  General Composite Higgs models provide an elegant solution to the hierarchy
problem present in the Standard Model and give an alternative pattern leading
to the mechanism of electroweak (EW) symmetry breaking. We present an analysis
of a realistic realization of this general idea, namely the 4DCHM, analysing
the Higgs production and decay modes, fitting them to the latest LHC showing
the compatibility with the results of the CERN machine. We then present the
prospects of a future electron positron collider of testing this model against
the expected experimental accuracies in the various Higgs decay channels
accessible herein.
