The most secure IOT home appliances on Earth?

While listening to a recent episode of Security Now, I learned about a company in New Zealand that has
perhaps the best IOT security ever created for their home appliances to include ovens, dishwashers, refrigerators etc.

See Security Now Show Notes page 2: https://www.grc.com/sn/sn-1020-notes.pdf

While the appliances are sold in the United States, they are not cheap.

The description of the security that they alleged to have in their appliances is just about everything that anyone in the security industry could ask for.
