INTERNET SECURITY & PRIVACY IN FOUR 
SIMPLE STEPS

Put your DNS to work today.

Every website has a numerical address – known as an IP (Internet Protocol) address. DNS (Domain Name Server)  is what translates these numerical IP addresses into readable domain names we all know and remember. If your DNS settings are not working correctly, or you’re using the default setting, you may be at risk for cybercrime and performance issues.

What is DNS?

How Quad9 Works

Quad9 routes your DNS queries through a secure network of servers around the globe. The system uses threat intelligence from more than a dozen of the industry’s leading cyber security companies, to give a real-time perspective on what websites are safe, and what sites are known to include malware or other threats. If the system detects that the site you want to reach is known to be infected, you’ll automatically be blocked from entry – keeping your data and computer safe.
