KRITIS (Kritische Infrastrukturen) is Germany’s national regulatory framework for the security and resilience of critical infrastructure. It is enforced by the BSI (Bundesamt für Sicherheit in der Informationstechnik — Federal Office for Information Security) and, for physical resilience, by the BBK (Bundesamt für Bevölkerungsschutz und Katastrophenhilfe — Federal Office of Civil Protection). The framework is now governed by two primary laws: the NIS2-Umsetzungs- und Cybersicherheitsstärkungsgesetz (NIS2UmsuCG), which rewrote the BSI-Gesetz and entered into force on 6 December 2025, and the KRITIS-Dachgesetz (KRITISDachG) for physical resilience, in force since 17 March 2026. Together they transpose the EU NIS2 Directive and CER Directive into German law. The scope expanded dramatically: from approximately 4,000 regulated entities under the previous IT-Sicherheitsgesetz 2.0 to around 30,000 entities now classified as either “besonders wichtige Einrichtungen” (particularly important, equivalent to NIS2 essential) or “wichtige Einrichtungen” (important). KRITIS applies to organizations in 18 sectors (energy, water, health, finance, transport, digital infrastructure, space, public administration, manufacturing, etc.) meeting defined size thresholds. Compliance is mandatory with no transitional period: entities must register with the BSI, implement risk management (§30 BSIG), report security incidents within 24 hours (§32), and management is personally liable (§38) for overseeing cybersecurity measures. Penalties reach up to €10M or 2 % of global turnover for particularly important entities.
