In the present, there are basically two challenges that are inhibiting IoT growth. One is the precious bandwidth resource, which is depleting with each passing day. Another is the security risk posed by automated functioning of IoT devices. An internet of things service provider should be good enough in fulfilling both these requirements for it to be considered a worthy candidate.
For a layman or someone new to IoT, it is not an easy task to pinpoint the most important features. Lack of knowledge can be the biggest adversary when it comes to achieving success. If you fail on the security front, no matter what else you are doing, your IoT empire would come crashing down.
