"Effortless, Powerful DNS Security with Seamless Management"

5/5

What do you like best about DNSFilter?

DNSFilter provides fast, reliable DNS-based security with an extremely clean and intuitive interface. Deployment is simple, whether using roaming clients or network-level enforcement, and policies are easy to manage across multiple sites and users. The real-time threat blocking, detailed reporting, and low false-positive rate make it a powerful yet lightweight security layer that works quietly in the background without impacting users. Review collected by and hosted on G2.com.

What do you dislike about DNSFilter?

Occasionally, initial tuning is required to whitelist certain business-specific domains, especially in specialized environments. However, once policies are dialed in, the system runs smoothly with minimal ongoing maintenance. Any limitations are outweighed by the platform’s stability, security effectiveness, and ease of management. Review collected by and hosted on G2.com.

What problems is DNSFilter solving and how is that benefiting you?

DNSFilter solves the problem of users unknowingly accessing malicious, phishing, or inappropriate websites by stopping threats at the DNS level before a connection is ever made. This significantly reduces security incidents, helpdesk tickets, and the risk of malware infections. It also provides visibility into DNS activity across on-site and remote users, allowing us to enforce consistent security policies regardless of location while improving overall security posture and operational efficiency.

"Effortless Deployment and User-Friendly Security Solution"

5/5

What do you like best about DNSFilter?

DNSFilter has become my preferred software within our security stack. Installation is straightforward, and I typically complete deployment on a local domain system in less than an hour, including the roaming agent setup. Users appreciate the software and find it easy to report blocked domains. Integrating DNSFilter with our existing systems was seamless, as both the user and developer experiences are very friendly. I rarely need to reach out to support, but on the occasions I have, Customer Support has been responsive and resolved my issues quickly. I use DNSFilter daily and frequently deploy it, and so far, I have found very little to dislike.

DNS FIlter as an organization is amazing, and very receptive to user feedback. I regularly have conversations with their teams about the product, and what can be done to improve or refine the solution. Review collected by and hosted on G2.com.

What do you dislike about DNSFilter?

I often need to switch between tenants. When someone reports a domain, I use the domain report tool to check why it is blocked. The tool also allows me to add the domain to either the universal allow list or the allow list for the current tenant. However, it would be more convenient if I could access all tenants' allow lists directly from this tool, instead of having to switch tenants and research the domain each time.

I will be submitting a feature request to further refine this. Review collected by and hosted on G2.com.

What problems is DNSFilter solving and how is that benefiting you?

Compliance and coverage are critical concerns. Many insurers now require a web filtering solution that protects all devices at all times. Our previous web filter, FortiGate Firewalls, only secured local networks, connected sites, and VPN-connected clients. This left a gap, as many employees could work without using the VPN, meaning they were unprotected and, as a result, not compliant with insurance requirements. By deploying this solution at the endpoint, users are now protected regardless of their location or VPN connection status.

DNS Filter also compensates for shortcomings in link scanning, an area where many email filtering solutions are lacking. With DNS Filter, web links in emails remain readable to users but are still filtered effectively. In contrast, email filtering solutions often rewrite links, and sometimes even then, malicious sites slip through. While some mail filters perform better than others, none seem to categorize and scan links as accurately as DNS Filter does as a dedicated provider. Review collected by and hosted on G2.com.

"Effective Phishing Protection, But Roaming Agent Issues Can Be a Hassle"

4/5

What do you like best about DNSFilter?

The filtering is effective and has saved our clients from getting phished. The most helpful category is new domains as attackers frequently use new domains that don't yet have a reputation. Their support is responsive and able to help. Review collected by and hosted on G2.com.

What do you dislike about DNSFilter?

One of the most common issues is when the roaming agent fails on a computer, which breaks name resolution on that computer. It's a simple fix when the user has admin rights to the computer, or the computer is on location and an admin can easily escalate, but we use a PAM software to escalate permissions, and that can't communicate to the internet if DNSFilter stops working. The few times that's happened, it's been a pretty big hassle to work around. The only other complaint is that you can't log in via SSO with M365 on their app.dnsfilter.com website; it requires a dedicated link for your M365 organization.

Thanks for the review, Matt. We're glad to hear that DNSFilter has helped your clients from falling victim to a phishing website. Because of the issues with the Roaming Client you've experienced, and since you're on a Windows machine, it sounds like you'll want to test our upcoming DNS PreCheck feature. You can read more about it at the link I've provided to our public-facing roadmap. If you ever need help with issues, don't hesitate to reach out to our support team.

"Highly Stable, Secure, and User-Friendly DNS Protection"

5/5

What do you like best about DNSFilter?

What I like most about DNSFilter is that they are open to feature requests and make it easy for us to submit them to the DNSFilter team. At the same time, we can also view existing feature requests. The development of new features like IP-related details in the log menu, which was requested by many users, made us very satisfied. Additionally, taking quick action for incorrectly categorized addresses in the Domain Report section is also very valuable to us. We were able to complete an easy setup thanks to the documentation provided by DNSFilter. It is a highly stable, secure, and user-friendly system. I would definitely recommend it and give it a score of 10. Review collected by and hosted on G2.com.

What do you dislike about DNSFilter?

Transferring logs from DNSFilter to a local SIEM or developing projects using API-supported applications such as webhooks can be somewhat challenging. Integrations are generally available with paid applications, and log forwarding is subject to additional fees. Review collected by and hosted on G2.com.

Öner, we really appreciate you taking the time to write such a nice review and giving us a 10/10! We are also glad to hear that you like how easy we make it for customers to submit new feature requests, and that you are actively submitting requests and feedback! I am making sure to pass your feedback around transferring logs to your SIEM to our product team so they are aware. If you need anything, please just reach out!

"Effortless Ad Blocking and Enhanced Browsing Experience"

4.5/5

What do you like best about DNSFilter?

Since using this product, I no longer have to worry about accidental clicks leading to disastrous consequences. It also does a great job of filtering out most of the distracting elements on websites, which means pages load more quickly and I use less bandwidth because advertisements and trackers are blocked. Review collected by and hosted on G2.com.

What do you dislike about DNSFilter?

Some legitimate websites that our staff and customers use are occasionally blocked, but this issue is simple to resolve by adding an exception for the affected site. Review collected by and hosted on G2.com.

What problems is DNSFilter solving and how is that benefiting you?

Phishing emails continue to be the most frequently used method of attack. DNSFilter serves as an additional layer of defense by blocking name resolution to harmful websites, helping to reduce the risk posed by this prevalent threat. By cutting down on unnecessary traffic, we are able to conserve Internet bandwidth and enhance employee productivity. Review collected by and hosted on G2.com.

"DNSFilter: Easy to Use with Fast Support, Minor URL Management Hurdle"

4/5

What do you like best about DNSFilter?

I like the ease of use that DNSFilter offers. It makes managing internet policies straightforward and efficient, particularly for an educational setting where creating boundaries for students can significantly boost their classroom focus. The prompt and efficient customer support is another aspect I really appreciate. Whenever I create a ticket, I always receive a quick response, which is essential for maintaining the service's reliability and effectiveness in real-time situations. Additionally, DNSFilter is valuable for its simplicity in resolving requests. If a teacher requests to unblock a website, I don't have to go through a lengthy processes or endure long waiting periods; it allows me to resolve the issue quickly and easily, which enhances the overall efficiency of using the product. Review collected by and hosted on G2.com.

What do you dislike about DNSFilter?

I find it cumbersome that when there's a website that needs to be unblocked, we have to manually identify and unblock not just the main URL but also its dependent URLs. If DNSFilter could automatically detect and unblock all the additional URLs a website relies on, it would greatly improve the efficiency of the process. Review collected by and hosted on G2.com.

Response from Serena Raymond of DNSFilter

Thanks so much for the review, Shant! We appreciate your feedback. It sounds like you might benefit from our AppAware feature, which blocks entire applications as opposed to individual domains. Using AppAware, you can block the domains associated with a single application (which as you point out, can be many domains!). If there is a particular application you're looking to block or not block, let our team know! We are regularly updating AppAware and are always looking for feedback.

"Overly Aggressive Blocking Makes Critical Websites Unusable"

0/5

What do you like best about DNSFilter?

nothing, see what i don't like answer , because there is not liked about it Review collected by and hosted on G2.com.

What do you dislike about DNSFilter?

It has a terrible blocking list; it blocks sites that should not be blocked URLs used and required for websites at Microsoft Azure to work on a continuing basis. It will blocks CSS and JavaScript includes, and sometimes it blocks AJAX calls, making it impossible to use the website.

It will block updates downloads for software that is well-known and from major software vendors.

It is so bad I have had to disable it so I can work with the issue.

We have a rule now, "if something doesn't work and it uses the internet, then kill DNSFilter and then see if it works." ; 99% of the time it does

After a support ticket, I can tell they don't understand the basics of how DNS lookups works. Review collected by and hosted on G2.com.
