Where is that data stored? With the wide range of data storage options (On-prem, cloud, multi-cloud) it's far from trivial to know where all your corporate data is being kept, in which format, who's responsible? A related question is where sensitive data is being stored.
In this session you can see how Microsoft Purview (former Azure Purview) collects meta-data from on-prem as well as different cloud sources, identifies sensitive data and makes it easily searchable.
