A lot of "enterprise" type situations just don't get github or similar solutions. They might have something like Visual Source Safe or no version control at all, and Windows servers setup so that the only access to them is by VPN and copying files to a Windows network share. Unfortunately it's just the way some organizations work and there isn't much you can do to change it.
