Essential Entity
An organisation classified under NIS2 Annex I sectors that faces the strictest supervisory regime and highest penalty ceiling.
Explained in depth: Who NIS2 applies to
Typically large enterprises (250+ employees or €50M+ turnover) in sectors like energy, transport, banking, and health. Essential entities face proactive (ex-ante) supervision, meaning authorities can audit them before any incident occurs, and a fine ceiling of €10 million or 2% of global annual turnover, whichever is higher.
