The internet is a critical resource for economic growth, education, and free expression — requiring stable infrastructure. Cyber threats disproportionately impact underserved communities, small businesses, and nonprofits that lack the resources for strong cybersecurity. Quad9 exists to change that. Quad9 is a nonprofit, global cybersecurity solution that provides free, privacy-first DNS security to individuals, businesses, and governments worldwide. By blocking only sites that present a danger to the end user, their equipment, or the network — and protecting against malicious websites before harm occurs — Quad9 protects vulnerable populations by preventing cybercrime and safeguarding digital infrastructure. Cybercrime disproportionately affects low-income users, activists, journalists, and emerging markets that lack cybersecurity resources. Quad9 provides the same level of protection to everyone, everywhere — at no cost. Unlike commercial providers, Quad9 does not collect or sell personal data. We exist solely to serve the public good — not to profit from the people we protect. With 260+ locations in 115 countries, Quad9 blocks an average of 670M+ threats daily, protecting millions of people worldwide. The infrastructure is already built — your support expands it. A simple DNS configuration provides instant cybersecurity for entire communities at zero cost to the end user — with long-term support and service continuity backed by a mission-driven, non-commercial organization. Fund cybersecurity as a public good — Support a solution that protects millions of people at scale, with no licensing costs and no commercial agenda. Sponsor global security initiatives — Expand Quad9’s reach to vulnerable communities that commercial providers leave behind. Advocate for privacy-first cybersecurity — Promote digital security as a core philanthropic priority in your organization and your network.
