Atlan connects to ALTR using API credentials to retrieve classification metadata and map it to existing assets in Atlan.

Data flow​

Security​

Atlan imports metadata only. Atlan doesn't read row-level data from your source tables through ALTR.

  • Read-only operations: ALTR API calls used by the connector are read-only and don't change ALTR configuration or classification jobs.
  • Credential protection: ALTR API credentials are encrypted at rest and in transit.
  • Metadata-only import: Atlan imports classification outputs and mapping information, not source records.

For example, if ALTR classifies a table as containing sensitive data, Atlan imports that classification result and applies mapped governance tags. Atlan doesn't ingest the table's underlying records through this integration.
