8 Best DNS Filtering Software in 2024

DNS filtering is a blocking technology that prevents users from loading specific web content. It is based on a predefined set of rules and is imposed by a DNS resolver.

DNS-based filtering is useful for businesses trying to restrict their employees from consuming NSFW (Not Suitable For Work) content or safeguard company devices from malicious sites. Likewise, schools (and parents) can configure their networks with DNS content filtering solutions to blocklist certain domains that they deem inappropriate or harmful.

Unfiltered internet access to websites can expose the device or network to malware, phishing, and other similar online threats. Moreover, DNS filtering is unavoidable in specific settings to preserve the sanctity of those environments and avoid malicious or undesirable content on websites.

The Geekflare team has researched, tested, and listed the best DNS content filtering tool based on factors like target audience, filtering capabilities, and malware protection.

WebTitan allows admins to set flexible policies for specific groups, networks, users, and devices from its dashboard. Teams can also manage and monitor everything remotely via its REST API.

Its malware protection is exceptionally robust in protecting users against zero-hour threats. This is backed by a crowd-sourced, real-time updating database built on the top of 500M website visits (as of this writing).

WebTitan supports user request identification with Microsoft Active Directory and Azure AD, allowing better control and detailed reporting. It’s a 100% cloud implementation that works for SAAS and on and off-network infrastructure.

Its reporting allows admins to look into real-time browsing sessions, provides performance and user activity overview, and alerts if anyone tries to access blocked content.

TitanHQ Pricing

TitanHQ lacks an upfront pricing structure. Instead, a business must enter the number of end users to get the quote. Currently, it shows £2.80/user/month for up to 25 end users. However, Managed Service Providers (MSPs) must contact the sales department for an estimate.

The platform’s interface provides clear visibility to parents and admins into network activity, including the rules being triggered and the domains getting blocked. Admins can also check specific profile activity and content consumption. CleanBrowsing supports creating groups and enforcing policies on its members.

The tool is compatible with encrypted DNS, with its native support for DNS-over-HTTPS (DoH), DNS-over-TLS (DoT), and DNSCrypt. This adds an additional security layer over the DNS requests to shield against man-in-the-middle attacks.

Cloudflare Gateway features a built-for-enterprise DNS server network to enforce flexible content policies, monitor user activity, and block zero-day threats.

Businesses can build and deploy content policies for their applications and private networks to adhere to organizational policies. Gateway supports temporary authentication, purpose-specific authentication, third-party identity providers, and standard SAML and OIDC connections.

Cloudflare Gateway lets admins enforce built-in policies and allow granular access to content based on geolocation, device, IDP groups, external APIs, and more. It also comes with HTTP(S) filtering, which enables blocking traffic based on their source, domain, hosts, and country, among others. Additionally, teams get firewall filtering to allow/block traffic based on ports, IPs, and TDP/UDP protocols.

In addition to using Cloudflare’s global network of servers, teams can also use a local DNS server to resolve private queries. Moreover, it also allows for the setting up of DNS protection for physical locations.

Businesses get detailed reports indicating every request, device, and user and why a specific request was blocked. For organizations that already experience the benefits of Cloudflare, Gateway must be considered for all their website content filtering needs.

Cloudflare Gateway Pricing

Cloudflare Gateway has a generous free plan covering 50 users at once. The entry-level paid plan adds more perks, such as a 100% network uptime SLA, tech support, unlimited users, and more, for $7/user/month.

6. OpenDNS

OpenDNS (from Cisco) offers a free DNS service for individuals and small businesses.

It provides two options: Family Shield and Home. The major differentiator between the two is the ability to add custom DNS filters, which are available with OpenDNS Home. Its free plan requires users to register with OpenDNS, whereas Family Shield works without any account.

OpenDNS Family Shield is pre-configured with filters to block adult content. It’s simpler to use and only needs DNS redirection to work, making it one of the best DNS family filtering solutions.

Both plans share malware protection, parental controls, and email support.

While OpenDNS is suitable for personal use cases, enterprise implementation is handled by a related product, Cisco Umbrella. This offers much more than DNS filtering, such as SWG (Secure Web Gateway), CASB (Cloud Access Security Broker), RBI (Remote Browser Isolation), and ZTNA (Zero Trust Network Access).

What is DNS Filtering?

DNS filtering is a technique for sifting internet traffic based on the requests made to the DNS resolver. This technique is used to improve the end user’s online experience.

This is practised in corporate and personal environments, where device admins redirect DNS queries to a DNS filtering software, stopping users from consuming specific content categories (ex., entertainment, adult, etc.) and visiting malware-infected websites.

Benefits of DNS Filtering Solutions

DNS filtering is one of the simplest steps businesses and individual users can take to maintain good cyber hygiene without impacting the performance of their local devices. It has 3 major benefits, as stated below.

• Safe Internet Browsing: DNS-level attacks, such as DNS cache poisoning, are subtle and difficult to detect. With these attacks, users end up at websites with malicious content even after entering accurate URLs in their browsers. In such cases, DNS filtering protects unsuspecting users from hidden internet dangers.
• Data Protection: Giving out personal and financial details to fakes or replicas of genuine websites (such as banking and social media sites) is commonplace. DNS filtering ensures users do not fall victim to website spoofing.
• Device Protection: Many DNS filtering software, such as DNSFilter, update their threat database in real-time. This stops users from visiting harmful websites or accidentally downloading malware to their devices.

How to Choose the Right Best DNS Filtering Solutions?

Choosing the right DNS filtering solution involves identifying business requirements and comparing leading providers based on user feedback and scalability. There are 4 main points to consider when choosing a DNS filtering solution, as shown below.

• Identify Your Needs: Businesses and individuals should decide on the deployment option. A few, such as WebTitan, provide options for on- and off-network DNS filtering. Users must ensure the DNS filtering company has roaming agents covering end-user devices. Additionally, features like granular access control, reporting, and integrations with third-party apps are crucial in specific settings, such as for enterprise customers.
• Compare Providers: The second-best way to compare providers, after trying them out yourself, is to read articles from reputed publishers like Geekflare. We thoroughly test and compare such business tools before giving out verdicts. Alternatively, teams can analyze DNS filtering providers based on their filtering categories, deployment options, scheduling, and more.
• Check Reviews and Testimonials: User feedback is key to understanding a service’s benefits and disadvantages, and DNS filtering services are no exception. It gives a decent idea about ease of use, customer support, and whether the service’s features work as advertised. Check out software review websites like G2, Capterra, Geekflare, and forums like Reddit, to learn more about a service’s features and performance.
• Future Growth: Barring a few providers, most DNS filtering services are priced on a per-device basis. This helps users know if the service provides scalability without charging exorbitant prices.
