Cybersecurity for Utilities
The disruption of utilities results in widespread chaos. Outdated industrial control systems (ICS) and the interconnected nature of utility networks make this an appealing target for cybercriminals looking to cause significant disruption and extort big ransom payouts.

The utilities industry is too important to fall victim to cyberattacks
Utilities carry a security profile most generalist providers don’t fully understand.
Protecting utilities isn’t only about data protection, it’s a public safety and national resilience concern, which is exactly why utilities sit inside the UK’s Critical National Infrastructure regime.
You’re running IT and OT side by side, and they don’t age the same way. Operational technology was often built to run for decades, not to be patched monthly. Security has to work with that reality, not pretend it isn’t there.Â
Downtime isn’t just a cost, it’s a public safety event. An outage at a water treatment works or a gas network has consequences that reach well beyond the balance sheet, which is why utilities face a distinct regulatory reporting burden most sectors don’t.Â
Energy and utilities cybersecurity in numbers
What an attack could mean for your business.
Tailored energy and utilities cybersecurity solutions
We know utilities. We know your attack surface isn’t just head office IT, it’s a substation, a remote pumping station, a SCADA network that’s been running longer than most of the team maintaining it. We know that regulatory expectation and actual internal capability are two different things, and that closing that gap is the whole point.
The most common gaps we see in utilities
Some of the most disruptive utilities incidents don’t start with a sophisticated OT exploit, they start on the IT side: a phishing email, a stolen credential, a misconfigured remote access route into a network that was never meant to be internet-facing. From there, the risk is that IT compromise becomes an OT problem, because the two networks were never properly separated in the first place.Â
Operational technology sitting on the same network as corporate IT, with no clear boundary stopping an IT compromise from reaching control systems.Â
Internet-facing OT devices, PLCs and HMIs that were never meant to be reachable externally, often exposed through legacy connectivity nobody’s fully mapped.Â
Regulatory expectations from Ofwat, Ofgem, DWI, Defra and the NIS Regulations moving faster than most internal security programmes can evidence.Â
A well-documented, sector-wide shortage of people who understand both OT/ICS and cybersecurity, addressed by most operators through apprenticeships and cross-sector secondments, but rarely solved fast enough in-house alone.Â
Security Posture Assessment
Understanding your attack surface is essential when the assets at risk are critical infrastructure and operational technology. Our assessment evaluates OT and IT systems together, closing the Exposure Gap before it becomes an incident, and mapping every finding to CAF Objective A, so the output isn’t just a report, it’s the evidence your regulator actually asks for.
- Critical infrastructure and OT-specific assessment
- Actionable remediation roadmap
- Evidence for regulatory reporting
With this in place, you protect operations, defend critical infrastructure, and maintain trust with customers, stakeholders, and regulators alike, with Enhanced Readiness that holds up to audit, not just to hindsight.
vCISO Advisory Services
A great CISO closes gaps most SMBs can’t see until it’s too late, but hiring one full-time rarely stacks up against the cost, or the talent shortage that comes with it. CloudGuard’s CISO-as-a-Service gives you that strategic leadership without the headcount: experienced advisors who close the Security Confidence Gap between what you think your posture is and what it actually is.
- Strategic roadmaps
- Regulatory compliance advisory
- Risk assessment leadership
Every engagement maps to Enhanced Readiness, Optimised Responsiveness, and Maximised Resilience, so board-level guidance comes with board-level proof of progress.
Proactive protection
Utility environments require constant oversight and fast response. CloudGuard’s Managed eXtended Detection and Response (Managed XDR) service delivers round-the-clock monitoring and response across critical environments, supported by a UK-based security operations team. Routine activity is handled automatically, allowing our analysts to focus on incidents that could genuinely affect safety, uptime, or regulatory standing.
You gain faster detection, clearer incident insight and consistent protection across remote sites and central systems.
What makes us different:
- Automated alert enrichment to reduce manual effort
- UK-based SOC support available around the clock
- Faster detection using Microsoft Sentinel analytics
- Incident data that supports operational review and reporting
- Unified dashboards across IT and operational environments
AI-assisted triage and response
Fully managed MDR/XDR
Instant incident escalation and forensic support
Trusted by Customers. Backed by Certifications. Proven in the Real World.
CloudGuard is embedded in the cybersecurity industry – recognised, accredited, and trusted to protect real organisations every day.
Compliance you can prove to your regulator, not just claim
Utilities aren’t short on good intentions when it comes to compliance, they’re short on evidence. A regulator, insurer, or auditor asking “how do you know you’re secure?” needs something more concrete than an assurance. CloudGuard’s assessments are built to produce that evidence directly, mapped against NIS Regulations 2018, the incoming Cyber Security and Resilience Bill, Ofgem’s Enhanced CAF, DWI and Defra oversight, and NCSC’s underlying Cyber Assessment Framework.
Frequently Asked Questions
Why are utilities and energy providers attractive targets for cyber attacks?
Utilities rely on highly interconnected systems that support essential services. Disrupting these environments can have widespread impact, which makes them appealing targets for attackers seeking leverage, disruption, or financial gain.
What are the biggest cybersecurity risks facing utility organisations today?
Common risks include vulnerabilities in operational technology, limited visibility across remote sites, and targeted attacks on critical infrastructure. These issues can affect service availability, safety, and regulatory compliance.
How can utilities improve security without affecting uptime or safety?
Continuous monitoring, automated threat response, and clear incident processes help identify and contain threats quickly. This approach reduces risk while allowing operational systems to continue running safely and reliably.
Do utility organisations need specialist security expertise to stay protected?
Yes, utility environments are complex and often require expertise across both operational and IT systems. Many organisations address this by using external security specialists who understand critical infrastructure and industrial environments.
Do CloudGuard's utilities clients need OT-specific coverage, not just IT?
Yes, and it’s worth being upfront: CloudGuard’s core managed services are IT/Microsoft-centric. Where OT monitoring itself is required, that’s scoped as a dedicated conversation rather than assumed as standard coverage, we’ll always be clear about where that boundary sits.Â
