This article reviews the allowlisting guidelines for connecting to cloud licensing, accessing nTop web resources, and receiving important email communications. nTop is a standalone application that operates locally on your desktop. However, we connect to cloud services for license authentication and account management. Some organizations may require configuring additional proxy settings.
