A VPN is a service that you can use to ensure that your online activities are protected and safe from unwanted things. Things that are not desired here are the interception of important data or information by hackers or cybercriminals or exposure to your privacy from irresponsible parties. When you are connected to the internet, information about you can be obtained easily, the computer used, IP address, geographic location, browsing history, personal data, your activities, and so on. Your important data can be stolen or intercepted for sale or ransom purposes. Your privacy can be exposed to serve ads or service offerings and so on. That is why you need to use the additional info because you need a way to do things online safely.
VPNs provide advantages or benefits related to data or information security and privacy. When accessing the internet using a computer or smartphone device, your device is uniquely assigned an IP Address. The problem is, all your online activities can be traced to that IP Address. When you use a VPN, the VPN will disguise the IP address and transmit data or information as if it comes from the VPN server you are using. Thus, your IP Address, geographic location, your identity, your online activities will remain safe and not be tracked or exposed.
Free public Wi-Fi is everywhere, but connecting to the internet using free public Wi-Fi puts your data security and privacy at risk. It is highly recommended that you be more careful about using existing free public Wi-Fi. Even though free public Wi-Fi networks use passwords, the reality is that Wi-Fi passwords are easy to crack or discover so your important data remains insecure. With a VPN, data is encrypted as if there was a hidden tunnel specially made for your data transmission. Thus, your data will be protected, it is impossible to read it to be stolen or tracked.
