OT Cyber Incident Response

Stop the Threat. Restore Production.

Is your industrial control system (ICS) prepared for a targeted cyber attack? Unlike IT systems, an operational technology (OT) incident doesn’t just mean data loss—it means physical downtime, safety hazards, and massive production losses.

We provide specialised, rapid OT Cyber Security Incident Response (IR) services designed to contain, eradicate, and recover industrial operations with minimal impact on production.

The OT Cybersecurity Crisis

Why Speed is Everything

When a threat hits your PLCs, SCADA systems, or DCS network, every second counts. You need responders who understand the delicate nature of industrial protocols (Modbus, Profinet, EtherNet/IP) and the criticality of deterministic control.

IT Incident Focus	OT Incident Focus	The Stakes
Data Confidentiality	Physical Integrity & Safety	Catastrophic Equipment Damage
Service Restoration (Minutes/Hours)	Production Restart (Seconds/Minutes)	Massive Financial Loss & Regulatory Fines
Standard Forensics	ICS-Specific Forensics (e.g., PLC logs)	Human Life and Environmental Risk

Our 3-Phase OT Incident Response Service

Our methodology is tailored to the unique demands of the industrial environment, focusing first on containment to safeguard physical assets and then on fast, validated recovery.

Rapid Containment & Triage

The goal: Stop the unauthorised activity before it spreads or causes physical damage.

Network Segmentation

Immediate isolation of affected zones (e.g., firewall policy enforcement) while maintaining critical safety functionality.

System Triage

Non-invasive collection of volatile data (e.g., running processes, network connections) from industrial endpoints (HMIs, Engineering Workstations).

PLC/RTU Status Check

Quick, safe verification of controller program integrity and running state.

ICS Forensics & Root Cause Analysis

We utilise specialised tools to investigate the “how” and “who” without interrupting essential production where possible.

OT Endpoint Analysis

Deep dive into industrial PCs, historian servers, and jump boxes for Indicators of Compromise (IoCs).

Protocol Analysis

Decrypting and analysing industrial network traffic (Modbus TCP, OPC UA, EtherNet/IP) to map threat actor movement.

PLC Program Change Detection

Identifying unauthorised or malicious changes to PLC logic or firmware—a unique and critical step in OT forensics.

Eradication & Validated Recovery

We utilize specialized tools to investigate the “how” and “who” without interrupting essential production where possible.

Secure Backup & Restoration

Restoring systems from known-good, verified backups and implementing strict change management protocols.

Configuration Hardening

Patching vulnerabilities, enforcing multi-factor authentication (MFA) on industrial remote access, and restricting administrative privileges.

Post-Incident Audit & Training

Detailed reporting on the attack vector and customised training to prevent recurrence (based on NIST CSF and IEC 62443 guidelines).
