DNS: Top 6 Reasons Why DNS is Important


By blocking harmful websites and screening out undesired content, DNS protection adds an extra layer of security between a worker and the internet. Employees can reduce unrequired risks and the possibility of malicious assaults by utilizing secure DNS servers at both their homes and place of employment. Here is all the information you require regarding the advantages of encrypted DNS servers.

What is a Domain Name System (DNS)?

Easy-readable names, such as etechsupport.com, are transformed into an IP address by the Domain Name System. This enables users to utilize memorable domain names as opposed to having to memorize the numbers. The DNS has been a key piece of the Internet infrastructure that has facilitated user-friendliness. It can be used to promote safety as a layer of intermediate between users and the internet.

The foundation of internet domain name security is not provided by a single DNS server, but rather by several DNS services. Many individuals utilize the DNS server that their ISP offers, but they are not required to. Instead, they might make use of a commercial or free-protected DNS server. Since the majority of Internet connections pass through a DNS, DNS Protection offers a fantastic chance to increase security.

Why is DNS security essential?

In an emergency directive, the Department of Homeland Security urged US companies to take precautions against DNS hijacking. The instruction claimed that recent DNS assaults had been confirmed by FireEye and Cisco.

Both public and private networks can benefit from DNS protection. It’s crucial to safeguard home networks since so many people have noticed a blurring of the lines between their personal and business lives. In addition to delivering more advantages, a secure DNS solution may be utilized to enhance BYOD policies by protecting data both internal and external of the company.

A safe DNS option will offer the following:

1. Content filtering

Content filtering can therefore be used to prevent access to 18+ websites and other undesirable content. This has a significant advantage over other filtering options because it works through the DNS and doesn’t need any application to be installed on PCs or other devices. The content screening will lessen the likelihood that a worker will go to a “bad area” and become the target of a malicious assault.

2. Blocking malware and phishing

Phishing and malware blocking prevent access to websites that may include frauds, infections, or other potentially harmful content. Many people find it quite challenging to recognize phishing efforts. When combined with the appropriate training, a content filtering measure that can bar recognizable phishing attempts can lower the likelihood of falling for this kind of attack. Unfortunately, this does have one drawback that is blocking by itself is powerless to stop increasingly sophisticated phishing attacks.

3. Security against botnets

Protection from botnets is a particularly hazardous issue that is growing as IoT (Internet of Things) devices become more widely used. Your device will be protected by botnet protection, which will take action to prohibit connectivity with known botnet servers.

4. Advertisements blocking

Blocking advertisements is one method of content filtering. Advertisements might contain dangerous software or make an effort to get information from staff members. Advertisements can hurt a system’s performance and a worker’s productivity even if they aren’t specifically malevolent.

5. Typo correction

Correction of a typo, such as changing “yutube.com” to “youtube.com.” This is crucial because harmful attackers frequently buy these “typo” domains to spread dangerous software or gather data from them. While a “typo” domain may appear identical to the ordinary domain in every way, it may also gather your data after you enter it.

6. Enhanced speed

increased speed, which raises productivity and efficiency. Protected DNS servers frequently offer faster lookup speeds than DNS servers offered by an ISP. Additionally, secure DNS servers might improve dependability. DNS resolution is utilized frequently during the internet connection process, therefore even a small improvement can result in noticeably better performance.


Depending on your demands, there are free and premium DNS-level protection options available. You can locate services and comparisons by searching for free DNS-level protection solutions but you might also want to think about using a commercial DNS provider. Advanced control options are available with pro accounts, such as complete control over whitelisting and blacklisting. Even if a commercial DNS server could be quicker or more dependable compared to a free one, the latter is nonetheless incredibly useful.

You can install the appropriate protected service on staff work devices once the relevant one has been identified, ensuring that the laptops and PCs are constantly connecting through a secure portal. Staff personnel should be obliged to use the encrypted DNS server if they intend to accomplish work tasks on their own devices. Both their desktop computers and their phones will be protected by the server.

From there, a further layer of protection and content filtering will be added by the DNS server between your staff and the internet. Taking an active role in your firm’s security is crucial to lowering risk. Contact eTechSupport if you want to start protecting your data right away.
