Case study
Offshore platform vendor risk assessment
An anonymised example showing how IEC 62443-aligned thinking can support vendor package review, interface risk and project assurance evidence.
A new offshore platform project in a remote international operating environment required several vendor-supplied control, safety, telecoms, and monitoring systems to be integrated into the wider OT environment.
We defined the system boundary, mapped vendor interfaces, and structured the platform into IEC 62443 zones and conduits. Each vendor package was reviewed against the project cybersecurity requirements, with risks captured in a register and linked to design controls, configuration evidence, testing requirements, and operational procedures.
The client gained a clear view of cybersecurity risk across the full offshore OT environment, including vendor gaps, interface risks, and evidence needed for design review, FAT, SAT, commissioning, and handover.
