How a VPN works
When connecting to a VPN, the device communicates with a VPN server, which then connects to the Internet on behalf of the user. This process masks the IP address, making it appear that the user is not accessing the Internet from their real geolocation, but from the location of the VPN server.
Encryption: the Internet’s privacy shield
A key feature of a VPN is encryption. Data transmitted over a VPN connection is encrypted, that is, converted into a code that prevents unauthorized access. This ensures that even if someone intercepts the data, they won’t be able to read or use it.
Why use a VPN
Increased privacy. With a VPN, users’ online activities are hidden from prying eyes, including ISPs, advertisers, and potential hackers. This is especially important when using public Wi-Fi networks, which are often less secure.
Bypassing geographic restrictions. Many online services and websites restrict content based on geographical location. With a VPN, you can create the impression that you are accessing the Internet from another country, allowing you to bypass these restrictions and access content freely.
Secure online transactions. For those who frequently make transactions or handle sensitive information online, a VPN provides an extra layer of security by ensuring the privacy of personal and financial data.
Choosing the right VPN
When choosing a VPN, you should consider factors such as speed, server location, and encryption level. It is also important to choose a VPN that adheres to a strict “no-logs” policy, which ensures that users’ online activities are not recorded or stored.
Free and paid VPNs
While there are many free VPN services available, they often have limitations in terms of speed, server locations, and security features. Paid VPNs, on the other hand, usually offer more features and better overall performance.
