What does the challenge of security mean for potential IoT customers?
Tantzen: It's what's you're connecting into that has the problem. The car is not secure, the factory is not secure. And the reason for that is when they built these real-time control networks, many of them were using 30-year-old technology that is still in place today. You'll see it in the car, you'll see it in a factory. Those systems have low-data paths, low-data rates, but they're also not secure. There's no security built in to those capabilities.
If you go into a factory, I think people don't know this, but all the robot automation cells and the control that works and all that, they're all separate from the IT network. And they're not secure, but they're separate. But as you want to enable IoT, and you want to actually connect to these machines and get data for predictive maintenance and drive these billions and billions of dollars, that doesn't work anymore. So we now have to connect these legacy OT environments to the rest of the enterprise to get the value from IoT. And that requires, not just security on the IoT connection, but to now make those OT legacy environments secure.
