There are two ways to track where data ends up. There is an extensive search functionality where you can search for data that matches specific criteria. However, if you want to analyze the data in less depth, there are some blocks that offer a clear overview as well.
The blocks with ‘sharing domains’ and ‘shared external’ offer a quick glance into your domain. They show – you guessed it – the domain files are shared with and with which mail addresses the most files are shared. The blocks are quite useful for three purposes:
1) to have an overview of what’s happening within your domain,
2) to identify where possible data exposure could occur and
3) to track remarkable changes.
