We discuss a mechanism of double protection of the Higgs potential by supersymmetry and by a global symmetry. This occurs in supersymmetric models in which the Higgs boson is a Goldstone boson of a spontaneously broken approximate global symmetry, as in little Higgs. In such models the parameters of the electroweak sector require no fine-tuning at all.
