We introduce a dark neutrino sector which respects a hidden $U(1)^\prime$ gauge symmetry, subsequently broken by the vacuum expectation value of a dark scalar. Generically, this hidden sector communicates with the SM only via the three renormalizable portals, namely neutrino, vector and scalar mixing. We highlight the fact that in this unified picture the phenomenology can be significantly different from that of each individual portal taken separately. Several bounds become much weaker or can be avoided altogether. Novel signatures arise in heavy neutrino, dark photon and dark scalar searches, typically characterised by multi-leptons plus missing energy and displaced vertices. A minimal extension, possibly motivated by anomaly cancellations, can accommodate a dark matter candidate, strongly connected to the neutrino sector.
