Investigation expertise built for OT
When an OT security incident happens, everything moves fast. You need to understand what occurred, how it happened, and what comes next. Most internal teams don't have the OT-specific expertise this requires. Fast breach identification reduces operational impact and recovery time. Real threats need to be distinguished from normal anomalies so your team can act with confidence instead of guessing.
Investigation services bridge that gap. Specialized OT expertise strengthens existing teams when it matters most. Pre-planned responses mean starting from readiness, not panic. Clear answers enable faster, stronger recovery.

OT Security Investigation FAQs
What is OT Incident Response?
OT Incident Response is the process of identifying, containing, investigating and recovering from cyber incidents affecting Operational Technology environments. It takes account of the safety, availability and operational requirements of industrial systems, where traditional IT response actions may create additional risk or disruption.
What is an OT security investigation?
An OT security investigation examines suspected or confirmed malicious activity within an industrial environment to determine what happened, which systems were affected and whether attacker access remains active. It can include analysis of network activity, endpoints, identities, logs and other available forensic evidence.
What happens during an OT cyber incident investigation?
An investigation typically begins with triage and scoping to understand the affected environment and immediate operational risks. Specialists then analyze available security and forensic data, identify malicious activity, assess the extent of compromise and support appropriate containment, remediation and recovery actions.
Can OT systems be investigated without shutting them down?
In many cases, yes. OT investigations should be planned around the operational and safety requirements of the environment, and it may be possible to collect and analyze evidence without taking critical systems offline. Where isolation or shutdown is required, the decision should be coordinated with operational and engineering stakeholders.
What should we do if ransomware affects an OT environment?
Ransomware affecting OT should be treated as a serious cyber incident. Organizations should escalate the incident immediately, assess whether operational systems are affected, preserve relevant evidence and seek specialist OT Incident Response support. Containment decisions should consider both cybersecurity risk and the potential impact on safety and operations.
Can an attacker move from IT into OT systems?
Yes. Weak segmentation, compromised credentials, remote access services and shared infrastructure can create routes between enterprise IT and OT environments. Investigations should therefore consider whether malicious activity originated in IT and whether attackers were able to move towards operational systems.
How can you tell whether an OT environment has been compromised?
Potential signs include unusual network communications, unexpected changes to system behaviour, suspicious remote access, unexplained authentication activity, malware alerts or unauthorized changes to devices or configurations. Because OT environments can generate complex normal traffic, specialist analysis may be required to distinguish malicious activity from legitimate operational behaviour.
Can Integrity360 investigate historic OT compromise?
Yes, where sufficient evidence remains available. Historical logs, endpoint data, network records and other forensic artifacts may help identify previous malicious activity. The ability to reconstruct older incidents depends on factors such as data retention, system logging and how much time has passed.
When should an OT Incident Response retainer be used?
An OT Incident Response retainer is designed to establish access to specialist support before an incident occurs. It can be valuable for organizations operating critical or complex industrial environments where rapid access to experienced OT responders is important and delays during an active cyber incident could increase operational risk.
Can OT Incident Response support regulatory or compliance requirements?
Yes. OT Incident Response can provide factual findings and documented evidence that may support internal governance, legal advisers, insurers, regulators and compliance activities. The investigation can help establish what happened, which systems were affected and what remediation actions have been taken.
