What are frameworks?
Frameworks set a proven frame that organisations can follow instead of reinventing the wheel. They define requirements, measures and ways of working, and they bundle the experience of many organisations into a traceable standard. Where a single tool solves only part of the problem, a framework describes how risk assessment, Controls, roles and evidence work together across the whole life cycle. That is exactly what separates a framework from a plain list of measures: it supplies the structure and the audit logic as well.
Well-known frameworks
- ISO 27001 – the internationally recognised, certifiable ISMS standard
- IT-Grundschutz – the German standard published by the BSI, a national framework rather than an EU requirement, and easy to combine with ISO 27001
- NIST Cybersecurity Framework – widely used internationally, organised more around functions (Identify, Protect, Detect, Respond, Recover)
Frameworks and NIS2
NIS2 is itself a legal frame, but it prescribes no particular framework. Established frameworks help you implement the requirements in a structured and demonstrable way – if you meet ISO 27001, for example, you already cover many of the points in Article 21 (risk management measures). What stays true is this: the legal duties apply whatever framework you choose, among them the reporting chain with an early warning within 24 hours, a notification within 72 hours and a final report after one month, and the registration duty, whose channel and deadline are set by each Member State.
Which framework fits?
That depends on size, sector and goals. What matters is less the perfect framework than consistent implementation – brought together in an ISMS. An example: An energy supplier in Germany with international customers chooses ISO 27001 for the certifiable external effect and uses IT-Grundschutz, the German standard, as a detailed catalogue of measures for the concrete work. The two complement each other, avoid duplicated effort and together supply the evidence that NIS2 and the competent authority ask for. A smaller organisation can instead start pragmatically with the IT-Grundschutz building blocks and certify later.

Frequently asked questions
What is a framework in IT security?
A framework in IT security is a proven set of rules or a standard that lays down how security and compliance are structured. A framework defines concrete requirements, measures and ways of working, and it bundles the experience of many organisations into a structure that can be audited. Well-known examples are ISO 27001, the German IT-Grundschutz published by the BSI and the NIST Cybersecurity Framework. Unlike a single tool, a framework describes how risk assessment, controls, roles and evidence work together across the whole life cycle.
Which frameworks help with NIS2?
The frameworks that help most with NIS2 are ISO 27001, as an internationally recognised, certifiable ISMS standard, and IT-Grundschutz, as a German national standard. Both already cover a large part of what Article 21 of NIS2 requires of risk management and technical security measures, and other Member States publish comparable frameworks of their own. The NIST Cybersecurity Framework is widely used as well. If you meet one of these frameworks, you can evidence many legal duties in a structured way instead of documenting every requirement from scratch.
Does NIS2 prescribe a framework?
No. NIS2 prescribes no particular framework and requires no certification. Established frameworks such as ISO 27001 or the German IT-Grundschutz do make the structured and demonstrable implementation of the legal duties easier, because they bring tested measures and an audit logic with them. The duties themselves apply whatever framework you choose: the reporting chain with an early warning within 24 hours, an incident notification after 72 hours and a final report after one month, and the registration duty, whose form and deadline each Member State sets for itself.
