Microsoft’s Compliance Manager is intended to help cloud tenants cope with regulations like ISO 27001 and GDPR. The Compliance Manager (preview) has a nice dashboard, but it is passive and offers no practical way to organize the actual work. But Office 365 has Planner and Teams, and it is easy to create the necessary collaboration structure to allow people to work on GDPR controls.
