The most widely adopted cybersecurity framework in the US. NIST CSF gives organisations a common language for assessing and improving security posture — flexible, risk-based, and recognised across public and private sectors.
The NIST Cybersecurity Framework, in its 2.0 revision, organises security activity into six functions: Govern, Identify, Protect, Detect, Respond, and Recover. It is a voluntary framework rather than a certification — you assess your maturity against it and use the result to drive improvement.
Its strength is flexibility: it scales from a startup to a federal agency and maps cleanly onto other standards, so work done for NIST CSF feeds directly into ISO 27001 or SOC 2.
Because there is no formal certifying body, organisations typically demonstrate alignment through an independent assessment and a documented maturity profile.
The de-facto reference for cybersecurity maturity across American industry.
Originally designed for sectors where resilience is non-negotiable.
Any organisation that wants a structured, defensible view of where its security stands.
Delivered through our specialist network. We assess your posture against all six functions, score your current and target maturity, and hand you a prioritised roadmap — which doubles as a head start on ISO 27001 or SOC 2.
We define the boundary of your programme — systems, locations, and teams in scope — and agree the timeline and responsibilities up front, so there are no surprises later.
A structured assessment of your current posture against every requirement, producing a prioritised remediation plan with realistic effort estimates.
We write the policies, procedures, and controls, and work alongside your engineering team on a weekly cadence to implement them — not a stack of templates left for you to figure out.
The management system runs and generates evidence. We drive the internal audit and management review so the programme is demonstrably working before any external scrutiny.
We prepare the evidence package and sit alongside you through assessment, answering the assessor's questions directly rather than leaving you to defend the work alone.
NIST CSF is the most common common language for cybersecurity in the United States. Federal agencies, their contractors, and many large US enterprises use it to describe and measure security, and they increasingly ask suppliers to show alignment with it. Because it is voluntary and flexible, it suits startups as well as large organisations.
What an assessment gives you. We assess your current practices against the six functions, Govern, Identify, Protect, Detect, Respond and Recover, and produce a current profile, a target profile and a prioritised roadmap. The result is a clear picture of where you stand and what to do first.
NIST CSF, SOC 2 and ISO 27001. The three map closely to each other. US customers often ask for SOC 2, international customers for ISO 27001, and public-sector or critical-infrastructure buyers for NIST alignment. We plan the work once and reuse the evidence. See our SOC 2 page and ISO 27001 page.
Remote-first delivery. ISONEX works remotely with clients across the GCC, UK, EU and US. We run the assessment with your team and document the profile and roadmap, with calls scheduled around your working hours. Book a free advisory session.
Not in the formal sense — there's no accredited certificate. Organisations demonstrate alignment through an independent assessment and a documented maturity profile, which is what we produce.
They overlap heavily. A NIST CSF assessment is an excellent foundation for ISO 27001, since most of the controls and evidence carry across. Many clients use CSF to get oriented, then certify to ISO 27001.
No. NIST CSF is a voluntary framework. It becomes a practical requirement when US customers, federal contracts or regulators expect you to show alignment with it.
Yes. It is free to use and is applied worldwide. UK, European and GCC companies use it to structure their security programmes and to answer US customers' security expectations.
They overlap significantly. Work done for one feeds the others, so many companies use NIST CSF to set the roadmap and then pursue SOC 2 or ISO 27001 for external proof.
Yes. ISONEX is a remote-first consultancy and we deliver NIST CSF assessments for clients in the US, the UK, Europe and the GCC. Everything is done online, scheduled around your working hours.
