Installation Preparation

To install cognitix Threat Defender on physical hardware (i.e. appliance), you need an installable image.

If you purchase Threat Defender with a genua hardware appliance, you also receive a ready-to-use USB installer drive. Otherwise, you may receive the installer image via e-mail or you can download it from the genua customer portal.

Verifying the Software Integrity

To make sure that the cognitix Threat Defender software image is intact and was issued by genua, you can verify the installation image and update files using checksums.

On the cognitix Threat Defender page of the genua customer portal access the Checksums section. The SHA-256 checksums are listed by release version.

To verify the integrity of your software, generate a local checksum using a suitable tool. Under Linux, for example, you can use the following command:

sha256sum /path/to/file

Compare the local checksum to the checksum on the genua customer portal. If it is identical, the downloaded file is intact and authentic.

Creating a USB Installer Drive


If you purchased Threat Defender with a genua hardware appliance, you also received a USB installer drive and can skip the following steps.

If you downloaded the installation image or received it via e-mail, you need to write it to a USB flash drive (4GB or larger).


Any data stored on the USB flash drive will be deleted.

There are various tools for different operating systems for creating a bootable USB flash drive, such as Etcher for Microsoft Windows, Apple macOS, and Linux. See the documentation of your selected tool on how to use it to write the image file to the USB flash drive.

Under Linux, you can also manually copy the image to the USB flash drive as follows:

  1. Make sure that the USB drive is unmounted and you know the name of the device. In this example, the USB drive is /dev/sdb.

  2. Access the command line interface and run the following command:

    sudo cp cgntx_installer_latest.img /dev/sdb && sync

    Alternatively, you can also use:

    sudo dd if=cgntx_installer_latest.img of=/dev/sdb bs=1M && sync

    Remember to replace cgntx_installer_latest.img with the actual file name of your installation file.
