Does this: https://www.kickstarter.com/projects/akita/akita-instant-privacy-for-smart-h... do anything special that is not already available in linux software? Apart from a neat packaging exercise of course? The description includes: "Connected to a LAN port on your router, Akita scans your network for any unusual activity and immediately shuts it down. All-the-while letting you know an attempt was made to invade your privacy. Akita uses military-grade security protection that’s been retrofitted for the home. Then, if you run into any issues, we can remotely preserve and restore your privacy with the help of our always on-call privacy experts at Axi.us. Akita uses threat intelligence, behavioral analysis, machine learning and doesn't slow your connection at all. Importantly, it doesn't use deep packet inspection."
