What is a DNS Firewall?

A DNS Firewall firewall is a network security solution that prevents network users and systems from connecting to known malicious Internet locations. DNS Firewall works by employing DNS Response Policy Zones (RPZs) and actionable threat intelligence to prevent data exfiltration.

DNS Firewalls can also provide insights on threats, helps isolate infected devices for remediation, and stays current with the evolving threat landscape through an automated threat intelligence feed.
