Cyber threats are growing every day — targeting the devices in your home, the accounts you rely on, and the personal data you share online. Whether you’re browsing, banking, streaming, or working from home, you deserve security that works automatically, without the cost or complexity. Change one setting and get instant protection. Configure Quad9 on your router once and every device in your home is covered — phones, laptops, smart TVs, and connected devices that can’t run their own security software. Stops threats before they reach you. Quad9 checks every DNS lookup in real time against threat data from 35+ threat intelligence partners — blocking malicious sites before your device ever connects. No tracking, no ads, no collecting or selling of your data. Your DNS queries are never logged.

Quad9 ensures you can browse freely while staying secure, without big corporations profiting from your data.
