What is the NIST Cyber Security Framework?
What is the NIST Cyber Security Framework?
The NIST Cybersecurity Framework (CSF) is a voluntary framework developed by the US National Institute of Standards and Technology that provides organisations with a structured, risk-based approach to managing cybersecurity risk. Originally released in 2014 and significantly updated in February 2024 with CSF 2.0, it is now the most widely adopted cybersecurity framework globally — used by organisations across every sector and in over 50 countries.
CSF 2.0 introduces a sixth Core Function — GOVERN — reflecting the increasing importance of board-level cybersecurity governance. The framework is explicitly designed to be technology and sector-agnostic, scalable from small businesses to large enterprises, and complementary to other frameworks, including ISO 27001, CIS Controls, DORA, and NIS2.
Unlike certification-based frameworks, the CSF does not produce a pass/fail certificate. Instead, it provides a structured language for communicating cybersecurity risk, measuring maturity, and directing investment — making it as valuable for board reporting as it is for technical programme management.

Define the scope of the CSF engagement by clearly stating which business units, systems, and processes are involved. It’s also important to set an organisational context that includes the company’s mission, the regulations it follows, the acceptable risk levels, and the expectations of different stakeholders. This understanding will help ensure effective engagement and decision-making throughout the process.
Scoping
& Context
Popular Managed Services:
Evaluate the organization’s current cybersecurity practices by checking them against the six Functions of the Cybersecurity Framework (CSF) and their Categories. This evaluation should include a thorough review of documents, a technical analysis, and interviews with key stakeholders to create a clear and informative picture of the organization’s cybersecurity status.
Current State Assessment
Popular Managed Services:
Work closely with leadership and risk owners to define the organisation’s main Critical Success Factor (CSF) profile — which means setting the desired maturity level for each Category. This should be aligned with business goals, the organisation’s risk tolerance, and the available budget, ensuring a balanced approach that supports both strategic aims and risk management.
Target Profile
Definition
Popular Managed Services:
Create a clear and prioritized plan to bridge the gap between the current and target profiles. This plan should outline and prioritize actions based on their impact on reducing risks and the effort needed to implement them. It should allow for a phased approach over 12 to 36 months to ensure successful goal achievement.
Popular Managed Services:
Roadmap
Development
Provide expert advice and hands-on help to carry out roadmap initiatives while keeping all stakeholders informed and involved. Track progress against goals and regularly check in for alignment with organizational aims. Continuously update the roadmap to address potential threats and changing business needs, ensuring it remains relevant and supports our initiatives’ success.

NIST CSF Structure
Six distinct categories comprise the NIST Cybersecurity Framework (CSF) standard, and these categories provide various significant benefits for businesses seeking to enhance their cybersecurity posture and resilience against potential threats. By understanding and implementing these categories, organizations can develop a more robust security strategy, effectively mitigate risks, and improve their overall readiness to respond to evolving cyber threats in today’s rapidly changing digital landscape. This proactive approach ultimately contributes to a stronger defense and helps in maintaining trust with clients and stakeholders alike.
Categories
Establishes and monitors the organisation’s cybersecurity risk management strategy, expectations, and policy. Covers organisational context, risk management strategy, roles and responsibilities, policy, and oversight.
Categories
- Organisational Context (GV.OC).
- Risk Management Strategy (GV.RM).
- Roles, Responsibilities & Authorities (GV.RR).
- Policy (GV.PO).
- Oversight (GV.OV).
- Cybersecurity Supply Chain Risk Management (GV.SC).
Helps develop an organisational understanding of how to manage cybersecurity risk across systems, people, assets, data, and capabilities. Covers asset management, risk assessment, and improvement.
Categories

Key Points
- NIST CSF 2.0 is built around six core functions: GOVERN, IDENTIFY, PROTECT, DETECT, RESPOND, and RECOVER.
- The framework helps boards and leadership teams understand current cyber risk and target improvement priorities.
- Current and target profiles help organisations compare where they are today against where they need to be.
- The framework supports investment planning, regulatory readiness, evidence for cyber insurance, and supplier assurance.
- It maps well to ISO 27001, CIS Controls, DORA, NIS2, SOC 2, PCI DSS, and Cyber Essentials.
- Implementation tiers describe how deeply cybersecurity risk management is embedded into business operations.
- It provides a practical structure for assessing cybersecurity maturity without requiring formal certification.
- NIST CSF is suitable for organisations of all sizes because it is flexible, scalable, and risk-based.

Frequently Asked Questions
Find answers to your questions about our services and how we can assist you.
Does the NIST CSF produce a formal certification?
What is the difference between CSF 1.1 and CSF 2.0?
CSF 2.0 (released February 2024) introduced several significant changes from the previous version (CSF 1.1): a sixth Core Function — GOVERN — was added, reflecting the critical importance of board-level cybersecurity governance and organisational accountability. The framework was expanded beyond critical infrastructure to explicitly address all organisations of any size and sector. Supply chain risk management was elevated and given greater prominence. The community profiles concept was formalised, and the framework provides improved mappings to other standards. Organisations on existing CSF 1.1 programmes should plan to migrate to CSF 2.0.
How long does a NIST CSF assessment take?
A NIST CSF assessment typically takes 3–6 weeks from scoping to final report delivery — depending on the size and complexity of the organisation, the number of in-scope business units, and the depth of evidence review required. The assessment involves document review, structured interviews with technical and leadership stakeholders, and a maturity-scoring workshop to validate the findings. For larger or more complex organisations, phased assessments focusing on one or two functions at a time can reduce the initial burden.
Can NIST CSF help with DORA compliance?
Yes. The Digital Operational Resilience Act (DORA) for EU financial entities has significant structural alignment with the NIST CSF — both are risk-based frameworks covering risk governance, protection, detection, response, and recovery. NIST CSF 2.0’s GOVERN function aligns closely with DORA’s ICT risk management governance requirements. We provide a crosswalk analysis that maps your existing CSF programme to DORA obligations, identifying which controls satisfy both frameworks and where DORA-specific gaps remain — avoiding duplication of evidence and effort.
