  Quantum networks consist of various quantum technologies, spread across vast
distances, and involve various users at the same time. Certifying the
functioning and efficiency of the individual components is a task that is well
studied and widely used. However, the power of quantum networks can only be
realized by integrating all the required quantum technologies and platforms
across a large number of users. In this work, we demonstrate how to certify the
distillable entanglement available in multipartite states produced by quantum
networks, without relying on the physical realization of its constituent
components. We do so by using the paradigm of device independence.
