Your people and their knowledge have real value. The code alone has limited value to anyone else, without the associated expertise. And if it does leak, normal legal protections can mitigate the damage. (For example, the threat of a copyright or trade secret lawsuit may be enough to keep competitors from using or even looking at your code without permission, depending on who they are.) On the other hand, accidental breaches do happen (whether outsourced or self-hosted), so you should probably keep your secret keys and passwords even more protected than your source repository.
