With the increase in internet use in companies, controlling internet access becomes essential to maintain information security and employee productivity . Thus, an increasingly common practice is to block inappropriate, harmful or out-of-scope .
The large increase in the number of cases of companies that have had their confidential data exposed or hijacked causes a lot of damage . Most of the time, a simple block of a malicious link in an email could prevent losses caused by security incidents or cyberattacks.
Wasting employees' time on websites outside their scope of work is a headache for managers. It is common for employees to access the corporate internet to carry out personal activities that are not related to work.
This situation can originate from several causes. From access to social networks , access to personal email or communication services such as WhatsApp or Telegram, for example.

Step 2: Install Lumiun Box
When you receive Lumiun Box access the control panel at https://app.lumiun.com . You will be asked for a serial number . Obtain this code from the label located on the bottom of your device .
Lumiun Box must be connected between the network gateway (normally the internet router) and the rest of the internal network equipment (normally a switch). Thus, all data traffic carried out between your local network and the internet will pass through the Lumiun Box .
- Connect network port #1 (named Internet) of the Lumiun Box to your internet router (internal network gateway).
- Connect another network port on the Lumiun Box to the internal network switch.

From that moment on, internet access requests from your network will be consulted on the Lumiun Box . This will make your network faster and more secure!

If the request is approved, access occurs normally. But, when the request is blocked, the user sees an informative page, which can be customized for your company.
Step 3: Monitor access reports
Before starting to block websites, it is recommended to monitor access reports for a few days. This way, business owners, IT professionals and managers can understand which websites employees access most.
In Lumiun Box you can monitor internet access in real time or view graphs with the most accessed websites , as shown in the images:
Step 4: Configure blocking of inappropriate websites
With information from access reports, it is more effective to decide and block websites in a timely manner.
In the example in Figure 6 , it is possible to identify that Facebook, Globo.com and WhatsApp are among the most accessed websites on the network. In this case, for this “Example Company”, these sites are outside the scope of work. Then, access must be blocked.
In Lumiun Box blocking websites can be done in three different ways: by applications (Facebook, WhatsApp, Banco do Brasil, etc.), by specific websites or by categories of websites (social networks, news portals, etc.).
Blocking by categories
To block website categories , simply access the “ Access control ” menu and the “ Website categories ” tab. See figures 7 and 8.
By default, all categories start free. Note that, in Figure 8 , we blocked the categories “ Games and Betting ”, “ Pornography and nudity ” and “ Social networks ” with just one click on each one. Quickly and easily, we were able to block all sites that belong to these categories.
Application blocking
If it is not necessary to block all websites in a category, there is the option to block by applications.
In the control panel, each “ Application” represents a website or internet service . So, grouping your different domains and addresses not only makes the configuration of rules much more efficient, but also the visualization of these accesses in the reports.
If you have already used another internet access control tool, you have probably already encountered the problem of needing to add several addresses to block or release a website and, effectively, control it.
For example, behind Facebook there are many domains that are used for its photo, video and sharing systems. In other tools, you would need to discover and configure rules for all these addresses , such as facebook.com, facebook.net, fb.com, facebook.com.br, fbsbx.com, scontent.fria1-1.fna. fbcdn.net etc.
With Lumiun Box it is much easier and more dynamic to block websites or allow access to an application.
Step 5: Increasing network security
Security menu , there is the option to configure the item that will reinforce the network's security layer.
The main objective is to restrict access to potentially unsafe websites , which can threaten information security by blocking harmful websites, as we will see below.

Finally, Lumiun Box generates reports that indicate the level of assertiveness . That is, the reports reveal whether blocking websites generated positive and effective impacts on productivity and data security in the company.
