Quad9’s DNS blocking service has recently been part of an independent test done to compare various DNS-based blocking systems.

The health care sector is on the front lines of the fight against the COVID-19 pandemic, and protecting their networks is an important part of our need for increased cybersecurity right now.

Quad9’s free, open recursive DNS service blocks hosts, which contain malware, phishing, botnets, spyware, and a variety of other risks that try to defraud end-users, or harm their computers or networks. Millions of users around the world use Quad9’s free DNS recursive resolvers (9.9.9.9/149.112.112.112) to map hostnames to IP addresses as part of almost every Internet transaction.

As physical offices and schools shut down worldwide, people are rapidly relying more and more on a home-based telecommuting environment. Security protections once provided by enterprise or school network administrators must be available to the home network.

In times such as these, bad cyber-actors will also emerge. We’ve been alerted to a rise in phishing, malware, and ransomware attacks from a number of our Threat Intelligence Providers and public sources such as; EFF, IBM, and DomainTools. Rest assured, we are working to protect our global user base and add these malicious sites into our Block List as quickly as possible.

The Quad9 project treats user privacy as a first-order priority along with performance and security. Part of the concept of privacy is keeping others from seeing what DNS requests you are sending.

Some of you may have seen announcements of Quad9’s participation in the industry-wide “DNS Flag Day” event, slated for February 1, 2019.

DoH is a secure DNS protocol that is getting a lot of traction lately. Mozilla announced support for it in their Firefox browser and Google recently announced support for developers and Alphabet through Jigsaw released the Intra app for Android.

You might have seen the news that Google released a new feature called Private DNS mode in Android 9 Pie.
