I will discuss phenomenological obstacles to associating the 126 GeV scalar boson discovered by the LHC with a dilaton arising from the spontaneous breakdown of conformal symmetry in strongly coupled extensions of the Standard Model.  I will explore a possible class of solutions to one of these problems - namely the existence of a gap between the scalar mass and the breaking scale of conformal symmetry, and give an explicit holographic construction that realizes it.  Interestingly, the contribution to the cosmological constant from condensates is suppressed in such models.
