  We present a class of composite Higgs models arising from a warped extra
dimension that can satisfy all the electroweak precision tests in a significant
portion of their parameter space. A custodial symmetry plays a crucial role in
keeping the largest corrections to the electroweak observables below their
experimental limits. In these models the heaviness of the top quark is not only
essential to trigger the electroweak symmetry breaking, but it also implies
that the lowest top resonance and its custodial partners, the custodians, are
significantly lighter than the other resonances. These custodians are the
trademark of these scenarios. They are exotic colored fermions of
electromagnetic charges 5/3, 2/3 and -1/3, with masses predicted roughly in the
range 500-1500 GeV. We discuss their production and detection at the LHC.
