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?
