They all do it the same way. The launch vehicle provider is responsible for deploying the customer's payload to a given orbit. They work side by side with the customer at the range and in mission control. But they are on the hook to deliver the payload to orbit.
The range operator is the principle gatekeeper. You may have noticed that the final delays on the first Falcon 9 launch were related to preparing data for the range safety officer. You don't need NASA or the air force to get to orbit, Telecomm and sattelite tv firms get their satellites to orbit. They work with the ranges for approvals and safety.
