Web Content Filtering

Flexible, frictionless content filtering.

Content filtering blocks unwanted web content and allows appropriate content, using website categorization to sort sites. DNSFilter filters at the DNS layer, so blocked domains never resolve.

CONTENT FILTERING THAT SIMPLY WORKS

DNSFilter gives you the flexibility to deploy protection exactly how you want, everywhere you need it. Protect your entire office with our best-in-class, traditional DNS filtering, or provide uninterrupted continuity for your roaming workforce with DNS PreCheck. 

By filtering content locally on the device, PreCheck ensures your acceptable use policies remain active even in conjunction with the most restrictive DNS settings and complex network configurations. Whether you need a network-wide solution or conflict-free endpoint enforcement, DNSFilter keeps your users safe and productive and your business protected, without adding friction.

BATTLING CHILD ABUSE ONLINE

We recognize that some websites should never be viewed. And more than that, when images of child sexual abuse are found online, they need to be removed. This is why we've partnered with the Internet Watch Foundation (IWF) and Project Arachnid. These organizations, are doing incredibly important work and we are proud to partner with them in their fight to end the cycle of child sexual abuse. The IWF and Project Arachnid's domain feeds are automatically blocked on the DNSFilter network and are the only category on our network that cannot be turned off.

CIPA COMPLIANCE

For schools or libraries that need to gain CIPA compliance, DNSFilter makes it easy. The Children's Internet Protection Act (CIPA) started in the early 2000s as a way to keep children safe online while in public places. CIPA compliance includes restricting access to inappropriate and harmful internet content while creating a safe and secure place for students to use online communications.

BLOCK WEBSITE CONTENT AT THE DNS LEVEL

When you filter website content at the DNS level, you’re able to block threats and traffic to inappropriate websites earlier than other methods like traditional firewalls. Blocking content at the DNS layer means fewer threats get through your defenses and inappropriate sites aren’t as easily circumvented. Stopping the DNS request means that a website you want to block is never seen by the end user, preventing any harm that can be done by that site.

FREQUENTLY ASKED QUESTIONS

WHAT IS CONTENT FILTERING?
Content filtering is the act of blocking unwanted web content and allowing “appropriate” or “favorable” content to be visitable. Content filtering can be enabled via software or hardware. The sorting of content into “good” and “bad” is made possible through website categorization. Without the ability to categorize a website, content filtering is not possible.
WHY DO YOU NEED CONTENT FILTERING?
Content filtering isn’t just about blocking disturbing, pornographic, or gambling sites. It’s also about blocking sites that are deemed a cybersecurity threat.
HOW DOES WEB CONTENT FILTERING WORK?
Unlike URL filtering, DNS filtering blocks domains. But more than that, it actually prevents domains from resolving. This is because when a DNS request is sent and the IP address is received by the DNS resolver, it doesn’t even send that information back to the end user. While content filtering at the DNS level means all pages on a website are blocked, it is much more secure for the end user.
WHAT IS THE DIFFERENCE BETWEEN DNS FILTERING AND WEB FILTERING?
Web filtering is the broader practice of controlling which websites people can reach, using methods such as URL, keyword or category filtering. DNS filtering is one way to do it: it blocks whole domains at the DNS lookup, so a blocked site never resolves. URL filtering can block individual pages, while DNS filtering blocks every page on a domain and stops the connection before it starts.
WHAT TYPES OF CONTENT FILTERING ARE THERE?
The common types are DNS filtering, which blocks domains before they resolve; URL filtering, which blocks specific pages; keyword filtering, which blocks pages that contain set terms; and category filtering, which blocks whole groups of sites such as gambling or adult content. DNSFilter combines DNS-layer blocking with website categorization, so you can block entire categories across every device.
