As part of the DNS system, it checks every accessed IP address to determine whether it has been classified as dangerous. Depending on the check results, the webpage is either displayed or not.How does the DNS firewall work?A DNS firewall filters the traffic that moves through DNS endpoint services. Each DNS request is screened against a denylist, including various dangerous IP addresses, hosts, or websites. The web request is denied if an address or host is found on the denylist.DNS firewalls need to be continuously updated with the latest DNS threat data for this solution to be effective. As malicious domains are constantly taken down and set up, a DNS firewall must keep up with the changes by updating threat intelligence.Some DNS firewalls are expanded with AI capabilities capable of learning and recognizing malicious websites in real time. The bottom line is that a DNS firewall is as secure as an up-to-date or smart denylist is.Benefits of DNS firewallTraditional firewalls use complex and proprietary technologies yet can fail at detecting various DNS-based threats. Which is why DNS firewalls are an important subset of DNS security. Here are the principal benefits that they're bringing to organizations.Highly customizableMalicious URL redirects can serve as educational materials by informing users what they have just avoided.
