Install Tenable Core on Hardware

You can install Tenable Core + Tenable OT Security directly on Tenable-provided hardware using an .iso image. When you install Tenable Core via an .iso image on your computer, Tenable Core replaces your existing operating system with the Tenable Core operating system.

Tip: Tenable OT Security offers turnkey appliances that ship directly that come pre-imaged. This option is much easier to use and deploy, with a faster time to value. However, you can also source your own hardware and apply our ISO image to it. If you supply your own or choose to use ours, please refer to our Tenable OT hardware specs as a guideline or best practice. All components of Tenable OT Security, the ICP EM and Sensor can be ran on any hardware that meets the specs.

Before you begin:

  • Confirm your environment supports your intended use of the instance, as described in License and System Requirements.

  • Confirm your internet and port access will support your intended use of the instance, as described in Access Requirements.

  • Confirm that Tenable Core + Tenable OT Security was not preinstalled on your hardware for any new instance of Tenable Core + Tenable OT Security. Not all new instances require manual installation.

To install Tenable Core + Tenable OT Security on hardware:

  1. Download the Tenable Core Tenable.ot Installation ISO file from the Tenable Downloads page.

  2. Boot the .iso. For more information, see your environment documentation.

    Caution: Booting the .iso replaces your existing operating system with the Tenable Core operating system.

    Tip: To monitor the progress of the installation on hardware that uses a serial console, select Install Tenable Core using serial console from the boot menu. For more information about the OT Security serial console, see the OT Security User Guide.
