GDPR Compliance Guide for German Businesses: Checklist & Key Requirements

GDPR (DSGVO) fines hit an all-time high in 2025. Combined with NIS2, the EU AI Act, and DORA adding new requirements, German businesses face an increasingly complex compliance landscape. Here's your practical checklist.

Key DSGVO Obligations

1. Lawful Basis for Processing

Every data processing activity needs a legal basis: Consent, Contract, Legal obligation, or Legitimate interest.

2. Data Protection Officer (DPO)

Mandatory for companies with 20+ employees regularly processing personal data. Must be independent and report directly to management.

3. Breach Notification

72-hour deadline to notify the supervisory authority. Notify affected individuals if high risk.

4. Data Subject Rights

Handle requests within 1 month: access, rectification, erasure ("right to be forgotten"), data portability.

5. Records of Processing Activities

Maintain written records including purpose, data categories, recipients, and retention periods.

Compliance Checklist

• Identify all personal data processing activities
• Document legal basis for each activity
• Appoint a DPO if required (20+ employees)
• Implement technical and organizational measures (TOMs)
• Create and maintain privacy policies
• Establish breach notification procedures
• Conduct DPIAs for high-risk processing
• Ensure data processor agreements (AVVs) are in place
• Train all employees on data protection
• Implement data subject rights request procedures

Penalties

Violation Level	Maximum Fine
Lower tier	10M EUR or 2% annual revenue
Upper tier	20M EUR or 4% annual revenue

New Requirements

NIS2 Directive (2024-2025)

Expanded scope, mandatory incident reporting, management liability for cybersecurity.

EU AI Act (Enforcement from Aug 2026)

Risk classification of AI systems, transparency requirements, mandatory human oversight.

DORA (Financial sector, Jan 2025)

ICT risk management framework, digital operational resilience testing.

Secure Compliance Documentation

When sharing compliance documents — privacy impact assessments, breach reports, employee data processing records — use secure channels. LOCK.PUB lets you create password-protected memos for sharing sensitive compliance documentation that self-destruct after access, ensuring audit trails don't become data liabilities.

Store your DSGVO compliance checklists and sensitive internal documents securely with LOCK.PUB password-protected, expiring links rather than unencrypted email attachments.

DSGVO compliance isn't optional — it's the law. Start with the checklist above, appoint a DPO if required, and document everything.
