How to Prepare Your Company for a GDPR Audit?
Practical checklist for GDPR audit preparation. Learn what documents you need, what mistakes to avoid, and how to ensure compliance.

A GDPR audit can be stressful, but with proper preparation, there's nothing to fear. In this guide, you'll find a practical checklist that will help you prepare your company for compliance verification.
Why Is GDPR Still Important?
Since May 2018, GDPR has been the most important regulation governing personal data protection in Europe. Violations can result in fines of up to 4% of annual turnover or 20 million euros.
GDPR Audit Checklist
1. Documentation
Every company must have:
- Privacy Policy - clear and understandable
- Records of processing activities (Article 30)
- Data processing agreements with subcontractors
- Risk assessment documentation
- Procedures for handling data subject requests
2. Technical Measures
| Area | Requirements |
|---|---|
| Access | Role-based access control (RBAC) |
| Encryption | Data encrypted at rest and in transit |
| Backups | Regular, tested, encrypted |
| Monitoring | Logging of data access |
| Devices | Mobile Device Management (MDM) |
3. Organizational Measures
- Employee training - regular, documented
- Data Protection Officer (DPO) - appointed if required
- Data breach procedures - 72-hour notification
- Data retention policy - defined retention periods
Most Common Mistakes
- Outdated documentation - policy created in 2018 and never updated
- No processing records - "we're a small company, we don't need it"
- Informal consent - verbal agreements without evidence
- No employee training - everyone processes data, no one knows the rules
- No incident procedures - "we've never had a breach"
Pre-Audit Checklist
Before the audit, verify:
- Do you have current records of processing activities?
- Are data processing agreements signed with all subcontractors?
- Is the privacy policy updated and accessible?
- Is employee training documented?
- Do you have data breach procedures?
- Are IT systems protected (encryption, backups, access control)?
- Can you fulfill data subject requests (access, deletion, portability)?
What Can an Auditor Check?
- Documentation - completeness and currency
- Processes - actual implementation
- IT Systems - technical security
- Employees - awareness and training
- Incidents - breach register and responses
