UK Cyber Security and Resilience Bill Introduces New Regulations for OT Asset Owners
The UK is undergoing a significant overhaul of its cybersecurity regulations with the introduction of the Cyber Security and Resilience Bill (CSRB). This bill, introduced in November 2025, represents the most substantial change to UK cybersecurity regulations since the Network and Information Systems regulations in 2018. The CSRB expands regulatory scope to include almost all operational technology systems as 'national resilience' assets. It introduces mandatory incident reporting, stricter penalties, and enhanced enforcement mechanisms. The bill aims to strengthen national resilience and reshape how critical infrastructure operators manage cyber risk.
