Quad9 is a global public recursive DNS resolver that aims to protect users from malware and phishing. Quad9 is operated by the Quad9 Foundation, a Swiss public-benefit, not-for-profit foundation with the purpose of improving the privacy and cybersecurity of Internet users, headquartered in Zürich.

== Security and privacy == Several independent evaluations have found Quad9 to be the most effective (97%) at blocking malware and phishing domains. As of June, 2021, Quad9 was blocking more than 100 million malware infections and phishing attacks per day. Quad9's malware filtering is a user-selectable option. The domains which are filtered are not determined by Quad9, but instead supplied to Quad9 by a variety of independent threat-intelligence analysts, using different methodologies. Quad9 uses a reputation-scoring system to aggregate these sources, and removes "false positive" domains from the filter list, but does not itself add domains to the filter list.
