# Does NIS2 require a specific security tool, such as intrusion detection?

No. NIS2 is technology-neutral: Article 21 requires appropriate and proportionate measures that take into account the state of the art, relevant standards and the cost of implementation, but it names no product category. In practice you cannot handle incidents (Article 21(2)(b)) or report them on time (Article 23) without some way of detecting them, so most entities use a combination of endpoint protection, log collection and network detection, scaled to their risk. National laws can be more specific for some entities: Germany's section 31(2) of the BSIG requires operators of critical installations to use systems for attack detection, while other particularly important and important entities fall under the general measures of section 30. Choose tools by the risks in your assessment, and document why.

General information, not legal advice. National laws can add to the EU texts quoted here, for example deadlines, forms or reporting channels: check your own country's rules.
