The question of stability of the Higgs potential in the Standard Model is revisited employing advanced theoretical precision and recent experimental results. We show that the top mass and strong coupling constants are key observables in order to reach or refute absolute stability. We highlight new physics scenarios that lead to a decisive stabilisation of the Higgs sector. These proceedings summarise findings first reported in G. Hiller et al., Phys. Rev. D 106, 115004 (2022); Phys. Rev. D 110, 115017 (2024).
