What is a VPN (Virtual Private Network) and what is it for?
In recent years, increasing focus on online privacy and security has led many people to discover tools such as VPNs. With the increase in cyber threats and risks associated with surfing online, protecting one’s personal data has become a priority for many users.
One of the most effective solutions to guarantee security and privacy when accessing the Internet is to use a VPN, a service that protects data transmission on public networks and preserves one’s identity by detecting and rejecting malware, phishing and fraud attempts.
This tool allows you to surf the Internet anonymously, protecting your information from eavesdropping and malicious attacks. But what is a VPN and what makes it so useful?
What is a VPN and why is it important?
Are VPNs legal?
One of the most frequently asked questions concerns the legality of this tool: are VPNs legal? The answer depends on the country you are in. In general, the use of a VPN is legal in most countries, including the UK and Italy, but there are some exceptions. The key lies in the way the technology is used.
While using this type of connection to protect privacy and surf safely is perfectly legal, in some countries the use of a private network to circumvent certain government controls or to access prohibited content may be restricted.
What is a VPN for?
- Personal Data protection. A private network encrypts your Internet connection, making data, such as passwords and banking information, invisible to anyone trying to intercept them, especially on public or unsecured Wi-Fi networks.
- Online anonymity. By hiding your IP address, it allows you to surf without being tracked. This means that websites cannot collect information on your location or surfing habits, guaranteeing completely private surfing.
- Increased security. A VPN service protects online traffic from external attacks, such as hackers, and reduces the risk of unauthorised access. In addition, some private networks offer advanced features to protect against web threats, such as blocking suspicious applications in case of abnormal activity, malware and intrusive advertisements.
How does a VPN work?
A virtual private network protects your Internet connection by creating a channel through which data travels encrypted, preventing anyone from intercepting or monitoring it.
Here is how a VPN works in greater detail:
- User and server authentication. When you connect to a Virtual Private Network, your device is first authenticated by the server. This ensures that only authorised users can access the private network.
- Data encryption. Once authenticated, the server applies an encryption protocol to the data you send and receive. Encryption makes your data unintelligible to anyone attempting to intercept it, protecting your personal information during transmission. This creates a secure data exchange ‘tunnel’ that makes it impossible for third parties, hackers and even your service provider (ISP), to view the content passing over your connection.
- Encapsulation of data packets. Data is wrapped in an external packet, which is also encrypted. This encapsulation process makes it even more difficult for anyone to access the data, keeping it safe during transfer.
- Data decryption. Once data arrives at the destination server, the external packet is removed via a decryption process, allowing the data to be read securely.
Thus, a VPN works by creating a private and confidential connection between your device and the destination server, ensuring that your data can be transmitted encrypted and protected. Using an encrypted tunnel prevents data from being intercepted or used without your consent.

Protect your privacy online with one of the most comprehensive solutions.
VPN stands for Virtual Private Network. It is a technology that creates a private connection between your own device and the Internet. In practice, a VPN connection allows you to surf online more securely by masking your IP address and encrypting your data in transit. This means that your information is more difficult to intercept by third parties, such as hackers or individuals trying to monitor your online activity.
Using this type of connection is essential to ensure security and privacy, especially in situations where the risk of personal data exposure is high. For instance, when you connect to public Wi-Fi networks, such as those in bars, restaurants or airports, your data can easily be intercepted by malicious attackers who could connect to your device. By encrypting your connection, a Virtual Private Network prevents information from being stolen or monitored even on these public networks.
In addition, many organisations, including marketing agencies, try to monitor your behaviour as you browse in order to collect personal information, such as history and sensitive data. To protect your privacy and prevent your data from being used without your consent, it is essential to use a private network. In fact, using a VPN makes it almost impossible for anyone to monitor your online activities, ensuring that your information remains protected and out of reach of prying eyes.
