Infrastructure Is Evolving.
IT and OT Are Rapidly Converging.
AI Is Here to Stay.
Asset Visibility Is a Mounting Concern.
Supply Chains Are Truly Global.
How Can Utilities Demonstrate NIS and CAF Compliance?
With the Cyber Security and Resilience (Network and Information Systems) Bill progressing through Parliament, NIS and CAF compliance is a critical priority for the Utilities sector. To this end, the Exponential-e Group operates according to a comprehensive range of applicable frameworks and regulations and provides hands-on support to customers who are required to do the same, encompassing every aspect of the audit process, including asset inventories, supply chains, monitoring, incident response, resilience and continuous improvement.

Preparing the UK’s Critical National Infrastructure for the Cyber Security & Resilience Bill
Across the UK's Critical National Infrastructure (CNI), cyber security is now firmly established as a board-level priority, rather than the sole purview of IT and security teams. In response to the increasing range of cyber threats mounted by global ...

Answers to the practical technology, security, resilience and compliance questions facing Utilities organisations.
This will vary widely, depending on the legacy systems currently in place. For this reason, any network modernisation project the Exponential-e Group undertakes will begin with a period of intensive consultation and a thorough audit of existing IT/OT systems, processes, and compliance obligations. Based on this, we will deliver an in-depth project roadmap, encompassing SCADA, telemetry, serial-to-IP, phased migration, testing, rollback, parallel environments and live-site deployment. Explore our Connectivity services.
The increasingly interconnected nature of IT and OT systems across Utilities environments means that traditional cyber security ecosystems cannot simply be retrofitted to legacy systems. For this reason, the Exponential-e Group takes a ‘secure by design’ approach to network deployments, with all operational and safety risks identified at the outset of each deployment. We draw on our 20+ years of networking innovation, full solution portfolio, and self-owned network to put this into practice, utilising everything from best-in-class SASE solutions to full segmentation of critical assets, with our UK-based CSOC available to provide proactive, real-time monitoring. Explore SASE and Managed CSOC.
An end-to-end approach to security is required, encompassing all potential access points and the increasingly interconnected nature of IT and OT. Key elements include (but are not limited to) PAM/IAM, Zero Trust, temporary access, session monitoring, supplier segmentation, audit trails, remote maintenance and revocation. This requires the support of a trusted technology partner who can not only demonstrate deep knowledge of the current security and regulatory landscape, but also provide security-cleared personnel to provide on-site support, and real-time monitoring and analytics of the entire security estate. Explore Identity and Access Management.
Establishing the right underlying network is key to maximising resilience across Utilities environments. It is for this reason that the Exponential-e Group’s own enterprise-class network remains the foundation of our entire solution portfolio. We continue to develop these connections in response to evolving requirements around security, availability, and resilience, utilising true route diversity, dual access, diverse POPs, failover, 4G/5G backups, and proactive monitoring. We also offer leading-edge SASE and SD-WAN solutions, to optimise control and visibility, even for the most remote, highly dispersed sites. Explore SD-WAN.
Asset management is a key element of the NCSC’s CAF framework, requiring organisations to maintain real-time visibility of the status, dependencies, and functions of all physical and digital infrastructure. An end-to-end approach is required here, combining strategic, AI-powered automation with hands-on support and monitoring from dedicated specialists, with all asset data collated in auditable reports. This is a key element of the Exponential-e Group’s ongoing work with Utilities organisations across the UK, ensuring full control and visibility can be maintained across the next generation of integrated IT/OT infrastructure.
AI is rapidly revealing its true potential within Utilities environments, supporting predictive maintenance, asset failure prediction, anomaly detection, and demand forecasting, along with innovations around digital twinning and network optimisation. However, to achieve all these potential benefits, truly UK-sovereign infrastructure must underlay any AI initiative, ensuring all data generated by IT/OT assets remains within the UK and is only ever accessible to authorised individuals. The Exponential-e Group is already working with numerous organisations across the sector to put this into practice, as set out in our recent report. Explore Sovereign AI Platforms.
With mission-critical services now regularly targeted by global bad actors, a ‘defence in depth’ approach to security for Utilities is essential. Modern security ecosystems must be designed around the numerous interconnections between physical and digital assets, which will frequently require legacy systems to be phased out, to eliminate any hidden vulnerabilities. For this reason, establishing a robust security ecosystem should begin with a full audit of all systems and processes, conducted by a reputable third party who can demonstrate deep knowledge of the sector’s operations and compliance obligations.
