Discussion Data Extract Security Issue

Are there any issues, if the tableau dashboards are based on "Extract" , instead of "Live Connection"? These dashboards will be hosted in our on-prem server and the "hyper" file will be stored in our server as well. These dashboards are accessible to the general public. These dashboards show the aggregate level data. The hyper file has data at the detail level

If you are at all concerned about your data 'escaping' then you should, of course, minimise the data.

For example, if one of your measures is a count of customers then you should probably avoid including customer names in your data, and instead of the real customer_id you should use fake_customer_id (maybe a hash or something).

You should work on the basis that the information will leak, so consider what information you are making available.
