Can you please be a little more specific about the certifications?

These days secure deletion at file system level is almost impossible to achieve
since you don't have full control of the storage stack.
I know, I know, In the raw flash case we have, but still. It makes
things very complicated.

A common approach do delete a file in a secure way is having it
encrypted and upon deletion
you forget the key.
Wouldn't that work for you too?
