Firewall for companies: understand the importance (and increase your security!)

When we talk about information security, the firewall is one of the most known and important solutions for companies. Although the topic of data protection has been gaining more and more visibility in recent times, many businesses (especially small and medium-sized ones) still sin a lot in their day-to-day processes.

In this sense, it is worth noting that Brazil is the seventh country with the most hacker attacks in the world, which reinforces the urgency of the matter and places cybersecurity at the top of the managers’ concerns.

Next, we gather the main information about the firewall for companies and clarify the most common doubts about this valuable ally of corporate security. Check out fastest vpn for torrenting!

After all, what is a firewall in the context of companies?

In a nutshell, the so-called “firewall” is a network security mechanism. In practice, it is a device that acts as a filter that monitors all incoming and outgoing traffic, authorizing or blocking certain traffic in accordance with the defined security rules.

The firewall thus prevents unauthorized access to the connection between devices, increasing the reliability of corporate computers and preventing virtual attacks.

It is worth adding that the mechanism can be based on software or hardware. When it comes to software, it works like an application (which already integrates most new operating systems). Hardware, in turn, is the most used modality in companies – in these cases, it is a device with the specific function of monitoring traffic.

This type of firewall is more used in business because it does not require sharing resources with other applications. This way, you can apply your filters more quickly, in addition to offering greater operational capacity.

Firewall types

Given the different types of firewalls on the market, it is normal for managers to have difficulties in making the best decision. Among the main options, we can mention:

  • Traditional firewall (with state inspection);
  • Proxy firewall;
  • UTM Firewall;
  • NGFW firewall (next generation);
  • NGFW firewall with a focus on threats.

The choice of the most appropriate mechanism depends on factors such as the objective, the reality and the needs of each business. It is often interesting to have the support of an IT consultancy to obtain specialized support in the process.

Corporate firewall: why is it so important?

To get an idea of ​​the dimension of the importance of a good firewall, just remember that, today, most of the work routines of companies depend on the internet connection, and the online environment is a high risk environment.

In this scenario, the firewall acts as a true “front line of defense” in the control and protection of data. In conjunction with antivirus and other security practices – such as backup – the mechanism is indispensable for reducing threats and protecting equipment against viruses and other cybercrimes.

As a result, process efficiency and better productivity benefit the team, which does not have its activities interrupted due to virtual attacks.

It is important to remember that, in practice, the firewall allows the management of permissions to access the internet, granting more control to the administrator, who authorizes or not the connection to certain sites by the employees.

This control, for example, can take place by company hours or sectors, depending on the responsibilities and needs of each group of employees. Accessed content, websites and applications can be managed and monitored.

In this way, it is possible to guarantee the company’s interests, greater data protection and optimization of work routines. The availability and agility of the internet, even, present significant improvements, since access is prioritized and strategically distributed.

In general, achieving more security makes it possible to run more consistent and available systems, increasing team productivity and reducing failures in day-to-day operations.

Firewall: special importance for SMEs

It is also worth adding that the implementation of firewalls gains special importance when it comes to small and medium-sized companies.

These businesses, mainly because they tend to have less organized and more fragile infrastructure and security practices, are more vulnerable to cybercrime. In this scenario, the implementation of the firewall (without forgetting a good corporate backup strategy) is often the main way to ward off cyber threats and ensure the security of corporate data.

How to implement a firewall for companies?  

In the case of locations that already have a firewall running, the implementation of a firewall is simpler, and considering that the most difficult initial phases have already been carried out – now, all you need to do is update or perform an upgrade.

In these situations – once the rules, settings and privileges have already been defined – it is a great time for the company to correct inefficiencies and rethink the established rules, taking the opportunity to increase the process.

In turn, businesses that are adopting the solution for the first time will have to invest in a lot of planning to order the environment and set clear standards effectively and with organization.

It is worth remembering, here, that it is often necessary to count on the resistance and even the dissatisfaction of the team – it is natural that changes generate possible conflicts. In this sense, explaining and clarifying the benefits of implementing the mechanism for employees is essential.

Briefly, the necessary actions to implement a firewall effectively are:

  • Establish access rules and profiles: to begin, define what can be accessed by employees. With the solution, each team can only access secure sources and content that is relevant to their work. It is important to involve managers, directors and the IT manager in the process;
  • Determine Virtual Private Network (VPN) settings: VPN is a possibility to grant secure and remote access to data stored on servers. The network is common in businesses that have branches and employees acting remotely. Assess the security conditions of this access;
  • Define filter rules: now, elaborate the rules that will define how traffic control will be done via gateways (“access doors”). Each port will have a set of rules, and it is possible to create navigation exceptions for certain computers.

Increase the security of your business information!

Remember: having control over what travels between the internet and servers is a fundamental first step towards information security in the business. In a world in which cybercrime is increasingly common, betting on smart solutions to protect your data is essential!
