cybersecurity tools to individuals, companies, and other organizations. Quad9 is funded by industry grants and support from other non-profit organizations in order to increase security and stability of the Internet. This service is provided at no cost.
Quad9 uses DNS-over-TLS to encrypt and protect your DNS against interception or manipulation by anyone on your local network or any other link between you and the nearest Quad9 server.
Quad9 combines more than 18 unique sources of threat intelligence. These lists include both open and commercial sources, and protect against a variety of common threats like malware, viruses, phishing hosts, botnet control hosts, and other risks that are criminal in nature. If your device tries to connect to one of these sites, Quad9 prevents the connection and warns you that there was an attempt to connect to one of these known risks. Quad9 also implements strict DNSSEC, which is a method that ensures the DNS answers given are correct. You may turn off the blocking protection and just get ‘plain’ DNS with no blocking and no DNSSEC via an app setting option. Quad9 does not filter any other content categories.
