The present work is aimed at detecting AGNs in the COSMOS field on the basis of their optical variability, using data from the SUDARE survey by the VLT Survey Telescope (VST). The effectiveness of the method against other traditional photometric approaches was already explored in De Cicco+ 2015. Here we take advantage of the long (> 3yr) observing baseline to achieve great improvement in the completeness of our sample and to make use of the structure function of our confirmed AGNs to characterize the sample.
