DNS protection solutions have become one of the core tools that enterprises use to protect themselves against threats online and avoid unnecessary costs. In this article, we’re going to look at the eight best DNS protection solutions for your network, but first, let’s look at what DNS is and what protection tools do.

What is DNS?

The Domain Name System or DNS acts as an online phonebook. The DNS is used to convert a domain name into an IP address for a device to connect to. DNS is used because it’s easier for the user to remember a domain name rather than a long-winded IP address. When you enter a search query into your web browser the DNS server translates it into the IP protocol that enables the computer to open the site.

What are DNS Protection Tools and Why Do I Need Them?

If left unprotected, the DNS is vulnerable to being tampered with by cybercriminals. For example, malicious entities can create false DNS records and fool legitimate users into visiting fake websites and downloading malware. An unfortunate interaction between the DNS server and a compromised site can result in:

  • DDoS attacks
  • DNS hijacking
  • Cache poisoning
  • Botnets
  • Man-in-the-middle attacks

DNS protection tools are designed to prevent cyber attacks by acting as an intermediary between your web browser and the websites/content you access online. DNS protection software can block compromised sites, block known botnet servers, filter content such as advertisements or adult sites, correct domain typos, and more.

The Best DNS Protection Solutions

Our methodology for selecting a DNS protection solution for your network

We reviewed the market for DNS protection systems and analyzed tools based on the following criteria:

  • A cloud-based system
  • Threat intelligence that is constantly updated
  • A resolver that will handle all of your user’s external DNS requests
  • Safe browsing features that scan Web pages for malware
  • Optional content filters
  • A free trial or a money-back promise so you can try a service before committing to it
  • Value for money that is provided by a solid and reliable service but at a fair price

With these selection criteria in mind, we looked for reliable systems that will provide a constant DNS resolver for your users when accessing external Web destinations.

Essentially, a DNS protection tool acts as a buffer that limits your exposure to online threats. Ultimately, how safe you are, depends on the quality of the product that you’re using. Let’s take a closer look at what’s available.

1. CleanBrowsing

CleanBrowsing DNS Dashboard

CleanBrowsing is a DNS resolver that performs filters and blocks on Web requests before responses are delivered back to the Web browser.

A DNS resolver doesn’t store the cross-references between URLs and IP addresses, it fetches the relevant record from another DNS service. On receiving the address of the requested Web page, the CleanBrowsing system scans that page and checks that it is genuine and doesn’t include downloaders for Trojans or other malware. If the page checks out, the DNS resolver returns its IP address to the requestor.

Key Features

  • Easy Setup and Deployment: it makes web security basic. Simply change your DNS settings on any device or router to begin using their protective services — no complex installations are required.

DNS Protection FAQs

Is DNS a security risk?

DNS isn’t a security risk directly but manipulation of DNS records is a deception technique that can lead a Web user to a fake site or can be used to block access to sites.

How do I secure my DNS traffic?

It is possible to secure DNS traffic by applying encryption for the connection between your network gateway and the DNS resolver.

Does VPN prevent DNS hijacking?

Quality VPN services include a private DNS system. This performs DNS fetches within the VPN tunnel, removing reliance on the ISP’s DNS system, which could be controlling your internet access through DNS hijacking.
