The UK Cyber Security And Resilience Bill: How To Prep Your Business Now

On April 1st, 2025, the UK Government released a policy statement that could redefine cyber risk management for thousands of organisations. The upcoming Cyber Security and Resilience Bill marks a generational shift in how cyber regulations will be enforced—and who they will apply to.

This isn’t just a rebrand of NIS. This is a reboot of national cyber defence strategy, with sweeping implications for CISOs, CTOs, MSPs, and critical suppliers operating in or with the UK.

If your organisation handles sensitive data, supports essential digital services, or provides infrastructure to regulated industries, this bill affects you.



A Quick Recap: What’s in the Cyber Security and Resilience Bill?

The new legislation proposes to:

  • Expand the scope of existing regulations to include more digital service providers and supply chains.

  • Introduce mandatory cyber incident reporting within 24 hours, with detailed follow-up in 72.

  • Establish the NCSC’s Cyber Assessment Framework (CAF) as the new governance and control maturity baseline.

  • Strengthen regulatory oversight and enforcement powers.

  • Align closely with the EU’s NIS2 Directive, ensuring cross-border regulatory consistency.


The government’s message is crystal clear: resilience is no longer a best practice—it’s an obligation.


Why This Matters Now

If you're a Managed Service Provider, SaaS vendor, or digital supplier, the bill could bring you under direct scrutiny—even if you’ve previously operated outside the NIS regime.

The time to prepare is now, and the work ahead includes:

  • Understanding how your business maps to the updated scope

  • Performing a readiness assessment against CAF outcomes

  • Establishing or strengthening an ISMS aligned to ISO 27001

  • Preparing for real-time, continuous assurance models—not annual checkbox audits


Why ISO 27001 Is Still the Bedrock—But Needs a Reboot

Let’s be honest: ISO 27001 has long been considered the gold standard for Information Security Management Systems. But it was built for a different era, when compliance was slow, reactive, and document-driven.

In 2025, security teams don’t have the luxury of 12-month certification journeys, endless spreadsheets, or resource-hungry audits.

What you need instead is:

  • Continuous control visibility

  • Real-time risk monitoring

  • Automated evidence gathering

  • Alignment with CAF and NIS2 out-of-the-box

  • Executive-level reporting for boardroom defensibility
