In the digital era, where information is an invaluable asset, guaranteeing the integrity and confidentiality of data is a priority for companies. The use of VPNs (Virtual Private Networks) is presented as an increasingly suitable solution to address the challenges of digital security. However, are VPNs really as effective as they seem? VPNs and their promise of security: VPNs promise an extra layer of protection, creating an encrypted tunnel between the user\'s device and the server to which it connects. This, in theory, protects transmitted data against interception by unauthorized third parties. The logic behind the technology is simple: once the data is encrypted, even if it is captured by a hacker, it would become practically undecipherable without a correct key. However, not all VPNs are the same. There are significant differences in terms of the two security protocols used and the two levels of cryptography offered. Some companies opt for free solutions that may not be as secure as you pay, due to resource limitations or questioning practices in relation to the collection and sale of user data. Challenges and criticisms associated with the use of VPNs: Despite their apparent benefits, VPNs are not without criticism. Two of the most common arguments are that VPNs can create a false sense of security. At the same time, officials believe that the use of a VPN offers complete protection, ignoring that other attack methods, such as phishing, can still compromise corporate systems. Also, widespread use of VPNs can lead to legal compliance issues. Embora as VPNs help to circumvent geographical restrictions and censorship, their use may come into conflict with local laws in countries where these solutions are viewed as suspicious or prohibited.
