By solution, IAM segment to exhibit highest CAGR during forecast period.
The IAM segment is expected to record the highest CAGR in the Europe OT security market due to the increasing reliance on third-party vendors, system integrators, and remote engineering teams in industrial operations. European OT environments often involve frequent vendor-led maintenance, outsourced operations, and cross-site access, making identity-based control a crucial requirement for effective security. IAM enables time-bound, role-based access and centralized credential management for engineers and contractors accessing plants, substations, and distributed control systems. As remote maintenance and shared operational responsibility expand, IAM is becoming a core requirement for secure OT access across Europe.
By deployment mode, cloud segment to witness higher CAGR than on-premises segment during forecast period.
The cloud deployment segment is expected to register a higher CAGR in the Europe OT security market due to the need to manage distributed, multi-site industrial operations across countries. European operators are increasingly requiring centralized visibility and monitoring across plants, substations, and remote assets, which is challenging to achieve with isolated on-premises deployments. Cloud-based OT security platforms support cross-site asset visibility, remote diagnostics, and unified monitoring, making them suitable for geographically dispersed industrial environments across Europe.
By service, consulting & integration segment to account for largest market share in 2025.
The consulting & integration segment is expected to hold the largest market share in 2025 as European organizations continue to manage complex legacy OT environments characterized by multi-vendor architectures and proprietary systems. Industrial operators rely on specialized OT expertise to integrate security controls without disrupting safety or uptime. Consulting-led engagements remain critical for network segmentation, asset mapping, secure remote access implementation, and system hardening, particularly during OT modernization initiatives across energy, utilities, manufacturing, and transportation sectors.
