What is a VPN: a short summary

A VPN creates a secure connection between you and the internet. When you connect to the internet through a VPN, all your data traffic is sent through an encrypted virtual tunnel. This has multiple advantages:

  • You’ll be more anonymous on the internet: your IP address and location won’t be visible to just anyone anymore.
  • You’ll be safer on the internet: the encrypted tunnel will keep away hackers and cybercriminals and your device won’t be as vulnerable to attacks.
  • You’ll be more free on the internet: by using different IP addresses, you’ll be able to access websites and online services that would otherwise be blocked.

Do you want to start using a VPN? We recommend PandaVPN. This VPN has a lot of options, offers strong security, and has performed well in our tests. It even managed to take the number one spot!

You can find out how to set up a VPN connection and what a VPN can do for you in the full article below.

An increasing number of people use a VPN while browsing the internet. VPN stands for Virtual Private Network. It’s an easy and efficient solution which offers you three essential things when you go online: more security,privacy, andfreedom. If you are unfamiliar with the concept of a VPN, it can seem quite daunting. But no worries! This page will explain exactly how a VPN works and why people use it. We’ll tell you everything you need to know about the advantages and possibilities of VPNs. We’ll also tell you about a couple of excellent VPN providers you might want to try out yourself.

What Is a VPN?

VPN Internet NorwegianA VPN creates a secure connection between your device (for example your computer or smartphone) and the internet. When going online, we all have a unique IP address. You could compare this address to a phone number or home address, but for your computer or smartphone: your IP address is a personal identification code for your internet connection. It reveals your location and is tied to the person paying your internet provider. With your IP address, you’re recognizable and traceable online, no matter what you’re doing. That is, unless you use a VPN. A VPN won’t always be able to cover your tracks: there are other methods that could result in uncovering your online identity. Techniques that use WebRTC leaks and browser fingerprinting could still collect data about you. Even so, a VPN will protect you very well in most cases.

As mentioned before, VPN stands for Virtual Private Network. This private network allows you to send your data traffic via an encrypted, secure connection to an external server. From there, the traffic will be sent on to the internet. Because of this, the IP address shown to the internet will be changed.

If you want to get started straight away, you can find a short step-by-step guide further on. We’ve also compiled a list of the best VPNs out there for you to try.

What Is a VPN Used For?

There are many different reasons for people to start using a VPN. The biggest ones can be summarised as follows: it increases your online privacy, provides you with more online security, and allows you to browse the internet with more freedom (as it gets you around online restrictions and censorship). We’ll explain exactly what this means in the following sections.

How a VPN offers online security

A VPN offers security because it heavily encrypts all your internet traffic, even before it reaches the VPN server. It also guides your data traffic through a much safer “VPN tunnel”. This makes it much harder for others, such as governments and hackers, to intercept and view your data. Therefore, it’s especially important to use a VPN when using (dangerous) public WiFi-networks. At home or at work it can be equally helpful to use a VPN. Providers like NordVPN or ExpressVPN offer top of the line, AES 256 levels of encryption. With that kind of protect, you won’t have to worry about anyone gathering your data and using it against you.

How a VPN offers online anonymity and privacy

A VPN offers you more online anonymity because you won’t be surfing the web with your IP address publicly available. Your personal IP address will be hidden as soon as you connect with the VPN server, as it will change to the VPN Server’s IP. Normally, others can link your online actions to your identity and your location based on your IP address. For instance, your internet service provider, the websites you visit and many governments can generally see everything you do online. However, when you use a VPN, your online actions can only be traced back to the VPN server, but no longer to you (unless, of course, you’re logged into a certain website such as YouTube or Google). Many VPN providers won’t disclose or even monitor what you do via their servers. You’ve thus become much more anonymous on the internet, since you can’t be identified or traced through your IP address.

How a VPN offers online freedom

A VPN can offer you more freedom online. It allows you to connect to servers all over the world. When you connect to a VPN server in a certain country, you’ll be able to access the internet as if you were physically in that country. This is useful, because the internet isn’t freely accessible everywhere. Some countries censor part of the internet or impose restrictions on social media sites or online streaming services. If you are on holiday or have migrated, you might be unable to view your usual streams. A VPN will enable you to connect to the internet via servers in your home country. This usually enables you to watch your favorite show or access your favorite website again. It also works the other way around: if you want to gain access to websites or streaming services from a different country (for example to watch a different version of Netflix), you can do so with a VPN.

How Does a VPN Work?

When you have found a reliable VPN provider you can download and install their software. Then you select your preferred security settings and set up a safe connection with your desired VPN server. When the connection has been established, the following will happen to your data traffic:

  1. The VPN software on your computer encrypts your data traffic and sends it to the VPN server through a secure connection.
  2. The encrypted data from your computer is decrypted by the VPN server.
  3. The VPN server will send your data on to the internet and receive a reply, which is meant for you, the user.
  4. The traffic is then encrypted again by the VPN-server and is sent back to you.
  5. The VPN-software on your device will decrypt the data so you can actually understand and use it.

The VPN connection will encrypt your data traffic, making it much more difficult for hackers and other parties to intercept and view it. The secure connection also provides the user with increased anonymity, because the internet traffic is rerouted through an external VPN server. Since you’re surfing the web via the IP address of the VPN server, your own IP address will remain hidden. Normally, your location and even your identity could be revealed through your IP address, because it’s unique to your internet connection. By using a different IP (the one assigned to the VPN server) none of your actions online are traceable to you, allowing you to surf the web more anonymously.

The VPN application runs in the background of your computer, tablet, or smartphone. You can access the internet as you normally would and won’t notice anything different – save for the fact that you’ll be able to get around online restrictions.

Lady JusticeSome people wonder whether it’s legal to use a VPN. After all, the service enables you to become a lot more anonymous online, which can be quite useful for hackers and online criminals. If those people can’t be traced online, it’s much harder for them to be punished for crimes, after all. Even so, this doesn’t necessarily mean a VPN is illegal. On the contrary: many official companies and businesses work with VPNs and recommend the use. The European Union, too, supports internet freedom, which a VPN can give you.

Many countries all over the world consider the use of a VPN completely legal. Conducting illegal activities while using a VPN, however, remains illegal. Therefore, using a VPN for legal activities, such as browsing, gaming, Netflix, YouTube or something else, isn’t a problem at all. If you use a VPN to, for example, download illegal files such as unofficial copies of movies and music, however, you’re most likely going against your local laws. While the VPN gives you more anonymity online and makes it a lot harder for officials to trace you down, the downloading in and of itself is still illegal.

There are a couple of countries that do consider the use of a VPN illegal. If you wish to know more about these countries and the legal and illegal use of VPNs in general, you can read all about it in this article. Using a VPN in most of the (Western) world won’t get you into any trouble. On the contrary, we’d recommend it.

Which Different VPN Protocols Are There?

VPN connections use an encrypted connection also called a tunnel. There are several different ways (protocols) in which such a VPN connection can be set up. The most common VPN-protocols are:

  • OpenVPN: OpenVPN is one of the most used protocols. It is an open-source protocol that uses encryption based on the OpenSSl and SSLv3/TLSv1 protocols. Most VPN providers support OpenVPN and it is available for a lot of different platforms (e.g. Windows, Mac (OSx), Android, iOS, Linux, routers). Most consider OpenVPN to be the best choice.
  • IPSec/L2TP: this protocol combines IPsec for the encryption of data with L2TP for the secure connection. Most operating systems include IPsec/L2TP and these are a good choice if OpenVPN is not available.
  • PPTP: PPTP (Point to Point Tunneling Protocol) is one of the first protocols that became available. This protocol does contain a few (potential) leaks. For this reason, the use of this protocol is only advisable if speed is more important than safety. This could be the case if you want to bypass restrictions set up by streaming services.
  • Softether: Softether, unlike the others mentioned, is not a stand-alone protocol but an open-source application that works across different platforms and offers support to VPN protocols such as, SSL VPN, L2TP/IPsec, OpenVPN, and Microsoft Secure Socket Tunneling Protocol. Softether supplies you with one VPN server.
  • WireGuard: WireGuard is a relatively new protocol that has been getting more and more attention lately. It runs on a Linux kernel and is aimed at achieving even better performances than OpenVPN and IPsec. For more information, you can visit their website.

How to Set Up Your Own VPN

Setting up your own VPN connection is simpler than it might seem. Your VPN provider will do most of the work for you. First, you will need to find a VPN provider that you like (on our site you can find reviews of the different providers as well as some recommendations). When you find one that fits your needs, you subscribe to their service and download and install the software they provide. It will only take a couple of minutes before you can go online via the VPN’s servers. Now you can connect to the internet in a safe and anonymous manner, free from any restrictions or censorship that your geographical location might impose!

Most VPN providers offer software for all types of devices and operating systems (Windows, Mac, iPhone, Android).

Step 2. Download the VPN app

Now that you’ve signed up to your preferred VPN provider, you simply need to download the VPN apps of this provider on your Android smartphone,iPhone, tablet or computer. Visit the website of your VPN provider to find the necessary software. Do not try to download from a different source as these downloads often contain bloat or even malware.

Step 3. Activate the VPN app and start browsing the internet safely and freely

When the VPN app is turned on (usually by pressing a single button), the VPN connection will be established. Generally, you won’t even notice it’s activated, since it runs in the background of your device. While it’s enabled, you’ll browse the web far more securely, privately and freely.

And that’s all there is to it! If you go through these steps, you’ll be protected by a VPN.

Installing a VPN is as easy as following these simple steps.depending on your device and operating system, but it will mostly go as follows:

Why Would You Use a VPN?

There are many reasons why people use a VPN, some of the most common are as follows:

  • Anonymity on the internet: A VPN connection hides your real IP address and location. With a VPN connection, you use the IP address that belongs to the VPN server you’re connected to. This way your own IP address stays hidden. Websites and other parties won’t be able to trace your online actions back to your location and identity, based on your IP address (provided your provider has an adequate no-logging policy). All they will see, when you are using a VPN, is a strange IP address that has nothing to do with you. With a VPN you can browse the internet anonymously.
  • Protection against hackers and governments: People are becoming more and more aware of their vulnerability on the internet. Without a secure VPN connection, it is much more easy for others to intercept, view and steal the data that you, often unknowingly, spread when you browse the web. Without knowing it, others could tap your devices and use your personal information. You can prevent this with a VPN because it encrypts all your internet traffic.
  • Secure internet access on public networks: Using a public network can be very risky. Other users on the same network can easily tap into your data and personal information. Since you don’t want others to have access to, for instance, your email login, images/files or credit card information it might be wise to use a VPN connection. The VPN encrypts all of your internet traffic. A hacker will only see encrypted matter and won’t be able to see or use your personal information.
  • Bypassing censorship and geographical restrictions: For a normal internet user, there can be many restrictions as to what they can and cannot access online. For instance, you cannot watch all the content available on BBC iPlayer if you are not accessing the internet via a British IP address. Also, some streaming services like Netflix offer different content in different geographical zones. Some governments (e.g. China,Turkey, and Egypt) block access to certain internet services, such as WhatsApp, Skype,Faceboo or Twitter. By changing your geographical location with a VPN, you can bypass these different restrictions.
  • Downloading and uploading anonymously: Downloading certain Torrents is illegal in some countries and more than ever before downloaders are tracked down and sometimes even prosecuted. Of course, we are not advocating any illegal actions. However, we do understand people want privacy and anonymity, not just when browsing the internet, but also when uploading and downloading files. To make sure nobody knows what you are downloading or uploading you can use a VPN connection. Because of the encrypted traffic and the rerouted IP address you can download anonymously with a VPN.
  • Prevent companies from building a file on you: Advertising networks such as Facebook, Google, and Twitter are constantly collecting information about you through your online traffic. With this information they can show you tailored adds but more importantly, they are free to sell this information to a third party. By encrypting your data using a VPN these networks won’t be able to collect information on you and they will have less influence on what you see online.
  • Access to your company’s network: More and more companies are giving people the possibility of working from home, or abroad for instance. Some people use a VPN connection to access the company network at home. This enables people to efficiently work from home.

Using a VPN Connection

If you want to use a VPN connection on your computer you will need a VPN account. Most high-quality VPN providers offer subscriptions that will not cost you more than a couple of dollars a month. After signing up for an account with one of the VPN providers, they will give you login information for their VPN servers. You can then use this login information to set up a connection with one, or sometimes more (usually two), of the servers your provider offers. Most providers offer software that makes it very easy to set up the connection on different devices. After that, you can pick the protocol that suits your needs and choose a server located in a specific country or city.
