  In a model independent framework, the effects of new physics at the
electroweak scale can be parametrized in terms of an effective Lagrangian
expansion. Assuming the $SU(2)_L x U(1)_Y$ gauge symmetry is linearly realized,
the expansion at the lowest order span dimension--six operators built from the
observed Standard model (SM) particles, in addition to a light scalar doublet.
After a proper choice of the operator basis we present a global fit to all the
updated available data related to the electroweak symmetry breaking sector:
triple gauge boson vertex (TGV) collider measurements, electroweak precision
tests and Higgs searches. In this framework modifications of the interactions
of the Higgs field to the electroweak gauge bosons are related to anomalous
TGV's, and given the current experimental precision, we show that the analysis
of the latest Higgs boson data at the LHC and Tevatron gives rise to strong
bounds on TGV's that are complementary to those from direct TGV measurements.
Interestingly, we present how this correlated pattern of deviations from the SM
predictions could be different for theories based on a non--linear realization
of the $SU(2)_L x U(1)_Y$ symmetry, characteristic of for instance composite
Higgs models. Furthermore, anomalous TGV signals expected at first order in the
non--linear realization may appear only at higher orders of the linear one, and
viceversa. Their study could lead to hints on the nature of the observed boson.
