Systems, methods, and related technologies for segmentation management are described. The segmentation management may include visualization, configuration, simulation, or a combination thereof of one or more segmentation policies. In certain aspects, a plurality of segmentation rules are accessed and one or more characteristics of a plurality of entities communicatively coupled to a network are determined. A plurality of groups may be determined based on at least one characteristic of the one or more characteristics, where each group comprises at least one entity of the plurality of entities. A first group and a second group from the plurality of groups may be selected and one or more segmentation rules associated with the first group determined. One or more segmentation rules associated with the second group may be determined. Communication properties between the first group and second group may be determined and an indication of the communication properties between the first group and the second group displayed.
