Disclosed are systems and methods for repairing vulnerabilities of smart devices connected to a data network. An example method includes accessing, by a hardware processor, a smart device communicatively coupled to a data network, accessing a configuration of the smart device, the configuration containing settings of the smart device, comparing each of the settings of the smart device with settings of known vulnerabilities from a database of vulnerabilities to identify a network vulnerability of the smart device that can be exploited, retrieving one or more setting correcting the network vulnerability from the database, determining a repair action for repairing the at least one network vulnerability, the repair action comprising the one or more settings and transmitting, by the processor, instructions to the smart device to perform the repair action.
