"Fallen Behind Other DNS Resolvers" Posted 2026-07-19
Pros: AI enabled first-seen ability to scan a website in real-time for unknown websites; great filtering and extremely fast resolver. Offers DNS relay servers with DoT. DoH is now offered for routers. Customer support representatives are very friendly, engaged, and extremely helpful. They work until there is a resolution. DNS relay server app was recently upgraded to include management ability, which has helped tremendously instead of needing to self-install.
Cons: Has fallen behind other resolvers with filters. No geographical blocking (only top-level domains; cannot block by regional IPs). DNSSEC support is limited (they actively discourage it). DNSSEC support is non-existent for DoH resolver. Many filter lists do not compare to competitors. IPv6 support is behind other resolvers. NAT addresses only allow you to specify an v6 or v4 address -- not both, which severely limits ability to use non-encrypted resolvers. No v6 support for the DNS relay server software, but they are supposedly developing it.
Overall: Not worth the price anymore. There are better alternatives. DNSFilter was once a leader, but has been surpassed even by the lesser known guys such as Control D for customization of blocks. Acquisition of Zorus has brought some additions to DNSFilter, but they have a lot to do to catch up on. Unfortunately, due to lack of features, we have decided to move our companies onto another platform.

"Excellent Content Filtering" Posted 2021-07-27
Pros: + Easy to use
+ One-click CIPA compliance
+ Users can submit unblock requests directly from the block page
+ Changes to block lists take effect instantly
+ The interface is fast and intuitive
+ Excellent supportCons: We'd like to have different filtering policies based on which VLAN the user is on. This can be done but it's a bit complex if you use Active Directory integrated DNS as we do.
Overall: DNSFilter is great at filtering malware and inappropriate content for our school. It's easy to use and cost-effective. We switched from Cisco Umbrella about 4 years ago and have been very happy with the switch. I'd highly recommend at least testing it out.
