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).

ReceptionRating · Positive reviews · Number of ratings

CleanBrowsing.org DNS holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: CleanBrowsing.org DNS has 329 ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 38% of CleanBrowsing.org DNS's written reviews are positive against 70% of Secure DNS & Firewall's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CleanBrowsing.org DNS ships an update every 3 weeks, Secure DNS & Firewall every 6 weeks. The most recent releases landed on September 3, 2026 and September 21, 2026 respectively.
