DNSFilter is a reliable and efficient solution that is widely used by managed service providers to augment security for the organizations they support. Users have praised the ease of deploying mobile agents, which do not require installation on every machine thanks to the fixed IP address for each site/location. By providing extra security and acting as a compliance check box, DNSFilter ensures that unwanted internet content, such as malware, phishing sites, and other malicious content, is filtered and blocked. Administrators can easily set custom policies, create whitelists and blacklists, and perform web filtering and blocking with advanced threat protection.

Furthermore, DNSFilter offers integrations with CRM, SIEM, and SSO systems, enhancing its capabilities for businesses. Users have noted that once the initial setup is complete, day-to-day maintenance is minimal. With DNSFilter in place, organizations can keep their employees' browsing safe by proactively blocking suspicious or inappropriate web content like adult websites, streaming platforms, and gambling-related sites. Its user-friendly interface simplifies the process of adding specific websites to a whitelist or blacklist. Additionally, DNSFilter's fast DNS lookups and easy list management facilitate efficient business URL filtering.

Another aspect appreciated by users is the reporting feature of DNSFilter, which provides valuable insights into network activity. Despite its functionality and effectiveness in enhancing security measures, DNSFilter is reasonably priced. Managed service providers also utilize DNSFilter to secure both internal and client web traffic effectively. The remote agent provided by DNSFilter ensures the safety of laptops on external networks while deployment at a firewall level for internal networks saves time and efficiently handles DNS and content filtering. Overall, DNSFilter proves to be a reliable solution that addresses various security concerns for organizations while offering ease of use and valuable features.

They feel that the software only focuses on one aspect and does not provide additional functionalities that could enhance their experience. It is suggested that DNSFilter should consider incorporating more diverse features to meet user expectations.

Our company uses the product for handling business URL filtering. The DNS lookups are fast and the management of lists is pretty easy. Reporting is useful. The price is reasonable for what it does. This is a great window of opportunity to surf internet.
  • First of all value for money
  • Secondly ease of use is excellent
  • Safe internet to all
  • Reports could be generated easily
  • Price could be revaluated for enterprise domain
  • Block pages could be configured easily
I like how easy it is to manage the filtering software from the web portal. It's super straightforward to set up my networking equipment with clear instructions. I like that it automatically blocks threats without me having to do anything. It also lets me remotely manage both of our locations and networks from the same portal with the same policies. Very useful for saving time setting up content filtering.

Our organization uses DNSFilter to keep employee's browsing safely with it's threat protection and content filtering. It allows us to keep our users from navigating to suspicious or inappropriate web content such as adult websites, streaming websites, and gambling-related sites. With DNSFilter, it's easy to add specific websites into a whitelist or blacklist quickly & painfully simple.
  • Content Filtering
  • Threat Protection
  • Detailed Reporting on Network Activity
  • DNSFilter doesn't have IP layer filtering like other products in it's space
For the price that DNSFilter is offered, we find that it is extremely well suited for organizations of all sizes. One of the best features of DNSFilter is that is extremely easy to deploy, and falls into our "set it and forget it" list of tools. When we are actively using DNSFilter, we find that the UI is simple, clean, and well thought out. DNSFilter is effective at keeping our users off malicious, suspicious and undesirable content online.

We use DNSFilter to filter and block unwanted internet content, such as malware, phishing sites, and other malicious content on our website domain. It also allows administrators to set custom policies and create whitelists and blacklists of specific sites. We used it for web filtering and blocking. Also Advanced threat protection and it has been helpful.
  • Web filtering and blocking
  • Advanced threat protection
  • URL and domain filtering
  • Improved scalability: As an organization's needs grow and evolve, the software should be able to scale up and handle an increasing number of users and devices.
  • More granular controls: The ability to set more detailed and specific policies, such as the ability to block certain types of content for specific groups of users, would give organizations more flexibility and control over their internet usage.
  • Advanced threat protection: Increasing the software's ability to detect and protect against advanced threats such as zero-day exploits and APTs would provide a more comprehensive security solution.
Block access to malicious or unwanted internet content: DNSFilter's ability to block access to known malware, phishing sites and other types of malicious content can help protect organizations from security threats and data breaches. Enforce internet usage policies: By setting custom policies and creating whitelists and blacklists of specific sites, organizations can control and monitor how their employees and other users access the internet. This can help to prevent employees from visiting non-work-related sites and potentially expose the organization to security risks. Monitoring and track internet usage is a good use case too. DNSFilter's reporting and analytics features can help organizations understand how their employees and other users are accessing the internet, identify potential security risks, and make more informed decisions about their internet usage policies.

Coming from OpenDNS, to Webroot DNS we finally landed at DSNFilter and won't be going back. The page filtering is important part of our stack to stop all potential unwanted end user actions. They offer tons of integrations with our CRM and SIEM and SSO. While the initial setup isn't very MSP friendly, once the setup is complete the day-to-day maintenance is minimal
  • Web Content Filtering
  • Bulk import on setup
Web filtering is vital part of any MSPs stack, users will inadvertently or purposefully click on things that they ought not and no matter the training, it still can and does happen. DNSFilter is a great first line safety net to stop bad actions before they can even start.

DNSFilter is used as a part of the base security suite we require all clients to have, currently that means we have it deployed to around 700 endpoints. We strongly feel DNS filtering is a must-have service for all clients and wanted something that was set up and forget and DNSFilter fit the bill perfectly.
  • Ease of Use
  • Ease of deployment
  • Simple to Understand Reporting
  • Upgrades of Laptop Clients
  • Handling of Dynamic IPs and custom domains
  • Documentation
DNSFilter is well suited for the MSP market as its simple setup and deployment means there is not a lot of management cost included, this allows us to include it in our security stack with little additional cost. We can set up base policies that work for 99% of clients right from the start so no need to reinvent the wheel with every deployment.

We are an MSP who is using DNSFilter services to augment security for the organizations we support. The service is reliable and the mobile agents are pretty easy to deploy. Having a fixed IP address for each site/location is important so you don't have to deploy agents on every machine. We had some troubles off/on for a bit with agents randomly switching to roaming mode but I don't think we've had an issue since they implemented the local DNS and domain fields. The extra security above what our endpoint protection and firewalls provide is good and provides us with another check box for compliance.
  • Security
  • Compliance
  • DNS
  • Nothing
  • Does one thing well
  • No need for extra features
Augments existing infrastructure (endpoint protection and firewall) to filter bad sites from Internet. Works fine for MSPs as you can compartmentalize each customer and to integrate billing.

We use DNSFilter across all of our clients as well as internally. We forward all DNS traffic to DNSFilter and it provides us with peace of mind knowing both our internal and clients web traffic is secure. DNSFilter also offers a remote agent that we install on laptops that keeps them safe when they are on networks outside of their internal business networks.
  • Web filtering
  • Remote agent
  • Console is easy to use and manage
  • Updates to policies are instant
If you have a need to secure web traffic and block unproductive and inappropriate sites, look no further then DNSFilter. It is very easy to deploy and manage. You can manage multiple sites, locations, customers from within a single pane of glass which saves major time. Policy changes are instant and you can customize the block screens.

We are a managed service provider. We have multiple clients across many different verticals. We deploy DNSFilter at a firewall level for internal networks and leverage their roaming client for all laptops. We are able to sleep a little better at night knowing DNSFilter has our back. DNSFilter handles DNS and Content Filtering very efficiently and allows us no not waste time.
  • Content Filtering

I would personally recommend DNSFilter to anyone looking for an extra layer of protection in today's ever-changing threat landscape. DNSFilter is very affordable, easy to set up, and even easier to manage. It will save you time and money by protecting web traffic and keeping users away from inappropriate and malicious sites.
