Recommended. The Firewalla Purple brings firewall management to the masses: It has a great GUI that makes it easy for less-technical users to see what is happening on your network and to manage devices. Firewall rules are easy to set up and content filtering policies can be toggled on and off by device or group. There are a few minor shortcomings but the feature set is still being extended. The Purple is an excellent device for managing small networks and the online activities of children. However, it is highly overpriced.
