Frequently asked questions
The questions we hear most often about NIS 2.
ENISA Technical Implementation Guidance and NIS 2

Significant incident under NIS 2 and CIR 2024/2690

The shortest defensible summary of NIS 2 for the management body. What Article 20 requires, what auditors look for, what cannot be delegated.

Broader scope, new governance duties, tougher reporting, higher fines. The key shifts between Directive 2016/1148 and 2022/2555.
What is the BSI?
Federal Office for Information Security, established under §1 BSIG. Under NIS 2 the competent authority, single notification point and operator of the national CSIRT.
The BSI reporting portal
One platform, two NIS 2 obligations: first-time registration under §33 BSIG and incident notification under §32 BSIG. Access via ELSTER organisation certificate.
What 'proportionate' really means in Art. 21(1) NIS 2
Six factors decide what proportionate means in your case: risk exposure, size, likelihood and severity of incidents, societal impact, state of the art, cost of implementation.
What 'without undue delay' really means on the NIS 2 24-hour clock
Art. 23(4)(a) NIS 2 has two clocks, not one. Without undue delay AND within 24 hours, both starting at awareness. §121(1) BGB defines 'unverzüglich' as 'ohne schuldhaftes Zögern'.
What is an asset under NIS 2?
An asset under NIS 2 is anything that processes, stores or transmits information your operations depend on. Art. 21(2) and CIR 2024/2690 require an inventory; BSI 200-2 §8.1 allows grouping identical objects.
What is an ISMS and do I need one for NIS 2?
An ISMS is the way an organisation manages information security. NIS 2 never uses the word but Art. 21(2) requires exactly what an ISMS does. ISO 27001 certification is not mandatory.
