How Does a VPN Work? All You Need to Know About VPNs

It seems like nearly everybody these days utilizes a VPN to unblock websites and safeguard their internet-based privacy. Yet, what precisely are VPNs and how do they work? (VPN for privacy protection)

Virtual private networks (VPNs) have become synonymous with Internet security. VPNs help keep your passwords and other important personal data away from intrusive eyes by directing your Internet traffic through a secure server. This functionality has also made VPNs useful for unblocking restricted content, browsing the web anonymously, torrenting safely, and so on.

However, a VPN is significantly more than simply a connection to a distant server. So read on as we delve into VPNs, how they work, and what you should look for while choosing your next VPN provider.

What is a VPN?

A VPN is a service that conceals your Internet Protocol (IP) address. This allows you to browse the Internet anonymously since no one can associate your data with your IP address.

To comprehend what a VPN does, you simply need to break down the words "virtual," "private," and "network":

  • VPNs are "virtual" because they are a digital service. You needn't bother with a cable or hardware to utilize them.
  • VPNs are "private" because they encrypt your connection and permit you to browse the Internet without states, Internet Service Providers (ISPs), cybercriminals, and other curious individuals spying on you.
  • VPNs are "networks" because they create a secure connection between your device, the VPN server, and the Internet.

Brief History of VPNs

According to security.org's VPN Consumer Use, Adoption, and Purchase Study, 85% of Internet users above 18 years old know what a VPN is. This represents an increase of 13% compared to 2020.

However, VPNs were not always so well-known. Researchers first realized that the world needed VPNs after the launch of the Advanced Research Projects Agency Network (ARPANET), developed by the US Department of Defense, which was an early version of the Internet.

ARPANET prompted the creation of the Transfer Control Protocol/Internet Protocol (TCP/IP), allowing devices and local networks to connect over a shared network. This introduced a cybersecurity threat, since a third party could use the network to access the devices within.

Researchers at AT&T Bell Laboratories and Columbia University developed the first VPN, the Software IP Encryption Protocol (swIPe), in 1993. Wei Xu and Gurdeep Singh-Pall further developed VPN technology in 1994 and 1996, respectively. Xu created IPSec, and Singh-Pall (a Microsoft employee) created the Point-to-Point Tunneling Protocol (PPTP).

In the early 2000s, VPNs were used by many corporations and governments, and consumers began adopting them later during the 2010s. (VPN for all devices)

Uses of VPNs

VPNs are useful for people who want to:

  • Utilize WiFi in a public area that is vulnerable to hacking or spoofing (such as airports, cafes, and coworking spaces)
  • Browse the Internet anonymously
  • Avoid targeted ads
  • Hide your ISP data
  • Get better deals on flights, hotels, major purchases, etc.
  • Avoid censorship or government surveillance
  • Access websites and content with geographic restrictions
  • Protect yourself from viruses, ransomware, worms, and Trojans

The three most common reasons people used a VPN were "for general security" (55%), "for general privacy" (54%), and "to access secure networks for my work" (41%). https://purervpn.com/

Is it Legal to Use a VPN?

As of the beginning of 2022, some countries have made it illegal to use a VPN, including China, Iraq, North Korea, Russia, Turkey, Belarus, and Turkmenistan. Some countries partially block VPNs, including Uganda, the United Arab Emirates (UAE), and Oman.

However, VPNs are 100 percent legal in most countries, including the United States, Australia, the United Kingdom, and New Zealand.

Although VPNs are legal in many places, you cannot use them to commit crimes or hide your online activity from law enforcement. VPNs are a service for safer Internet browsing, not a license to commit cybercrimes.

Additionally, using a VPN might violate the Terms of Service (ToS) of streaming services like Netflix and Hulu. If a streaming service detects you browsing through a VPN, it may cancel your subscription or ban you from the platform.

Streaming services have cracked down on the use of VPNs because it violates their licensing agreements with content providers. These licensing agreements are usually country-specific, so when you watch content from different countries, Netflix is technically violating its contract.

Since the agreement is between the content provider and the streaming platform, the content provider could hold the streaming service liable for showing you the content. next blog
