Global Gas OT Cybersecurity Market Outlook, 2031

Gas operational technology cybersecurity has moved from a specialist engineering concern to a board-level regulatory obligation, and the perimeter of the market is now defined less by software categories than by the enforceable outcomes that regulators require operators to demonstrate. The TSA Security Directive Pipeline-2021-01E, effective May 3, 2025, and expiring May 2, 2026, continues the requirements first issued in May 2021 for designated hazardous liquid and natural gas pipeline operators and LNG facilities. The directive requires covered operators to report cybersecurity incidents to CISA, designate a Cybersecurity Coordinator available twenty-four hours a day, seven days a week, develop network segmentation policies ensuring that the OT system can continue to safely operate if an IT system is compromised, implement access control measures preventing unauthorised access to critical cyber systems, build continuous monitoring and detection capabilities, and apply security patches for operating systems, applications, drivers, and firmware using a risk-based methodology. Operators must also establish and execute a TSA-approved Cybersecurity Implementation Plan describing the specific measures used to achieve the directive’s security outcomes, and maintain a Cybersecurity Incident Response Plan. The European regulatory layer has tightened in parallel. NIS2 explicitly regulates SCADA systems, industrial control centres, and smart distribution facilities as covered components, and its Article 21 risk-management measures apply to gas supply undertakings, transmission system operators, and distribution system operators without an OT carve-out. Article 23 imposes a staged incident-reporting chain: an early warning within twenty-four hours of awareness, a full notification within seventy-two hours, and a final report within one month. The international technical framework is anchored by IEC 62443, whose zone-and-conduit model provides the architecture for achieving the segmentation that TSA and NIS2 require, and by API Standard 1164, now in its third edition, which expanded from a SCADA-specific standard to cover all pipeline control system cybersecurity across five domains and 108 controls.

The manufacturing and development base is led by OT-native security specialists with pipeline-specific deployments and threat-intelligence capability. Dragos provides the Dragos Platform for real-time visibility into critical systems and validation of segmentation policies across OT networks, positioned explicitly to help pipeline operators exceed TSA Security Directive Pipeline-2021-02F requirements, and its Neighborhood Keeper collective-defense capability is deployed in Amazon Web Services to share threat intelligence across participating operators without requiring proprietary technology. Nozomi Networks supplies passive, non-intrusive visibility across ICS and SCADA environments, including geographically separated plants, and its SCADAguardian appliance installs in OT networks passively with no downtime; the company’s technology is used in more than 400 gas distribution substations globally, and its Arc Embedded sensor was integrated into Schneider Electric’s SCADAPack 47xi Smart RTUs to provide visibility at the control-device layer. Claroty serves nearly sixty percent of the world’s fifty leading oil and gas refineries and pipeline operators, and its threat-management solutions have been deployed across twelve refineries, three midstream facilities, one SCADA system, and a centralised enterprise management console in a joint engagement with Rockwell Automation. Siemens, Schneider Electric, ABB, Honeywell, and Cisco provide integrated automation and network-security architectures that embed segmentation and access control within the control system itself. SANS Institute’s Five ICS Cybersecurity Critical Controls, an OT-specific incident response plan, a defensible architecture, ICS network visibility and monitoring, secure remote access, and risk-based vulnerability management provide the practitioner framework that Dragos and other vendors map their offerings against. These participants compete on passive-detection fidelity, protocol breadth, segmentation validation, threat-intelligence depth, and the ability to produce regulatory evidence without disrupting gas flow.

Market Dynamics

Market Drivers • TSA Directive Renewal and the Conversion of Cybersecurity into Enforceable Outcomes: The most powerful driver across the global gas OT cybersecurity market is the conversion of pipeline cybersecurity from voluntary guidance into directive obligations with defined outcomes and a recurring renewal cycle. SD Pipeline-2021-01E does not prescribe specific technologies; it requires operators to achieve network segmentation that allows safe OT operation if IT is compromised, to implement access controls, to build continuous monitoring and detection capabilities, and to apply risk-based patching. The requirement to maintain a TSA-approved Cybersecurity Implementation Plan and a Cybersecurity Incident Response Plan makes the operator’s security posture auditable rather than asserted. The directive’s annual renewal 01E superseded 01D and carries a May 2, 2026 expiration prevents operators from treating compliance as a one-time project, and the PIPES Act of 2025 directs TSA to codify the standards introduced after the Colonial Pipeline incident, signalling that the directive framework will become permanent rather than episodic.
• Threat Escalation and the Colonial Pipeline Precedent: The threat environment that these regulations respond to has deteriorated materially. Ransomware attacks targeting the oil and gas industry increased 935 percent between April 2024 and April 2025, and sixty-seven percent of energy organisations were hit in 2024. The Colonial Pipeline incident in May 2021 remains the defining precedent: DarkSide ransomware breached the IT environment through a compromised VPN account lacking multi-factor authentication, and Colonial shut down 5,500 miles of pipeline operations for nearly a week because it lacked visibility into whether the attack had crossed into OT, resulting in gasoline shortages across seventeen states. The OT network was never compromised; the shutdown was a consequence of uncertainty about the IT/OT boundary. This precedent is the direct justification for TSA’s segmentation and monitoring requirements, and it explains why gas operators treat visibility into the IT/OT boundary as a safety obligation rather than an IT convenience. The DESFA incident in Greece, where Ragnar Locker ransomware affected IT infrastructure and prompted proactive deactivation of most IT services, reinforced the pattern: IT-origin attacks on gas operators create operational risk even when OT is not directly breached.

Market Challenges • The Segmentation Assertion Gap and the Limits of Network Visibility: A persistent technical challenge in gas OT cybersecurity arises from the gap between documented segmentation and actual network behaviour. Dragos reports that eighty-eight percent of its service engagements find poor security perimeters and weak segmentation, and Nozomi Networks reports that eighty percent of the facilities it visits lack updated asset lists and network mapping for their OT infrastructure. TSA requires segmentation policies that ensure the OT system can continue to safely operate if IT is compromised, but many gas SCADA architectures evolved incrementally, with monitoring and control networks retrofitted over decades, and the segmentation that exists in architecture diagrams may not reflect actual data flows between field devices, control centres, and enterprise systems.
• Legacy Protocols, Remote Access, and the Operational Disruption Constraint: OT security deployments in gas networks must contend with legacy protocols, insecure remote connectivity, and the operational constraint that security tools cannot disrupt live gas flow. Nozomi Networks identifies insecure and hijacked remote connectivity, well-known vulnerabilities in systems designed without security in mind, internet-connected control systems, and widely published technical specifications as evergreen risks in oil and gas pipelines. Multi-factor authentication, secure remote access, and data diodes help enforce one-way flows of operational data without opening inbound paths, but retrofitting these controls onto legacy RTUs and SCADA platforms requires careful engineering to avoid disrupting the very operations the security controls are meant to protect.



Market Trends • Passive Monitoring, Asset Discovery, and Segmentation Validation: The market is shifting from perimeter-based prevention toward continuous, passive visibility as the foundation of OT security. Nozomi Networks’ SCADAguardian installs passively in OT networks with no downtime, providing real-time cybersecurity and operational visibility without adding latency or disrupting live operations. Dragos provides real-time visibility into critical systems and validates segmentation policies across OT networks, and its platform can be deployed in virtualised, on-premises, or cloud-based environments. Schneider Electric embedded Nozomi Arc within its SCADAPack 47xi Smart RTUs, giving security and operations teams visibility at the control-device layer for the first time, with the ability to analyse and deter user activity without impacting current resources or disrupting mission-critical networks. This trend favours OT-native platforms with deep protocol coverage and passive-detection fidelity over IT-security tools adapted for OT, because the value proposition is safe visibility into environments where active scanning is unacceptable.
• Collective Defence and Threat-Intelligence Sharing: The market is witnessing the emergence of collective-defence models that allow gas operators to share threat intelligence without exposing sensitive operational data. Dragos Neighborhood Keeper is deployed in Amazon Web Services and enables participating operators to benefit from collective visibility into adversary activity across the community, without requiring proprietary technology or sharing sensitive details about their own networks. This trend responds to the asymmetry between sophisticated, state-linked adversaries and individual pipeline operators, and it aligns with the CISA Pipeline Cybersecurity Initiative’s emphasis on voluntary assessments and collaboration aimed at hardening OT environments. The model is particularly relevant for mid-sized and municipal gas operators that lack the threat-intelligence capability of large transmission companies.

Segmentation Analysis

Network security dominates the global market’s regulatory-driven value because the segmentation, access control, and boundary enforcement that TSA and NIS2 require are fundamentally network-layer capabilities, and because the Colonial Pipeline precedent established that uncertainty about the IT/OT boundary is itself an operational risk. • The global gas OT cybersecurity market is segmented by solution type into network security, endpoint and access security, security monitoring and detection, and cybersecurity services. Network security represents the dominant layer because the enforceable outcomes that regulators require segmentation that allows safe OT operation if IT is compromised, and access controls preventing unauthorised access are achieved through network architecture and policy.
• IEC 62443’s zone-and-conduit model provides the technical framework for network security in gas OT environments, grouping assets with common security requirements into zones and controlling traffic between zones through conduits with defined security policies. Security levels SL 1 through SL 4 define increasing resistance to circumvention, and gas pipeline operators typically target SL 2 or SL 3 depending on the consequence of compromise.
• Network security deployments in gas networks must enforce one-way data flows from OT to IT where possible, using data diodes and unidirectional gateways, while permitting controlled bidirectional flows for maintenance and remote operations under strict access controls.
• Endpoint and access security represents a substantial and growing layer, encompassing secure remote access, multi-factor authentication, privileged access management, and endpoint hardening for RTUs, flow computers, and engineering workstations. TSA’s access-control requirement and NIS2’s Article 21 measures make this a mandatory rather than discretionary investment.
• Security monitoring and detection represents the fastest-growing solution segment, driven by TSA’s continuous-monitoring requirement and by the threat-intelligence imperative illustrated by Colonial. Passive monitoring platforms from Dragos, Nozomi, and Claroty provide the visibility layer, while AI-enhanced anomaly detection flags unusual commands or traffic patterns before they escalate.

Security monitoring and detection is the fastest-growing solution segment globally because continuous monitoring is the capability that converts segmentation from an architectural assertion into an operational reality, and because the Colonial precedent demonstrated that detection gaps create shutdown risk even when OT is not breached. • By solution type, security monitoring and detection encompasses passive network monitoring, asset discovery, anomaly detection, intrusion detection, and security information and event management integration for OT environments.
• The SANS Five ICS Cybersecurity Critical Controls identify ICS network visibility and monitoring as a core control, alongside an OT-specific incident response plan, a defensible architecture, secure remote access, and risk-based vulnerability management, providing a practitioner framework that monitoring vendors map their capabilities against.
• CISA’s Pipeline Cybersecurity Initiative complements regulatory mandates through voluntary assessments and collaboration aimed at hardening OT environments, and its guidance emphasises strong perimeter controls to isolate ICS and SCADA systems from corporate networks and the internet.
• Dragos Neighborhood Keeper enables collective threat intelligence sharing across participating operators, and Nozomi Networks’ deployment in more than 400 gas distribution substations demonstrates the scale at which passive monitoring is being operationalised in gas networks.
• Cybersecurity services represent a substantial and recurring layer, spanning incident response, tabletop exercises, regulatory audit support, and managed detection and response. TSA’s requirement for a Cybersecurity Incident Response Plan and NIS2’s Article 23 reporting chain create demand for services that help operators demonstrate readiness before an incident occurs.

Pipeline and SCADA systems are the largest application segment globally because they concentrate the highest-value control-room assets, the most explicit TSA and PHMSA obligations, and the longest communication spans requiring segmentation and monitoring. • By application, pipeline and SCADA systems represent the dominant share, encompassing transmission pipeline SCADA, compressor-station telemetry, city-gate monitoring, and control-room operations subject to TSA’s pipeline security directives and PHMSA’s control room management rule.
• The Colonial Pipeline incident is the defining case for this segment: a ransomware attack on IT systems prompted a precautionary shutdown of 5,500 miles of pipeline because the operator could not otherwise be certain about the boundary between environments.
• Gas distribution control systems represent a substantial and growing application segment, where OT cybersecurity must extend to district regulating stations, CNG facilities, and smart-metering infrastructure. Nozomi Networks’ technology is deployed in more than 400 gas distribution substations globally, and Schneider Electric’s embedded Arc sensor in SCADAPack RTUs addresses the distributed field-asset layer.
• Gas processing and LNG facilities represent a specialised but high-consequence application segment, where OT cybersecurity must address process-safety obligations, compressor and safety-system integration, and the cybersecurity requirements of IEC 62443 zones and conduits. DESFA’s disclosure of a Ragnar Locker ransomware attack affecting IT infrastructure illustrates the operational risk that IT-origin attacks pose to gas processing and transmission operators even when OT is not directly breached.

Gas utilities are the largest end-user segment globally because they own the distribution and transmission infrastructure subject to TSA and NIS2 obligations, and because they bear the operational and regulatory consequence of an IT/OT boundary failure. • By end user, gas utilities represent the dominant share, encompassing transmission system operators, distribution system operators, and integrated gas utilities that operate SCADA systems subject to TSA directives and NIS2 requirements.
• NIS2 explicitly scopes gas supply undertakings, transmission system operators, and distribution system operators as essential entities, applying Article 21 risk-management measures and Article 23 incident-reporting obligations without an OT exception.
• Pipeline operators represent the second core end-user group, where TSA’s Security Directive Pipeline-2021-01E applies to designated hazardous liquid and natural gas pipeline operators and LNG facilities, requiring segmentation, access control, continuous monitoring, and risk-based patching.
• Gas processing and LNG operators represent a specialised end-user segment, where OT cybersecurity must address the convergence of process-safety systems, compressor controls, and safety instrumented systems, and where the consequence of a cyber-physical event is measured in containment loss and safety-system failure rather than in commercial disruption alone.

Regional Analysis

North America leads in directive-driven OT cybersecurity specification because TSA Security Directive Pipeline-2021-01E, the PIPES Act’s codification direction, and the Colonial Pipeline precedent create an enforceable and continuously renewed compliance architecture, while Europe leads in NIS2-driven risk-management and incident-reporting obligations, and Asia-Pacific grows with gas infrastructure expansion and the adoption of IEC 62443 as a procurement standard. • North America is the most prescriptive market for gas OT cybersecurity, with TSA’s directive requiring network segmentation, access control, continuous monitoring, risk-based patching, a TSA-approved implementation plan, and an incident response plan, and with the directive’s annual renewal preventing compliance from becoming a one-time exercise. The Colonial Pipeline precedent and the 935 percent surge in oil and gas ransomware attacks sustain urgency, and the region’s dense transmission and distribution networks, LNG terminals, and compressor-station density create a large addressable base for monitoring, segmentation, and services.
• Europe is shaped by NIS2’s explicit regulation of SCADA systems, industrial control centres, and smart distribution facilities, with Article 21 risk-management measures and Article 23’s twenty-four-hour early warning, seventy-two-hour notification, and one-month final-report obligations. European operators must layer NIS2 requirements on top of existing sector-specific standards, and the EU CER Directive adds continuous third-party software risk reporting for energy operators.
• Asia-Pacific is a growth-driven market tied to gas infrastructure expansion, city gas distribution digitalisation, and the adoption of IEC 62443 as a procurement standard by national energy regulators and major operators. Regulatory frameworks are developing, and OT cybersecurity specification is often driven by operator standards, EPC requirements, and multilateral development finance rather than by a single harmonised regional mandate.
• The Middle East and Africa are project-driven markets concentrated in transmission, LNG, and processing facility cybersecurity, where OT security is specified alongside control-system modernisation and where international standards and operator specifications dominate procurement. Latin America shows moderate growth potential, with OT cybersecurity adoption tied to regulatory modernisation, critical-infrastructure designation, and the need to secure ageing gas infrastructure against ransomware and state-linked threats.
