OT & ICS
Penetration Testing
Find security gaps in industrial and control systems. We agree the scope and testing windows with your operations team before starting.
Overview
Secure the systems that run the plant.
We assess IT/OT segmentation, remote access, and control-system security using passive and carefully controlled active techniques aligned to IEC 62443 and NIST SP 800-82, with safety always the first priority.
Coverage
What we assess.
Control-system security without risking safety or uptime.
- IT/OT network segmentation
- PLC, SCADA & HMI security
- Industrial protocols (Modbus, DNP3, etc.)
- Remote access & VPN
- Asset discovery & inventory
- Passive vulnerability assessment
- Purdue model review
- Safety-system awareness
FAQ
OT & ICS penetration testing FAQ
Scope, cost, and what happens next.
How much does OT/ICS penetration testing cost?
It is scoped to the number of sites, control systems, and protocols involved. Contact us or use our estimator for a tailored figure.
Is it safe to test live industrial systems?
Yes — safety is the priority. We use passive techniques and carefully controlled active testing, and avoid anything that could disrupt operations or safety systems.
Which standards do you align to?
IEC 62443 and NIST SP 800-82, plus the Purdue reference model for segmentation.
Do you test segmentation between IT and OT?
Yes — validating the boundary between corporate IT and the OT environment is one of the highest-value parts of the assessment.
Can you test without touching production?
Often, yes — through passive monitoring, configuration review, and testing in maintenance windows or on non-production segments.
Which industries is this for?
Energy and utilities, manufacturing, transport, water, and any organisation running industrial control or building-management systems.
More questions about this service
Do you cover building management systems (BMS)?
Yes — BMS and other cyber-physical systems can be included in scope.
What do we receive?
A risk-rated report with findings, segmentation analysis, and a prioritised, safety-aware remediation roadmap.
