OT AND ICS SECURITY
Operational technology (OT), industrial control systems (ICS), and IoT environments present unique security challenges — safety-critical systems, legacy platforms, and air-gap assumptions that no longer hold. CyberHeals delivers OT/ICS assessments using specialists who understand process environments and deliver findings without disrupting operations.
FULL OT/ICS COVERAGE
Assess, Segment, Monitor, and Protect
OT/ICS security assessment and vulnerability analysis
Network segmentation between OT and IT environments
Continuous OT monitoring and anomaly detection programs
OT and ICS environments prioritize availability and safety over confidentiality — a control system that is patched offline costs production time, and a scan that triggers a PLC response can cause a safety incident. OT security requires specialists who understand process control environments, use passive techniques, and deliver findings without disrupting operations.
An OT/ICS assessment discovers assets passively, maps network topology and OT/IT connectivity, identifies vulnerable devices, reviews access controls and remote access channels, and assesses segmentation between production zones. Findings are prioritized by operational risk and a remediation roadmap is developed around your maintenance windows.
We use passive network monitoring and asset discovery tools that capture traffic without generating queries or probe packets. Where active scanning is needed, it is coordinated during planned maintenance windows. We never run active scans against controllers, PLCs, or safety instrumented systems without explicit authorization and a prior safety review.
OT/IT convergence has eroded the air-gap assumptions that older OT architectures relied on. We assess your current network topology and design a segmentation architecture that isolates production zones, controls data historian access, and implements a DMZ between OT and enterprise networks — following the Purdue Model and IEC 62443 zone design principles.
Yes. IoT security covers device inventory and classification, vulnerability assessment for connected devices, firmware security review for critical devices, network segmentation to isolate IoT from enterprise systems, and monitoring for anomalous IoT device behavior. We cover industrial IoT, building management systems, and enterprise IoT device fleets.
OT security engagements are scoped based on the number of sites, operational zones, and protocols in scope. We provide a fixed-price proposal after a discovery call covering your operational environment, technology stack, regulatory requirements, and assessment constraints. Ongoing OT monitoring and program management retainers are available after initial assessment.
