This Glowing Rock Wants to Monitor Your Internet of Things.

There is a smooth, dark brown stone sitting in front of me on the table with a bright circle pulsing on its face a signal, apparently, about the security status of Yossi Atias is fictional Internet-connected home.
Atias is the CEO and cofounder of an Israeli startup called Dojo-Labs, one of numerous companies trying to secure the so-called Internet of things. The stone is part of its first security product, Dojo; it gets alerts via low-energy Bluetooth from a white, rectangular device that plugs into your Wi-Fi router and monitors the network activity of Internet-connected home gadgets like smart lights, TV sets, and alarm systems.
When something out of the ordinary happens for example, a stranger tries to remotely disable your home alarm system, which Atias demonstrates by hacking into an alarm set up at his companys office in Israel Dojo reacts automatically to stop it and sends you a message through its smartphone app to let you know what’s going on. The glowing ring on the stone, meanwhile, would change from white (an indication that everything’s fine) to orange.
