A guide for professional-services teams in EMEA on evaluating GDPR-compliant client document sharing workflows, security controls, and portal requirements beyond generic file-sharing tools.
GDPR-compliant document sharing is more than encryption: it needs a lawful basis, EU residency, least-privilege access, an audit trail, and clean retention. Generic file tools leave most of that to you. This guide sets out the controls and a six-step workflow, with Alkmist as one GDPR-by-design option.
GDPR-compliant client document sharing keeps documents on EU-aware infrastructure, shares them under least-privilege access with encryption, logs every action, and deletes them on a defined schedule.
Sending a client document is easy; sending it in a GDPR-defensible way is not, once personal or financial data is involved. Generic file tools move the file and leave residency, access, logging, and retention to you.
The controls below are what an auditor or DPO will expect of client document sharing, and what separates a portal from a file tool.
These map to the GDPR principles and to the cloud-service risks you must manage.
Share only the personal data the engagement needs, on a clear lawful basis.
Keep documents on EU infrastructure to remove the cross-border transfer question.
Encrypt documents in transit and at rest, with clarity on key custody.
Least-privilege, role-based access so each user sees only what they should.
An immutable log of every access and change, attributable to an actor.
Controls to set how long documents are kept and to delete them at close.
A practical sequence for GDPR-defensible document sharing.
List the personal data your document sharing involves, and on what lawful basis.
Share through a portal that keeps documents and backups in the EU.
Apply least-privilege roles and controlled, revocable shares instead of open links.
Ensure encryption in transit and at rest, and screen files on upload.
Log every access and change immutably, and confirm you can export it.
Define how long documents are kept and delete them verifiably at engagement close.
