The NIST Cybersecurity Framework (NIST CSF) is a set of guidelines and best practices developed by the National Institute of Standards and Technology (NIST) to help organisations manage and reduce cybersecurity risk. The NIST CSF provides a flexible and cost-effective approach to improving cybersecurity posture and is applicable to organisations of all sizes and sectors.
The framework integrates NIST standards, including those from the NIST Special Publications 800 series (NIST SP 800). The NIST CSF 2.0 version is the latest revised version which has included new updates to remain relevant and effective.
NIST CSF 2.0 is the updated version of the original NIST Cybersecurity Framework. It builds upon the foundational principles of NIST CSF to address new and evolving cybersecurity challenges. The updated framework aims to provide enhanced guidance for managing cybersecurity risks, including improved alignment with international standards and practices.
Key updates:
The NIST CSF Core forms the foundation of the framework, organised into six Core Functions. The order of Functions does not imply a sequence or prioritisation. Instead, the CSF Functions should be seen as interconnected elements that need to be addressed simultaneously. The six Core Functions are:
When implementing the NIST CSF, consider incorporating the CSF Tiers and Organisational Profiles alongside the Core structure. Both components enhance the effectiveness of NIST CSF implementation by tailoring cybersecurity efforts to the organisation's needs.
CSF Tiers assess the maturity of cybersecurity practices, from Tier 1 (ad hoc) to Tier 4 (adaptive), helping gauge and improve security posture. Ranging from Tier 1 to Tier 4, each tier represents a different level of cybersecurity risk governance practices and risk management practices as shown below:
CSF Organisational Profiles align CSF Core outcomes with business objectives and risk appetite, helping organisations develop tailored cybersecurity strategies. The current profile evaluates the organisation's existing outcomes, while the target profile defines desired outcomes. By comparing both, organisations can identify gaps and plan for improvement.
The NIST CSF provides a structured approach for organisations to assess, prioritise, and address cybersecurity risks. It enables informed decision-making, supports compliance, and strengthens risk management processes, both internally and with third parties. By aligning with NIST standards, the CSF helps organisations ensure compliance and strengthen their cybersecurity risk management processes.
As a high-level framework, it can be supplemented by detailed resources like the NIST SP 800 series and NIST Interagency Reports for specific risks. Its flexibility allows adaptation to various organisational needs and integration with other risk management programs, such as ERM, IT, supply chain, and AI risk management.
Understanding the NIST Cybersecurity Framework is only the first step. Implementing it effectively—tailored to your organisation’s risk appetite, sectoral demands, and existing cyber maturity—requires both strategic foresight and technical depth. That’s where Ensign can help. Our Strategic Advisory Services team works closely with you to assess your current security posture, define clear target profiles, and design a pragmatic, actionable roadmap aligned with the latest NIST CSF 2.0 updates. From supply chain risk to AI risk management, we bring local and global insights to help you close the gap between ambition and execution.
