The Domain Name System (DNS) is central to the operation of modern networks, translating readable domain names into machine-usable addresses to connect users to internet destinations. DNS makes navigating to a website, sending an email, and more possible without memorizing massive amounts of numbers. As with many Internet protocols, DNS was not built to withstand abuse from bad actors’ intent on causing harm. Today’s businesses need secure, private, manageable, and visible control over internet traffic, but the public DNS system was not designed with security in mind and many DNS exploits and vulnerabilities now exist.

By using a protective DNS service like Webroot® DNS Protection, organizations control their networks and maintain the security, privacy, and visibility they need to protect IT infrastructure and users, even those working remotely. “Protective DNS” (PDNS) analyzes DNS queries and takes action to mitigate threats. This is a key defense because cyber threat actors use tricks like slightly misspelled fake websites, phishing emails with links to malicious websites, and other approaches that take advantage of human error.

The PDNS primary aim is to create a highly secure, private, resilient, and manageable connection to the internet. Automated filtering, like Webroot BrightCloud®, uses Internet Threat Intelligence to automatically block requests to undesirable, dangerous or malicious internet domains. The PDNS also checks both the domain name queries and the returned IP addresses against threat intelligence, and then prevents connections to known or suspected malicious sites. This is a key component in keeping any organization safe from ransomware, data theft, and other unwanted attacks.

This filtering alone stops most internet threats before they can infect networks or endpoints. It helps organizations achieve the management control over their DNS connection and is recommended by the NSA and CISA to strengthen Cyber Defense.
