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: A manual flat file upload interface

  • Automated pull from cloud storage (S3): An automated discovery and import of asset and vulnerability 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.
