Zenon project protection from uploading

Zenon project protection from uploading

Just want to find the best way to keep my Zenon project secure.
At the moment the source files are all on a PC and downloaded to the remote project on CE hardware.
If the CE hardware is given to a client when the project is handed over, can the client upload the files (via zenon editor or copy from CE compact flash card), add another user will full access and download the project again therefore allowing them to have admin access and get into administrator pages that they should not be able to do.
If this is possible, what security can I put in place to stop this.
If the files that are downloaded to the remote CE device are complied files that can't be backwards engineered, then this will not be a problem.
Thank you
Matt
