The Unitarity Triangle (UT) analysis can be used to constrain the parameter space in possible new physics (NP) scenarios. We present here an update of the UT analysis beyond the Standard Model (SM) by the UTfit collaboration. Assuming NP, all of the available experimental and theoretical information on $\Delta F=2$ processes is combined using a model-independent parametrisation. We determine the allowed NP contributions in the kaon, $D$, $B_d$, and $B_s$ sectors and, in various NP scenarios, we translate them into bounds for the NP scale as a function of NP couplings.
