  The features of the NA62 experiment at the CERN SPS (high intensity setup,
trigger system flexibility, high frequency tracking of beam particles,
redundant particle identification, and high-efficiency photon vetoes) make NA62
particularly suitable to search for long-lived, weakly coupled particles within
Beyond the Standard Model (BSM) physics, using kaon and pion decays as well as
operating the experiment in dump mode. The NA62 sensitivity for searches of
Dark Photons, Heavy Neutral Leptons and Axion-Like Particles are presented,
together with prospects for future data taking at the NA62 experiment.
