Your Agent is running properly. It will continue to run in the

You can check the agent status using the \"vanta-cli status\" command.

If you ever want to stop the agent, please use the toolbar icon or
the vanta-cli command. It will restart automatically at login.

To register this device to a new user, run \"vanta-cli register\" or click on \"Register Vanta Agent\"
on the toolbar.
