Framework overlap

Does ISO 27043 cover NIS2 Directive?

You hold ISO 27043 and have been told to do NIS2 Directive. Here is how much overlaps, control by control.

75% of NIS2 Directive you already have

ISO 27043 already covers about 75% of NIS2 Directive, leaving 2 of 8 controls as genuinely new work.

Already covered 4 Likely covered 2 New work 2

What is genuinely new work

Nothing in ISO 27043 reaches these. This is the list to scope.

NIS2D-4
Management Body Accountability and Training - Articles 20 and 26
NIS2D-7
Penalties, Enforcement, and Article 32-34 Supervision
Show the 6 you already have
NIS2D-1
NIS2 Scope, Essential and Important Entities, Sectoral Coverage
NIS2D-2
Cybersecurity Risk Management Measures - Article 21
NIS2D-3
Incident Reporting Obligations - Articles 23 and 30
NIS2D-8
Cross-Border Coordination, ENISA, CSIRTs Network, and CER Coordination
NIS2D-5
Supply Chain Security - Article 21(2)(d) and 22
NIS2D-6
Vulnerability Disclosure and CVD Programme - Article 12 and 21

How this is calculated

Already covered means a mapping runs from a control in ISO 27043 to that control. Likely covered means no direct mapping exists but both frameworks map to the same control in a third standard. New work means neither. We keep those separate rather than adding them into one friendlier number, because blending them would present a two-hop inference as a verified fact.

Coverage is not symmetric. Run it the other way and you will get a different number; both are correct.

From 332,959 cross-framework control mappings across 723 frameworks, 531 of them verified against their source documents. It does not tell you that you are compliant: a mapped control means the two standards ask for the same thing, not that you have done it.
