Released in Beta in the last quarter of 2013, the Custom Virtual Appliance builder allows companies to generate custom versions of the ThousandEyes Virtual Appliance, for use as a Enterprise Agent. Extremely useful for widescale Enterprise Agent deployment, or deployment into client sites, the Custom Virtual Appliance allows organizations to pre-fill the account token used by the agent to communicate with ThousandEyes, as well as proxy and advanced access settings, including SSH keys.
