LEYR

Leyr is the EU-sovereign AI security layer for security-conscious European companies whose teams use ChatGPT, Claude and Gemini every day.

The risk isn't only a leak — it's a transfer. Every prompt containing a customer record, contract or patient note is personal data crossing to a US provider, exactly what GDPR Chapter V governs. Network firewalls and email DLP can't see a chat box; the US-built DLP tools that can still run on US infrastructure, so the data crosses anyway. Leyr installs as a browser extension and catches sensitive data in the composer, before Send. Your policy blocks, redacts, warns or logs — per team, per data class. Detection and classification run entirely in the EU: no US sub-processor in the data path. Self-hosting is available. 

Because PII is redacted before transfer, the Chapter V obligation never arises — and every event is logged as audit evidence for your DPO.

Keep ChatGPT. Lose the data leaks!
