They get shit on a lot here. Why? What do they do and how is that different from other companies that offer similar services?
What I know of them: they offer DDS brute force/spam protection for websites.
For the better part of a decade, I’ve used Cloudflare’s DNS servers, 1.1.1.1 & 1.0.0.1, mostly because they claimed it was more secure and slightly faster than say, Google’s 8.8.8.8.
What are the secure-minded folks using these days?
Cloudflare’s 1.1.1.2 blocks known malware domains, so that’s better than 1.1.1.1 unless you want nothing blocked.
If you want to block ads and trackers in addition to malware, try ControlD’s 76.76.2.2 .
Better still is to use encrypted DNS if your device supports it. I like NextDNS or ControlD for that, as DNS-Over-TLS or -HTTPS.
