Structure of the framework: Core, Profiles, Tiers
CSF 2.0 consists of three building blocks. The Core organises desired cybersecurity outcomes into six functions, 22 categories and 106 subcategories. Each subcategory describes an outcome, for example that roles and responsibilities for cyber risk are established and communicated. How you achieve this outcome is left open by the framework.
Profiles describe the state of an organisation along the Core. The current profile records what has been achieved today, the target profile what is to be achieved. The gap between them is your work programme. In addition, there are community profiles, which sectors or interest groups create as a shared baseline.
The tiers classify how rigorous and repeatable cyber risk management is governed overall. There are four: Partial, Risk Informed, Repeatable and Adaptive. They are explicitly not a maturity model for each individual subcategory, but describe the nature of governance.
In addition, NIST publishes implementation examples for the subcategories online, quick-start guides for smaller businesses and mappings to other frameworks, including NIST SP 800-53 and ISO 27001. These supplementary resources are updated continuously and available free of charge. In Sightadel, functions, categories and subcategories are set up as guided questions; the current profile is created as you answer.
Benefits for European companies
A framework from the US might at first seem out of place in Europe. In practice, many companies use it nonetheless, for three reasons. First, as a language for management: six functions are easier to understand than more than ninety controls from Annex A of ISO 27001. A supervisory board can do more with the sentence “Detect is at tier two, the target is three” than with a list of open controls.
Second, as an answer to questions from outside. Cyber insurers, international corporate customers and US partners often use the CSF to structure their questionnaires. If you have a well-maintained profile, you answer them faster and more consistently.
Third, as an umbrella for several frameworks. If you work with NIS2, ISO 27001 and customer requirements at the same time, you can bundle the measures under the six functions and report an overall status. The CSF alone does not fulfil legal obligations. It replaces neither NIS2 nor DORA nor a certificate. Its value lies in governance and communication.
For small organisations, the CSF is a good starting point because it does not prescribe which documents must exist. If you start small, tackle Govern first and the categories that affect your own business most.
Costs and internal effort
The framework itself is free; there is no certification fee. The Sightadel licence for the NIST CSF is charged monthly per edition, with discounts for multiple frameworks and advance payment. You can find all prices and a calculator on our pricing page.
The internal effort depends mainly on how deep you go. A first current profile for a mid-sized organisation can be done in a few weeks if information security, IT operations and someone from management work together. It takes more effort if reliable evidence is required for every assessment, for example because an external auditor or an insurer is to confirm the profile.
An external review is voluntary. If you want one, the auditor invoices their work directly to you. It depends on the scope, the number of sites and whether only the profile or also the effectiveness of the measures is reviewed. For difficult individual questions, you can book consulting as a package in the app.
A current profile that holds up
The current profile is only worth as much as its honesty. In practice, people like to assess what is intended, not what is actually happening. A draft policy is not an implemented outcome; a test carried out once is not a repeatable process.
A simple rule has proven itself: every rating above “partially implemented” needs evidence. This can be a record, a report from a tool, a sample or a resolution. In Sightadel, you link the evidence directly to the subcategory and give it an expiry date. If it expires, the status on the dashboard drops until new evidence is available.
The reasoning is just as important. Anyone reassessing next year will want to know why a subcategory was considered largely implemented at the time. Sightadel records answers, comments and evidence with dates, so that comparisons over the years rest on the same basis.
You mark subcategories that do not apply to you as not applicable, with reasoning. That is legitimate, but should remain the exception. A profile in which a third of the items are hidden raises more questions for auditors and insurers than it answers.
Setting the target profile and priorities
The target profile is a business decision, not a technical one. It derives from your objectives, your risks, legal obligations and customer expectations. Not every subcategory has to be fully implemented, and not every organisation needs the Adaptive tier.
A practical approach: first determine the subcategories that are mandatory by law or contract. Then those that address the greatest risks to your most important processes. Only after that comes the rest. This produces a list that management can understand and back with a budget.
In Sightadel, gaps between current and target become action plans with an owner and a due date. The dashboard shows how far you have come per function. For boards, one page is often enough: status per function, the three most important gaps, progress since the last report.
Also record which gaps you deliberately do not close. A documented risk acceptance by management is a legitimate outcome. It shows auditors and insurers that the decision was made and did not simply get left behind. Do not forget to review it after a year.
Ongoing operation and reporting
The CSF is not a project with an end date. Threats, systems and business change, and the profile has to keep up. Most organisations carry out a full reassessment once a year and update in between as needed, for example after an incident, an acquisition or the introduction of an important platform.
For ongoing evidence, it helps to plan recurring activities as cycles: access reviews, training, restore tests, vulnerability scans, supplier assessments. Each run produces evidence with a date. If it is missing, Sightadel reminds you before the gap shows up in the report.
The Govern function requires management to oversee cyber risk. In practice, this means regular reports to management and the supervisory board, documented decisions on risk acceptance and budget, and a clear owner. The activity log in Sightadel shows who decided what and when. Through the Trust Center, you share your status with customers and partners without answering every questionnaire afresh.
If you want an external opinion, have the profile assessed at regular intervals by an independent auditor. The auditor gets their own access in Sightadel to answers, reasoning and evidence, can comment and does not have to request folders by email.
