Activity

Annex I is sectors of high criticality. Annex II is other critical sectors. If more than one activity fits, run the check again. Confirm the stricter result with the competent authority.

Size

Use annual figures in euro. Headcount is the number of employees (annual work units if you have them). Medium means 50 or more employees, or turnover and balance sheet total both above EUR 10 million. Large means 250 or more employees, or turnover above EUR 50 million and balance sheet total above EUR 43 million. Simplified: control can also arise from voting rights or the right to appoint the board, some investors at 25–50% don't count as partners, and a change of size category takes effect only after two consecutive years (Rec. 2003/361/EC Annex, Art. 3–4).

Linked and partner enterprises

Add 100 percent of a linked enterprise: a holding or control above 50 percent. Add only your share of a partner enterprise: a holding from 25 to 50 percent. A holding below 25 percent stays out of the total. This is the simple version of Recommendation 2003/361/EC. NIS2 says a public-sector shareholder does not by itself change the size test.

Country

Choose a Member State to see national notes. Austria, Belgium, Finland, Germany, Ireland, Italy, Luxembourg, the Netherlands, Poland, Slovenia and Sweden show national notes. Every other country says that national details are coming soon.

Possible national designation

Optional. Tick a box only if it might apply. The checker cannot see a Member State's list, so the result will tell you to check the designation.

Indicative result only. This is not a legal determination of your NIS2 status and not legal advice. Your status depends on national law and on any identification by your Member State. Confirm it with the competent authority or a qualified adviser.

Who is covered

This checker uses the Directive's medium and large enterprise test (Recommendation 2003/361/EC). Size-independent entities follow Article 2(2). Simplified: control can also arise from voting rights or the right to appoint the board, some investors at 25–50% don't count as partners, and a change of size category takes effect only after two consecutive years (Rec. 2003/361/EC Annex, Art. 3–4).

Registration

Self-registration ran from 7 May to 3 October 2026 via S46 (wykaz-ksc.gov.pl). That date has passed. Entities entered ex officio have six months after the summons.

Incident reporting

Incident reports go to the national CSIRTs. The Directive clocks are an early warning within 24 hours, an incident notification within 72 hours, and a final report no later than one month after the incident notification.

How GRCompliance helps

GRCompliance can hold the Article 21 measures, the risk register and the incident clocks on infrastructure you control. It does not file your Polish registration and it does not decide your legal status.
