processed and stored in the UK. Detection engineering is built specifically for CNI attack vectors, not adapted from generic templates.

For organisations requiring maximum resilience, the Enterprise tier adds Digital Twin Attack Simulation, allowing you to test your detection and response against realistic attack scenarios without touching live operational systems.

Cumulo: AI-native IT/OT protection for critical infrastructure

Every e2e-assure customer is onboarded onto Cumulo, our AI-native SOC platform. For CNI operators, the Standard OT and Enterprise tiers deliver the capabilities that industrial environments need.

OT Asset Discovery and Baselining. You cannot protect what you cannot see. Cumulo builds and maintains a live inventory of your OT assets, establishing behavioural baselines that make anomalous activity detectable.
Native OT integrations. Cumulo integrates natively with EmberOT, TXOne, and Claroty — the leading OT security platforms — bringing industrial telemetry into unified detection alongside your IT environment.
AI Analyst Engine. Every alert across both IT and OT environments is reviewed simultaneously by a council of specialist AI agents. MITRE ATT&CK mapping, risk scoring, and forensic planning run in parallel before findings reach your analyst team. Investigation time drops from hours to minutes.
Automated threat hunting. 40+ hunt rules run continuously across your environment. New indicators of compromise are queried against historical log data the moment they are identified — including across OT telemetry.
Live compliance dashboards. Real-time visibility of your posture against NIS2, IEC 62443, and CAF. Audit evidence is maintained continuously, not assembled under pressure.

Key Outcomes for CNI Clients

Unified IT/OT visibility

A single, consolidated view of threats across your entire estate — IT and OT — eliminating the blind spots that separate monitoring creates.

Faster detection across industrial environments

AI-led triage and 40+ automated hunt rules mean threats in OT environments are identified and escalated with the same speed and context as IT alerts.

Compliance confidence

Live dashboards against NIS2, IEC 62443, and CAF give your governance and operations teams continuous evidence of posture — not a point-in-time snapshot.

Integration with your existing investments

Cumulo connects with your current security tooling and OT platforms. You do not need to replace what already works.

What Sets Our UK-Based SOC Apart

Common CNI Issues

Legacy OT systems were designed for operational reliability, not security monitoring — many generate little or no telemetry that standard IT tools can process.
IT and OT environments are typically monitored separately, creating visibility gaps that adversaries exploit during lateral movement.
Many managed security providers lack analysts with genuine OT expertise, or use offshore staffing that creates sovereignty and compliance risks.

e2e-assure’s Solution

Cumulo’s OT telemetry analyser processes industrial system data that standard IT monitoring cannot handle, giving analysts visibility into SCADA, ICS, and PLC behaviour alongside IT events.
Our unified IT/OT SOC brings both environments into a single detection and response operation. Threats that cross the IT/OT boundary are visible, triaged, and acted on as one incident.
All analysts are UK-based and hold SC or NPPV3 clearance. There is no offshore staffing at any service tier. UK data sovereignty is guaranteed.
