Why NIST CSF
When a US customer, investor or board member asks how mature your security is, they often mean “against NIST”. The framework gives everyone a shared language, from engineers to directors, and the 2.0 update added a Govern function that puts leadership accountability front and centre.
The six functions
The CSF organises cybersecurity outcomes into six functions, broken down into categories and subcategories. Govern sits at the centre because it shapes how you carry out the other five.
- Govern
Set and oversee strategy, roles, policy and supply-chain risk. New in 2.0, and it informs the other five. - Identify
Understand your assets, suppliers and cyber risks. - Protect
Safeguards that manage those risks: access, training, data security, platform security. - Detect
Find and analyse possible attacks and compromises. - Respond
Act on a detected incident: manage, analyse, contain and report. - Recover
Restore assets and operations after an incident.
A good first step towards certification
A NIST CSF assessment is a practical way to see your whole security picture before committing to a certification. The outcomes map closely to ISO 27001 and SOC 2, so the work you do now is reused when you go for a certificate.
What's included
- Scoping workshop to agree what is in scope and why
- Current profile across Govern, Identify, Protect, Detect, Respond and Recover
- Target profile based on your risk, customers and budget
- Mapping to the ISO 27001 or SOC 2 controls you already operate
- Prioritised roadmap and a board-ready summary
When you'd use this
- US customers or investors ask you to describe your security against NIST
- Your board wants a clear, recognised view of cyber risk
- You want a structured starting point before choosing a certification
