[QUOTE="SohanRay, post: 980848, member: 94632"] I have seen many test results over the Internet. Sometimes NextDns does well, sometimes CleanBrowsing does well. But Quad9 always does well no matter which test results you look at. Now you may say do your own testing and see. But the test results depends a lot on the sources you use to gather the malicious domains. What normal users can gather would be from public lists. Now NextDns uses public lists, so its more likely to shine. But lists from say cybersecurity firms would never be available to general people, if you had tested on their lists NextDns most probably would have done bad. Public lists have a lot of false positives. You'll find opendns not blocking most domains mentioned in Openphish (public list) which they themselves back and is a part of their own company initiative. Why? Its because they don't trust their own initiated source completely. Even Quad9 doesn't block a lot of domains from Openphish. Same reason. But if you see NextDns, it would probably block almost all of it if not all. So the thing is all NextDns has are those free public lists in their arsenal. And these lists are literally accessible by anyone. But the premium private ones are the ones accessible by only authorized entities. So all services using such premium private services, can easily use all or any of those public lists. Its pretty obvious. So now which one is bound to perform better? The answer is obvious right... Quad9 uses threat intel from so many leading cybersecurity companies on near real time basis. And also any vetted domains from public lists. [/QUOTE]
