What makes Quad9 different from other public DNS services is its core mission: security. When you use Quad9, it doesn't just translate domain names; it actively cross-references your query against a real-time, up-to-the-minute threat intelligence list. If the website you are trying to visit is known to host malware, phishing scams, or participate in botnet operations, Quad9 will block your device from connecting to it, stopping the threat before it has a chance to load on your computer or phone. This approach offers a first line of defense that can eliminate exposure to risks before they are even downloaded. A study has even shown that a DNS-based system like Quad9 can block approximately 33% of cybersecurity breaches.
