What is DNS Filtering?
DNS filtering, also known as Domain Name System filtering, is a crucial network security measure that protects your organization by blocking access to malicious websites and controlling access to inappropriate or unwanted content. By filtering DNS requests, this technology prevents connections to known harmful domains before any data is exchanged, providing a powerful first line of defense against various cyber threats.
How DNS Filtering Works
When a user attempts to access a website, their device sends a DNS request to translate the domain name (like example.com) into an IP address that computers can understand. DNS filtering intercepts this request and checks the requested domain against comprehensive databases of known threats and categorized content. Based on your organization's policies, the DNS filter either allows the connection to proceed or blocks it, preventing access to potentially harmful or inappropriate websites.
This process happens in milliseconds, creating a seamless browsing experience for legitimate websites while effectively blocking threats before they can reach your network or devices.
