Configure the Offered Tenable Nessus Agent Version

The Automatic Updates setting allows Tenable Nessus Manager to automatically update the Tenable Nessus Agent version it offers to its linked agents to upgrade to based on the manager's update plan. Alternatively, you can turn off Automatic Updates and configure the offered Tenable Nessus Agent version manually.

Note: If you want to prevent linked agents from downloading any software updates, you need to create a permanent freeze window in addition to disabling Automatic Updates. Disabling Automatic Updates only blocks Tenable Nessus Manager from updating the version it offers the linked agents. If Tenable Nessus Manager already downloaded a new agent version to offer the linked agents, the linked agents upgrade or downgrade to that new version. To avoid this, create and enable a permanent freeze window with the Prevent software updates setting turned on. For more information, see Create a Freeze Window.

To enable or disable the Automatic Updates setting:

  1. In the top navigation bar, click Sensors.

    The Linked Agents page appears. By default, Linked Agents is selected in the left navigation menu and the Linked Agents tab is active.

  2. In the left navigation bar, click Agent Updates.

    The Agent Updates page appears.

  3. Under Automatic Updates, select or clear the Enable Agent Updates check box.

  4. Click the Save button.

    Tenable Nessus Manager saves the setting.

Sometimes, such as after you configure the agent update plan or after you turn off Automatic Updates, you may want to update the Tenable Nessus Agent version that Tenable Nessus Manager offers manually.

To update the offered Tenable Nessus Agent version manually:

  1. In the top navigation bar, click Sensors.

    The Linked Agents page appears. By default, Linked Agents is selected in the left navigation menu and the Linked Agents tab is active.

  2. In the left navigation bar, click Agent Updates.

    The Agent Updates page appears.

  3. In the upper-left corner of the page, click the Manual Software Updates button.

    The Update Provided Agent Version Now window appears.

    Note: The Manual Software Update button updates the offered Tenable Nessus Agent version based on the saved agent update plan. For example, if you set the plan to GA releases, save, and click the button, your offered Tenable Nessus Agent version updates to the latest GA version. The button does not show if you selected Disable agent version updates.

  4. Click the Continue button.

    Tenable Nessus Manager updates the version it offers to Tenable Nessus Agents from the Tenable Nessus feed.
