I've deployed Git on a server in our DMZ for testing. So, it's possibly accessible from external IPs, but in reality we're using it via a VPN connection, so it's mostly internal. I haven't locked down the security yet. My idea is to create an internal git server that is freely accessible when connected via VPN or secure HTTPS (when not on VPN). From what I've read, the self-hosted GitHub is far beyond our budget. We already have VM servers available. It's just a matter of choosing an appropriate self-hosted solution (e.g. WebGitNet, etc) vs. a more established and polished GitHub solution.
