A black hole holographic model is used to mimic the behavior of the quark gluon plasma at finite temperature and density. This model reproduces lattice data at $\mu_{\mathrm{B}}=0$ and displays critical behavior at large densities. High-order baryon susceptibilities are used to extract freeze-out points by comparing those susceptibilities with the corresponding net-proton distribution measured by STAR. Possible experimental signatures of the critical end point are discussed.
