An enterprise IoT concentrator can receive, from a first community IoT concentrator, first data corresponding to a security issue detected by at least one of a first plurality of devices located within a first physical environment, wherein the first plurality of devices are communicatively linked to one another within a first device domain that is a member of a first device community which includes the first community IoT concentrator. Responsive to receiving the first data, the enterprise IoT concentrator can process the first data to generate second data corresponding to the security issue. The second data can be configured to be processed by a second community IoT concentrator to initiate at least one device located within a second physical environment to perform a specific act that enhances security in the second physical environment. The enterprise IoT concentrator can communicate the second data to the second community IoT concentrator.
