Exfiltrating Data In TDE-Protected Databases

Tom LaRock shows how to exfiltrate data in a database protected by Transparent Data Encryption:

Enabling TDE does not protect your BACPAC files, just your database backups. If you are relying on TDE to protect your data at rest then allowing users to create BACPAC files will put you at risk. But no more risk than any other user choosing to run a SELECT statement and save the data somewhere (or perhapsjust use PowerBI to open a connection and import to Excel).

TDE has a single, specific purpose.  If you want something more stringent, SQL Server 2016 Always Encrypted might be an option.
