Utility Cybersecurity Market Size, Share & Growth Forecast (2026-2031)

The Utility Cybersecurity Market is forecast to grow at a CAGR of 9.0%, reaching USD 11.69 billion in 2031 from USD 7.58 billion in 2026.

The utility cybersecurity market is evolving away from a narrow enterprise cybersecurity focus towards an expansive critical-infrastructure protection ecosystem providing coverage for electricity, natural gas, water, wastewater, sewage, and other core utility operations.

Utility infrastructure is increasingly digital. Smart meters, digital substations, distribution automation, DER-management platforms, Battery systems, and EV charging infrastructure are implemented by electricity providers. In addition to this, electricity providers incorporate remote-control technologies. Gas utilities use technology like connected pipeline monitoring, compressor controls (remote terminal units), metering systems, and SCADA networks. Millions of general-purpose remote sensors, automated treatment controls, digital pumping systems, telemetry, and cloud-connected monitoring are being implemented at several water utilities.

While digitalization allows for greater operational efficiencies and visibility, it also increases the cybersecurity attack surface. Increasing cyberattacks on public water systems threaten their reliability, with a report from the U.S. Environmental Protection Agency (EPA) indicating that utilities need to be prepared to plan for, make early responses to, and recover from incidents impacting them.

As a result, the market is evolving around a layered architecture where network security acts as the base layer of protection, while endpoint security, application security, data security, identity management, vulnerability management, and managed cybersecurity services.

Another big factor is the move towards IT/OT convergence. As per Cisco's utility research, utilities are challenged with finding assets, increasing asset digital risk due to technology transformations, volume of legacy infrastructure remaining with few human resources losing knowledge rapidly. This is all compounded by challenging energy and electricity supply issues currently forcing regulatory pressure. As a result, a major market need arises as utilities must upgrade their infrastructure and expand connectivity without introducing cyber vulnerabilities that could disrupt critical services.

Utility Cybersecurity Market Key Highlights

Market Dynamics

Market Drivers

• Increasing Digitalization of Utility Infrastructure: More utility operators are rolling out digital substations, smart meters, SCADA modernization, automated distribution networks, remote sensors, connected field devices, cloud applications, and centralized monitoring platforms. While digital transformation multiplies the amount of operational data available for utilities, it also increases the number of endpoints and communication pathways needing to be defended. Hence, with the continuous rise of utility digitalization, cybersecurity investment follows in the market.

• Increased Cyber Warfare against Critical Infrastructure: The operational systems and services those systems provide are appealing targets for ransomware groups, financially motivated attackers, hacktivists, and nation-state actors. Energy infrastructure has become a highly selected and attractive high-value target.SentinelOne explains that threats target generation, transmission, and distribution, pipelines, substations, and distributed energy infrastructure. The escalating impacts of disruptions in utilities drive operators to invest actively in prevention, detection, containment, and recovery capabilities.

• Cybersecurity Vulnerabilities in Water Utilities: Water and wastewater utilities are creating a growing demand center for cybersecurity, with treatment, pumping, chemical management, telemetry, and distribution operations becoming more reliant on connected control systems. In August 2025, the EPA announced over $9 million in grant funding to support efforts by midsize and large drinking water systems to assess cybersecurity threats. These growing programs are raising the visibility of cybersecurity as an operational challenge, not just an optional IT investment.

• Increasing IT/OT Integration: Providers are integrating applications with operational technologies (OT), including SCADA, PLCs, RTUs, intelligent electronic devices (IEDs), industrial communications networks, and distributed control systems. With the emergence of these technologies, utility operations are becoming even more interlaced with enterprise applications. According to Cisco, the need for more IT/OT collaboration is apparent for utilities because independent networks can obstruct cybersecurity. This is driving the requirement for unified visibility, identity management, segmentation, threat detection, and orchestrated incident response, which in turn is bolstering demand for integrated cybersecurity platforms.

Market Restraints & Opportunities

• Most utility assets have long operating lifecycles and were not originally designed with enterprise-level cybersecurity capabilities. Thus, utilities need cybersecurity solutions that will safeguard existing equipment without requiring them to refit their infrastructure immediately.

• A full-scale cybersecurity program includes spending on security hardware/software, personnel, evaluations, managed services, monitoring platforms, incident response and remediation planning, compliance auditing, and employee training.

• The scarcity of specialized OT cybersecurity professionals is making outsourcing services like managed security services, security operations centre, vulnerability assessment and incident response, as well as continuous monitoring seem more attractive.

• The increasing amount of network, endpoint, identity, and operational telemetry is producing new avenues for AI-driven cybersecurity analytics. Detection powered by AI helps utilities to minimize the volume of alerts and detect abnormal behavior on dispersed infrastructure.

Key Developments

• August 2026: Industrial Defender and Fortress Information Security combined their respective OT cybersecurity platforms to accelerate vulnerability discovery and mitigation for critical-infrastructure operators.

• May 2026: NexusTek introduced a managed IT and cybersecurity practice for US mid-market energy, oil-and-gas, utility, and renewable-energy organizations.
