And this happens for several reasons, such as the lack of training of professionals in identifying suspicious messages, use of outdated systems, etc.  

In addition, with the arrival of the LGPD , the need for companies to protect their information and that of their customers has become even more urgent. This is because, in addition to the heavy fines imposed, the company's reputation is questioned in the market, negatively impacting its image.
