Cyber Resilience Bill: What It Means for UK Businesses

Cyber Resilience Bill: What It Means for UK Businesses

If you’re responsible for cybersecurity in a UK organisation, with or without an MSSP, the time to prepare is now.

You’re Already Under Pressure. The Bill Raises the Stakes.

The UK Government is introducing the Cyber Security and Resilience Bill, before the end of 2025, that signals a major shift in how organisations must manage, report and prove cyber resilience.

The April 2024 policy statement may not be at the top of your reading list, but its implications demand attention. This isn’t about ticking boxes. It’s about demonstrating real-time cyber resilience, from your systems to your supply chain, in the face of escalating cyber threats.

The Hard Truth: This Isn’t Just Another Compliance Exercise

The government isn’t mincing its words. In the April 2025 policy statement, it called for

decisive action to deliver effective and enduring change.”

Why now? Because UK organisations lose nearly £22 billion a year to cyberattacks. This Bill is a direct response, designed to raise accountability, improve transparency and ensure readiness across the economy.

What’s Changing?

The Cyber Resilience Bill significantly expands and strengthens the NIS Regulations 2018, going far beyond critical infrastructure. Here’s what to expect:

1. 1. Expanded Scope:
      If you’re a digital service provider, cloud provider, managed security service provider, or part of a critical infrastructure supply chain, you are now in scope and must demonstrate your resilience.
   2. MSSPs Now Regulated:
      Managed security service providers will fall under regulatory scope for the first time, required to demonstrate robust security practices.
   3. Mandatory 24-Hour Incident Reporting:
      You’ll need to report significant incidents (including ransomware) within 24 hours, followed by detailed investigative reports.
   4. Stronger Regulatory Powers:
      Authorities will be able to issue sector-wide directives and compel organisations to take action, even if they aren’t the direct target of an attack.
   5. CAF Becomes Law:
      The NCSC’s Cyber Assessment Framework (CAF) will shift from guidance to a legal requirement. You’ll need to align your security controls to its four outcomes:

• • • Mandatory security risk
    • Protecting systems
    • Detecting threats
    • Minimising the impact of cyber incidents

1. 6. Supply Chain Accountability:
      You’ll be expected to assess and manage the cyber posture of your key vendors, especially those with access to sensitive data or systems.

The Real Risks of Inaction

Penalties haven’t yet been confirmed, but based on comparable legislation, we can expect them to be significant. The broader risks include:

• • Increased Exposure to Targeted Attacks:
    Greater transparency can work both ways. As incident reporting and compliance disclosures become mandatory, attackers may use this intelligence to identify lagging sectors or organisations slow to respond. Those with visible compliance gaps or outdated defences could be deliberately targeted with ransomware, data theft, or other attacks. means attackers will identify slow responders or vulnerable sectors with known compliance gaps. 
  • Supply Chain Exclusion:
    Larger organisations will tighten their supplier security requirements to comply with the new regulations, but non-compliant SMEs risk being cut from valuable contracts.
  • Reputational Damage:
    The Bill’s increased transparency requirements mean cyber incidents will become matters of public record. Those unprepared organisations could face an impact on brand trust and brand confidence.
  • Operational Strain:
    Without adequate tooling and preparation, the stricter reporting and response requirements could strain resources and create compliance bottlenecks. Security teams will need established processes and tools to meet the accelerated 24-hour reporting window while simultaneously managing incident containment.

What This Means in Practice

This isn’t just about paperwork – it’s a real-world test of your team’s ability to respond, report, and recover quickly.

Whether you run security fully in-house, rely on an IT partner, or work with an MSSP, you need to prepare across these five areas:

1. 1. Real-Time Threat Detection:
      24/7 monitoring is no longer optional if you want to meet the Bill’s reporting timelines. If you can’t detect and triage incidents at any hour, you risk breaching reporting deadlines. If you don’t have this in place, now is the time to address this gap.
   2. Incident Response Readiness:
      Can you detect, contain, and report incidents within 24 hours? If not, now is the time to address that.
   3. Board and Auditor Confidence:
      You’ll need to justify risk decisions not just technically, but strategically, at boards and regulatory levels.
   4. Supply Chain Oversight:
      The Bill puts a spotlight on supply chain vulnerabilities. Begin mapping and assessing your most critical suppliers now, especially those involved in data processing or system access.
   5. CAF Implementation:
      Your programme should align to the four CAF’s legal outcomes. This will become the new baseline for compliance.

Whether You Have an MSSP or Not – Ask Yourself

Regardless of your current setup — fully internal, hybrid, or supported by an MSSP — now is the time to ask:

• Do we have 24/7 threat visibility across our environment?
• Can we detect, investigate, and report a breach within 24 hours?
• Are we aligned with the CAF outcomes?
• Are our suppliers regularly assessed for cyber risk?
• Has our incident response plan been tested and refined?

If the answer is “not yet” or “not sure,” you’re not alone. But the time to act is now — because regulators expect readiness, not intent.

The Time to Act is Now

 The Cyber Security and Resilience Bill isn’t just another regulatory hurdle; it’s a fundamental shift in how the UK approaches cyber risk. The government has made it clear that the threat landscape demands urgent action, and they’re implementing unprecedented regulatory measures to address these growing cyber challenges.

These regulatory changes present an opportunity to strengthen organisational resilience beyond mere compliance. A strategic approach to implementation will enhance operational continuity and help safeguard critical business functions against an increasingly sophisticated cyber risk environment.

Whether you’re ready or not, the clock is ticking. A strategic, proactive approach will do more than help you comply — it will strengthen your resilience in the face of today’s evolving threats.

Our SOC team can help you assess and develop an efficient implementation roadmap. Because when it comes to cyber resilience, waiting until the law passes will already be too late. Book a call with our team to discuss your readiness.
