Understanding the Cyber Security and Resilience Bill
The Cyber Security and Resilience (CSR) Bill strengthens the UK’s cyber regulatory framework by reforming the NIS Regulations 2018. It introduces clearer obligations for organisations delivering critical services and places greater emphasis on resilience across increasingly complex supply chains.
As cyber risk extends beyond individual organisations, disruption can quickly cascade across sectors and communities. The CSR Bill reflects this reality, making resilience, governance and assurance key priorities for senior leaders.
Who the CSR Bill applies to
The CSR Bill is expected to apply to organisations across critical services and their supply chains, including operators of essential services, important entities, third-party suppliers and public sector bodies with oversight responsibilities.
If you are unsure how the CSR Bill applies to your organisation, CGI can help you clarify your role and obligations.
What organisations need to do now
Preparing for the Cyber Security and Resilience Bill goes beyond compliance. Organisations need to understand their exposure, assess cyber maturity and take practical steps to strengthen resilience over time.
Key activities include understanding regulatory scope, assessing maturity against recognised frameworks, managing supply chain risk, strengthening governance and preparing for incident response and ongoing compliance.
