What is a DNS firewall?

A DNS Firewall is a network security solution that prevents Internet users and systems from connecting to known malicious Internet locations, keeping your DNS infrastructure online no matter what attacks are fired at your servers.

DNS Firewalls can also provide insights on threats, and stays current with the evolving threat landscape through an automated threat intelligence feed.

DNS Firewall makes running reliable DNS easy by protecting and accelerating any organization’s DNS infrastructure. With DNS Firewall enabled, DNS queries for your nameservers get sent to the nearest data center where the legitimacy of the requests are checked and malicious traffic is blocked. If the proper DNS response is available in the cache, it will return the response to the visitor. If the DNS response is not available in cache, it will query the provider's nameservers in the background to fetch the DNS response and send it back to the visitor.

​Onboarding DNS Firewall is easy, with a simple change of your nameservers’ IP addresses, your DNS infrastructure can be protected in as little as 5 minutes.
