Your industrial and critical infrastructure systems are too important to leave unsecured. Operational Technology (OT) and Industrial Control Systems (ICS) power the backbone of critical infrastructure. From electricity grids and water treatment plants, to manufacturing, oil and gas, and transportation networks.

Increasingly, attackers are targeting OT networks with ransomware, sabotage, and data exfiltration.

OT networks are highly sensitive, often fragile, and run legacy devices. A single aggressive scan or misconfigured test can disrupt operations within minutes, potentially impacting safety, production, and revenue.

Our Operational Technology (OT) and Industrial Control Systems (ICS) Security Testing finds vulnerabilities safely. We provide actionable remediation, keeping your operations, personnel, and assets protected.

What you receive

Our Operational Technology (OT) and Industrial Control Systems (ICS) Security Testing will give you a clear understanding of how attackers could exploit your infrastructure, and how to prevent this from happening.

We create a comprehensive and actionable report, which includes:

A summary highlighting operational risk

Technical findings for each device and network segment

Safe, proof-of-concept demonstration of successful attacks

Remediation guidance based on operational impact

Recommendations for improving security for your IT and OT teams

What we assess

Our Operational Technology (OT) and Industrial Control Systems (ICS) Security Testing looks at the full operational technology stack. We’ll give you examples of any vulnerabilities we uncover. A real-world scenario is a single compromised account leading to an attacker taking full operational control – manipulating processes or halting production. We can see the importance of account hygiene, monitoring, and segregation of duties.

Industrial Network Architecture and Segmentation

We evaluate network design, firewalls, VLANs, and IT-OT boundaries. Vulnerabilities include flat networks allowing lateral movement from IT to OT, insecure VPNs and remote access points, firewall rules for critical systems, inadequate monitoring and alerting.

User and Privileged Account Management

Weak account management is a major risk in OT environments. Insecure accounts are common. Vulnerabilities include shared operator or service accounts, accounts with excessive privileges, IT users with inappropriate OT access, defunct accounts, weak passwords or missing MFA, poor separation of duties between IT, OT, and operational staff, remote vendor accounts with unnecessary access.

Control Network and SCADA Systems

We assess network segmentation, protocol security, and device communications. Vulnerabilities include exposed SCADA services on the network, weak credentials on PLCs and HMIs, insecure protocol traffic and remote access to control systems.

Programmable Logic Controllers (PLCs) and Embedded Devices

We examine firmware, protocols, and physical interfaces for potential compromise points. Vulnerabilities include insecure passwords, firmware vulnerabilities, insecure serial or network interfaces.

Human-Machine Interfaces (HMIs)

We test authentication, session management, and backend interactions. Vulnerabilities include weak HMI authentication, misconfigured access to control functions, potential for operator command spoofing.

Data and Process Integrity

We assess how critical operational data is protected and whether process integrity can be maintained under attack scenarios. Vulnerabilities include manipulation of sensor data, unauthorised changes to PLC or HMI logic, unsecured historian databases, inadequate logging and audit trails.
