Tools and Solutions >> DNS Resolvers
Quad9 is a Swiss-based non-profit foundation founded in 2016, focused on providing secure DNS services. It blocks access to malicious websites to protect users from cyber threats. Using the DNS resolver 9.9.9.9, it ensures privacy by not collecting personal data and supports encrypted DNS protocols.
When your computer performs any Internet transaction that uses the DNS (and most transactions do), Quad9 blocks lookups of malicious host names from an up-to-the-minute list of threats. This blocking action protects your computer, mobile device, or IoT systems against a wide range of threats such as malware, phishing, spyware, and botnets, and it can improve performance in addition to guaranteeing privacy.
