The UK's New Cyber Security & Resilience Bill: Is Your Cardiff Business Ready?

The digital world doesn't stand still, and neither do the threats within it. Cyber attacks are becoming more frequent, more sophisticated, and potentially more damaging to businesses of all sizes. Recognising this escalating risk, the UK government has introduced the Cyber Security and Resilience Bill (April 2025), a significant piece of legislation designed to overhaul the nation's cyber defences.  

This isn't just another minor update; it's a fundamental shift in how the UK approaches cyber resilience, building upon the 2018 Network and Information Systems (NIS) Regulations. For businesses across the UK, including here in Cardiff and throughout Wales, understanding these changes isn't just advisable – it's crucial for compliance and continuity.  

As a leading Managed Security Services Provider (MSSP) based in Cardiff, Wales, 313SEC is here to break down these changes, explain their implications, and provide actionable guidance to help businesses stay compliant and secure.

What's Actually Changing? Key Updates in the Bill

The Bill introduces several major changes aimed at strengthening the UK's digital backbone:

• Managed Service Providers (MSPs) Are Now In Scope: This is perhaps the biggest shift. Previously, many MSPs operated outside direct cyber regulation. Now, providers offering ongoing IT management, monitoring, or support with access to client systems fall under the regulatory umbrella. They face similar duties to digital service providers, including robust security measures and incident reporting, with the Information Commissioner's Office (ICO) overseeing compliance. Data centres are also being considered for inclusion.  

• Sharper Focus on Supply Chain Security: Cyber risk often flows through the supply chain. The Bill empowers regulators to designate specific high-impact suppliers as 'Designated Critical Suppliers' (DCS). These DCSs, regardless of size, will face direct security obligations if their failure could significantly disrupt essential services. Additionally, businesses already regulated (Operators of Essential Services and Relevant Digital Service Providers) will face stricter requirements to manage cyber risks within their own supply chains.  

• Faster, Broader Incident Reporting: The days of only reporting major breaches that cause immediate disruption are gone. The Bill mandates reporting incidents capable of significant impact, even if disruption hasn't occurred yet, including major data confidentiality or integrity breaches. Crucially, a strict two-stage timeline applies: an initial notification to the regulator and the National Cyber Security Centre (NCSC) within 24 hours of awareness, followed by a detailed report within 72 hours.

• Higher Security Standards (Enter the CAF): The NCSC's Cyber Assessment Framework (CAF) is being put on a "firmer footing". This outcome-focused framework  is becoming the benchmark for demonstrating adequate cyber resilience for regulated entities.  

The Bottom Line: Impact on Your Business & The New Fines

These changes create a ripple effect:

• Direct Obligations: If your business is an MSP or gets designated a DCS, you have new, legally binding security and reporting duties.  

• Indirect Pressure: Even if not directly regulated, if you use an MSP or supply goods/services to essential sectors, expect increased scrutiny. Your clients will likely pass down stricter security requirements, and your regulated MSPs may adjust costs to cover their own compliance investments. This impacts businesses across Wales relying on secure digital supply chains.  

• Hefty Fines: Non-compliance carries serious financial risk. While specific fines under the new Bill are still being finalised through secondary legislation, the existing NIS framework allowed for fines up to £17 million. Consultations have mentioned potential penalties for MSPs around £100,000 or even 10% of annual turnover. Regulators are being given stronger enforcement powers and mechanisms to recover their costs. The message is clear: cyber resilience is no longer optional.  

• Resource Demands: Meeting these higher standards requires investment in technology, processes, staff training, and potentially expert guidance.

How Can Your Business Prepare and Stay Compliant?

Navigating this new landscape requires a proactive approach. Here’s a brief guide:

• Know Your Status: First, determine if you fall directly into scope as an MSP or potential DCS. Map out your critical suppliers and understand if they are likely to be regulated.  

• Assess Third-Party Risk: Talk to your current MSP (like 313SEC!) about their readiness for the new rules. Review contracts and enhance due diligence for all critical suppliers.  

• Get Familiar with the NCSC CAF: Understand the CAF's objectives and principles. Consider a gap analysis to see where your business stands.  

• Review Incident Response: Update your incident response plan to meet the stringent 24/72 hour reporting deadlines and the broader definition of reportable incidents. Regular testing is key.  

• Invest and Train: Allocate budget for necessary security upgrades and ensure your staff understand their role in maintaining security and reporting potential incidents.
