Techniques are described for mediating enterprise service access for smart devices. A first message may be received at an enterprise service proxy device from a smart device via a first protocol associated with the smart device. It may be determined that the first message includes a smart device request for processing via an enterprise service located at a backend device. An enterprise service request and an associated enterprise request protocol may be determined based on the smart device request and a service adaptation description associated with the enterprise service and the first protocol. The enterprise service request may be sent to the backend device via the associated enterprise request protocol.
