Likely not. If you are the kind of organization that installs this kind of hardware, you aren’t the kind of organization that permits users to configure their own machines in any substantial way, much less to work around the monitoring you worked so hard to establish.<p>Likewise, if you are that kind of organization, how hard would it be to set up the network such that only traffic from the MiTM hardware is allowed to go through the network? Is there any reason to permit local machines to establish connections outside the network for any reason?
