> TL;DR: Legaltechs have a dual obligation: GDPR + professional secrecy. A breach = ethical violation.

The dual obligation

Legaltechs are subject to GDPR AND professional secrecy. A security breach violates both.

Art. 226-13 Penal Code

Revealing information covered by professional secrecy: 1 year imprisonment and €15,000 fine. This is criminal, not administrative.

What we find

Legal documents in public S3 buckets

APIs exposing case files without per-case access control

Client portals without strong authentication

Key Takeaways

Identify and test your exposed attack surfaces before a third party does.

Client-side security controls never replace server-side validation.

Regular audits are more effective than one-time checks — vulnerabilities appear with every deployment.
