Advanced Security Programs
Operational Technology Testing
Uncover hidden threats across operational technology (OT) environments to validate security, safety, and resilience against real-world adversaries.
OT Security Assurance
Operational Technology (OT) environments power critical processes across manufacturing, energy, utilities, transportation, healthcare, and critical infrastructure. These environments integrate industrial control systems, field devices, legacy platforms, modern networks, and human operators, often with limited tolerance for disruption.
Adversaries target OT environments by exploiting the interaction between industrial systems, enterprise networks, remote access pathways, hardware devices, and human workflows. OnDefend OT security testing combines elite adversary expertise with proprietary technology to assess OT environments as integrated operational ecosystems.

OT Security Testing Capabilities
Adversary-Driven OT Testing
We simulate real-world adversaries targeting OT environments to understand how attackers gain access, interact with industrial systems, and create operational risk while prioritizing safety and system stability.
Industrial Network and Segmentation Testing
We assess OT network architectures to identify segmentation weaknesses, insecure trust relationships, and exposure between IT and OT systems that could allow unauthorized access or operational disruption.
Control System and Protocol Assessment
We evaluate industrial control systems and protocols to identify insecure configurations, weak authentication, and exposure that could enable manipulation, interruption, or degradation of operations.
Hardware, Firmware, and Embedded Device Testing
We assess PLCs, RTUs, controllers, sensors, and other embedded OT devices to identify firmware weaknesses, insecure interfaces, and unauthorized communications.
Remote Access and Vendor Connectivity Testing
We evaluate remote access pathways, vendor connections, and maintenance interfaces to identify exposure that could enable unauthorized access into OT environments.
Human and Operational Workflow Testing
We assess how human processes, procedures, and operational workflows can be exploited to bypass technical controls or delay detection and response.
Risks Uncovered
OnDefend OT security testing identifies real-world risks adversaries can exploit to impact safety, availability, and operational integrity, including:
OT and IT Boundary Exposure
OT and IT Boundary Exposure
Risk introduced by weak segmentation or trust relationships between enterprise IT systems and OT environments.
Insecure Control System Configurations
Insecure Control System Configurations
Misconfigurations in control systems, protocols, and devices that enable unauthorized access or manipulation.
Hardware, Firmware, and Embedded Device Risk
Hardware, Firmware, and Embedded Device Risk
Insecure OT hardware and firmware that introduce hidden exposure or persistence within industrial environments.
Remote Access and Vendor Connectivity Risk
Remote Access and Vendor Connectivity Risk
Exposure introduced by third-party access, maintenance interfaces, and remote connectivity pathways.
Detection and Monitoring Gaps
Detection and Monitoring Gaps
Limited visibility into OT environments that delays identification of adversary activity or abnormal behavior.
Response and Recovery Weaknesses
Response and Recovery Weaknesses
Gaps in incident response coordination and recovery procedures that increase operational impact.
Human and Procedural Risk
Human and Procedural Risk
Operational practices and workflows that can be exploited to bypass controls or delay containment.
Operational Safety and Resilience Risk
Operational Safety and Resilience Risk
Conditions that could allow adversary activity to degrade safety systems, availability, or process integrity.

What is OT security testing?
OT security testing evaluates the security of industrial control systems and operational environments, focusing on how adversaries could impact safety, availability, and operational integrity.
How is OT testing different from IT penetration testing?
OT testing prioritizes safety and system stability while assessing industrial protocols, devices, and workflows that differ significantly from traditional IT systems.
Can OT security testing disrupt operations?
Testing is carefully scoped and coordinated to minimize risk and avoid operational disruption.
Which industries benefit from OT security testing?
Energy, utilities, manufacturing, healthcare, transportation, oil and gas, and critical infrastructure organizations benefit most.
Does OT testing include hardware and firmware?
Yes. Testing can include PLCs, controllers, sensors, firmware, and embedded devices used in industrial environments.
Does OT security testing support compliance?
Testing supports governance and regulatory efforts by validating real-world security effectiveness beyond checklist compliance.
