ICS and OT Testing Built Around Safety

Critical infrastructure across the GCC is under increasing pressure from cyberattacks—whether by ransomware actors seeking financial gain or state-linked threat groups targeting national resilience. NSI Global delivers tailored ICS and OT penetration testing services for high-risk environments including oil and gas, utilities, smart cities, and logistics.

NSI Global assesses approved components, network paths, protocols, remote-access mechanisms and segmentation controls without assuming that active testing is appropriate for live systems. Depending on the environment, testing may use architecture review, passive discovery, a laboratory or staging environment, or carefully authorised active techniques with defined safety constraints and stop conditions.

From refinery control rooms to airport automation and desalination plants, these systems are critical—and increasingly vulnerable. Our specialists operate within your change control, safety, and compliance frameworks to test securely and responsibly.

What We Focus On

Protocol & Architecture Assessment

Evaluate industrial communication protocols such as Modbus, DNP3, OPC, and BACnet.

Risk-Centric Testing

Identify high-impact attack paths based on asset criticality, threat profile, and external exposure.

Layered Network Review

Assess segmentation between IT and OT environments to reveal crossover and lateral movement risks.

Safety-Constrained ICS and OT Testing

Passive, laboratory, staging or client-approved active techniques, chosen according to operational risk and safety requirements, with defined stop conditions — coordinated closely with plant operations.

What the Assessment Supports

Stay ahead of evolving threats to your critical operations

Findings mapped to IEC 62443, NIST SP 800-82 Revision 3, the UAE Information Assurance Regulation and other regional frameworks where included in scope

Prioritised remediation to reduce the risk of downtime and high-impact attacks

Demonstrate operational technology security maturity to boards, regulators, and investors

Regional Expertise, Global Methodology

NSI Global combines GCC-specific threat intelligence with internationally recognised best practices for ICS security testing. All testing is conducted under strict rules of engagement, with confidentiality, safety, and resilience at the core of every engagement.
