Quad9 is a free, recursive, anycast DNS platform designed to boost your online security, speed, and privacy effortlessly.
When you type a website address or click a link, Quad9 checks it against a huge list of known malicious domains gathered from over 20 threat intelligence partners. These partners analyze sites using advanced techniques like malware scanning, network behavior tracking, and even visual and text recognition to spot dangerous content. If a site is flagged as malicious, Quad9 blocks the connection, keeping your computers and devices safe from malware and phishing attacks.
