Prepare for the UK Cyber Security and Resilience Bill

The document summarizes the UK Cyber Security and Resilience Bill (CS&R), expected to take effect in 2026, which broadens the NIS regime to cover OES, RDSPs (including MSPs), large data centres, and designated critical suppliers, aligning the UK with EU NIS2. It emphasizes baseline security standards (MFA, encryption, segmentation, patching), stronger supply-chain security and contractual obligations, and accelerated incident reporting (notify within 24 hours, full report in 72), while expanding regulator powers and transparency. Backed by NCSC’s CAF and Cyber Essentials, the paper provides a practical checklist: determine scope and regulator, perform gap and supply-chain analyses, update incident response for 24/72-hour timelines, document evidence, and conduct regular testing, noting that secondary legislation will refine sector-specific requirements.
