What Is a VPN? Myths, Legality, and How It Really Works

What is a VPN?

VPN is a service that hides your Internet Protocol (IP) address, allowing you to browse anonymously because no one can link your data to your IP.

To understand VPN's function, break down the three words “virtual,” “private,” and “network”:

VPN is “virtual” because it is a digital service; no cables or hardware are required.

VPN is “private” because it encrypts your connection, letting you browse without government, ISP, cyber‑criminals, or other observers seeing your activity.

VPN is a “network” because it creates a secure link between your device, the VPN server, and the Internet.

Is Using a VPN Illegal?

As of 2022, several countries/regions—including China, Iraq, North Korea, Russia, Turkey, Belarus, and Turkmenistan—have made VPN use illegal. Some, like Uganda, the United Arab Emirates (UAE), and Oman, partially block VPNs.

In most countries, such as the United States, Australia, the United Kingdom, and New Zealand, VPNs are 100 % legal.

Even where VPNs are legal, you cannot use them to commit crimes or hide illegal activity from law enforcement. A VPN is a safer browsing tool, not a license for cybercrime.

In fact, when using a VPN, you must understand several key truths.

VPN Cannot Protect Privacy

Many people think using a VPN hides their IP and protects privacy, but this is a misconception. First, the original purpose of VPNs was not privacy protection. Second, hiding the IP only shields you from third parties; the VPN provider can still see you. Finally, some providers collect user data, especially free VPN services.

VPN Is Just a Proxy

VPNs originated in 1996 to create temporary, secure links over public networks for accessing specific networks—typically for corporate use, such as accessing internal services from the public Internet.

Because the VPN client and server communicate through an encrypted tunnel, data transmitted cannot be intercepted or tampered with, which is crucial for protecting corporate confidential information.

When we use a VPN to access third‑party services, the VPN acts as a proxy: your request is first sent to the VPN server, which then accesses the target network on your behalf and returns the information.

Thus, using a VPN requires trusting the VPN provider, and from the provider’s perspective you have no privacy.

Choosing a Real and Reliable VPN Provider

Many companies and individuals use VPNs to bypass restrictions for overseas work. From a privacy standpoint, selecting a genuine and reliable VPN provider is essential. If possible, self‑hosting a VPN is best; governments usually allow self‑hosted VPNs for legitimate purposes after registration. Otherwise, choose a trustworthy VPN service.
