Energy and Utilities Cybersecurity Statistics 2026: OT & Grid Risk

Executive overview

Executive Summary / TL;DR

Energy and utilities cybersecurity statistics in 2026 show a sector defined less by single headline incidents and more by persistent exposure across utilities IT, OT, cloud, remote access, customer-facing services, and supplier-connected environments. The strongest datasets point to five recurring realities: utilities remain breach-prone, ransomware pressure on industrial organizations remains high, DDoS volume is rising sharply, internet-facing OT exposure still persists, and third-party access remains one of the least mature control areas.

• Verizon’s 2026 DBIR utility snapshot recorded 638 utilities incidents and 597 with confirmed data disclosure, with system intrusion, basic web application attacks, and social engineering representing 94% of utility breaches.
• FBI IC3’s 2025 critical-infrastructure breakdown logged 54 ransomware complaints and 31 data-breach complaints in the energy sector, plus 25 ransomware complaints and 11 data-breach complaints in water and wastewater systems.
• OT and CPS risk remains materially tied to exposure and convergence. Claroty found 12% of analyzed OT devices contained KEVs, 7% had KEVs linked to ransomware, and 40% of organizations had those assets insecurely connected to the internet.
• Ransomware is not just an IT cost issue. Dragos tracked sustained industrial ransomware activity across electric, oil and natural gas, renewables, and water through 2025, with 49 oil and natural gas incidents and 31 electric incidents in Q4 2025 alone in its industrial victim tracking.
• Availability risk is rising alongside DDoS scale. Cloudflare said 2025 DDoS attacks more than doubled to 47.1 million, while Nozomi reported that DoS techniques made up over a third of techniques detected in customer OT/IoT environments.
• Cloud and API exposure now matter directly to utilities because customer portals, billing systems, outage reporting, distributed energy workflows, and partner integrations increasingly run through cloud and API layers. Akamai documented 150 billion API attacks during 2023–2024, and IBM reported 40% of breaches involved data distributed across multiple environments.
• The statistics are useful for budget planning only when scope is handled carefully. Utility-specific breach data, OT-wide exposure telemetry, industrial ransomware leak-site counts, internet-wide DDoS telemetry, and regulatory guidance are not interchangeable datasets.

How to Read These Statistics

Use this table before turning any statistic into a board slide, budget request, or comparison point. The source scope determines how safely the number can be applied to energy and utility decisions.

Key Energy and Utilities Cybersecurity Statistics Table

The concentration is clear. Utility breach data points to system intrusion, web attack paths, and social engineering. OT data points to exposed assets and exploitable weaknesses. Industrial ransomware tracking shows sustained pressure on electric and oil-and-gas organizations. Internet telemetry shows DDoS and API abuse continue to rise at a pace that matters to any utility running customer-facing digital services.

Quick answer: What do energy and utilities cybersecurity statistics show?

Energy and utilities cyber risk is shaped by the combination of critical-infrastructure dependence, IT/OT convergence, and availability-sensitive operations. The strongest statistics show that utilities still face real breach volume, ransomware remains persistent across industrial organizations, DDoS volume is climbing, internet-facing OT exposure has not disappeared, and third-party remote access remains a major weak point. Cloud services, APIs, smart-grid workflows, IoT, and customer portals widen the attack surface further. Regulatory pressure is increasing, but the data does not support a compliance-only response. For energy and utility leaders, the implication is straightforward: budgets should move toward visibility, exposure reduction, segmentation, recovery readiness, and repeated security validation.

Why Energy and Utilities Cybersecurity Statistics Matter

Energy and utility organizations operate attack surfaces that look materially different from standard enterprise environments. The sector spans electric generation, transmission, and distribution; oil and gas production, transportation, and refining; and water and wastewater treatment and distribution. In the United States alone, CISA describes the electricity segment as containing more than 6,413 power plants, while GAO notes that the country also relies on nearly 170,000 water and wastewater systems.

That operating model creates layered cyber risk. Utilities often combine customer and billing systems, public web services, outage and dispatch processes, remote maintenance workflows, and OT environments built around PLCs, HMIs, SCADA, historians, engineering workstations, and field communications. NIST SP 800-82 emphasizes that OT security has to account for performance, reliability, and safety requirements that differ from conventional IT security design.

The result is that impact cannot be read only through breach counts. In these sectors, a successful intrusion can affect service availability, dispatch decision-making, plant support systems, regulatory reporting, environmental controls, customer confidence, or physical process continuity. That is why the most useful energy sector cybersecurity statistics are those that help leaders judge exposure, recovery capability, and attack-path realism rather than simply count malware families or generic cyber incidents.

Methodology: How We Selected and Verified the Statistics

This article prioritized official and primary-source material first, then sector bodies, then OT/ICS telemetry and credible cross-industry cyber reports. Government and regulatory sources were used for infrastructure scope, critical-infrastructure complaint data, water-sector findings, and regulatory context. OT/ICS vendor reporting was used for exposure, ransomware, and industrial telemetry where the dataset and scope were explicit. Cross-industry reports were included only when they added decision value for cloud, API, breach cost, ransomware, or supply-chain benchmarking.

Several statistics were intentionally excluded. Where no defensible energy-specific number was available, this guide either used a clearly labeled cross-industry benchmark or stated the limitation directly. That is particularly important for insider risk, cloud compromise, and modern API abuse, where many published numbers are real but not sector-specific enough to be presented as utility statistics.

Threat landscape and statistics

Energy and Utilities Cyber Threat Landscape in 2026

The 2026 landscape is defined by the compression of once-separate attack surfaces. Verizon’s 2026 DBIR found that software vulnerabilities became the leading initial breach vector at 31% of breaches, third-party involvement reached 48% of breaches after a 60% year-over-year increase, and ransomware rose to 48% of all breaches. That combination matters to utilities because it maps directly to vendor-supported systems, internet-facing portals, remote access platforms, and multi-operator environments.

For OT and ICS defenders, the warning signs are equally clear. Claroty found KEVs on 12% of nearly one million OT devices analyzed, while 40% of organizations in the dataset had those assets insecurely connected to the internet. CISA and the FBI also warned in 2026 that adversary activity against internet-facing PLCs caused disruptions across several U.S. critical-infrastructure sectors, while CISA’s February 2026 alert on the Poland energy incident highlighted vulnerable edge devices and OT/ICS security gaps.

This is why the modern utility cyber-threat model is not just ransomware or phishing. It is a stack: exposed services, weak remote access, supplier pathways, identity abuse, customer-facing applications, OT visibility gaps, and incident-response designs that still assume IT and OT can be managed separately. The statistics support a view of energy cyber risk as a continuity and safety problem, not only a confidentiality problem.

Energy and Utilities Cybersecurity Statistics by Threat Type

The most important pattern across these threat areas is overlap. The same organization can face exposed internet services, supplier-connected remote access, cloud configuration drift, utility web-app risk, and OT segmentation weaknesses at the same time. That is why isolated control purchases often fail to change the risk picture.

Electric Power Grid and Utility Cybersecurity Statistics

Utilities-specific breach data is stronger than many buyers assume. Verizon’s 2026 DBIR utilities snapshot shows 638 incidents and 597 confirmed disclosures, with 94% of utility breaches concentrated in system intrusion, basic web application attacks, and social engineering. External actors accounted for 97% of utility breaches, and espionage appeared in 71% of utility breach motives, which is unusually high compared with many commercial sectors.

That matters because the electric power environment combines public-facing services, market and dispatch platforms, substations, remote support workflows, and increasingly distributed digital infrastructure. CISA describes the U.S. electricity segment as containing more than 6,413 power plants, and NERC continues to frame CIP standards as the backbone of mandatory security controls for the North American bulk power system.

Ransomware tracking also supports treating the power sector as a continuing target rather than a Colonial-Pipeline-only lesson. Dragos counted 31 electric-sector industrial ransomware incidents in Q4 2025 after 15 electric incidents in Q1 2025, while CISA’s alert on the December 2025 Poland energy-sector incident pointed directly to edge-device and OT/ICS weaknesses. Grid operators and utilities therefore need to think about cyber resilience as a blend of breach prevention, outage resilience, and grid-continuity preparation.

Oil, Gas, Pipeline, and Refinery Cybersecurity Statistics

Oil and gas should not be treated as an abstract critical-infrastructure category. It is an operationally distributed environment with compressor stations, pipeline control systems, terminals, refineries, contractor access, and remote assets that often rely on external communications and supplier support. CISA’s energy-sector framing explicitly includes electricity, oil, and natural gas segments, while TSA continues to maintain mandatory pipeline cybersecurity directives.

Dragos’s industrial ransomware tracking shows why that matters in practice. In Q4 2025, Dragos recorded 49 oil-and-natural-gas incidents, alongside 31 electric incidents, and it described energy-related sectors as consistently targeted throughout the quarter. Earlier 2025 tracking also showed oil and natural gas incidents in Q1 and Q2, confirming sustained attention rather than a single-quarter spike.

The Colonial Pipeline case remains relevant because it showed how an IT-side ransomware event can force operational shutdown decisions in pipeline environments. DOE states that Colonial proactively shut down its pipeline system in response to the May 2021 ransomware attack. The lesson for refinery, terminal, and midstream leaders is not that every ransomware event will hit OT directly. It is that OT-adjacent business systems can still become operational choke points.

Water and Wastewater Utility Cybersecurity Statistics

Water statistics deserve their own treatment because the sector has different economics, staffing realities, and regulatory dynamics than the power and oil-and-gas segments. GAO notes that the United States has nearly 170,000 water and wastewater systems, many of them small and resource-constrained. EPA’s 2024 enforcement alert then added a sharper warning: over 70% of inspected drinking-water systems since September 2023 were out of compliance with basic statutory requirements, and inspectors found issues such as default passwords, shared logins, and former-employee access that had not been curtailed.

Recent oversight data shows that federal attention on water cybersecurity is not theoretical. EPA’s FY 2027 congressional justification states that in FY 2025 the agency either led or accompanied inspections at over 210 community water systems, with more than 170 including an evaluation of cybersecurity risks, and conducted off-site compliance monitoring at about 340 systems.

Complaint and ransomware telemetry reinforces the point. FBI IC3 logged 25 ransomware complaints and 11 data-breach complaints for water and wastewater systems in 2025, while Dragos recorded three water incidents in Q4 2025 after lower counts earlier in the year. The right conclusion is not that water is safe because its volume is lower than manufacturing. It is that a sector with smaller teams and older estates is still facing persistent essential-service cyber pressure.

OT, ICS, SCADA, Smart Grid, and Industrial Control Security Statistics

Utilities do not need a generic explanation of OT. They need a reminder that OT security is governed by constraints that standard IT programs often underweight: safety, uptime, fragile assets, engineering ownership, specialized protocols, and consequences that extend beyond data loss. NIST SP 800-82 states directly that OT security must address unique performance, reliability, and safety requirements.

The numbers on exposure are difficult to ignore. Claroty’s 2025 OT exposures research found KEVs on 12% of analyzed OT devices, ransomware-linked KEVs on 7% of devices, insecure internet connectivity in 40% of organizations, and OT assets communicating with malicious domains in more than 12% of industrial organizations. Fortinet’s 2025 survey added that 60% of organizations experiencing an intrusion reported impact across both IT and OT systems.

MITRE ATT&CK for ICS also helps explain why utility cyber risk cannot be reduced to “patch faster.” The current ICS matrix spans 12 tactics, including Inhibit Response Function, Impair Process Control, and Impact, which are directly tied to operational disruption rather than only data theft. Smart-grid and distributed-energy environments make this more pressing because more digital connectivity means more pathways into operational workflows, as seen in CISA’s Poland alert and DOE’s DER cybersecurity guidance.

Operational risk patterns

Energy Ransomware and Extortion Statistics

Ransomware remains the most visible cyber risk in energy and utilities because it sits at the point where IT disruption, operational dependency, supplier access, and executive pressure meet. FBI IC3 received more than 3,600 ransomware complaints in 2025 with reported losses exceeding $32 million, while noting that ransomware remains among the highest reported cyber threats targeting critical infrastructure organizations. Those reported losses understate true impact because business interruption and remediation costs are often not fully captured in IC3 reporting.

Cross-industry data points the same way. Verizon’s 2026 DBIR says ransomware grew to 48% of all breaches, and the 2026 report also highlights the continued growth of third-party breaches. For energy and utility leaders, that pairing matters more than the ransomware headline alone because it shows how supplier-connected or service-provider-connected environments can become the delivery path for extortion events.

Industrial telemetry keeps the energy picture honest. Dragos documented 742 ransomware incidents affecting industrial entities in Q3 2025 and substantially higher Q4 activity, including 49 oil-and-natural-gas incidents, 31 electric incidents, 9 renewables incidents, and 3 water incidents. Those counts come from industrial victim tracking and should not be read as confirmed OT encryption cases in every instance. But they do show sustained targeting of operationally sensitive sectors.

For buyers, the implication is operational. Recovery readiness has to cover identity systems, jump hosts, VPNs, virtualization, backup orchestration, historians, dispatch-adjacent applications, billing, and customer communications. Segmentation validation and restoration testing matter because ransomware in these environments is often dangerous precisely when it remains “only” in IT.

DDoS, Cloud, API, IoT, and Internet-Facing Exposure Statistics

Availability has become a first-order cyber metric for utilities. Cloudflare reported that DDoS attacks more than doubled in 2025 to 47.1 million, with an average of 5,376 DDoS attacks every hour. In Q2 2025 alone, Cloudflare blocked more than 6,500 hyper-volumetric DDoS attacks, averaging 71 per day, and reported a peak attack size of 7.3 Tbps. That is internet-wide data, but it directly matters to utility customer portals, payment systems, DNS, outage reporting, and public communications channels.

Nozomi’s OT/IoT telemetry shows why DDoS cannot be dismissed as a “web-only” issue. In its July 2025 Trends & Insights release, Nozomi ranked Energy, Utilities & Waste among its top five targeted sectors and said network denial of service and denial of service together accounted for over a third of techniques associated with raised alerts in customer environments.

Cloud and API exposure broaden the picture further. Akamai documented 150 billion API attacks from January 2023 through December 2024 and reported a 33% year-over-year rise in global web attacks. IBM’s 2024 breach research found that 40% of all breaches involved data distributed across multiple environments and that public-cloud breaches carried the highest average cost at USD 5.17 million. For utilities, the relevance is immediate: customer apps, AMI integrations, DER management interfaces, vendor APIs, and cloud-hosted support systems all add internet-facing control and data paths.

Supply Chain, Third-Party, and Remote Access Risk Statistics

Few categories have moved from secondary concern to board-level issue as quickly as supplier and remote-access risk. Verizon’s 2026 DBIR says third-party involvement rose 60% year over year and reached 48% of total breaches. That is a cross-industry figure, but it is especially relevant to utilities because they depend heavily on external maintenance, engineering support, telecoms, OEMs, cloud platforms, and managed service providers.

Claroty’s 2025 CPS survey strengthens that conclusion in operational environments. The survey found that 67% of respondents are reconsidering supply-chain geography, 73% are re-evaluating third-party remote access to CPS operations, and 46% said their organization experienced a breach in the last 12 months caused by third-party vendor access. It also found that 54% discovered security gaps or weaknesses in vendor contracts after incidents. As survey data, these figures are not utility-specific complaint counts, but they are highly relevant to energy and utility procurement teams.

Utilities should read these numbers as a procurement and architecture problem, not only a vendor-risk-management paperwork problem. The real controls sit in enforced MFA, brokered access, privilege boundaries, logging, session recording, asset-level access rules, contract language, and the removal of persistent vendor pathways that no longer serve a business need.

Regional and Regulatory Energy and Utilities Cybersecurity Statistics

The regulatory picture is increasingly regional, but the direction of travel is consistent. In the United States, NERC’s CIP standards remain the mandatory control spine for the bulk electric system, TSA continues to issue pipeline cybersecurity directives, and EPA has increased direct water-system cyber oversight. CISA’s Cross-Sector Cybersecurity Performance Goals are now part of the common language of critical-infrastructure risk reduction, and CISA’s 2025 adoption report said the strongest impact was visible in sectors including Water and Wastewater Systems.

In the European Union, NIS2 tightened cybersecurity obligations across critical sectors and explicitly covers energy, drinking water, and wastewater. ENISA and EUR-Lex materials also make clear that supply-chain risk management is now part of the expected control set, not an optional add-on. ENISA’s newer analyses continue to emphasize sector-specific implementation challenges tied to OT constraints, legacy systems, and cross-jurisdictional complexity.

For multinational operators, the practical implication is that “compliance maturity” should not be confused with “cyber resilience maturity.” Regulations are increasingly forcing energy and utility organizations to formalize controls around asset visibility, incident reporting, supply chain relationships, and security governance. The statistics in this article suggest that the organizations that benefit most will be those that use regulation to accelerate validation, not just documentation.

Leadership interpretation

What These Numbers Mean for Security Leaders

The statistics support a disciplined priority stack.

First, visibility still matters because it remains the prerequisite for every other control. If 40% of organizations in Claroty’s OT exposure study still had internet-connected OT assets, many defenses are failing before detection or response even begins. Asset inventory, service discovery, exposure review, and external attack-surface validation should therefore be treated as foundational work.

Second, utilities should assume that third parties and remote access are part of the core attack surface. The combination of Verizon’s 48% third-party breach involvement and Claroty’s 46% breach-via-third-party-access survey result is strong enough to justify tighter procurement controls, access brokering, session governance, contract reviews, and recurring access recertification.

Third, cloud, applications, and APIs are no longer secondary to critical infrastructure security. Utility portals, billing systems, mobile apps, and partner APIs often hold the keys to identity, payments, and customer operations. That makes API security testing, web application penetration testing, cloud penetration testing, and identity hardening practical control areas, not side projects.

Fourth, ransomware readiness needs to be tested rather than assumed. The available data supports investment in network segmentation, immutable and restoration-tested backups, detection engineering, tabletop exercises, and controlled red-team or penetration-testing programs focused on real attack paths. In OT-adjacent environments, testing should be carefully scoped, coordinated with operations, and designed to avoid production disruption.

Energy and utility organizations can use these findings to prioritize validation across internet-facing assets, cloud environments, APIs, customer portals, identity systems, network infrastructure, and safely scoped OT-adjacent environments. DeepStrike’s relevance in this context is practical rather than promotional: penetration testing, API penetration testing, cloud penetration testing, network testing, red team assessments, remediation tracking, and retesting support all fit naturally into a security-validation program based on exposure rather than assumptions.

Energy and Utilities Cybersecurity Benchmarking Checklist

Common Mistakes When Using Energy and Utilities Cybersecurity Statistics

The first mistake is scope inflation. Utilities-specific breach data, OT-wide telemetry, industrial ransomware leak-site counts, and internet-wide DDoS metrics cannot be treated as if they were measuring the same thing. They answer different questions and should stay separated in board papers and procurement memos.

The second mistake is category mixing. Energy, utilities, industrial, and critical infrastructure overlap, but they are not interchangeable labels. Water cybersecurity statistics should not be repackaged as energy-sector numbers, and industrial OT findings should not be presented as utility-only evidence without a clear caveat.

The third mistake is control-free storytelling. A long list of cyber numbers becomes marketing filler unless it leads to decisions about exposure management, segmentation, vendor access, application testing, cloud review, restoration testing, and executive reporting. Statistics are useful when they change priority, budget, or validation scope. They are not useful when they are used as dramatic decoration.

Buyer guidance and concluding analysis

FAQs

What are the most important energy and utilities cybersecurity statistics?

The most decision-useful figures are the ones that connect to real control priorities: Verizon’s utility-specific breach snapshot, FBI IC3’s critical-infrastructure complaint counts for energy and water, OT exposure data on internet-connected assets and KEVs, industrial ransomware counts for electric and oil-and-gas organizations, and current DDoS, API, and cloud-breach benchmarks. Together, those numbers speak to exposure, continuity, and recovery rather than just cyber volume.

Why are energy and utilities high-risk cybersecurity sectors?

Because they combine essential-service dependency, IT/OT convergence, public-facing digital services, supplier-connected operations, and systems that often cannot be patched or restarted on ordinary enterprise timelines. NIST’s OT guidance highlights the sector’s performance, reliability, and safety constraints, while current utility breach, ransomware, and OT-exposure statistics show that these are active attack surfaces, not just theoretical weaknesses.

What is the biggest cyber risk for electric utilities?

There is no single dominant risk, but the strongest data suggests utilities should focus on the combined effect of system intrusion, web-application exposure, social engineering, third-party access, and OT-adjacent continuity dependencies. Verizon’s utilities snapshot is especially useful here because it shows 94% of utility breaches clustering around a small set of recurring patterns.

How serious is ransomware for the energy sector?

Serious enough to treat as a continuity issue rather than only a malware issue. FBI IC3 continues to classify ransomware as one of the highest reported cyber threats to critical infrastructure, and Dragos documented sustained ransomware targeting across electric utilities, oil and natural gas, renewables, and water in 2025. The most important nuance is that operational disruption can happen even when the initial compromise stays on the IT side.

Why is OT cybersecurity important for utilities?

Because utility operations depend on OT for monitoring, control, and safe process execution. NIST SP 800-82 emphasizes the unique performance and safety requirements of OT, and current exposure research shows that exploitable weaknesses and internet-connected OT assets still exist at meaningful levels. That means utilities need controls and testing approaches that fit operational realities rather than simply copying IT playbooks.

What is the difference between IT and OT cybersecurity in utilities?

IT cybersecurity focuses heavily on confidentiality, user productivity, and enterprise data protection. OT cybersecurity has to account for process continuity, engineering workflows, safety, and the physical consequences of disruption. Fortinet’s 2025 survey is useful here because 60% of respondents reporting an intrusion said both IT and OT were impacted, showing that the boundary still matters even as the environments converge.

How do cloud, APIs, and IoT affect energy cybersecurity?

They expand the number of externally reachable workflows attached to utility operations. Customer portals, billing systems, AMI integrations, DER management tools, outage applications, and supplier workflows increasingly rely on cloud and API infrastructure. Akamai’s API attack volume and IBM’s multi-environment breach findings show why these technologies now belong inside energy-cybersecurity planning rather than beside it.

What cybersecurity frameworks apply to energy and utilities?

In the United States, NERC CIP applies to parts of the bulk electric system, TSA directives apply to covered pipelines, and EPA oversight has become more active in water. NIST SP 800-82 is a key reference for OT security, while CISA’s Cross-Sector Cybersecurity Performance Goals provide a practical baseline across critical infrastructure. In the EU, NIS2 extends cybersecurity obligations across sectors including energy, drinking water, and wastewater.

How should CISOs use energy cybersecurity statistics?

Use them to shape prioritization, not to replace diagnosis. Good statistics help justify asset visibility work, supplier-access reform, DDoS resilience, segmentation validation, application and API testing, cloud review, restoration testing, and executive reporting. They are most useful when tied to a clear scope statement and a change in control coverage or testing cadence.

How often should energy and utility organizations test security controls?

There is no universal annual number that safely fits every utility. Testing cadence should follow change rate and exposure: internet-facing portals and APIs need more frequent validation than static back-office systems, and OT-adjacent testing must be carefully scoped with operations. High-risk environments benefit from a layered cadence of vulnerability review, external testing, cloud and API testing, tabletop exercises, and periodic objective-based red-team work.

Conclusion

The strongest energy and utilities cybersecurity statistics point to a practical conclusion. Utility cyber risk is not concentrated in one threat class. It sits across ransomware, DDoS, OT/ICS and SCADA exposure, power-grid and service-availability risk, cloud and API dependencies, IoT and smart-grid expansion, and third-party access to critical environments. The best current data also shows that utilities-specific breach activity, industrial ransomware pressure, supplier-driven exposure, and internet-facing attack volume all remain material in 2026.

That is why energy and utilities cybersecurity statistics should guide security validation, not replace it. Organizations can use these findings to prioritize validation across internet-facing assets, cloud environments, APIs, customer portals, identity systems, network infrastructure, and safely scoped OT-adjacent environments. DeepStrike helps teams validate real-world exposure through penetration testing, API penetration testing, cloud penetration testing, network testing, red team assessments, remediation tracking, and retesting support.
