The techniques disclosed herein enable systems to manage remote file storage systems while bolstering information security through file encryption on download and permissions labels. To achieve this, a site owner configures permissions for a network site that stores files and that enables encryption on download. Various users with file access via the permissions may then interact with the site. When a user downloads a file from the site, they receive an encrypted copy that includes a permissions label that synchronizes with the network site permissions. When a user attempts to interact with an encrypted file the permissions label is used by the system to determine whether the user is authorized to access the file. In addition, permissions that are changed at the network site can be propagated to downloaded encrypted copies. In this way, permissions can be enforced for all site files even when copies leave the network site.
