Field Masking and Export

If the source datastore contains masked fields, the platform applies the masking policy before the exported data leaves the platform. This page explains exactly what gets masked, what does not, and how to opt out per export.

What gets masked

Field masking only affects histogram values inside Field Profile exports.

  • Field Profile exports: in the histogram_buckets column, the bucket value for any field under field masking is replaced with a sentinel placeholder so the statistical distribution of sensitive values is not exposed.
  • Anomaly exports and Quality Check exports are not affected by field masking. They don't contain raw field values.

Where the masking is applied

Masking is applied while the platform prepares the export payload, before the data is handed off for writing. When masking is in effect, everything downstream (the write step, the network hop, and the enrichment datastore) only ever sees the masked values for fields designated as sensitive.

How to reveal masked values

Two ways to opt out per export:

  • In the Export Operation modal: when you select Field Profiles as the asset type, a Reveal Masked Values toggle appears. Turn it on to include the raw histogram values in the exported table.
  • Via the API: pass include_masked: true on the POST /operations/run request. See API for the full request shape.

The toggle defaults to off. Revealing masked values requires the Editor team permission on the source datastore.

Audit trail

Every revealed masked export is recorded in the Platform Audit. See Settings → Audit for the audit log.
