How prepared is the cloud?

Hello Sparks,

how prepared is the cloud against hackers? We are not sony but the IoT will get into every household in the long run, from door locks to energy systems. We have already projects like Wifi Power Outlet, Nest-alike, e-paper wifi keypad and more. Sooner or later the Spark might end up in a mass produced item.

I am not a security expert so how vulnerable is this service?
