FastX 3


Due to the highly sensitive nature of the data contained in Stronghold, CIS has taken measures to restrict the ability to accidentally or intentionally move data out of the environment. Direct SSH access is not enabled for end users, as there is no way to restrict copying and pasting the contents of a file from an SSH session.
FastX 3 allows users to copy and paste from their local clipboard into their Stronghold session, but not in the opposite direction.
Users can connect to Stronghold via FastX3 from either a web browser, or a FastX3 client that can be downloaded from Brown Software Catalog.

Connecting via a FastX3 Client
