The problem is big players do identify the issue of how vulnerable IoT devices are and will always be because there are no standards, there are no guidelines and any tom-dick-harry is manufacturing them and selling them off ebay. At the end of next year probably there will be 10-20 IoT devices running behind Cisco/Juniper/Huawei gateways/edges and people will expect these gateways to take care of the security rather the devices itself. Most of the IoT devices run Android and hence IPv6 ready so it is going to be a nightmare for not only enterprises but home users as well.
