The Unified Model for Active Galactic Nuclei (AGN) cannot explain some features of low luminous AGN. In this work, we present a multi-epoch analysis of the X-ray variability of the Low-Luminosity AGN NGC1052 to understand its true nature. We use data from XMM-Newton, Suzaku and NuSTAR and also include ancillary data from Chandra to decontaminate from circumnuclear emission. We test two different models accounting for two scenarios: a uniform absorber and a partial-covering absorber. Among the results, we find variations in both flux and spectral shape. We find variations in the photon index of the power-law like emission from the intrinsic continuum and on the absorption in the line of sight. We also find that the partial-covering scenario can explain the data better as it is ~200 times more probable than the uniform absorber.
