Enterprise DNS web filtering solutions are security tools that protect users against unsafe or inappropriate web content. DNS filtering solutions work by filtering domains or IP addresses at the Domain Name System (DNS) level. When a user attempts to visit a domain, the request is sent to the DNS filtering solution. If the website appears to be malicious or is on a blocklist, the DNS filter service will block the employee from being able to access the requested web content.

DNS web filtering solutions are important tools to protect users against unsafe web content. Harmful websites can spread malware to company endpoints or can be used as part of phishing campaigns to harvest user credentials and compromise sensitive company data. On top of this, DNS web filters can be used to enforce company safe use policies. There are several categories of website content many organizations wish to block employees from accessing, such as adult content, gambling, and illegal materials. DNS web filtering solutions enable admins to enforce these compliance policies with ease and provide comprehensive reporting of user behavior online.

To help you find the right product, here’s Expert Insights’ list of the top DNS web filtering platforms. We’ll explore their effectiveness at web filtering, the threat protection they offer, the quality of reporting and the admin controls. The DNS web filtering solutions featured on this list are primarily SaaS-based, cloud-native tools, with key features including DNS-based web content filtering, policy creation, and flexible deployment.
