Any data exchanged outside of the professional briefcase (via email or fax, for example) will not be available through Praos. It is your responsibility to store independently gathered data on your own systems.

This information is available to you when they share it and retained as part of the job history. You should request that they share documents securely via the Profesisonal Briefcase.
