OT Security License Activation

Objective: Unlock system features with license activation.

Tenable calculates licenses based on the number of unique IPs in the system. Each IP address requires a separate license. For example, Tenable bases licensing on the number of unique IPs, even if multiple devices share the same IP address, or if several devices connected to the same backplane share the same three IPs. Therefore, you need three licenses, regardless of the number of devices.

After you install the OT Security Appliance, you can activate your license.

Note: To update or reinitialize your OT Security license, contact your Tenable Account Manager. Once your Tenable account manager updates your license, you can update or reinitialize your license.

For information about deploying and licensing Tenable OT Security for Tenable One, see the Tenable One Deployment Guide.

Reinitializing your license removes your current license from the system and activates a new license, similar to the license activation during your system startup. If you need to reinitialize your license (that is, if you receive a new license), use the following procedure.

Before you Begin

  • Your Tenable account manager must have already issued your new license in their system and provided you with a License Code (20 characters letter/numbers).

To reinitialize your license:

    A confirmation window appears.

  3. Click Reinitialize.

    The License window appears with the three reinitialization steps.
