The COO’s Guide to the Cyber Security and Resilience Bill for Financial Services

New UK legislation is about to turn cyber resilience from guidance into enforceable law. While financial services firms remain regulated by the Financial Conduct Authority and Prudential Regulation Authority, the Cyber Security and Resilience Bill will impose strict obligations on the suppliers you depend on — from MSPs to data centres. For COOs, this is a critical moment to strengthen supply-chain oversight, incident readiness, and executive accountability before the rules take effect in 2026.

From guidance to legislation: why financial services COOs need to act now

In 2023–25, the UK Department for Science, Innovation and Technology (DSIT) published voluntary codes of practice around cyber governance and software security. Many firms treated these as best-practice guidelines, but now the government is turning those principles into binding law. 

The Cyber Security and Resilience Bill is the legislative step that follows those codes. It introduces formal compliance requirements, sector-specific enforcement powers, and major financial penalties. It’s expected to pass into law by Spring 2026. 

This update explains what’s changing, how the bill affects financial services companies, and provides practical implementation steps COOs should take to protect operations and ensure regulatory readiness. 

What Is the Cyber Security and Resilience Bill?

The Bill modernises and strengthens the UK’s Network and Information Systems (NIS) Regulations to address the growing threat of cyberattacks. It brings more sectors into scope and gives regulators greater powers to enforce mandatory security requirements.

What it means in practice: 

  • Legal obligations for cyber resilience: Firms must demonstrate they meet minimum cybersecurity standards aligned with the NCSC’s Cyber Assessment Framework (CAF). 
  • Expanded regulatory scope: The Bill brings more organisations and suppliers into scope, including MSPs, data centres, and critical vendors. 
  • Mandatory incident reporting: Notify your regulator within 24 hours of a significant incident; submit a detailed report within 72 hours. 
  • Stronger enforcement for new sectors: The Bill brings previously unregulated industries (such as MSPs, data centres, and digital service providers) under direct oversight. Regulators like the ICO and Ofcom now have the authority to audit, issue directives, and impose fines of up to £17M. 
  • Government intervention powers: In cases of national impact, authorities can issue binding instructions to affected firms. 

 

Status: Primary legislation, expected to become law by Spring 2026 

WEBINAR: Understand the DSIT Cyber Codes of Practice

Predecessors to the UK Cyber Security and Resilience Bill, three cyber experts share how actions you can take today to comply.

Who's Affected (and how it ties back to your organization)

Financial services firms are not directly regulated under the Bill, as you’re already covered under existing FCA/PRA resilience rules. This is ultimately a good outcome. Your regulatory burden doesn’t increase, but your suppliers now face higher security obligations. That means less risk across your supply chain, with no additional overhead for you.  

  • Third-party providers: MSPs and cloud vendors you depend on are now directly regulated, but you’re still accountable for their failures under FCA/PRA expectations. 
  • Data centres: If your services are hosted in large-scale facilities, typically those with over 1 megawatt (MW) of power capacity, those providers are now regulated.  
  • Designated critical suppliers: The government can now classify vendors in your supply chain as “critical,” meaning your procurement and risk management processes need to adapt fast.

A quick reference tool to view the key areas covered by the DSIT Software Security & Cyber Governance Codes of Practice, and how to operationalize for alignment today.

How COOs Can Limit Risk Now

1. Audit Your Supply Chain

Larger MSPs and hosting providers must now prove compliance, but smaller ones are out of scope of the new regulations – you may want to review those smaller suppliers to ensure they are managing risk appropriately. 

  • Action: Request evidence of mature CyberSecurity management – e.g. CAF alignment or ISO27001 certifications
  • Update contracts to include incident reporting SLAs 
2. Update Incident Response Plans

In-scope companies will have: 

  • 24 hours to notify regulators of a significant breach 
  • 72 hours to submit a full impact and mitigation report 
  • Action: Run tabletop exercises to validate internal coordination and response timelines 

This sets incident response expectations from the UK Government and aligns closely with existing data protection regulations.  Even if not your organisation is not in-scope of the Resilience Bill, this is the likely expectation in the future.

3. Plan for Government Oversight

In a national-level incident, the government may intervene directly. 

  • Action: Ensure your crisis playbooks account for external control and communication paths 
4. Confirm Executive Ownership and Assurance

Cyber risk is no longer just a technical issue, regulators expect to see named executive accountability and formal oversight. 

  • Action: Ensure your firm has assigned board-level ownership of cyber risk. Confirm your CISO or risk lead is reporting quarterly to the board, and that regular audits (internal or external) are verifying control effectiveness. 

How FoxTech Cyber Can Help

FoxTech supports UK financial services firms in building real, regulator-ready resilience, whether you’re preparing for a compliance audit, coordinating with your CTO/CISO on technical readiness, or strengthening supplier oversight. 

Threat Detection and Breach Monitoring 

The CS&R Bill (building on the NIS framework) requires in-scope organisations to monitor for anomalous behaviour and potential data breaches in a timely manner. FoxTech’s SOC provides real-time visibility and alerts, enabling prompt detection of threats and anomalous activity across a wide range of technologies – not just your typical endpoint devices. 

Incident Response & Reporting 

The CS&R Bill requires that in-scope organisations not only report incidents quickly (24 hours for initial notice and 72 hours for a full impact reportbut also understand the scope, nature, and user impact of a breach. FoxTech’s incident responders use one year of retained telemetry to investigate and document exactly what happened, who was affected, and how your organisation responded — so you can meet your obligations with confidence and speed. 

Security Control Testing 

Regulators expect organisations to prove that their defences are effective. FoxTech can help you meet this standard with regular penetration testing, validation of remediation, and full audit trails — aligned to NCSC’s Cyber Assessment Framework (CAF) and DSIT guidance. 

Built-In Compliance, Not Bolt-On 

If FoxTech is your MSP, you already benefit from a CAF-aligned security posture, including real-time monitoring, documented response plans, and evidence-based reporting. We’re built to meet the standards the Bill is enforcing.
