Tenable FedRAMP Moderate: Okta IdP

One of the most common IdPs used to configure SAML with Tenable FedRAMP Moderate is Okta. The following steps guide you through the configuration process from start to finish.

Important: These configuration steps apply to the following Tenable FedRAMP Moderate applications:
  • Tenable Vulnerability Management FedRAMP Moderate

  • Tenable Web App Scanning FedRAMP Moderate

Manual configuration requires the following:

  • Login URL: A custom URL provided by Tenable in the following format:

    https://fedcloud.tenable.com/saml/login/PLACEHOLDER
  • Audience URI (SP Entity ID): A custom ID provided by Tenable in the following format:

    TENABLE_IO_PLACEHOLDER

    If the customer requires more than one container, Tenable requires different SP Entity IDs for each container.

  • A certificate within the SAML metadata object that matches the data originally sent to Tenable.

    Note: Tenable does not support the use of multiple certificates and only extracts the first certificate from the metadata object. If the object includes multiple certificates, you must specify which certificate to use if it is not the first one listed.
