A method and system. One or more policies is stored. Each policy includes activities for execution on corresponding endpoints. At least one of the activities of the policies is conditioned by a condition based on one or more aggregated parameters. Each aggregated parameter depends on one or more local parameters of a corresponding group of endpoints. The local parameters are collected from the corresponding endpoints. The local parameters are aggregated into the aggregated parameters. Each aggregated parameter is distributed at least to the corresponding endpoints of each policy including any activity conditioned on the aggregated parameter. At least the corresponding policies are sent to the endpoints to cause each endpoint to apply each corresponding policy by collecting any aggregated parameters of the policy on the endpoint and executing the activities of the policy according to the corresponding aggregated parameters.
