What Is VPN?

Private Virtual Network

VPN is an acronym for Private Virtual Network.

The main purpose of a VPN is to provide you with security and privacy as you browse the internet.

To understand why the internet is insecure and why you need a VPN to secure it, you first understand the origin of the internet.

The internet was designed to send packets of information from one place to another as reliably as possible. At that time, the whole concept of networking was new, and the nodes often went down.

The designers designed the new network to route around failures rather than securing data (Who knew that securing data would be the top priority today).

Over the decades, some network applications have been able to secure themselves, but not all internet applications are secure. Many still send their data without any security or protection.

This is where internet users are left vulnerable to cyber criminals. They might intercept the connection and steal your valuable information.

That being said, when you use VPN, you create an encrypted tunnel around your connection. The idea is that everything you send using VPN is passed through an encrypted tunnel. All the data that passes through is protected with codes that can’t be deciphered.

If you are still not using a VPN while sending sensitive data, you are putting yourself at high risk. Click here to download a VPN application and share data securely.

How Does VPN Work?

Connecting to a VPN is very simple. After you have subscribed to a VPN service, you can simply open the software and click a button to connect. Once your data connection is established, here is how your data is transferred using a VPN server.

  • Once you are connected to the VPN server, wherever you share is shared through an encrypted tunnel.
  • The data goes through your ISP, but it has been scrambled. People can no longer decipher it.
  • Only a VPN server decrypts the encrypted data from your computer.
  • The data is then sent to the internet and waits for the reply.
  • The traffic is then encrypted using the VPN servers and is sent back.
  • The VPN on your device will decrypt the data so that you can understand.

How Are VPNs Used?

By now, you must know what VPN is and how it helps you protect your information. Now, we will cover the several advantages you can have using a VPN service.

1. Anonymity Online

When using a VPN software application, all your online movement is protected and encapsulated using encryption. Even if someone tries to track you, they will only encounter encrypted tracks that are confusing.

A VPN removes all the traces of your online activity and ensures you can browse through the internet wearing an invisibility cloak.

2. Secure Browsing On Public Network

Public networks are the best place to use free internet. However, at the same time, they are the riskiest network to connect to. As these networks are free, even a hacker can easily join the network connection and take advantage of it.

Connection to a public network using VPN ensures that your personal connection with the network is secure and protected from any external threats.

3. Protection Against Hackers & Government

A VPN scrambles your data using a string encryption method. This makes interpretation of your online activity almost impossible.

Why is this so important today? Well, there are different parties who will benefit from having your personal information. This also includes hackers and the government.

The security offered by VPN makes it a lot harder for third parties to look into your data for whatever reasons.

4. Fight Online Censorship

In many countries, some content is censored. These nations block a certain form of content. These include informational websites, applications, games, and other important things.

You can easily bypass online censorship using a VPN service. Using VPN, you can change your IP address to a country that allows accessing such content.

5. Bypass Geographical Restrictions

It is not just countries that impose restrictions. Sometimes, an online service also restricts its content to a certain region. This usually happens with a streaming site.

Using a VPN will allow you to connect the content bypassing the geographical restriction.

Is A VPN Safe?

While VPNs protect your data, it is important to ask: Are they safe?

Using VPN, you ensure that your digital footprint is deleted. However, the VPN company can see all your online movements. Therefore, it is crucial that you choose a trustable VPN that doesn’t keep any logs on their client and users.

You must know that many VPN services indulge themselves in shady business and sell their clients’ data for money. Keeping this in mind, you must check the authenticity of the VPN server before using it.

And one piece of advice – If it’s about sharing sensitive data using the internet, avoid using a FREE VPN. They are good for browsing and all but not for sharing data. For that, always go for paid services that take responsibility legally.
