Quad9
Non-profit threat-intelligence-filtered DNS that blocks malicious domains using 20+ threat feeds.
Quad9 is a non-profit DNS resolver that blocks known malicious domains by cross-referencing 20+ commercial and public threat-intelligence feeds in real time. It's not an ad blocker — it focuses purely on security: malware, phishing, botnet C2, and scam domains. Quad9 operates from Switzerland with a strong privacy policy (no PII logged, IP addresses not stored). It supports DoH and DoT. Because it's a non-profit, there's no monetization model — your DNS queries aren't the product.
