What is VPN? Definition for Dummies!

VPN Definition

A Virtual Private Network (VPN) guarantees your privacy and anonymity on the Internet by creating a private network with a public Internet connection. VPNs mask your Internet Protocol (IP) address so that your online activities are virtually untraceable. More importantly, VPN services establish secure and encrypted connections to provide more privacy than a secure Wi-Fi hotspot.

VPN simple definition and explanation

A VPN, or virtual private network, is a secure tunnel between your device and the internet. VPNs protect you from spyware, interference, and censorship.

VPN is the easiest and most effective way to protect your internet traffic and keep your personal information private. When you connect to a secure VPN server, your internet traffic travels through an encrypted tunnel that no one sees, including hackers, governments, and your ISP.

The general public uses VPNs to maintain their online privacy and unblock access to websites and services that might otherwise be restricted.

Businesses use VPNs to connect employees who work remotely as if they were all using the same local area network in the office, but with less benefit to the individual than a personal VPN.

Why do you need a VPN?

Nobody likes to be tracked and observed – even if they have nothing to hide. This is why you need the right tool. Here are some other reasons you might need a VPN:

Youregularly use public Wi-Fi

By definition, a VPN is your best friend when you use public Wi-Fi. Hackers have many ways to steal your data from shared hotspots, but using a VPN means you don’t have to worry anymore. Hence, people who want to browse in confidence should use a VPN to secure their connection.

You need to hide your location

People who work in countries with restricted freedom of expression hope to have a private Internet connection for their work. Sometimes their life can depend on it. Anyone living in an authoritarian regime should use a VPN to mask their IP address and provide additional security for their confidential messages.

You want to access blocked content

One of the most popular things a VPN is used for is access to content. If using streaming services and social media abroad is important to you, a VPN can help. It changes your IP address and redirects your internet connection through a remote server.

You don’t want to be followed and monitored

Government agencies track and collect your opinions, messages, social media posts, and other private information. The VPN protects you from this by encrypting your data traffic and masking your IP address. Use it at home, at work and on the go for continuous protection.

You are an online gamer

People who like to play online have to deal with DDoS attacks, bandwidth restrictions, and content restrictions. Fortunately, you can forget about all of these problems with a VPN. If you are serious about gaming and want to enjoy a stable and secure connection, consider using a VPN.

You want to encrypt your data

Using a VPN is a good idea even if you are browsing at home.

VPN encryption is important if you want to protect your internet traffic and minimize your digital footprint. As a result, your ISP cannot sell all of your browsing history to the highest bidder.

How does a VPN work?

When you download the VPN software to your device, it does most of the work for you, all you need to do is identify yourself and sign in.

However, knowing how a VPN works does help to better understand the service. Here’s what’s going on behind the scenes:

  1. When you connect to a VPN, your client is authenticated through a VPN server.
  2. The server then applies the encryption protocol to all data that you send and receive.
  3. The VPN service creates an encrypted “tunnel” over the Internet. It provides data that travels between you and your destination.
  4. To ensure the security of each data packet, the VPN wraps it in an external packet, which is then encapsulated. It is the main element of a VPN tunnel that ensures the security of data in transit.
  5. When the data arrives at the server, the external packet is discarded during decryption.

The technology behind VPNs is complex, but their use is not. Read on to learn how to set up a VPN on your devices.

The VPN glossary

Here are some basic VPN concepts to help you understand how a VPN works and the benefits it offers:

Deputy

The VPN server acts as a proxy server : instead of your real IP address and the location you are visiting, only the IP address and the location of the VPN server are displayed.

It makes you more anonymous online.

Authentication

Establishing a secure connection is a tricky problem that is solved by math in a process called authentication.

Once authenticated, the VPN client and the VPN server can be sure that they are communicating with each other and with no one else.

Tunneling

The VPN protects the connection between client and server through tunneling and encryption.

Tunneling is the process in which each data packet is enclosed in a different data packet . This makes reading difficult for others during transport.

Encryption

The data inside the tunnel is also encrypted so that only the specified recipient can decrypt it. This makes the content of your internet traffic completely private. Even your ISP won’t see it.

VPN protocols

VPN protocols are like a series of instructions . VPN providers use them to ensure that users can securely connect to their service. There are many VPN protocols available, each with their advantages and drawbacks.

The most popular VPN protocols today include:

  • IKEv2
  • OpenVPN
  • L2TP / IPsec
  • SSTP
  • PPTP
  • Wire protection

  2. Your device is now in a VPN and your IP address can be changed to the IP address provided by the VPN server.
  3. You are now free to use the internet as you wish as the VPN protects all of your personal data.
