On-ingest Postgres PII guard via load webhook

Fires the moment a new table loads into Postgres, samples every column, and immediately revokes app-role access to any table with unmasked PII before downstream services can read…

How it runs

The automated pipeline, trigger to output.

  • TriggerLoad-complete webhook with table nameHTTP webhook
  • ActionSample columns of the new Postgres tablePostgreSQLPostgres
  • LogicClassify; proceed only on PII match
  • ActionRevoke app-role access to quarantinePostgreSQLPostgres
  • OutputAnnounce catch in SlackSlack

What it does

Instead of scanning on a timer, this template hooks your ingestion pipeline: when a load job finishes it calls a webhook with the new table name. The workflow samples each column, classifies for sensitive data, and if it finds unmasked PII it revokes the application role's access on that table right away, so no API or dashboard can read the data before review. The detection is announced in Slack.

When to use it

Use it when freshly loaded tables become readable by production services within minutes and a once-a-day scan is too slow. Best when your loader can hit a webhook on completion.

How it works

  1. 1The load pipeline posts the new table name to the webhook trigger.
  2. 2Query Postgres for that table's columns and sample values from each.
  3. 3Classify samples and branch only when PII is present.
  4. 4Revoke the application role's privileges on the table to quarantine it.
  5. 5Post the table, matched columns, and categories to Slack for the on-call data owner.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect HTTP webhookTrigger any URL on agent actions.
  2. 2
    Connect PostgresAny Postgres URL — query, write, migrate.
  3. 3
    Connect SlackChannels, DMs, threads, mentions.
  4. 4
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  5. 5
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  6. 6
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
