EU Data Room Compliance Topics

A virtual data room (VDR) used for European transactions has to satisfy several overlapping regulatory regimes: the EU General Data Protection Regulation (GDPR), sectoral rules for financial services (DORA, BaFin, FINMA, FCA, AMF), cybersecurity duties under the NIS2 Directive, and recognized control frameworks such as ISO 27001 and BSI C5.

The articles below explain each topic, the obligations it places on a VDR provider, and how to verify compliance during procurement.
