Sounds too good to be true, but if it works there is definitely a need for this type of device.
The difference is these other products are already in the market.
I saw that a while back and was rather dubious, not helped by the lack of technical detail. If you want a network security device like this you'd be better off getting a Fingbox (not to be confused with a F'ingBox, which runs Windows 10), which actually does what it says on the cover, and is continuously updated by the devs with new features and capabilities.
+1 for fingbox. I run fing on an old tablet at the moment, and fingbox will probably happen at home soon.
Here's another one: Dojo by Bullguard.
My thought is that very rarely one can find something truly unique or new on Kickstarter. Most of times it is something already available commercially, or badly re-badged Chinese products.
There are innovative ideas but these are probably in the large minority.
