What is Firewall DNS?
First, you must understand what Firewall is and what DNS.
Basically, a firewall is a hardware and/or software that monitors and controls the flow of data access and the network in network, according to the security policy of each company.
Above all, a firewall enables filtering input and exit traffic and granting or preventing specific and malicious access , in accordance with the set of legal rules and/or previously defined.
Surely firewall is one of the main defenses on the perimeter of a private network and an essential component in protecting unwanted traffic and invasion attempts.
Already DNS, comes from the English Domain Name System . It is a system that “translates” the names of domains (hosts) to IP addresses.
In practice, DNS facilitates the use of the internet. Above all, because it is a service that makes it possible to enter only one name in the browser address bar to access the intended site - www.lumiun.com, for example.
Well, understood what the terms are, it's time to find out what Firewall DNS .
Firewall DNS or DNS Firewall, is a step further in the evolution of processes that ensure security, control and monitoring of data access flows and network internet.
Unlike a traditional firewall DNS Firewall, in addition to blocking and redirecting users in order to avoid malicious websites, also acts more broadly, in layer and different DNS phases, avoiding loss, blocking or data impairment .
In principle, this technology allows an advantage that provides more data on threats, helps to isolate committed devices and maintains visible and updated information about malicious attacks through an automated threat feed, even with end -to -end encryption.
Can you see more information about Firewall DNS in the Firewall DNS article for what? on our blog.
Well, understood on the topic, let's reasons for you to use (urgently) a DNS firewall system in your business.
7 reasons to use DNS Firewall in the company
Of course there are more reasons besides the 7 cited here. However, here are the most important and relevant to companies, especially.
Managing access and protecting data and information, in the year when recording cyber attacks against companies were beaten, it is already a good reason to use the tool.
But without delay, let's go to the reasons.
Reason 1: More Internet control of the company
Without any type of internet access control or policy, it is normal for employees to use their working time accessing social networks, videos on YouTube, WhatsApp and other websites outside the scope of their work.
With a DNS firewall system effectively implemented, several benefits are perceived as:
- Higher productivity and quality in the tasks performed
- Protection against websites considered harmful
- Faster internet for proper use of the network
- Monitoring and information on the use of the internet
- Lower occurrence of problems with viruses and malware
Reason 2: Improves company security of the company
This year was marked by ransomware attacks against companies.
News and reports have been reported weekly and curiously, Firewall DNS is an important asset against ransomware attacks , as in various ways, avoids access and prevents the opening of sites considered harmful. See some benefits:
- Malicious Links Block
- Prevents access to harmful phishing sites
- Prevents the opening of unknown links coming by email
- Blocks access to malicious ads
- Blocks adult content that normally contains harmful links
- Prevents the installation of software containing viruses and malware
- Prevents theft of identity and company data
To emphasize the importance, would you like to indicate the reading of the article Case Renner: Did DNS Firewall avoid the ransomware attack? Where we detail the attack on August 19 this year and left the offline fashion giant for 72 long hours .
In addition, if you have questions about how much it costs to keep the company's network protected against ransomware, the article how much does it cost to protect your business from ransomware? It is a good reading.
Reason 3: Improves team productivity
In addition to blocking harmful websites, using Firewall DNS on the company's network can optimize the productivity of the internet that use the internet daily.
By blocking social networks for a particular group of employees, for example, it is possible to remove them from the distractions that these sites and applications can cause.
Not only social networks, but also news sites, gossip, videos and music, entertainment, pornography and even games and bets. Which categories and which groups of employees can be chosen by the manager, including determining access to these contents will be allowed
REASON 4: Aids in adaptation to LGPD
The General Law on Personal Data Protection (LGPD) is legislation that aims to protect the freedom and privacy of consumers and citizens.
Once it establishes legal standardization, all Brazilian companies and organizations must adjust and follow LGPD and ensure control and transparency in the use of personal data of citizens.
Eventually, by not complying with LGPD, companies and organizations (including public and government) may be fined or receive administrative sanctions .
But how does a DNS firewall help in the suitability to LGDP? Simple: Following the principles of security and prevention of data exposure and confidential information .
With the use of Firewall DNS, the company's network and the data that is used daily by companies are more protected in various ways, as mentioned earlier here in the text.
Thus, it is clear that using a DNS Firewall tool acts effectively in adjusting LGPD.
Reason 5: Maintains the network and devices of the company healthier
With an active and properly configured DNS firewall system, company devices and networks can remain healthier.
This is because, with active security filters and access to harmful websites, the volume of hits will be reduced, making the internet freer to the tasks that really matter to the company, and reduce the infection of viruses and malware in the devices.
Using DNS Firewall on the company's network optimizes the use of the internet, the devices and also reduces equipment maintenance .
Reason 6: Reduces the need for team training
Providing cyber security training or implementing a policy of safe and conscious use of the company's internet is an arduous task and requires commitment.
Imagine a company with 20 employees, and each semester new are hired. Training and verify that the teachings about Internet security are being properly followed can be tiring to take a time that is not always paid .
Firewall DNS reduces training needs , especially when related to the company's internet security, as it automatically blocks access to websites considered harmful or outside the work scope.
Another interesting factor is that such access rules are made generally in a single panel, without the need for individual installation on each device. That is, all devices connected to the company's network will pass the filter if this is your wish, of course.
Reducing the need to training teams safely on the Internet and good access practices during working hours is one of the main reasons for using a DNS firewall system in the company.

Reason 7: Installation is fast and easy
DNS Firewall Systems such as Lumiun Box can be installed on the company's network in 20 minutes.

The equipment is implemented between the network gateway (usually the internet router) and the rest of internal network equipment (usually a switch).
