What is DNS Firewall and How Traffic Filtering Works. VPN vs Firewall
DNS Firewall is a network security solution that intercepts DNS resolution for known-malicious websites and protects your devices from malware infection. In simple terms, it prevents you from connecting to known malicious Internet locations and ensures that your private data remains protected.
To top it off, DNS Firewall also allows to block sites that contain annoying pop-up windows and undesirable content (like gaming, gambling, adult sites). Keep reading for more information about VPN vs Firewall!


How DNS Firewall works
The first thing to figure out when exploring the VPN vs Firewall question, we should note that DNS-based malware is one of the most dangerous cyber threats that are used to steal your online identity. According to a global 2019 DNS Security survey, 91% of malware use DNS services to build their cyber attacks and 82% of survey respondents had been targeted by a DNS attack during the last year. DNS Firewall, in turn, has been created to safeguard our users from such attacks.
When the technology intercepts malicious DNS response, it directs a website with this response to a walled garden and makes such a malicious network unreachable for your device. The work of DNS Firewall can also be compared with a custom house. The customs officer is responsible for preventing the importation of illegal and/or dangerous goods into the country, and DNS Firewall is responsible for preventing the importation of malware to your device.
