South Staffordshire Water — ICO £963,900 fine

ICO fines South Staffordshire Water £963,900 over the 2022 Cl0p ZeroLogon kill-chain intrusion (daily 2026-05-12). The water-sector OES finding with the partial SIEM coverage detail (5% host-inventory coverage) is the operational lesson for any utility / critical-infrastructure operator with patchy telemetry. Regulatory significance: the ICO penalty on a critical-infrastructure operator gives Swiss BACS / EU NIS2 competent authorities a template fine-calculation for analogous deficiencies (daily 2026-05-12).
