What Is an OT Security Investigation?
An OT security investigation examines suspected or confirmed malicious activity within an Operational Technology environment to determine what happened, which systems were affected and whether a threat remains active.
Unlike a traditional IT investigation, OT Incident Response must take account of operational availability, safety, specialist industrial protocols and the potential impact that containment actions could have on physical processes.
Integrity360 combines OT cybersecurity expertise with Incident Response and Digital Forensics to help organisations investigate threats while minimising unnecessary disruption to critical operations.
Challenges this service addresses
Limited OT Incident Response Expertise
Internal security teams may have extensive IT experience but lack the specialist knowledge required to investigate industrial systems safely.
Slow Detection and Containment
Attackers can remain undetected within industrial environments, increasing the risk of operational disruption and wider compromise.
Unclear Signs of Compromise
Normal OT behaviour can be difficult to distinguish from malicious activity, particularly where monitoring and logging are limited.
Lack of Prepared Response Arrangements
Without predefined escalation routes, specialist support or an Incident Response retainer, organisations can lose valuable time during a cyber incident.
Our investigation services
OT Incident Response Support
24/7 access to OT cybersecurity specialists who can help assess, contain and investigate cyber incidents affecting industrial environments, while considering operational safety and availability throughout the response.
OT Forensics
Analyse available OT, endpoint, network and security evidence to determine whether compromise has occurred, reconstruct attacker activity and establish the scope and impact of an incident.
Incident Response Retainers
Put response arrangements in place before an incident occurs, giving your organisation predefined escalation routes and rapid access to specialist OT Incident Response expertise when it is needed.

Why Choose Integrity360 for OT Incident Response?
-
Specialist Industrial Security Expertise
Experience supporting OT and industrial control environments across sectors including energy, manufacturing, public sector and maritime.
-
Combined IT and OT Investigation
Many industrial attacks begin in enterprise IT before moving towards operational systems. Integrity360 can investigate activity across both environments rather than treating them in isolation.
-
Certified Professionals
Our team brings global best practices, including IEC 62443, ISO 27001, , NIST SP800-82, and more.
-
Proven Track Record
Trusted by leading organisations across Europe and beyond to safeguard their critical operations.
-
Tailored Approach
No two OT environments are alike — our services adapt to your technologies, risks, and priorities.
-
Standards-Led Approach
Our specialists draw on recognised industrial cybersecurity practices, including IEC 62443 and NIST SP 800-82, where relevant.
Gartner Recognised
We are thrilled to share that Integrity360 has been recognised as a Gartner Representative Vendor in 5 of their Market Guides, including: Managed Security Services, Managed Detection and Response, Gartner's Market Guide for Co-Managed Security Monitoring Services and Managed SIEM Services.
Gartner has included a range of providers within its market guide for managed services to ensure clear coverage from a geographical, vertical and capabilities perspective. Those included in the Gartner market guide display clarity in the vision for an end-user outcome-focused offering distinct from a pure technology-driven offering.

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 analyse 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 analyse 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. Organisations 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 unauthorised 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 artefacts 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 organisations 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.
