Hello, guys! Today I want to provide a more in-depth and detailed analysis of VPN technology. Stay with me if you like the topic.

You will learn the following information from my article:

OK, let's answer a bunch of these questions. Keep reading.

A VPN: what is it?

You may have already faceda VPN abbreviation on the Net. Actually, I think you've heard about it lots of times. But do you know exactly what is it and how does it work?

Let's see.

In a nutshell, VPN is a technology that provides withanonymity and security on the Internet.

But what is a VPN connection? Let's continue.

How does a VPN network work?

I won't describe the process in details. I will just give the basic information for you to catch the idea.

Let's say that you've already installed a provider on your device and connected the Net through it. Well, now your connectivity will be more secure, safe and even anonymous.


As soon as you connect to the Internet via a VPN, it creates a "secret tunnel" and all your personal information goes through it, making your IP invisible on the Net. It's cool, isn't it?

What does a VPN hide?

A VPN masks your IP. Itencrypts your data as well. It means nor your ISP or the government can see what you are doing on the Internet or when you were online.

Types of VPNs: what is a PPTP VPN?

There're lots of types of VPNs. A PPTP VPN is one of the most popular. PPTP is based on point to point tunneling protocol.It's widely used among private users and in organizations. It is not surprising, this type of a VPN is compatible with Windows, MacOS and Linux devices. The main disadvantage of PPTP VPNs is that they are don't use encoding.

There're lots of types of VPNs

That's why I highly recommend you to pay attention to other types of VPNs. It's better to choose the best type of a VPN before using this or that for a secure internet connection.

Every VPN service provides the information about the protocols it uses. You can check it on the official website of a VPN.

What is a VPN Kill Switch?

Another equally important aspect while choosing a VPN is a Kill Switch function. This feature is crucial as there is always a risk that your VPN connection will breakdown. This situation may lead to your sensitive data leakage, but a Kill Switch can successfully prevent this. It will stop your connectivity and ensure you that there are no possible Internet connections.

Why use a VPN: the main advantages

There're lots of pros, I should say. Let's focus on the most evident ones. OK, what is a VPN typically used for? Let's star.

There're lots of pros, I should say. Let's focus on the most evident ones

1. Security is crucial today. Even if you live in a free country where there is no strict Internet censorship, you may want to protect your sensitive data. It is extremely important today because the cases of data leakage are becoming more and more frequent today.

  • How does a VPN ensure anonymity?

It encrypts your data. Yes, a VPN not only masks an IP, it encrypts your data as well. That's why you need to know what protocol a VPN uses. The more robust a protocol of a VPN provider is, the more your data is protected.

2. The main reason why people use a VPN is, of course, to bypass geo-blocking. The authorities of some countriesadhere to advanced internet censorship system. For example, netizens in Chinahave to use a VPN to access restricted websites in their country. If you're going to travel to a certain country, first check if it is free or not. Not only social networks but also VOIP messengers are blockedin some countries.

  • How does a VPN unblock restricted websites?

Simple, it just hides your IP. Any VPN provider offers servers which are distributed all around the world. If you want to unblock, say Netflix, you need to choose a server which is located in the USA.

3.  There is hardly a person in the 21 century who doesn't like online shopping. It's vital to stay anonymous while booking a hotel or just buying something on the Internet. Many netizens use a VPN to find the cheapest plane tickets either.

  • How a VPN can help me to save money?

Online shops track our activity and every time we return to this or that website, the price on a certain thing may go up. What you need to do in this situation is to change your IP. The website will "think" that you are another person.

The list may go on and on. Let's go further if I've managed to catch your attention.
