CleanBrowsing is a DNS-based content filtering service that offers a safe way to browse the web without surprises. It intercepts domain requests and filter sites that should be blocked, based on your requirements. Our free family filter, for example, blocks adult content, while still allowing Google, Youtube, Bing, DuckDuckGo and the rest of the web to load safely. Our free filters are comprised of three predefined filters for global consumption (Security, Adult, and Family). The Family filter blocks adult / obscene content and applies Safe Search filters to Google, Bing, Yandex, etc. The security filter, however, only focuses on restricting access to malicious activity. Our custom filters give you full control on what should be blocked. You can pick from 14 predefined filters (Adult, Gaming, Gambling, Torrents, Weapons, Social Network, etc), but also make your own rules and block/allow any domains you wish. Custom block pages can also be created on the Pro plans and all the plans allow for network visibility (see which sites are being visited from your network).
