The expansion of connected OT assets, remote engineering access, and industrial IoT deployments is creating greater vulnerability across legacy SCADA and ICS environments that were not originally designed with embedded cybersecurity controls. At the same time, rising ransomware attacks targeting operational downtime and production disruption are pushing organizations to invest in industrial visibility, anomaly detection, network segmentation, and secure access solutions to strengthen operational resilience and ensure uninterrupted industrial processes.

"By solution, the identity & access management (IAM) segment is expected to witness the highest CAGR during the forecast period."
The identity & access management (IAM) segment is expected to witness the fastest growth in the OT security market due to increasing concerns around unauthorized access to critical industrial systems and remote operational environments. Industrial organizations are increasingly adopting IAM solutions to secure operator credentials, privileged accounts, third-party vendor access, and remote maintenance activities across ICS and SCADA networks. The growing convergence of IT and OT infrastructures, along with rising adoption of remote monitoring and industrial IoT technologies, is expanding identity-related attack surfaces. IAM solutions help organizations enforce role-based access control, multi-factor authentication, and privileged access management to reduce insider threats, prevent unauthorized command execution, and strengthen cybersecurity across connected industrial operations.
"By deployment mode, the on-premises segment is estimated to lead the market in 2026."
The on-premises segment is estimated to lead the OT security market in 2026 due to the critical need for direct control, low-latency monitoring, and data sovereignty across industrial environments. Industries such as energy, manufacturing, utilities, and oil & gas continue to rely heavily on on-premises OT security deployments to protect sensitive operational data and maintain uninterrupted control over ICS and SCADA systems. Many industrial operators prefer localized security architectures due to regulatory compliance requirements, legacy infrastructure dependencies, and concerns related to cloud connectivity within mission-critical operations. Additionally, on-premises deployments enable faster incident response, tighter network segmentation, and continuous monitoring of industrial assets without exposing operational environments to external network risks, making them a preferred deployment model across critical infrastructure sectors.
"By organization size, the SMEs segment is expected to exhibit a higher CAGR than the large enterprises segment during the forecast period."
The SMEs segment is expected to witness rapid growth in the OT security market due to increasing digital transformation initiatives and rising cybersecurity risks across small and mid-sized industrial enterprises. SMEs in manufacturing, utilities, and industrial operations are increasingly adopting connected production systems, industrial IoT devices, and remote operational technologies, expanding their exposure to cyber threats targeting OT environments. At the same time, limited in-house cybersecurity expertise and reliance on legacy industrial systems are driving demand for cost-effective and scalable OT security solutions. SMEs are increasingly investing in industrial network monitoring, secure remote access, asset visibility, and threat detection technologies to minimize operational disruption, improve resilience, and protect critical industrial processes from ransomware and unauthorized access attacks.
