Long-lived particles (LLPs) are predicted in several beyond the Standard Model theories. Their signals can be tested at the LHC main detectors (such as ATLAS or CMS), current and proposed far detectors (such as FASER or MATHUSLA), as well as other experimental facilities. I will broadly comment on the motivations and the need to perform LLP searches, wrapping current LHC challenges and gaps. I will detail phenomenological prospects to search for BSM physics with non-standard displaced signatures, focusing on models predicting long-lived heavy neutral fermions.
