Anonymization
Automatically detect and mask personal data. GDPR-compliant text analysis with automatic PII detection.
One name in 10,000 texts
Finding personal data in free-text responses is like finding a needle in a haystack. One overlooked name, one forgotten email address – and you have a GDPR problem. Manual review is neither practical nor reliable.
- GDPR fines up to €20M or 4% of annual revenue
- Reputation damage from data breaches
- Manual review misses an average of 15% of PII

Choose the right approach
Depending on your requirements, you can fully anonymize, consistently pseudonymize, or generalize for maximum analyzability.
Redaction
Complete removal – the text is replaced by [REMOVED] or similar placeholders.
John Smith → [NAME]Ideal für: Maximum security when the original value doesn't matter
Pseudonymization
Consistent replacement – the same person always gets the same placeholder.
John Smith → Person_A (everywhere in the text)Ideal für: When you need to preserve relationships between people
Generalization
Replacement with general categories – context is maximally preserved.
john@company.com → [EMAIL]Ideal für: When context matters, but not the exact data
