Das deutsche NIS2-Gesetz ist nun in Kraft getreten: Was Start-ups und KMU tun müssen

Germany's NIS2 Law Is in Force: Here's What It Means

On December 6, 2025, Germany's NIS2 Implementation Act (NIS2UmsG) entered into force, transposing the EU's NIS2 Directive into national law more than a year after the original deadline. The Act substantially revises the BSI Act (BSIG) and expands the scope of regulated entities from roughly 4,500 to around 29,500, a sevenfold increase that pulls thousands of medium-sized companies into the supervision of the Federal Office for Information Security (BSI) for the first time.

Small businesses with fewer than 50 employees and under €10 million in turnover generally remain exempt. Midsize startups and SMBs above those thresholds operating in in-scope sectors, including digital services, manufacturing, health, transport, and data processing, are very likely covered and should act now.

Are You in Scope? Two New Categories to Know

The revised BSI Act classifies regulated organizations into two tiers, mirroring the NIS2 Directive:

• Particularly important entities (besonders wichtige Einrichtungen), equivalent to NIS2's "essential entities."
• Important entities (wichtige Einrichtungen), equivalent to NIS2's "important entities."

Classification is based on a combination of sector and size. If your company has more than 50 employees or exceeds €10 million in both annual turnover and balance sheet total, and operates in one of the sectors named in Annexes 1 or 2 of the BSI Act, you are likely in scope. Companies must self-assess and document their applicability, the BSI does not notify you.

What NIS2 Requires of In-Scope Companies

• Risk management measures. You must implement a formal cybersecurity risk management framework covering policies, incident handling, business continuity, supply chain security, access control, training, and vulnerability management. Adopting an ISO 27001-aligned information security management system (ISMS) covers most of these requirements and significantly simplifies compliance.
• Mandatory BSI registration. In-scope entities had to register via the BSI portal (live since January 6, 2026) by March 6, 2026. If you missed that deadline, register immediately, supervisory authorities can request evidence of self-assessment at any time.
• Incident reporting on a strict timeline. Significant incidents must be reported to the BSI within 24 hours of becoming aware of them, followed by an update within 72 hours and a final report within 30 days. You need an incident response plan and monitoring in place now.
• Leadership accountability. Management bodies must approve and oversee cybersecurity measures. Executives are required to complete cybersecurity training at least every three years. Where corporate law liability rules exist, managers can be held personally liable for compliance failures. Cybersecurity is now a boardroom responsibility, not just an IT concern.
• Enforcement and penalties. Fines reach up to €10 million or 2% of global annual turnover, whichever is higher. The BSI has audit powers and can issue binding instructions to fix deficiencies.

Why the Clock Is Already Ticking

Unlike most EU regulations, the NIS2 Implementation Act came into force with no transition period. Obligations apply immediately. The March 6, 2026 registration deadline has passed, meaning any in-scope company that hasn't yet registered, self-assessed, and started implementing risk management measures is already non-compliant.
