OpenDNS FamilyShield review

OpenDNS FamilyShield is not an app, and that is its appeal. It is a free DNS service from Cisco that you set on your home router, after which every device on the network, from laptops and phones to game consoles and smart TVs, has adult content blocked. OpenDNS says it is preconfigured and needs no sign-up. Families who want to choose categories themselves can create a free OpenDNS Home account, which adds customizable filtering. The trade-off is scope. FamilyShield sets no time limits or schedules, it only filters while devices are on the home network, and a phone on mobile data is outside its reach. It works best as a base layer under Family Link, Screen Time or Microsoft Family Safety, catching devices those apps do not cover, such as a smart TV or a visitor's tablet.
