  • Notify the BSI's and the Bundesamt für Bevölkerungsschutz und Katastrophenhilfe's joint reporting office without delay, and in any event within 24 hours of becoming aware of a significant security incident, with an early warning stating whether the incident is suspected to be unlawful or malicious or to have cross-border effect.NIST CSF 2.0RS.CO-02

Criminal exposureNo

Private right of actionNo

Criminal exposure note

Section 65's penalty regime for a Section 32 infringement is an administrative fine (Ordnungswidrigkeit); the Act creates no criminal offence for a failure to report, its Part 8 consisting of Section 65 alone.

Penalty structure

The same Section 65(5) No. 1(a) and (b), Section 65(6) and Section 65(7) tiers that govern a Section 30 infringement govern a Section 32(1) or 32(2) infringement: EUR 10,000,000 or, above EUR 500,000,000 group turnover, up to 2 percent of turnover for an essential entity, and EUR 7,000,000 or up to 1.4 percent of turnover for an important entity.

Section 32 requires a besonders wichtige Einrichtung or wichtige Einrichtung to notify a joint reporting office run by the BSI and the Bundesamt für Bevölkerungsschutz und Katastrophenhilfe of a significant security incident on a graduated clock.

It requires an early warning within 24 hours of becoming aware of the incident, stating whether it may be unlawful or malicious or have cross-border effect, followed by a full notification within 72 hours that confirms or updates that assessment with the incident's severity, impact and any indicators of compromise, and an intermediate report on the BSI's request.

A final report is due within one month of the 72-hour notification, or, if the incident is still ongoing at that point, a progress report followed by a final report after its resolution, transposing NIS2 Article 23. A Betreiber kritischer Anlagen must additionally report the type of critical facility and critical service affected and the incident's effect on that service. Section 32(1) provides that the duty applies at the earliest from the establishment of the reporting channel.

The BSI states that the reporting duties have applied since . The BSI-Portal serves as the reporting office for serious security incidents, and an entity affected from that suffers a significant incident before it has registered there reports it through an online form.
