De-identification lowers risk. It doesn’t erase it. An unusual detail mentioned in passing, or context that only an insider would recognize, can occasionally survive even careful review.
That’s why sensitive categories are excluded entirely rather than cleaned, why you set the scope and can leave out anything you’re unsure about, and why you can ask to see a de-identified sample before anything is delivered.
It’s also why nothing is final until you sign. If the residual risk doesn’t sit right with you, you can walk away.
