Unified IT/OT threat detection and response for energy producers, grid operators, and utility providers. Cumulo’s AI-native SOC platform. SC-cleared UK analysts. 24x7x365.
The UK Utilities & Energy sector is essential infrastructure. It is also one of the most targeted sectors for state-sponsored attack, ransomware, and operational disruption.
Smart grid expansion, distributed energy systems, and increasing connectivity between operational and corporate networks have significantly widened the attack surface. Legacy OT environments — many operating on protocols and hardware never designed with cyber security in mind — sit alongside modern cloud platforms, creating complex kill chains that are difficult to detect and contain with traditional monitoring tools.
Attackers target utilities because the business case is clear: disruption causes immediate public impact, pressuring operators into rapid response or payment. Ransomware groups and state-sponsored actors have both demonstrated a willingness to target UK and European energy infrastructure, with incidents resulting in prolonged operational outages and regulatory scrutiny.
Compliance obligations are tightening simultaneously — NIS2, CAF, IEC 62443, and ISO/IEC 27019 all impose requirements that most organisations are still working to meet.
Every e2e-assure customer operates on Cumulo, our AI-native SOC platform. For utilities and energy clients, the capabilities with the most immediate impact are:
OT Asset Discovery & Baselining. Utilities and energy operators frequently lack accurate visibility of what OT assets exist across their estate — particularly in legacy control environments. Cumulo’s OT Asset Discovery & Baselining capability builds and maintains a complete, up-to-date inventory of your OT environment automatically, establishing a known-good baseline for anomaly detection. Available now.
AI Analyst Engine. Every alert — across your IT systems, OT networks, and industrial control environments — is reviewed simultaneously by a council of specialist AI agents. Threat identification, risk scoring, MITRE ATT&CK for ICS mapping, and safety-impact tagging run in parallel. Engineers and security teams receive context-rich verdicts, not raw alerts to triage manually.
Threat intelligence at scale. 66 curated intelligence feeds, 1.7 million active indicators, and automated threat briefs tailored to energy sector adversary activity. Sector-specific intelligence surfaces threats relevant to utilities infrastructure early, not after indicators appear in generic feeds.
Automated threat hunting. 40+ automated threat hunt rules run continuously, including detection logic built specifically for OT attack patterns — lateral movement between IT and OT zones, abnormal command sequences, and manipulation of set-points or process values.
Live compliance dashboards. Real-time visibility of your security posture mapped to CAF, NIS2, IEC 62443, and ISO/IEC 27019. Audit evidence maintained continuously, not assembled under pressure before an assessment.
e2e-assure is not a generalist provider adapted for utilities. We have over a decade of experience protecting critical national infrastructure, including energy producers, distributors, and utility operators across the UK.
Our SOC-as-a-service is built around the realities of mixed IT/OT estates: protocol-aware detection across SCADA, Modbus, OPC-UA, and MQTT; passive integration that does not disrupt control system operations; and analysts with the clearance and experience to operate in regulated, sensitive environments.
Credentials that matter to utilities and energy clients: SC and NPPV3-cleared analysts. 100% UK sovereign operations and data residency. 24x7x365 monitoring across IT and OT. Mapped compliance support for CAF, NIS2, IEC 62443, and ISO/IEC 27019. Native OT integrations with EmberOT, TXOne, and Claroty.

Cumulo's OT Asset Discovery & Baselining gives your team an accurate, maintained inventory of every asset across segmented control networks — the foundation for effective detection.
AI-led triage and sector-specific detection engineering identifies threats earlier in the kill chain. 3x faster detection and 60% fewer false positives compared to generic monitoring approaches.
Threats are tagged by operational impact — safety-critical, service degradation, or data exposure — so engineers and security teams focus on what matters without working through an undifferentiated alert queue.
Live dashboards and continuous audit reporting across CAF, NIS2, IEC 62443, and ISO/IEC 27019 mean your compliance evidence is always current, and assessment preparation does not become a separate project.
Legacy OT networks are invisible to most monitoring tools. Assets are undiscovered, protocols unsupported, and telemetry gaps leave blind spots that attackers exploit.
Most providers are not equipped to support the regulatory frameworks utilities operators face — CAF, NIS2, IEC 62443, and ISO/IEC 27019 require specialist knowledge that generic MSSP services do not carry.
Alerts from operational environments without safety-impact context create noise that engineers cannot act on efficiently — slowing response when speed matters most.
Cumulo integrates natively with EmberOT, TXOne, and Claroty, and deploys protocol-aware telemetry collectors passively across your control environment, no downtime, no active interference. OT Asset Discovery & Baselining fills the inventory gap from day one.
Our compliance mapping covers CAF, NIS2, IEC 62443, and ISO/IEC 27019 as standard, with structured evidence and live dashboards maintained continuously.
Every alert is tagged by operational impact before escalation. Your team sees whether a threat affects safety-critical systems, service continuity, or corporate infrastructure, before they open the ticket.
A 24x7x365 managed detection and response capability built for hybrid IT/OT infrastructure. We detect, investigate, and escalate threats across your full estate — from corporate network to control room — with analysts who understand both environments.
Yes. Cumulo deploys protocol-aware telemetry collectors and passive sensors tuned to industrial protocols including SCADA, Modbus, OPC-UA, and MQTT. Existing control system architecture does not need to change.
Yes. Cumulo has native integrations with EmberOT, TXOne, and Claroty, and supports a wide range of OT monitoring platforms. We work within your existing technology estate, not around it.
Yes. Our detection engineering and SOC processes are mapped directly to these frameworks. Cumulo maintains live compliance dashboards and generates audit-ready reporting, reducing the preparation burden for assessments.
We become your SOC. Our service is designed to operate as the primary security operations function for critical infrastructure operators, with the clearances, capability, and sector knowledge to support your organisation fully.
