Tenable On-Prem Connector

The Tenable On-Prem connector requires configuration to establish a connection with Tenable One. This procedure involves the generation of a pairing key within the Tenable One user interface, which is subsequently provided to the gateway during the setup phase. In essence, the Tenable On-Prem connector acts as a secure intermediary, allowing Tenable One to reach into closed networks without compromising their security posture. The key is that the gateway initiates the connection to Tenable One, so no inbound connections to the closed network are required.

Prerequisites and User Permissions

Before you begin configuring the connector, make sure to:

• Review the Tenable On-Prem Connector Quick Reference Guide

• Download the Tenable Core OVA file from the following link: https://www.tenable.com/downloads/tenable-appliance

• Ensure UDP port 51820 is open and pointing to your region-based server URL.

  Tip: You can find the region-based server URL on the Add Connector page when you create the Tenable On-Prem connector within Tenable Exposure Management.
