  - Configure an Arc sensor in Guardian
    You can configure an individual Arc sensor in Guardian directly from the Sensors details page for the related sensor.
  - Configure an Arc sensor in Vantage
    You can configure an individual Arc sensor in Vantage directly from the Sensors details page for the related sensor. Arc sensors in Service mode use these settings.
  - Discovery and Smart Polling conditions
    The minimum conditions required to run Discovery and Smart Polling on Arc depend on the Arc deployment mode.
  - Local UI
    The default method to manage Arc is through the upstream Nozomi Networks product, which applies configurations to all Arc sensors in Service mode. However, it is also possible to manage Arc through a local UI for One-shot and Offline executions.

Compliance scanning

Arc is the sensor that Compliance scans run against. Compliance scans run only when they are requested from the upstream system that manages the sensor.

Configuration

Compliance scanning is enabled or disabled from the upstream system that manages this Arc sensor. This setting does not appear in Arc's own local configuration user interface (UI).

Supported platforms

Compliance scanning is supported on Windows, Linux, and macOS Arc sensors.

On-disk layout

Arc stores compliance data in a compliance folder next to the Arc executable, with benchmarks and results subfolders. This folder is preserved across a re-setup of Arc.

Licensing and availability

Compliance is a licensed feature, and the license comes from the upstream system that manages this Arc sensor. The Compliance item appears in Arc's local navigation bar only when both of these conditions are met:

A valid Compliance license has been received from the upstream system.
The Compliance feature is enabled for this sensor, from the upstream machine.

You enable the Compliance feature for a sensor from the upstream machine. For the steps, see Enable or disable Compliance on an Arc sensor.
