The sensitivities to the anomalous quartic gauge boson coupling gamma gamma gamma Z are estimated via gamma Z production with intact protons in the forward region at the LHC. Proton tagging proves to be a powerful tool to suppress the background, which allows consideration of the hadronic decays of the Z boson in addition to the leptonic ones. We discuss the discovery potential for an integrated luminosity of 300 fb(-1) and 3000 fb(-1). The sensitivity we obtain at 300 fb(-1) goes beyond the one expected from LHC bounds on the Z -> gamma gamma gamma decay by about three orders of magnitude. The gamma Z channel provides important discriminatory information with respect to the exclusive gamma gamma channel, as many particles beyond the Standard Model (such as a radion or Kaluza Klein gravitons) predict a signal in the latter but not the former.
