Yes, but if you sign the executable with an acceptable certificate (the company’s cert or some other trusted CA), you can install an arbitrary executable usually. Docker would typically be blacklisted, however. In most corporate IT environments, it’s much easier to get a small, focused executable white listed or code signed than to get something with such a huge attack area as docker approved for regular, non-technical users.
