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.

Before you Begin

  • Install the OT Security Appliance.

  • Make sure that you have the license code (20 characters letter/numbers), which you received from Tenable when you ordered your device.

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).

    The License window appears with the three reinitialization steps.

    After you provide your Activation Code, your new license replaces your current license.
