Better connectivity for everyone!
I don't think I'll ever have to worry about having to use a new interface like Shodan for a while yet. At this moment, my company's network is small enough that I'm pretty sure you can find the devices that you're looking for just by walking around! Haha! But I reckon that for the bigger enterprises that this must be really quite handy to help keep the employees at work. No doubt about that!
