We love Circle and what it's doing to help protect kids on the internet. It may be the right solution for some. One of the drawbacks is it's use of a protocol called ARP spoofing that can severely slow down the home network. Also, it may not work with some of the routers, making it difficult to install and use. Gryphon provides a simple to use solution in a single WiFi router while also having super-fast wifi performance with 6 high powered antennas. Through the app, we made it simple to do real time control from anywhere and guide the parent using CrowdRanking.
