Standard Edition of
SQL Server 2016.
Is it possible to enable TDE?
I understand that it was an enterprise feature but it is now a feature for
SQL 2019 Standard and therefore I wondered if there was a way to add this feature for
SQL 2016 Standard now?
Nope. You can see the full feature list here.
There were several things opened up for 2016 in Standard with the release of SP1. TDE was not one of them.
