Any encryption software for old WD Elements portable (WDBPCK0010BBK-EESN)?

I have an old WD Elements portable external HDD (2.5’’, 1 TB, USB 3.0) and I would like to ask you for any encryption software in order to protect my data in case my HDD is lost.

The model of my HDD is WDBPCK0010BBK-EESN

WD don’t make Encryption Software for WD Elements range.

There’s plenty of 3rd Party Encryption Software you can find doing a google search.
