Why Do You Need DNS Filtering?

In the new digital age, we can see that many companies are running a large part of their business digitally. In this digital business environment, companies hold a lot of data and information. Accurate storage and protection of company data and information are very important for company security. Companies and their managers, who are aware of the magnitude of this importance, make an effort to ensure security.

According to research, API gateway is the application and data-centric security technology that businesses utilize the most generally. Additionally, more than 60% of respondents said their business already deployed web application firewall solutions. Additionally, bot management was the data security tool that the majority of businesses planned to acquire in the upcoming 12 months.

There are many ways to protect your business environment against cyber threats by adding them to the block list and blocking malicious sites. Although the IP address is one of these ways and quite useful, when visiting websites DNS filtering blocks malicious websites and filters out sites that contain harmful and/or inappropriate content. DNS plays a huge role in stopping cybersecurity risks though.

What Is DNS?

Domain Name System (DNS) is a method of cataloging servers’ IP addresses and their associated web page URL addresses. As you might expect, remembering names is pretty easy, while remembering long-digit codes like IP addresses is extremely difficult. Thanks to DNS, computers know the connection’s destination. 

Each website is assigned a unique IP address and there are variations among them. DNS lookups translate IP addresses into URLs, which serve as connection request destinations. In the event that the server reacts, it sends the user back with the website loading. While you browse the internet, this process loops back on itself.

Additionally, to save time and resources, some devices’ IP addresses that are regularly used are occasionally kept. This is referred to as DNS caching, and it includes a speed dial of frequently used IP addresses. Operating systems and browsers usually keep DNS data in their caches for a certain period of time. 

What Is The Importance Of DNS?

These days, the biggest issue with cybersecurity is that it cannot be blocked and is very challenging to monitor in a commercial setting. Therefore, a number of technologies that strengthen DNS security close some of the vulnerabilities that hackers can use. Most of the time, DNS security solutions avoid or significantly reduce the dangers connected with DNS resolver systems that block spoofing efforts.

Protection From Phishing And Malware Attacks 

Carrying out corporate activities and safely storing data and resources are crucial for businesses. Any flaw, like a vulnerability, can lead to severe issues. In this aspect, DNS can be a rather potent option. 

DNS can be used to block dangerous websites linked to the distribution of malware or phishing. It can function as a filter to only allow trustworthy websites or to prohibit specific types of websites. By adding its known hosts to a blacklist, this occasionally also enables it to defend against advertisements.

Botnet Protection

It can be seen that IoT devices are now quite common. They pose a significant and serious risk of data and systems being breached and falling into the hands of hackers as their popularity develops. DNS connections to them can be terminated, thus neutralizing a danger, due to the fact that they are managed by well-known bot servers.

Quick Lookup

Compared to ISP DNS servers, secure DNS servers typically provide faster lookups. Additionally, they might have additional security features and filters that an ISP’s server might not have. Users may eventually benefit from increased connection speeds and enhanced reliability. By reducing time, it can also improve staff productivity. Lookup’s speed provides benefits and convenience to every company and IT team in many ways.

How Does DNS Work?

Every internet-connected gadget has a distinctive IP address. During data sharing, these addresses are utilized for identification. Knowing where to send data so that it can get to its destination is crucial. 

Web browsers often conduct these exchanges by consulting the DNS servers of their ISP. The DNS servers themselves can be categorized as either authoritative servers or recursive resolvers. Recursive resolvers know where to seek even though they don’t have the exact address, whereas authoritative servers store the actual IP addresses of websites. 

As customers can just recall a website’s name but DNS servers require lengthy IP addresses, this technique streamlines the user experience. Unknowingly, you utilize a DNS server each time you visit a website.

How Does DNS Prevent Cyberattacks?

Since DNS is responsible for connecting the internet, even minor adjustments can have a big impact on cybersecurity. 

In order to secure a company’s network, monitoring DNS requests and returning IP addresses from your corporation is crucial. One of the first stages in preventing an ongoing attack is to flag and audit abnormal DNS behavior. 

Another option to do this is to look for a DNS service provider who will let the usage of a privately managed DNS server. They feature specialized security protocols to thwart malicious DNS connections and can be set to detect suspicious activities. It is a very helpful feature because the assault can be entirely stopped and the connection is banned at the DNS layer.


As a crucial component of the internet with several vulnerabilities that can be exploited, DNS is a top target for attackers. It must be implemented correctly to get the most out of DNS and get maximum efficiency without disruption. This classification method, which will provide you with many conveniences and benefits, is also a great time saver and business facilitator for browsers and operating systems.

To find IP addresses to connect to computers and websites, users resort to DNS, a built-in domain name system that makes life easier for them. Of such great importance, DNS security should be one of the priorities when securing an organization against various cyber threats.
