DNS Filtering is one of the most effective ways to improve online security and protect users from malicious threats. Every time you type a website address, your device relies on the Domain Name System (DNS) to translate that domain into an IP address. DNS Filtering adds a crucial layer of protection by controlling which DNS requests are allowed and which are blocked. This simple yet powerful mechanism can stop cyberattacks before they even reach your network or device.
What Is DNS Filtering?
At its core, DNS Filtering works by checking every DNS query against a database of known malicious, suspicious, or unwanted domains. If the requested website is safe, the query resolves normally, and you can access the site. If the domain is flagged as harmful, such as a phishing site, malware distributor, or botnet server, the request is blocked, preventing your browser from connecting.
It acts as the first line of defense. Unlike traditional firewalls or antivirus software that react after the threat reaches your system, filtering stops it at the DNS level, long before any harmful code is executed.
