THE UK'S NEW CYBER SECURITY & RESILIENCE BILL

POSTED: APR 24, 2025 // LEGISLATION ALERT // TAGS: COMPLIANCE

READ TIME: 3 MIN // IMPORTANT UPDATE

Recognising the escalating risk of digital threats, the UK government has introduced the Cyber Security and Resilience Bill (April 2025). This isn't just another minor update; it's a fundamental shift in how the UK approaches cyber resilience, expanding upon the 2018 NIS Regulations.

Key Updates in the Bill

1. Managed Service Providers (MSPs) Are Now In Scope

Previously, many MSPs operated outside direct cyber regulation. Now, providers offering ongoing IT management or support fall under the regulatory umbrella. They face robust security measures and incident reporting duties.

2. Sharper Focus on Supply Chain Security

The Bill empowers regulators to designate specific high-impact suppliers as 'Designated Critical Suppliers' (DCS). Businesses already regulated will face stricter requirements to manage cyber risks within their own supply chains.

3. Faster, Broader Incident Reporting

A strict two-stage timeline applies: an initial notification to the regulator within 24 hours of awareness, followed by a detailed report within 72 hours.

The Impact on Business
