Why it matters

487M€in CNIL fines in 2025

GDPR compliance is not a technical issue — it's a business risk. Every undeclared cookie, every poorly collected consent is a vulnerability the CNIL can exploit during an audit. Our audits identify and fix these vulnerabilities before they become penalties.
