Four Indian PII detectors on three datasets, including ones we did not write
Every PII tool looks good on its own test data. credgate's benchmark has always been a corpus we generated ourselves, and our rules were refined on part of it - so its numbers say more about our templates than about the notes, logs and chat transcripts a bank actually has.
So we ran credgate, MaskFlow, Microsoft Presidio and Kavach PII on two public Indian PII datasets written by other people, alongside our own, with the same scoring for every tool. This post is what we found: where credgate is strong, where it clearly trails, and the three detection fixes the public data led to.
