Sector: Major European energy utilities operating power generation, transmission and distribution infrastructure.
Challenge: IT security teams managed enterprise controls but had no visibility on OT-specific risks. OT teams understood industrial processes but lacked compliance expertise. No common framework existed to evaluate the same software against both IT regulations and OT frameworks. Audit findings were fragmented across two silos with no shared reference.
Sector: Major European energy utilities operating power generation, transmission and distribution infrastructure, classified as operators of vital importance.
Context: The utilities operated under dual compliance pressure: enterprise IT policies governed by ISO 27001 and national regulations, and OT-specific requirements driven by defense regulations (LPM) and industrial standards.
Challenge: IT security teams managed enterprise controls but had no visibility on OT-specific risks such as safety system isolation, industrial protocol security and obsolescence in air-gapped environments.
Consequence: Two parallel audit trails with no shared reference. Findings fragmented, remediation plans contradicted each other, and the board received two different versions of the compliance posture.
Compliance takeaway: IT/OT governance harmonization fails without a shared compliance reference. Unified compliance maps covering IT regulations (NIS2) and OT frameworks (NIST SP 800-82, MITRE ATT&CK ICS) provide one source of truth instead of two separate audit trails.
