The importance of the firewall

 The firewall acts as a security device that protects the computer's doors and windows from threats, such as a hacker attack.


The tool filters the incoming and outgoing data packets, allowing or disallowing information traffic.


This procedure prevents the invasion of malicious software on the computer, ensuring the integrity of confidential files.


Implementing this security system in the company is an essential measure not only to guarantee the company's digital security, but also to prevent the company from suffering financial losses.


That's because, when faced with a threat, criminals can demand a bitcoin payment to recover lost data. Still, a hacker attack leaves the company vulnerable to bank fraud, as attackers can gain access to sensitive information.


In addition, installing a firewall in the company also allows IT staff and senior management to monitor employee access.


Thus, the company can be attentive to bad navigation practices, access to inappropriate websites and other online activities of employees, even preventing tax problems.


It is important to remember that, so that the company's machines and network are protected, it is necessary to be very careful when choosing the device that will be implemented in the company and also when configuring the filtering rules.


Therefore, the choice of the developer company must be made carefully, as well as the structuring of the firewall guidelines.


Other complementary measures can also increase the company's digital security. Actions such as implementing an antivirus and adopting security policies are effective ways to guarantee the protection of the organization's data.
