  We analyze the phenomenological consequences of assuming that the 125 GeV
boson measured at the LHC coincides with one of the two CP-even Higgs bosons of
an effective Minimal Supersymmetric extension of the Standard Model at the
electroweak scale. We consider the two ensuing scenarios and discuss critically
the role of the various experimental data (mainly obtained at colliders and at
B-factories) which provide actual or potential constraints to supersymmetric
properties. Within these scenarios, properties of neutralinos as dark matter
particles are analyzed from the point of view of their cosmological abundance
and rates for direct and indirect detections.
