What’s New in NIST CSF 2.0?

The National Institute of Standards and Technology (NIST) has officially released version 2.0 of its landmark Cybersecurity Framework (CSF), marking its first major update since the framework’s inception in 2014. The revised framework introduces significant enhancements designed to extend its applicability and effectiveness across a broader spectrum of organizations, ranging from the smallest schools and nonprofits to the largest corporations and government agencies. Here’s what you need to know about the changes in NIST CSF 2.0.

From the NIST CSF 2.0: CSF Functions

Expanded Scope and Audience

Originally focused on critical infrastructure, NIST CSF 2.0 broadens its target audience to include organizations of all sizes and sectors. This inclusive approach aims to assist any entity in managing and mitigating cybersecurity risks, regardless of its cybersecurity expertise level. The update signifies NIST’s commitment to making cybersecurity accessible and manageable for all organizations.

Enhanced Core Guidance and Resources

In response to feedback on the draft version, NIST has enriched the CSF’s core guidance and introduced a suite of resources to facilitate the framework’s adoption and implementation. These resources offer tailored entry points into the CSF, making it easier for different types of organizations to apply the framework effectively in their operations.

Focus on Governance and Supply Chains

A notable addition to CSF 2.0 is its emphasis on governance and supply chain risks. The framework now includes guidance on how organizations can make informed decisions regarding cybersecurity strategy and how to integrate these considerations into their overall enterprise risk management. This shift underscores the importance of viewing cybersecurity as a critical component of organizational health and sustainability.

Introduction of the “Govern” Function

CSF 2.0 introduces a new key function, “Govern,” expanding the framework’s core from five to six functions. This addition aligns with the framework’s increased focus on governance, providing a structured approach to managing cybersecurity risk as an integral part of organizational governance.

Implementation Tools and Reference Catalog

To support organizations in adopting CSF 2.0, NIST has launched new tools, including a CSF 2.0 Reference Tool and a searchable catalog of informative references. These resources simplify the process of implementing the CSF, allowing organizations to map their current cybersecurity actions to the framework and access a comprehensive catalog of cybersecurity documents for reference.

Continuous Improvement and Community Engagement

NIST emphasizes the importance of community feedback in the ongoing development of the CSF. Organizations are encouraged to share their implementation experiences and successes, contributing to the framework’s evolution and enhancing its utility for a wide range of users.

International Use and Alignment

The CSF enjoys wide international adoption, with previous versions translated into 13 languages. NIST anticipates that CSF 2.0 will also be translated by volunteers worldwide, further extending its global reach. Additionally, NIST’s collaboration with the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) continues to foster international alignment of cybersecurity documents and frameworks.


NIST CSF 2.0 marks a pivotal update in the framework’s development, introducing comprehensive guidance, fresh resources, and an extended scope to tackle the cybersecurity challenges of the modern era. With a focus on inclusivity, governance, and offering actionable tools, NIST strives to encourage CSF adoption among a wide range of organizations, boosting their capabilities in managing cybersecurity risks efficiently. As the nature of cybersecurity threats transforms, the NIST CSF evolves in tandem, ensuring it remains relevant and effective in the face of a modern, dynamic digital environment. It is imperative that organizations embrace the future of cybersecurity management by integrating NIST CSF 2.0 into their security strategy.
