You secure your source via your license. And a lawyer named Saul.

Really though, most enterprises aren't interested in stealing your source. If you have features they want to modify, they'll probably negotiate a source-code license with you (think: "I get to buy a beach house if this deal goes through")

I overlooked the license that would be created for hosting the source internally. That seems like a good route. I also agree that most enterprise clients wouldn't be interested in stealing the source.

It may just be a legal issue, along with a manual process of checking out the code and installing it on a VM they setup.
