What is a DNS Firewall

One firewall security solution that can help keep malware off of your website is a DNS firewall. Domain Name System, or DNS for short, is the equivalent of the internet’s phone book. It converts domain names that are easy for humans to understand, like, into IP addresses that computers can use to talk to one another.

A DNS firewall works by filtering DNS requests. When someone tries to visit your website, the DNS firewall checks the request against a list of known malicious sites. If the request is safe, it allows the visitor to access your site. If the request is flagged as malicious, it blocks the visitor from accessing your site, preventing potential malware infections.
