Tenable One OT Exposure EM License Workflow

Licenses for Tenable accounts are calculated based on the number of unique IPs in the system. Each IP requires a separate license. For example, even if more than one device shares the same IP address, multiple devices connected to the same backplane that share the same three IPs, the licenses can still be based on the number of IPs. In this case, you need three licenses, regardless of the number of devices.

After you install Tenable One OT Exposure EM, the next step is to activate your license.

Note: To update or reinitialize your Tenable One OT Exposure license, reach out to your Tenable Account Manager. Once your Tenable account manager updates your license, you can update or reinitialize your license.

Before you Begin

  • Install the Tenable One OT Exposure EM Appliance.

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