An overview of 1E Client features and modules. The 1E Client provides client functionality for Shopping, WakeUp, Nomad, and Tachyon.

The 1E Client

In response to customer demand to reduce the number of agents required, 1E have unified the client functionality for Nomad, PXE Everywhere, Shopping, WakeUp, and Tachyon into a single 1E Client.

On Windows devices, 1E Client provides the following:

  • Tachyon client features - see below
  • User surveys and notifications, and notification area icon called 1E Client UI. This is used by Tachyon Experience to enable User Sentiment and Info Surveys to be presented to end-users.
  • Tachyon Telemetry. This information enables 1E to improve its product capabilities and features. It can be configured during Tachyon Setup and information on the data that is sent to 1E is provided in the Tachyon platform documentation.
  • Nomad client module - supports content distribution for Configuration Manager and Tachyon
  • PXE Everywhere client module - also known as PXE Everywhere Agent - which allows computers to automatically boot up into Windows PE, which then allows a Windows Operating System to be installed
  • Shopping client module - supports access to a self-service software portal (which integrates with Configuration Manager) and includes the Windows Servicing Assistant (WSA) to support OS deployment
  • WakeUp client module - integrates with Configuration Manager, NightWatchman and/or Nomad.

On non-Windows devices, 1E Client provides only Tachyon client features.

Tachyon client features:

  • Real-time response to instructions, which supports the retrieval of information using questions, and running actions
  • Tags (freeform and device/coverage)
  • Criticality and Location

  • Inventory, including process usage, to support:
    • the Tachyon Activity Record feature

  • Performance metrics features to support the Experience application #
  • Policy feature to support consumer applications: Guaranteed State ##, Experience #, and Nomad #

    • the Patch Success application #
    • command and script execution
    • content distribution
    • device criticality

# not supported on non-Windows, ## partially supported on non-Windows

Many features and modules are optionally enabled and configured. The 1E Client can also be extended to support additional features and client modules.

1E Client does not include modules for 1E NightWatchman Agent, which is available as a separate agent. However, NightWatchman Management Center optionally integrates with Tachyon to provide online status of its clients.

On Windows devices, the 1E Client is installed as a Windows service, with a small footprint, with some client modules having their own service if enabled. On non-Windows devices, the 1E Client is installed as a background daemon, also referred to as a service on macOS.

1E Client versions

The picture below shows the evolution of the 1E Client from a combination of other 1E Agents.

On non-Windows devices, 1E Client provides only Tachyon client features.


The 1E Client Deployment Assistant (CDA) can be used with Microsoft System Center Configuration Manager to deploy 1E Client to Windows computers, and also 1E NightWatchman Agent.

1E Client may be deployed independently using alternative software distribution methods.
