    - Arc licenses
      Before you can deploy and use Arc, you will need to buy a license. How Arc licenses are installed will depend on the existing installation that you have. Arc and Arc Embedded require separate licenses.
    - Install a license in Guardian or CMC
      Before you can use Arc you must install the applicable license.
    - Import Arc through the update service in Guardian or CMC
      Before you can deploy Arc, you must import it first. There a two methods you can use to do this, one method is through the Nozomi Networks Update Service. The alternative method is through a manual contents upload.

Dependencies

To enable all the functions of Arc, you need to have certain items installed on the host machine.

Table 1. Linux dependencies
Traffic monitoring	Not needed
Asset details	dmidecode

During Automatic deployment, dependencies are also installed. To install the dependencies manually, download them and install them individually. Alternatively, you can use a mobile device management (MDM) tool to install them across the managed network.
