I had this problem at another company, but that was something like
ten years ago.  I think I solved it by either renaming nc.exe to
something else, compiling my own Netcat, or using Socat, but I don't
remember which approach actually worked.

And of course, depending on the company and the IT department, you
may want to consider whether using the program in spite of their
efforts to prevent you from doing so is worth the risk of
termination.
