Quad9 DNS tool

There is a new free tool dubbed Quad9 now available to help protect businesses and users from internet threats.

Quad9 is a Domain Name Service (DNS) developed by IBM Security, Packet Clearing House (PCH) and The Global Cyber Alliance (GCA) to help protect users from accessing malicious websites known to infect systems with malware, conduct fraud or steal personal data, Help Net Security reports

The new Quad9 Domain Name System (DNS) service helps protect users from accessing millions of malicious internet sites known to steal personal information, infect users with ransomware and malware, or conduct fraudulent activity.

How does it work? Businesses and users can take advantage of Quad9’s security and privacy features by reconfiguring their devices to use 9.9.9.9 as their DNS server. Once configured, a user clicks on any website link  or types in URL to website into a web browser. The Quad9 service automatically checks the site against IBM X-Force’s threat intelligence database of over 40 billion analyzed web pages/images and other threat feeds from multiple threat intelligence partners. Malicious or known bad sites would then be blocked by Quad9 service.
