Various examples for performing rule processing for device management data evaluation are described. According to some examples, one or more computing devices can receive new device data from a client device indicative of a current configuration of the client device and identify a change of a device configuration value from a past device configuration value by comparing the new device data to historic device data. The computing devices can send the new device data to a rule evaluation service to identify one or more rules associated with the device configuration value a rule action service to perform an action specified in the rules. The rule action service can determine the action to perform based on the device configuration value.
