DNSFilter was born of co-founder Ken Carnesi's dissatisfaction with the lack of solutions for blocking access to malicious sites. DNSFilter was designed to be effective and easy to deploy: it takes just a few minutes to be protected, where conventional solutions sometimes take several days to set up. Launched in 2015 and honored during Cybersecurity Awareness Month, the Washington-based company has won over more than 43,000 organizations, from start-ups to Fortune 500 groups, and now has more than 35 million users protected on a daily basis.

In concrete terms, DNSFilter sorts connections at web address level: if a site hidden behind a link is booby-trapped, it is blocked even before the connection is made. Today, the platform handles 180 billion queries a day (180 times more than five years ago), a volume that reflects customer confidence and the robustness of the infrastructure. Sales growth follows the same dynamic, with sales up of around 800% over five yearsand by 33% in the first quarter of 2025. To continue outpacing the web's hackers, the company is combining artificial intelligence detection with an enhanced offering. It has acquired Zorus (an American cybersecurity company specializing in web protection and filtration) to reinforce protection directly on computers and better understand suspicious behavior, as well as Guardian (an American cybersecurity company specializing in firewalls and VPNs) and Web Shrinker (which develops site classification tools) to improve its privacy and categorization tools (to quickly know whether a site is safe, dangerous, professional, etc.).

The industry is not stingy in recognizing DNSFilter's impact. The company was named " Best Network Security Solution " at the Tech Ascension Awards (an American program which annually rewards the most innovative technology companies in their field) and its CEO Ken Carnesi was named " Tech Titan " by the Washingtonian (an American magazine founded in 1965, which covers all the news from the American capital).
