What is a DNS Firewall?
First, you need to understand what a firewall is and what DNS is.
Basically, a firewall is a hardware and/or software device that monitors and controls the flow of data and internet access on a network, according to each company's security policy.
Above all, a firewall makes it possible to filter incoming and outgoing traffic and grant or deny specific and malicious access , in accordance with the set of legal and/or previously defined rules.
Undoubtedly, a firewall is one of the main defenses at the perimeter of a private network and an essential component in protecting against unwanted traffic and intrusion attempts.
DNS, which stands for Domain Name System , is a system that translates domain names (hosts) into IP addresses.
In practice, DNS makes using the Internet easier. Above all, because it's a service that allows you to type just one name into your browser's address bar to access the desired website – www.lumiun.com, for example.
Okay, now that we understand the terms, it's time to find out what a DNS Firewall .
A DNS firewall, or DNS firewall, is a step forward in the evolution of processes that ensure the security, control, and monitoring of data and internet access flows on a network.
Unlike a traditional firewall, a DNS firewall, in addition to blocking and redirecting users to prevent access to malicious websites, also acts more broadly, at different layers and phases than DNS, preventing the loss, blocking, or compromise of data .
In principle, this technology offers an advantage by providing more data on threats, helping to isolate compromised devices, and keeping information about malicious attacks visible and up-to-date through an automated threat feed, even with end-to-end encryption.
You can find more information about DNS Firewall in the article "What is DNS Firewall for?" on our blog.
Okay, now that we understand the topic, let's look at the reasons why you should (urgently) use a DNS Firewall system in your company.
7 reasons to use a DNS firewall in your company
Of course, there are more reasons besides the 7 mentioned here. However, these are the most important and relevant ones, especially for companies.
Managing access and protecting data and information, in a year when records for cyberattacks against companies were broken, is already a good reason to use the tool.
But without further ado, let's get to the reasons.
Reason 1: More control over the company's internet
Without any kind of control or policy regarding internet access, it is common for employees to use work time to access social networks, YouTube videos, WhatsApp, and other websites outside the scope of their work.
With an effectively implemented DNS Firewall system, several benefits can be observed, such as:
- Greater productivity and quality in the tasks performed.
- Protection against websites considered harmful.
- Faster internet through proper network usage.
- Monitoring and information about internet usage.
- Fewer occurrences of problems with viruses and malware.
Reason 2: Improves the company's internet security
This year has been marked by ransomware attacks against companies.
News and reports have been circulating weekly, and interestingly, DNS firewalls are a significant asset against ransomware attacks , as they prevent access to and block the opening of websites considered harmful. Here are some of their benefits:
- It blocks malicious links.
- It prevents access to harmful phishing websites.
- It prevents the opening of unknown links received via email.
- Blocks access to malicious ads.
- Blocks adult content that typically contains harmful links.
- It prevents the installation of software containing viruses and malware.
- Prevents identity theft and company data
To emphasize its importance, I would like to recommend reading the article " The Renner Case: Would the DNS firewall have prevented the ransomware attack?" where we detail the attack that occurred on August 19th of this year and left the fashion giant offline for 72 long hours .
In addition to this, if you have questions about how much it costs to keep your company's network protected against ransomware, the article " How much does it cost to protect your company against ransomware?" is a good read.
Reason 3: Improves team productivity
In addition to blocking harmful websites, using a DNS firewall on the company network can optimize the productivity of teams that use the internet daily.
By blocking social media for a specific group of employees, for example, it's possible to remove them from the distractions that these websites and apps can cause.
Not only social media, but also news sites, gossip sites, videos and music, entertainment, pornography, and even games and betting. Which categories and which employee groups can be chosen by the manager, including determining the times when access to this content will be allowed .
Reason 4: assists in complying with the LGPD (Brazilian General Data Protection Law)
The General Data Protection Law (LGPD) is legislation that aims to protect the freedom and privacy of consumers and citizens.
Since it establishes legal standards, all Brazilian companies and organizations must adapt to and follow the LGPD (Brazilian General Data Protection Law) and ensure control and transparency in the use of citizens' personal data.
Eventually, by failing to comply with the LGPD (Brazilian General Data Protection Law), companies and organizations (including public and governmental ones) may be fined or receive administrative sanctions .
But how does a DNS Firewall help with LGPD compliance? Simple: by following the principles of security and preventing the exposure of confidential data and information .
By using a DNS Firewall, the company's network and the data used daily by businesses are better protected in several ways, as we mentioned earlier in this text.
Therefore, it is clear that using a DNS Firewall tool effectively assists in complying with the LGPD (Brazilian General Data Protection Law).
Reason 5: Keeps the company's network and devices healthier
With an active and properly configured DNS Firewall system, the company's devices and networks can indeed remain healthier.
This is because, with active security filters and blocked access to harmful websites, the volume of access will be reduced, freeing up internet bandwidth for tasks that truly matter to the company, as well as reducing virus and malware infections on devices.
Using a DNS firewall on the company network optimizes internet and device usage, and also reduces equipment maintenance .
Reason 6: Reduces the need for team training
Providing cybersecurity training or implementing a company policy for safe and responsible internet use is an arduous task that requires commitment.
Imagine a company with 20 employees, and new ones are hired every six months. Conducting training and verifying that internet security instruction is being followed properly can be exhausting and time-consuming, and not always worthwhile .
The DNS Firewall reduces training needs , especially when it comes to the company's internet security, because it automatically blocks access to websites considered harmful or outside the scope of work.
Another interesting factor is that these access rules are generally implemented in a single panel, without the need for individual installation on each device. In other words, all devices connected to the company network will go through the filter , if that is your wish, of course.
Reducing the need for staff training on internet security and best access practices during work hours is one of the main reasons for using a DNS Firewall system in the company.
Reason 7: Installation is quick and easy
DNS firewall systems like Lumiun Box can be installed on a company network in 20 minutes.
With quick setup and no need for technical knowledge, the equipment sits at the edge of the network and does not interfere with the performance of the network or connected devices .
The equipment is implemented between the network gateway (usually the internet router) and the rest of the internal network equipment (usually a switch).
In this way, all data traffic between your local network and the internet will pass through the Lumiun Box.
After installation, the setup process is simple , and you will receive direct assistance from a member of the support team at every step.
