DNS firewall, also known as a DNS-based threat intelligence system, is a security solution that operates at the Domain Name System (DNS) level to protect networks from various cyber threats, such as malware, ransomware, phishing, and botnets.

How it works

DNS firewall intercepts DNS requests and uses threat intelligence feeds to block requests for known malicious domains or IP addresses.


By preventing these requests from being resolved, a DNS firewall can effectively prevent communication with malicious servers and attacks from reaching the network.


Provide visibility into network traffic by logging DNS requests and responses, which can be used to identify potential threats and investigate security incidents.


A DNS firewall can effectively enhance network security by preventing access to known malicious domains and providing visibility into network traffic.
