OVERVIEW
Source: Secondary Research, Interviews with Experts, MarketsandMarkets Analysis
The OT security market in Europe is estimated to increase from USD 5.70 billion in 2025 to USD 11.93 billion by 2030, at a CAGR of 15.9%. Growth will be driven by NIS2 compliance requirements, the rising frequency of cyberattacks targeting critical infrastructure, and increasing cybersecurity investments across the manufacturing, energy & power, utilities, and transportation sectors. Conversely, shortages of skilled labor in OT cybersecurity and legacy industrial systems are expected to constrain adoption. To address these challenges, European organizations are expanding investments in training, managed services, and incident response capabilities while also forming partnerships with OT cybersecurity vendors and systems integrators to strengthen compliance and operational resilience.

COMPETITIVE LANDSCAPE - KEY PLAYERSSiemens, Schneider Electric, ABB, and Thales lead the Europe OT security market through strong integration of cybersecurity within industrial automation and critical infrastructure systems. Vendors such as Claroty, Darktrace, and Rhebo strengthen the landscape by offering OT visibility, anomaly detection, and threat monitoring across manufacturing, energy, utilities, and transportation sectors.
-
COMPETITIVE LANDSCAPE - STARTUPSTXOne Networks, Stormshield, and Cylus represent emerging players in the European OT security ecosystem. These vendors focus on OT-specific endpoint and network protection, with an emphasis on simplified deployment and security for distributed and safety-critical industrial environments.
Alongside platform modernization, European utilities, energy operators, manufacturers, transportation agencies, and public infrastructure entities are increasingly spending on OT security services. Demand for managed monitoring, automated anomaly detection, and incident response is increasing with the need to fill internal skill gaps and meet the resilience requirements of NIS2; therefore, increasing orders from organizations to lower their operational risk and meet compliance, and the rise in the use of OT automation, AI-based telemetry and continuous monitoring, boosts the continuing establishment of the OT security market in Europe.
TRENDS & DISRUPTIONS IMPACTING CUSTOMERS' CUSTOMERS
The Europe OT security market is shifting from standalone firewalls and on-premises tools toward integrated visibility platforms, zero-trust architectures, and automated anomaly detection. Demand is rising for secure OT data exchange, identity and access management, and remote access protection, driven by increasingly stringent regulatory requirements, such as NIS2. Industrial operators are modernizing legacy systems to enhance asset visibility, safety, and incident response, thereby creating demand for scalable OT security platforms across the manufacturing, energy, utilities, and transportation sectors. Traditional solutions such as legacy OT firewalls, network segmentation, and access gateways are giving way to advanced platforms that emphasize unified OT asset visibility, zero-trust architectures, autonomous threat analytics, AI-assisted incident response, and managed OT detection and response services. These capabilities address the requirements of end-user industries—including energy and utilities, oil and gas, manufacturing, transportation, water infrastructure, and smart buildings—by delivering outcomes such as enhanced safety and uptime, improved regulatory compliance, threat protection, automated detection and remediation, and transparent asset inventory. Collectively, the shift highlights how evolving use cases and client expectations are reshaping revenue models across the OT security ecosystem.

Driver: Increasing investment in OT security due to NIS2 and national critical infrastructure regulations
The implementation of NIS2 and country-specific critical infrastructure regulations is a key driver for the Europe OT security market. These regulations require operators in the energy, utilities, transportation, manufacturing, and public services sectors to strengthen their cyber resilience and incident preparedness. As a result, organizations are increasingly investing in OT visibility, monitoring, and compliance-focused security controls to meet regulatory obligations.
Restraint: High cost and complexity of securing legacy ICS and SCADA systems
Many European industrial environments depend on outdated, legacy ICS and SCADA systems that have no native protections because they are costly, complicated to set up, and there are not many ways to keep them up-to-date. Companies face high costs associated with upgrading these systems because there is a limited ability to patch these systems, operate them using proprietary protocols, and deal with safety requirements. These issues have slowed down the implementation of modernization strategies, as well as other organizations' ability to implement large-scale, leading-edge OT security solutions.
Opportunity: Growing demand for managed OT security and incident response services
European organizations are shifting toward managed OT security and incident response services to address internal skill gaps and compliance requirements. These services enable continuous monitoring and faster response without disrupting operations. This trend is creating strong growth opportunities for service providers supporting regulated and multi-site industrial environments.
Challenge: Integration issues across heterogeneous industrial and safety systems
Industrial operations across Europe involve a diverse range of PLCs, safety systems, and vendor-specific technologies deployed across multiple sites and countries. Integrating consistent security controls across these heterogeneous environments remains difficult. Organizations must ensure cybersecurity measures do not impact safety, reliability, or uptime, making OT security implementation complex.
