Configure the Tenable Connector

The Tenable Connector provides all API interactions between your Tenable applications (OT Security, Tenable Vulnerability Management, or Tenable Security Center) and ServiceNow instance.

Note: In ServiceNow, you must have the x_tsirm_api_access admin role to perform the basic connector setup process.

Note: The ServiceNow configuration only supports Tenable Security Center versions 5.7 and later.

Before you begin:

For Tenable Vulnerability Management:

Required User Role: Administrator

• You must have your Tenable Vulnerability Management API keys.

  Note: For your Tenable Vulnerability Management integration:

  • Generate an API key in Tenable Vulnerability Management to complete the configuration.  See the Tenable Vulnerability Management user guide for instructions on how to generate an API key. (Do not use this API key for any other third party or custom-built application or integration. A unique API key is a requirement for each installed instance of the integration.)

For Tenable Security Center:

Required User Role: Security Analyst

For OT Security:

Required User Role: Read Only
