Protecting Operational Technology From Real-World Threats

Your Industrial Control Systems (ICS) and Operational Technology (OT) form the backbone of your mission-critical operations — yet they remain highly vulnerable to nation-state actors, ransomware groups, and supply chain attacks. NSI Global’s ICS/OT Penetration Testing services identify exploitable weaknesses in your industrial networks without jeopardising uptime or operational continuity.

Our industrial control systems testing methodology is trusted by manufacturing, utilities, energy, and transportation operators. We safely evaluate SCADA security, device integrity, protocol usage, and segmentation to provide actionable insights on system resilience and regulatory alignment.

Whether you operate a smart factory, a logistics terminal, or a water treatment facility, our team adapts to your architecture for safe, relevant results.

For a more intelligence-driven approach, see our Adversary Emulation for ICS/OT environments.

Core Deliverables

OT-Specific Attack Simulation

Assess how adversaries could exploit PLCs, HMIs, SCADA systems, and field devices in your environment.

Safe & Structured ICS Security Testing

Combines passive and active techniques to validate defences without interfering with live production.

Segmentation & Network Flaw Discovery

Expose protocol weaknesses, flat networks, and exposed remote pathways.

Clear Action Plan

Receive prioritised recommendations based on asset criticality, process dependencies, and business risk.

Why ICS Testing Matters

  • Most OT environments lack visibility and are not covered by traditional cyber tools
  • Legacy equipment makes patching impractical — ICS penetration testing gives insight without breaking functionality
  • Supports compliance with IEC 62443, NIST 800-82, and critical infrastructure mandates.
  • Prevents downtime from ransomware, data-wiping malware, or targeted sabotage.
