Annex I
The list of 11 sectors under NIS2 considered most critical, whose in-scope organisations are classified as essential entities.
Explained in depth: Which sectors NIS2 covers
Covers energy, transport, banking, financial market infrastructure, health, drinking water, waste water, digital infrastructure, ICT service management, public administration, and space. Being listed in Annex I does not by itself put an organisation in scope — the size thresholds still apply — but a large organisation in one of these sectors is normally an essential entity, with proactive supervision and the higher penalty ceiling. Our sectors page breaks the list down subsector by subsector, and the energy deep-dive shows what it means for one of them in practice.
