What is VPN? Are VPNs legal to use?

A Virtual Private Network, or VPN, stands as a crucial technology for securing personal information when navigating the online landscape. This article aims to explain “what is VPN” and how it operates to establish a secure data channel between users and the Internet. Additionally, we will delve into the legality of VPN usage, particularly in countries with strict regulations concerning this technology.

What is VPN?

A virtual private network (VPN) is a service designed to enhance online privacy by encrypting the communication between your device and the internet. This encryption establishes a secure connection, creating a private tunnel through which your data and communications can travel while using public networks.

But what is the purpose of VPNs? In essence, VPNs safeguard your online privacy to prevent potential targeting by hackers or discrimination based on your location. While VPNs were once considered innovative technological solutions, they have now become indispensable tools.

If the concept of a VPN is still unclear, you can think of the internet as a vast highway that we navigate on motorcycles. We visit our preferred destinations (websites), make purchases in online shops, manage our stock portfolios, read the latest news, engage in gaming, and more.

When riding a motorcycle on this highway, you are completely exposed. Anyone can peer into your digital life along these roads. Your identity, online activities, and more are easily visible. Moreover, you can be tracked back to your home; you are traceable.

By using a virtual private network, instead of riding openly on the vast internet highway, you opt for a private tunnel. A VPN serves as your personal tunnel, enveloping you in anonymity and preventing others from observing your online movements or activities.

To step away from the metaphor and delve into a bit more technical detail: a VPN encrypts your network connection and conceals your IP address.

How does a VPN work?

A VPN operates by concealing your IP address, directing it through a specially configured remote server managed by a VPN host. Consequently, when you browse the internet using a VPN, the VPN server serves as the origin of your data. This ensures that your Internet Service Provider (ISP) and other third parties cannot observe the websites you visit or the data you transmit and receive online. Essentially, a VPN functions as a filter, transforming all your data into unintelligible “gibberish.” Even if someone were to access your data, it would be rendered useless.

What advantages does a VPN connection offer? A VPN connection masks your online data traffic, safeguarding it from external intrusion. Unencrypted data is susceptible to viewing by anyone with network access. With a VPN, hackers and cybercriminals are unable to decipher this data.

Robust encryption: To interpret the data, an encryption key is essential. Without it, a computer would require millions of years to decode the code in the event of a brute force attack. With a VPN, your online activities remain concealed even on public networks.

Concealing your location: VPN servers act as proxies on the internet, obscuring your actual location since demographic location data originates from a server in another country. Moreover, most VPN services do not retain logs of your activities. While some providers may record your behavior, they refrain from sharing this information with third parties. This ensures that any potential record of your user behavior remains permanently hidden.

Access to regional content: Regional web content may not always be accessible universally. Services and websites often feature content exclusive to specific parts of the world. Standard connections rely on local servers in the country to ascertain your location, restricting access to content when traveling or attempting to reach international content from home. VPN location spoofing enables you to switch to a server in another country, effectively “altering” your location.

Secure data transfer: If you work remotely and need access to crucial files on your company’s network, a secure connection is imperative. VPN connections are often mandatory to gain entry to the network. VPN services connect to private servers and employ encryption methods to mitigate the risk of data leakage.

Why should you use a VPN connection?

When you access the internet, your connection is typically established by your Internet Service Provider (ISP), which identifies you through an IP address. All your online activities pass through your ISP’s servers, enabling them to record and monitor your online behavior.

While your ISP may appear reliable, it could share your browsing history with advertisers, law enforcement, government agencies, or other external entities. Additionally, ISPs are susceptible to cyber attacks, and if breached, your personal and private information may be at risk.

This becomes particularly crucial when connecting to public Wi-Fi networks, where your internet traffic might be monitored by unknown entities seeking to steal passwords, personal data, payment details, or even your entire identity.

What functionalities should an effective VPN possess?

A dependable VPN should fulfill various tasks while also ensuring its own protection against compromise. The following are essential features to anticipate in a comprehensive VPN solution:

  1. Concealment of IP address: The primary function of a VPN is to shield your IP address from your ISP and other third parties, allowing you to transmit and receive information online without the risk of unauthorized access.
  2. Protocol encryption: A VPN must safeguard against leaving traces, such as internet history, search records, and cookies. Notably, encrypting cookies is crucial to prevent third parties from accessing sensitive information like personal data and financial details on websites.
  3. Kill switch: In the event of an abrupt VPN connection interruption, a reliable VPN can detect this downtime and terminate preselected programs. This minimizes the chances of compromising data during such interruptions.
  4. Two-factor authentication: A robust VPN employs diverse authentication methods to verify any login attempts. For instance, users may be required to enter a password, followed by a code sent to their mobile device. This multi-step authentication makes it challenging for unauthorized third parties to gain access to your secure connection.

Different types of VPN

VPN comes in two primary forms. One variant is the remote-access VPN, enabling users to establish a connection with another network, whether it’s the internet or their company’s internal system, using a secure encryption tunnel. The second variant is the site-to-site VPN, also known as a router-to-router VPN, primarily employed in corporate settings, especially when an enterprise has multiple headquarters. The site-to-site VPN establishes a closed internal network, forming an intranet where various locations can interconnect.

VPNs are generally categorized into these two types, and there are specialized VPNs within these categories tailored for specific purposes, such as a P2P VPN server designed for file sharing and downloading.

Various VPN protocols exist, each offering different security methods. The oldest among them is PPTP (Point-to-Point Tunneling Protocol), which, although still in use, is widely regarded as one of the least secure options. Other protocols include IKEv2, L2TP/IPSec, SSL, TLS, SSH, Wireguard, and OpenVPN. OpenVPN, being an open-source protocol, is considered highly secure, as any vulnerabilities in its programming are quickly identified and patched.

How much does a VPN cost?

The cost of a VPN is determined by the duration of your commitment to a specific VPN provider. The longer your commitment, the greater the potential savings in the long term. Nowadays, many VPN providers present options such as annual, biennial, triennial, or even lifetime subscription plans. Nevertheless, considering the dynamic nature of the VPN market, we advise against opting for plans extending beyond two years. If you opt for an annual or multi-year plan, your monthly cost could range from approximately $2 to $10, depending on the provider. If you choose a monthly plan, expect to pay around $10 to $15 per month. Select the option that aligns with your needs and budget, but bear in mind that a higher price tag does not necessarily guarantee superior quality.

We strongly discourage the use of free VPNs. There’s a significant likelihood that they might compromise your data by selling it to advertisers and third parties, undermining the very purpose of having a VPN. Some free VPNs have been reported to inject users’ devices with malware, posing a direct threat. Even if not every free VPN has such issues, most are likely to have limitations in terms of server locations, data allowance, speed, unblocking capabilities, features, etc.

Considering the affordability of many VPN services, it is advisable to invest in a premium VPN product, acquiring a comprehensive package for just a few dollars per month.

Are VPNs legal to use?

In the majority of countries, using VPNs is completely legal. Safeguarding your online privacy is a legitimate concern, and using a VPN for this purpose should not pose any legal risks. However, it’s important to note that there are countries, such as China, Iran, Oman, Russia, Turkmenistan, the UAE, and Belarus, where the use of VPNs is either prohibited or considered illegal. If you use a VPN in one of these countries, you may face legal consequences if discovered. Interestingly, these are also the places that impose restrictions on certain applications and platforms, making VPNs the only means to access them. Consequently, in such locations, only VPNs with obfuscated servers can effectively secure your online data by disguising VPN traffic as regular HTTPS traffic.

Nonetheless, in the majority of the world, VPNs are entirely legal, and you won’t encounter legal issues simply for utilizing one. It’s crucial to bear in mind, however, that engaging in illicit online activities remains illegal, irrespective of whether a VPN is used.

Conclusion

In conclusion, a VPN not only serves as a robust network security tool but also guarantees online privacy for users. The article has provided an overview of “what is VPN” and its significance in today’s digital age. Through this exploration, we gain a better understanding of the global legality of VPN usage and an awareness of the challenges that may arise in an increasingly complex online environment.
