NIS2: Registration required by March 6, 2026

NIS2 registration deadline is March 6, 2026

Summary:

• Deadline March 6, 2026: Mandatory BSI registration for around 30,000 companies.
• ELSTER bottleneck: Registration requires an organization certificate - the application often takes several days.
• Immediate obligation: Reporting obligations (24-hour deadline) already apply, regardless of registration.

Focus: responsibility instead of delegation

With the NIS2 Implementation Act, cybersecurity explicitly becomes a management task. Management bears legal responsibility for the approval, monitoring and effectiveness of the measures. It must actively monitor implementation anddemonstrably continue their training. The operational implementation can be delegated - but the overall legal responsibility cannot. Violations of registration, security or reporting requirements can result in significant fines.

The registration process: two steps to demonstrate compliance

Do not wait until the deadline of March 6, 2026. The process is administratively complex:

1. Company account(MUK): The basis is an ELSTER organization certificate. Check immediately whether this is available (usually in the tax department).
2. BSI portal:Reporting in the central portal is only possible with MUK access. Sector classification and 24/7 contact points are stored here.

24 hours to report: The new time calculation

When there are significant security incidents, the clock is ticking:

• 24 hours: First report (early warning) after it becomes known.
• 72 hours: Detailed assessment of the incident.
• 30 days: Final root cause analysis report.

Your incident response processes must be so robust that reports can be made in a legally compliant manner, even on public holidays.

Strategic Roadmap: Your next steps:

1. Status quo MAJKE: Check access to the organization certificate today.
2. Governance update:Ensure that NIS2 is regularly addressed at board level. Document your monitoring activities to protect against liability claims.
3. Supply Chain Check:Anticipate NIS2 requests from your customers and prepare your ownRequirements for your suppliersbefore.
