Tenable One Open Connector

The following is not supported in Tenable FedRAMP Moderate environments. For more information, see the Tenable FedRAMP Product Offering.

The Tenable One Open Connector ingests asset and vulnerability data from third-party sources through one of the following methods:

  • Static file upload: Use this interface for manual flat file uploads.

  • Automated pull from cloud storage (S3): Use this method for automated discovery and import of data with continuous, scheduled syncs from remote storage.

Unlike predefined connectors, the Tenable One Open Connector gives you control over field mapping, deduplication logic, and data categorization.

Note:Tenable One Open Connector performs every initial synchronization as a Full Fetch to pull the entire dataset and establish a baseline for future incremental updates.
