Cybersecurity for Utilities and Critical Infrastructure
THOR Security Group helps electric cooperatives, water and wastewater districts, and gas companies reduce cyber risk, protect the operational technology behind essential services, prepare for incidents, and build practical, defensible cybersecurity programs.
How THOR Helps Utilities and Critical Infrastructure Strengthen Cybersecurity
Utilities keep the lights on, the water safe, and the gas flowing. Electric cooperatives, municipal utilities, water and wastewater districts, and natural gas providers operate the critical infrastructure that entire communities depend on every hour of every day.
That responsibility makes them a high-value target.
Utilities face ransomware, business email compromise, credential theft, and a growing volume of attacks aimed at operational technology — the control systems behind generation, distribution, treatment, and delivery. A successful attack can threaten public safety, disrupt essential services, trigger regulatory scrutiny, and create significant recovery costs. At the same time, many utilities must manage cybersecurity with limited staff, aging control systems, constrained budgets, and a complex mix of IT and OT environments.
THOR Security Group helps utilities strengthen cybersecurity through executive security leadership, managed protection, cybersecurity assessments, incident response guidance, vendor oversight, and measured risk management.
With more than 20 years of technology, cybersecurity, compliance, and leadership experience, THOR helps cooperatives, districts, and utility providers understand current risk, protect critical systems, prioritize improvements, and build cybersecurity programs that support reliable service delivery.
The Challenge: Where IT Risk Meets Operational Safety
For utilities, cybersecurity is not only an IT issue. It is an operational, safety, regulatory, financial, and public-trust issue. The same network that runs email and billing increasingly connects to the systems that run physical operations.
A cyber incident at a utility can affect:
- Generation, distribution, and grid operations
- Water treatment, pumping, and wastewater systems
- Gas distribution and pressure controls
- SCADA, ICS, and remote telemetry
- Outage management and dispatch
- Member and customer billing
- Metering and AMI infrastructure
- Email, identity, and Microsoft 365
- Member and resident data
- Backup and recovery operations
- Vendor-hosted and cloud systems
Many utilities rely on a mix of internal staff, outsourced IT providers, control-system integrators, equipment vendors, cloud platforms, and legacy systems that were never designed to be connected. That makes it hard for leadership to know who is responsible for security, where the most important risks are, and what to fix first — especially across the boundary between IT and operational technology (OT).
THOR helps bring structure, visibility, and practical guidance to that environment.
How THOR Supports Utilities and Cooperatives
THOR works with utilities across executive leadership, managed protection, OT and SCADA security, assessments and remediation, ransomware and incident readiness, vendor and supply-chain risk, and vulnerability management — delivered as project-based consulting, fractional CIO/CISO leadership, managed security support, or an ongoing advisory relationship.
Managed Protection
Ongoing threat monitoring, MDR oversight, and security operations support that keep utility systems and member services defended around the clock.
Learn moreOT, ICS & SCADA Security
Protect the operational technology behind power, water, and gas delivery — IT/OT segmentation, monitoring, and access control that doesn't disrupt service.
Learn moreSecurity Assessments
Risk and ransomware-readiness reviews — including AWIA-style risk and resilience evaluations — that turn findings into prioritized, budget-aware action.
Learn moreFractional CIO & CISO
Executive security and technology leadership — governance, board reporting, and roadmaps — without the cost of a full-time hire.
Learn moreVulnerability Management
Continuous scanning, prioritization, and remediation tracking across legacy and modern systems on both the IT and OT sides.
Learn moreIncident Response
Guidance for ransomware, BEC, and account compromise — contain risk and restore essential services with confidence when minutes matter.
Learn moreProtecting Operational Technology (OT, ICS & SCADA)
The systems that run physical operations — SCADA, industrial control systems, programmable logic controllers, and remote telemetry — were built for reliability and long service life, not for today's threat landscape. As these environments connect to corporate networks and the internet, the attack surface grows.
THOR helps utilities reduce OT risk with a practical, safety-first approach that prioritizes uptime and service continuity. This commonly includes helping leadership and operations teams work through questions such as:
- Is the IT network properly segmented from OT and control systems?
- Are remote-access pathways into OT secured and monitored?
- Are control systems inventoried, and is their exposure understood?
- Are vendor and integrator connections governed and logged?
- Is there monitoring that spans both the IT and OT sides?
- Are legacy systems compensated for where patching isn't possible?
- Is there a tested plan to operate and recover if systems go down?
The goal is not to bolt enterprise security onto fragile control systems — it is to reduce real risk while respecting the operational realities of running critical infrastructure.
Ransomware Readiness and Incident Response
Ransomware is one of the most serious risks facing utilities. An incident can disrupt operations, threaten public safety, delay billing and payments, and create significant recovery and regulatory costs.
THOR helps utilities improve ransomware readiness by reviewing backup strategy, endpoint protection, access controls, patching practices, remote access, Microsoft 365 security, IT/OT segmentation, vendor dependencies, and incident response procedures. This includes helping leadership answer practical questions such as:
- Are critical IT and OT systems backed up and recoverable?
- Have backups and recovery procedures been tested?
- Are administrative and privileged accounts protected with MFA?
- Are remote-access pathways into the environment secured?
- Can operations continue safely if control systems are unavailable?
- Does the team know what to do in the first hour of an incident?
- Are vendors, legal counsel, insurers, regulators, and leadership roles clearly defined?
- Is there a plan to communicate with members, residents, and officials?
THOR also provides incident response guidance when suspicious activity, ransomware, business email compromise, or unauthorized access occurs — helping utilities contain risk, coordinate the right resources, and restore essential services with confidence.
Regulatory and Compliance Alignment
Utilities operate under a patchwork of cybersecurity expectations that vary by sector, size, and regulator. THOR helps you understand which apply to your organization and build a program that aligns with them — without drowning in paperwork.
- Electric — NERC CIP for bulk-electric-system assets, RUS/USDA expectations for cooperative borrowers, and industry best practices for distribution utilities
- Water & wastewater — EPA expectations and America's Water Infrastructure Act (AWIA) risk and resilience assessments and emergency response plans, plus AWWA cybersecurity guidance
- Natural gas & pipelines — TSA security directives and pipeline security guidance where applicable
- Cross-sector — CISA recommended practices and the NIST Cybersecurity Framework as a common backbone
THOR helps utilities review controls, document remediation, and develop practical roadmaps that support audits, cyber insurance renewals, and cybersecurity grant requirements. The emphasis is always on real risk reduction first, with documentation that follows.
Managed Protection for Utilities
Cybersecurity is not a one-time project. Utilities need ongoing visibility, monitoring, and support to maintain a strong security posture across both IT and OT.
THOR's managed protection services help utilities improve and maintain security through practical security operations support — threat monitoring, MDR oversight, SIEM/XDR guidance, vulnerability management, Microsoft 365 security review, endpoint coordination, incident response planning, and recurring leadership reporting. Managed protection can help utilities:
- Identify security issues earlier
- Improve ransomware resilience
- Strengthen visibility across IT and OT
- Reduce dependence on reactive support
- Support cyber insurance readiness
- Improve documentation for leadership, auditors, and regulators
- Clarify responsibilities between staff, MSPs, integrators, and vendors
- Maintain a continuous improvement model
- Provide practical reporting to boards, members, and leadership
Cybersecurity Assessments and Remediation Planning
A strong cybersecurity program begins with understanding current risk.
THOR performs cybersecurity assessments designed to help utilities identify weaknesses, prioritize remediation, and communicate risk clearly to leadership. These may include:
- Cybersecurity risk assessments
- Ransomware readiness assessments
- Risk and resilience reviews aligned to AWIA-style expectations
- IT/OT segmentation and exposure review
- Microsoft 365 and Azure configuration reviews
- Vulnerability scanning, external and internal
- Vendor due diligence
- Security roadmap development
The deliverable is not just a technical list of issues. THOR focuses on practical, executive-ready recommendations that help leadership decide what to fix first, what to budget for, and how to reduce risk over time.
Vendor and Supply-Chain Risk Management
Utilities depend on equipment manufacturers, control-system integrators, software vendors, billing and metering providers, managed IT services, and cloud platforms. Each connection can introduce cybersecurity risk if responsibilities are not clearly defined — and OT vendors often hold remote access into the most sensitive systems.
THOR helps utilities review vendor and supply-chain risk by evaluating security responsibilities, remote-access requirements, data handling, incident notification expectations, contract alignment, and documentation. Common areas of focus include:
- Vendor and integrator access to IT and OT systems
- Remote-access controls and monitoring
- Data handling and retention practices
- Incident notification procedures
- Backup and recovery responsibilities
- Contract and service-level alignment
- Security responsibility boundaries
- Vendor risk ranking and prioritization
This gives leadership a clearer understanding of which third parties create risk, what controls are expected, and where additional oversight is needed.
Fractional CIO and CISO Leadership
Not every utility or cooperative needs or can justify a full-time CIO or CISO. But many still need executive-level technology and cybersecurity leadership — especially as IT and OT converge.
THOR provides fractional CIO and CISO services to help utilities make better technology, security, vendor, compliance, and risk decisions without the cost of a full-time executive hire. Fractional leadership can support:
- Cybersecurity governance and board reporting
- Security roadmap development
- IT and OT strategy
- Vendor and integrator management
- Oversight of internal IT teams and MSP relationships
- Incident response planning
- Policy and procedure review
- Regulatory and grant readiness
- Cyber insurance readiness
- Budgeting and prioritization
This gives utilities access to experienced leadership on a right-sized basis.
Example Engagement: From Risk Assessment to Managed Protection
Illustrative example only — not a specific named client engagement.
A cooperative or district may come to THOR after a cyber insurance questionnaire, a regulatory expectation, a ransomware concern in the sector, recurring vulnerability findings, or board-level questions about cybersecurity readiness.
The engagement may begin with a review of current policies, technical controls, IT/OT segmentation, Microsoft 365 configuration, vendor and integrator relationships, backup and recovery practices, vulnerability management, remote access, and incident response procedures. From there, THOR may help the organization:
- Identify cybersecurity gaps and high-risk exposures across IT and OT
- Prioritize remediation based on operational and safety risk
- Clarify responsibilities between staff, MSPs, integrators, and vendors
- Strengthen IT/OT segmentation and remote-access controls
- Improve backup and recovery readiness
- Develop a ransomware readiness and incident response plan
- Align the program with applicable regulatory expectations
- Build board and leadership reporting
- Establish ongoing managed protection and security oversight
- Prepare for audits, insurance reviews, and grant requirements
The result is a more organized, defensible, and sustainable cybersecurity program that protects essential services.

Utility cybersecurity FAQs
What cybersecurity regulations apply to utilities?
It depends on your sector and size. Electric utilities may fall under NERC CIP, and cooperative borrowers under RUS/USDA expectations; water and wastewater systems have EPA and America's Water Infrastructure Act (AWIA) risk-assessment requirements and follow AWWA guidance; natural gas and pipeline operators may be subject to TSA security directives. We help you identify and align with the ones that apply.
Do you work with electric cooperatives, water districts, and gas companies?
Yes — we support rural electric cooperatives, municipal utilities, water and wastewater districts, and natural gas providers, scaling the program to your size, systems, and regulatory profile.
Can you help protect OT, ICS, and SCADA systems?
Yes. We focus on the IT/OT boundary — segmentation, secured and monitored remote access, asset visibility, and controls that reduce risk without disrupting the operational systems that deliver essential services.
Why are utilities targeted by attackers?
As critical infrastructure, utilities face ransomware, opportunistic, and nation-state threats. Because a disruption can affect public safety and essential services, the stakes — and attacker interest — are higher than for many other organizations.
Can you support grant and cyber insurance requirements?
Yes — assessments, documented controls, and managed protection help with cyber insurance renewals, audits, and cybersecurity grant expectations.
