Make healthcare data safe to share.
Upload a file containing PHI. PDM masks identifiers in structured columns and free text, then returns the protected file with a receipt showing what was removed.

PHI isn’t always in a PHI column.
Names, dates of birth, and medical record numbers are easy to spot when they have their own columns. The harder problem is free text.
A patient name inside a clinical note. An MRN mentioned in a comment. A date of birth buried in a case description.
You can’t just remove the whole field — the useful information needs to stay while the PHI comes out.
HIPAA Safe Harbor requires eighteen categories of identifier to be removed, in structured columns and free text alike. PDM handles both, in one pass.
A file problem, not a platform problem.
If you need continuous discovery and monitoring across your organization, you need an enterprise data governance platform.
But sometimes you just have a file that needs to go somewhere — to a research partner, vendor, analytics team, or test environment — without the PHI.
That’s what PDM is for.
Upload the file. Download the protected version and its receipt. No connectors. No deployment. No implementation project.

Mask
Identifiers in structured columns and free text are processed together.
- 4
Document
You get a processing receipt showing what was masked, by category, tied to the input and output files by cryptographic hash.

Your masked file and receipt.
If healthcare data is detected, we ask you to confirm the Business Associate Agreement before payment — or to choose standard processing instead.
Proof you can keep.
Masking the data is one part of the job. Showing what you did is the other.
Every PDM job comes with a receipt showing what was masked by category and tying the receipt to that specific input and output. HHS guidance on de-identification says to document the removal of each identifier category — that’s what the receipt is.
