Google Drive is hosted on Google's global infrastructure, without guarantee of EU residency for at-rest data. Workspace Enterprise enables regional policies at significant cost. GDPR-compliant at standard level, yet the mixed personal/professional account pattern generates practical issues: the same Google email address used for private Gmail, YouTube, Maps, also contains patient scans.
CadCamCloud is hosted exclusively in the European Union (Hetzner DE, Wasabi EU). No mix with personal accounts: every user is a professional identity linked to a practice or lab. Immutable PDF/A for each submission, conformant with AGID Guidelines. Structured audit log for every access to healthcare data.
