Methodology
How the numbers are produced.
These figures come from the offline detection engine running against a published, versioned corpus — not from customer traffic. The corpus and the runner are downloadable so you can reproduce the run yourself. Live production enforcement adds a model-scored stage on top of these local checks.
Where it still misses
One case in the current corpus is a known miss: a free-form postal address with no other identifiers is not reliably flagged as PII by the local pattern layer. We publish it because a vendor that never shows you a miss has not shown you a test.
