Penetra makes it possible to use AI on sensitive documents without exposing personal data.

Companies that handle confidential documents face a hard limit. Data protection law like the GDPR, combined with professional confidentiality rules such as Germany's BRAO and Section 203 StGB, restricts uploading documents that contain personal or privileged information into AI tools like ChatGPT or Claude. Similar regulations exist in nearly every jurisdiction, from attorney-client privilege to medical and financial confidentiality. The result is the same everywhere: teams either avoid AI entirely, or take on legal risk by uploading sensitive data anyway.

Penetra solves this. Our tool automatically anonymizes personal data such as names, addresses, emails and IBANs before documents ever reach an AI model. Once processing is done, the original data can be restored. This means companies can finally search, analyze, and work with their documents using AI, fully compliant with data protection and confidentiality law.

We work with law firms, insurers, data protection consultants, healthcare institutions, and any organization that handles confidential documents at scale.

Penetra is being built in Munich.
