Expected introduction to Parliament in 2025, the Cyber Security Resilience Bill represents significant evolution from the 2018 Network Information Systems framework.
Key expansion elements:
Expanded entity coverage: Regulations extend beyond critical infrastructure operators to include Managed Service Providers (MSPs), data centre operators, and entities providing critical services. Thousands of organisations newly falling under regulatory scope face compliance obligations previously affecting only large critical infrastructure organisations.
Rationale: Regulatory framework recognises dependency on digital services and third-party providers. Single MSP breach could cascade affecting hundreds customer organisations. Supply chain vulnerability represents systemic risk requiring enhanced protection.
Supply chain security mandates: Organisations must evaluate and manage cybersecurity risks from third-party providers and vendors. Supplier assessments required before engagement. Ongoing monitoring ensures continued compliance. Incident notification procedures enable rapid response if vendors experience breaches.
Enhanced incident reporting: Two-stage notification process replacing simpler requirements. Significant incidents require notification to authorities within 24 hours. Detailed comprehensive report follows within 72 hours providing regulators essential information enabling rapid response and threat intelligence sharing.
Technical security standards: Alignment with NCSC Cyber Assessment Framework ensures consistency across organisations. Specific security requirements include risk assessments, security measures proportional to identified risks, incident response capabilities, supply chain oversight.
Why 2025 bill matters:
Organisations currently exempt from NIS framework face sudden compliance obligations. MSPs previously operating without incident reporting requirements now require 24/7 notification capabilities. Data centre operators must implement enhanced monitoring and response procedures. Compliance investment now essential to avoid regulatory penalties and operational disruption.
NIS2 Directive came into effect October 2024 whilst many organisations remain adapting requirements. For UK businesses operating within EU, NIS2 compliance remains essential despite Brexit.
Core NIS2 Requirements:
Expanded sector coverage: Essential and important entities across critical sectors including energy, transport, banking, healthcare, digital infrastructure. Expanded scope affects substantially larger portion European economy than NIS Directive.
Security measures: Organisations must implement robust measures and effective collaboration against cyber threats. Specific requirements include risk management, network security, cryptography, access controls, incident response, business continuity.
Mandatory incident reporting: Organisations must notify competent authorities and coordinated bodies of significant incidents. Two-stage reporting: initial notification within 24 hours, detailed report within 72 hours. Reporting enables threat intelligence sharing and rapid coordinated response.
Supply chain assessments: Organisations must evaluate cybersecurity risks from suppliers and third parties. Supply chain security becomes critical compliance consideration. Vendor assessments required, ongoing monitoring essential, incident notification procedures mandatory.
Transitional periods: Member states given time transposing measures into national law. Many organisat ions lag transposing requirements creating inconsistent implementation timelines across European Union. Compliance deadlines continue tightening throughout 2025.
UK businesses impact: Organisations with EU operations must comply NIS2 despite UK regulatory separation. Dual compliance requirement (UK Resilience Bill + NIS2) creates complexity for international operations. Integrated approach addressing both frameworks simultaneously delivers efficiencies.

Which regulatory framework applies to our organisation?
Framework applicability depends on organisational characteristics (size, sector, operations, data processing scope). GDPR applies all organisations processing UK resident data. NIS2 applies essential and important entities. Cyber Essentials applies all organisations seeking certification. DORA applies financial institutions. Cyber Resilience Act applies product manufacturers. Most organisations comply multiple frameworks simultaneously.
What are realistic compliance implementation timelines?
Initial compliance typically requires 6-12 months for comprehensive framework implementation. Full maturity achieving continuous compliance requires 18-24 months. Timeline varies significantly based on current security posture, organisational size, complexity, available resources. Earlier starting enables smoother implementation.
How should organisations prioritise competing requirements?
Risk-based prioritisation addresses highest-impact requirements first. GDPR compliance required universally regardless sector. NIS2/Resilience Bill apply critical infrastructure. DORA urgent for financial institutions (January 2025 deadline). Cyber Essentials benefits widespread certification. Integrated approach addressing requirements simultaneously through single programme proves most efficient.
What are costs of compliance non-compliance?
GDPR penalties reach £17.5 million or 4% global turnover. NIS2 penalties equivalent or higher depending member state. DORA penalties significant for financial institutions. Beyond financial penalties, non-compliance creates reputational damage, customer trust loss, competitive disadvantage. Early proactive compliance investment proves far cheaper than penalty remediation.
How frequently must compliance be updated as regulations evolve?
Regulatory landscape continuously evolves. Compliance programmes require annual review ensuring currency. Regulatory changes often announced with transition periods enabling planned updates. Organisations should maintain compliance flexibility enabling rapid adaptation to emerging requirements.
