  SND@LHC is an approved experiment equipped to detect scattering of neutrinos
produced in the far-forward direction at the LHC, and aimed to measure their
properties. In addition, the detector has a potential to search for new feebly
interacting particles (FIPs) that may be produced in proton-proton collisions.
In this paper, we discuss FIPs signatures at SND@LHC considering two classes of
particles: stable FIPs that may be detected via their scattering, and unstable
FIPs that decay inside the detector. We estimate the sensitivity of SND@LHC to
probe scattering of leptophobic dark matter, and to detect decays of neutrino,
scalar, and vector portal particles. Finally, we also compare and qualitatively
analyze the potential of SND@LHC and FASER/FASER{\nu} experiments for these
searches.
