Beyond-the-Standard-Model interactions of neutrinos among themselves — {\it secret interactions} — in the supernova core may prevent the shock revival, halting the supernova explosion. Besides, if supernova neutrinos en route to Earth undergo secret interactions with relic neutrinos, the neutrino burst reaching Earth may be down-scattered in energy, falling below the detection threshold. We probe secret neutrino interactions through supernova neutrinos and apply our findings to the supernova SN 1987A. We place the most stringent bounds on secret interactions occurring through a new mediator with mass between 10 MeV and 15 GeV.
