Quad9 Information

Quad9 is a free service that replaces your default ISP or enterprise Domain Name Server (DNS) configuration. When your computer performs any Internet transaction that uses the DNS (and most transactions do), Quad9 blocks lookups of malicious hostnames from an up-to-the-minute list of threats. This blocking action protects your home or business network, mobile device, or IoT systems against a wide range of threats such as malware, phishing, spyware, and botnets. It can improve performance and greatly enhance privacy. Quad9 Foundation is a Swiss-based organization whose mission is to provide a safer and more robust Internet for everyone. Quad9 is a not-for-profit organization whose operational budget comes entirely from sponsorships and donations.
