UK Cyber Security and Resilience Bill Targets MSPs, DCs

The UK Cyber Security and Resilience Bill introduces major obligations for critical infrastructure providers, MSPs, and large data centers. The legislation mandates 24-hour initial incident reporting, 72-hour full notification, supply-chain security controls, and fines up to 10% of global revenue for non-compliance. The requirements align with detecting threats using techniques like T1190 (Exploit Public-Facing Application), T1133 (External Remote Services), and T1486 (Data Encrypted for Impact). Data centers above 1 MW capacity will become regulated essential services, similar to water and electricity providers. MSPs must demonstrate improved monitoring, risk management, and incident response maturity. The bill aims to counter a surge in disruptive cyber incidents, including attacks that halted operations at Jaguar Land Rover. The legislation carries significant operational and financial impact: organizations must upgrade logging, monitoring, vendor risk programs, and governance. Boards must treat cyber risk as a regulated compliance obligation. Organizations should begin gap assessments, update IR playbooks for 24-hour reporting, harden supply-chain controls, and prepare to provide evidence of cybersecurity maturity under NIST or ISO frameworks.
