What is a VPN connection? How does it work? Why would you use it?

What is a VPN?

VPN (Virtual Private Network) creates a secure connection between you and the Internet. When you connect to the Internet over a VPN, all of your data traffic is sent through an encrypted virtual tunnel. This has several advantages:

More and more people are using VPN while browsing the web. VPN stands for Virtual Private Network. It is a simple and effective solution that offers you three important things when you surf the Internet: more security, online privacy, and freedom. If you are not familiar with the concept of VPN, this can seem quite complicated. This page, we will explain exactly how a VPN works and why people use it. We’ll tell you everything you need to know about the benefits and capabilities of a VPN. We’ll also tell you about some great VPN providers that you can try for yourself.

How Does a VPN Work?

When you find a reliable and secure VPN provider, you can download and install their software. Then you select your preferred security settings and set up a secure connection to the desired VPN server. Connecting to a VPN is easy. When the connection is established, the following will happen to your data:

  1. The VPN software on your device will decrypt the data for you to understand and use.
  2. The encrypted data from your computer is decrypted by the VPN server.
  3. The traffic is then encrypted again by the VPN server and sent to you.
  4. The VPN server will send your data to the Internet and receive a response intended for you, the user.
  5. The VPN software on your computer encrypts your data traffic and sends it to the VPN server over a secure connection.
  6. VPN software will change your location.

A VPN connection will encrypt your data traffic, making it harder to intercept and view hackers and other parties. A secure connection also gives the user increased anonymity because Internet traffic is redirected through an external VPN server. As you browse websites through the IP address of the VPN server, your real IP address will remain hidden.

Usually, your location and even your identity can be revealed by your IP address, as it is unique to your internet connection. Using a different IP address (assigned to the VPN server), none of your Internet activity is tracked, allowing you to browse the web more anonymously.

The VPN application runs in the background on your computer, tablet or smartphone. You can access the internet as usual and you won’t notice anything fancy – except that you can bypass internet restrictions.

Why do I Need a VPN?

You might be wondering if you really need to use a VPN. An increasing part of our life is spent on the net. We do banking, keep in touch with friends, check our medical records and surf the Internet. It is important that all this information about you does not just get out on the street. After all, don’t leave bank accounts. If you don’t secure your internet connection, you may find that hackers, governments, your ISP, websites, your employer, and others are learning more about you than you would like. A VPN protects your data from all of these groups.

What is a VPN for? There are many reasons people start using VPNs. The largest can be summarized as follows:

  • VPN makes public Wi-Fi safer.
  • It increases your online privacy.
  • It provides you with more online security.
  • You can unblock sites which are banned by your government.
  • It allows you to browse the internet with more freedom.

VPN for Public Wi-Fi

If you use a public Wi-Fi network, you are an easy target for hackers. A public Wi-Fi hotspot is less secure than your private network. You don’t know who else is connecting to the network or who is setting it up. Hackers take advantage of the insecurity of public Wi-Fi networks and can steal your personal information. We recommend that you always use a VPN on free Wi-Fi hotspots.

The VPN sends its traffic through an encrypted tunnel. Encrypting your data makes it nearly impossible for anyone to view. This makes it very difficult for hackers, governments and your ISP to access your personal information.

Are vpns legal?

Are vpns legal

Some people wonder if it’s legal to use a VPN. After all, the service allows you to be much more anonymous online, which can be quite useful for hackers and online criminals. If such people cannot found online, they are still much more difficult to punish for crimes. However, this does not necessarily mean that using a VPN is prohibited by law.

On the contrary: many companies and officials work with VPN and recommend using it. The European Union also supports internet freedom that a VPN can give you.
Many countries find it completely legal to use a VPN. However, illegal activities, while using a VPN are still illegal. So using a VPN for everyday activities like web browsing, gaming, Netflix, and YouTube is not a problem at all. If you are using a VPN, for example, to download illegal files such as unofficial copies of movies and music. However, this is most likely against local laws. While a VPN gives you more anonymity on the Internet and makes it harder for officials to track you, the download itself is still illegal …

There are several countries that make it illegal to use a VPN. Using a VPN in most of the (Western) world won’t get you into any trouble.

VPN protocols

VPN networks use an encrypted connection, also called a tunnel. There are several ways (protocols) to configure such a VPN connection. These protocols ensure that your data remains secure and cannot read by others. Most common VPN protocols:

  • OpenVPN: OpenVPN is the most widely used VPN protocol. It is an open-source protocol that uses encryption based on the OpenSSL and SSLv3 / TLSv1 protocols. Most VPN services are compatible with OpenVPN and are available for many different platforms (e.g., Windows, Android, Linux, routers). Most consider OpenVPN to be the best option. The only drawback is that it doesn’t work on Mac OS and iOS, so you will have to use a different protocol for this (like IKEv2 / IPsec).
  • PPTP: PPTP (Point-to-Point Tunneling Protocol) was one of the first widely used protocols. This protocol contains some (potential) leaks. Therefore, its use is recommended only if speed is more important to you than safety. This might be the case if you want to bypass the restrictions imposed by streaming services.
  • IPsec/L2TP: The protocol combines IPsec for the encryption of data with L2TP for establishing a secure connection. Most operating systems include IPsec/L2TP, which is the right choice when OpenVPN isn’t available.
  • Softether: Softether, unlike the other VPN protocols mentioned above, is not a standalone protocol but an open-source application that runs on multiple platforms and offers VPN support for SSL VPN, L2TP / IPsec, OpenVPN, and Microsoft Secure Socket Tunneling … Protocol.
  • IKEv2/IPsec: IKEv2 is an IPSec based protocol. This protocol allows you to connect and switch between networks quickly. It makes it an ideal choice for smartphones, as these devices tend to change regularly between Wi-Fi networks and public Wi-Fi networks. According to some reports, IKEv2 is faster than OpenVPN. However, OpenVPN is considered the best protocol.
  • WireGuard: WireGuard is a relatively new protocol that is gaining popularity. It runs on the Linux kernel and should perform even better than OpenVPN and IPsec. It’s still in development, so you’d better use OpenVPN.

 Free vs. Paid VPNs: Which Should You Choose?

While paid VPNs are usually better, it’s hard to know if a free VPN is enough for you. It all comes down to your online hobbies and habits; you probably don’t have to pay to get what you need.

VPN FAQ ( frequently asked questions)

Does the VPN log user data?

The best VPNs only record the minimum user data necessary for their accounts to function. However, some allow you to create an anonymous profile with a unique email paid for with cryptocurrencies or gift cards. Of course, some VPNs record more than the minimum and are also in countries with data retention laws. Finally, most free VPNs try to register as much data as possible to sell that data to third parties.

Does a VPN hide your activity?

A VPN is probably the best way to hide your internet activity. Encrypts your traffic with military-grade encryption that is nearly impossible to crack. Also, a VPN hides your IP address from the government, your ISP, and other snoopers.

At the same time, there is no tool that can guarantee that your activity will remain hidden. If the government is really interested in you, it can do whatever it takes to locate you, although it won’t be easy. Therefore, if you are not a criminal or a revolutionary, you have nothing to worry about.

Is VPN safe for online banking?

Even without a VPN, online banking is relatively safe. However, you can make it even more secure by adding an extra layer of security. The VPN will encrypt your traffic and hide your IP address before it reaches the bank’s server, which means that it will be difficult for a third party to spy on you. It can be advantageous to connect to an insecure Wi-Fi network at a coffee shop or airport
