Information security
Both help you organise your company's security, but in different ways. ISO/IEC 27001 is an international certification: you follow the standard and an accredited body issues a certificate that proves your security to the market. The NIST CSF is a free framework from the United States that organises defence into easy-to-grasp areas, with no certificate. In practice, many companies use the NIST CSF to build the programme and ISO 27001 to prove it works.
In short
Side by side
| What to compare | ISO/IEC 27001 | NIST CSF |
|---|---|---|
| What it is | An international information-security certification. | A free security framework, created by NIST in the United States. Not a certification. |
| Where it comes from | International (ISO/IEC), accepted worldwide. | The United States (NIST). Heavily used there and increasingly abroad. |
| How it is organised | A management system with 93 controls (2022 version), split into four themes. | Six easy-to-grasp areas: Govern, Identify, Protect, Detect, Respond and Recover. |
| Is there a certificate? | Yes, issued by an accredited body. | No. You measure your maturity on your own. |
| Cost to adopt | There is a cost for the audit and for keeping the certificate. | The material is free. You pay only for the work of applying it. |
| How you prove it | A public certificate anyone can check. | A snapshot of your maturity, useful inside, but with no badge to show outside. |
| Who it serves | Those who need to prove security to customers, tenders and partners. | Those who want to organise defence and speak one language across teams. |
| How long it lasts | 3 years, with follow-up visits every year. | It doesn't expire. You review it when you want. |
The NIST CSF pairs with ISO 27001: the framework's areas point to the standard's controls, so you can use both with no rework. The CSF 2.0 version, from 2024, added the Govern area, which fits straight into the management ISO 27001 requires.
It is the international information-security standard. You organise the company's security (rules, risk analysis, controls and continual improvement) and an accredited body issues the certificate. It is the proof the market recognises right away, at home and abroad.
It is a United States guide that splits security into six simple areas: govern, identify, protect, detect, respond and recover. It earns no certificate. It helps you see where your defence is weak, plan improvements and align teams with a common language. It is free and easy to start.
How they fit together
Both look at the same security care, just with different purposes. The NIST CSF is the map: it helps you see where defence is weak and where to improve, in language everyone understands. ISO 27001 is the proof: it turns that work into a management system that an outside body audits and certifies. That is why many companies start with the NIST CSF to organise, then move to ISO 27001 when they need to show the certificate to a customer or a tender.
Which is your case
You need to prove security to a customer or tender
Go with ISO 27001
It is the certificate the market asks for as proof. Without it, many doors won't even open.
You want to organise your defence inside first
Start with the NIST CSF
It is free and quick to start. It shows where your security is weak and becomes the base that shortens ISO 27001 later.
You want both: organise and certify
NIST CSF to build, ISO 27001 to prove
The most efficient path. You use the framework to plan and the standard to certify, with a single effort.
Numbers that matter

How DM11 helps
We use the NIST CSF to see where your defence is weak and build the programme, and prepare ISO 27001 so you earn the certificate, with a single control and proof effort.
Frequently asked
Answers anchored in ISO/IEC 27001:2022 and the NIST Cybersecurity Framework 2.0.
No. The NIST CSF helps you organise security and see where to improve, but it earns no certificate. When a customer, a tender or a partner asks for proof of security, ISO 27001 is what answers, since it earns a certificate issued by an outside body. The two work well together: one organises, the other proves.
