DNS Rebinding protection is integrated into most routers nowadays. Cryptojacking protection is also just a simple combination of blocklist as far as I know. So Quad9 Threat Intelligence will probably block most of the cryptomining websites too. Still I think that NextDNS with oisd blocklist provides similar protection compared to Quad9. NextDNS development seems to be very slow tho, and also the support is pretty much non-existent. So I am not sure how well maintained their built in blocklists will be in the future. Might be a reason to switch DNS providers…
Not a chance . Nextdns is better at protecting privacy as it blocks ads and trackers. But Quad9 has far better and vast threat intelligence from leading cybersecurity companies, finance companies, Health companies and also law enforcement agencies. Nextdns uses open source free sources only, that too 35% of them are outdated and not updated any more. That goes for other protection features apart from threat intelligence feeds that uses blocklists too.
AI and NRD are the only good things.
Quad9 though doesn't have dns rebinding protection in built. Nextdns has it but for only one kind of dns rebinding attack. There are several forms of dns rebinding attacks present, and Nextdns has protection against only one kind. So does others like ControlD. But I guess some is better than nothing. Quad9 also has AI threat feeds from Bfore.ai that predicts future malicious domains that will come into existence.
No matter what extra blocklists one adds from the privacy settings in Nextdns,it cannot come close to Quad9. Although, if Nextdns in future at all does start importing threat intel from premium sources, only then it might stand a chance. But that's a big IF. Because, since past quite a few months, Nextdns devs and other team members have been dormant like a volcano. Not responding to requests or making any developments. It won't be surprising if they give up and shut down Nextdns for good.
