Supersymmetric models with a warped fifth spatial dimension can solve the hierarchy problem (avoiding some shortcomings of non-supersymmetric constructions) and predict a plethora of new phenomena at typical scales $\Lambda$ not far from the electroweak scale ($\Lambda\sim$ a few TeV). The low-energy effective theories of these models, valid at energies below $\Lambda$, can deviate significantly from the Minimal Supersymmetric Standard Model (MSSM) or other popular extensions of it, like the NMSSM. The resulting phenomenology is pretty unconventional, in particular electroweak breaking occurs in a non-radiative way, with $\tan\beta\simeq 1$ as a quite robust prediction, while the mass of the lightest Higgs boson can be as high as $\sim$ 700~GeV. _
