VPNs (Virtual Private Networks) | Their Work & Applications

Notably, VPNs are very important tools in our daily life. ExpressVPN is one of the best-known service providers in terms of VPNs. With solutions that are enabled for high speed, security & anonymity. No wonder, back in 2020, both TechRadar and CNET named the agency as their Editors’ Choice. In reality, your ISP usually sets up your connection when you connect to the internet.

And as a result, it tracks you via an IP address. Then, thereafter, your network traffic is routed through your ISP’s servers. Thus, it can log and display everything you do online. Of course, your ISP may seem trustworthy, but it may share your browsing history. Especially, with advertisers, the police or government, and/or any other related third parties.

What Are VPNs?

In addition, your ISPs can also fall victim to attacks by cybercriminals. And if they are hacked, your personal and private data can be compromised. This is especially important if you regularly connect to public Wi-Fi networks.

Unfortunately, you’ll never know who might be monitoring your internet traffic and what they might steal from you. Including passwords, personal data, payment information, or even your entire identity.

Under such circumstances, you should heavily rely on a dedicated VPN (like ExpressVPN ) to perform one or more tasks. It is clear to note, that the VPN itself should also be protected against compromise. So, what are VPNs, and how do they work?

What Are VPNs?

In general terms, VPNs are known as  “Virtual Private Networks.” They describe the opportunity to establish a protected network connection when using public networks. VPNs encrypt your internet traffic and disguise your online identity.

This makes it more difficult for third parties to track your activities online and steal data. The encryption takes place in real-time. A VPN protocol forms the foundation of a VPN service. Whilst, shaping every aspect of your experience.

On one side, consumers use VPNs to keep their online activity private and ensure access to sites and services that might otherwise be restricted. On the other side, companies use VPNs to connect far-flung employees as if they were all using the same local network at a central office. But, with fewer benefits for individuals than a personal VPN.

How does a VPN work?

A VPN works like a filter that turns all your data into “gibberish”. Even if someone were to get their hands on your data, it would be useless. Notably, as you connect to a secure VPN server, your internet traffic goes through an encrypted tunnel that nobody can see into. Including hackers, governments, and your internet service provider.

For instance, ExpressVPN encrypts your entire internet connection. So, in short, VPNs help hide your IP address by letting the network redirect it through a specially configured remote server run by a VPN host. Meaning, if you surf online with a VPN, the VPN server becomes the source of your data.

In other words, your Internet Service Provider (ISP) and other third parties cannot see which websites you visit. Or even what data you send and receive online. There are many different types of VPNs. But, you should definitely be familiar with the three main types.

The 3 main VPN types:
  1. SSL VPN
  2. Site-to-Site VPN
  3. Client-to-Server VPN

It is important to note that VPNs do not function like comprehensive anti-virus software. While they protect your IP and encrypt your internet history, a VPN connection does not protect your computer from outside intrusion. To do this, you should definitely use anti-virus software such as Kaspersky Internet Security. Why?

Simply, because using a VPN on its own does not protect you from Trojans, viruses, bots, or other malware. Once the malware has found its way onto your device, it can steal or damage your data. More so, whether you are running a VPN or not. It’s, therefore, important that you use a VPN together with a comprehensive anti-virus program to ensure maximum security.

What are the Benefits of a VPN Connection?

As I mentioned, protection is the first benefit you’ll get. A VPN connection disguises your data traffic online and protects it from external access. Bearing in mind, unencrypted data can be viewed by anyone who has network access and wants to see it.

With a VPN, hackers and cybercriminals can’t decipher this data. A VPN also helps secure encryption in terms of data. To read the data, you need an encryption key. Without one, it would take millions of years for a computer to decipher the code in the event of a brute force attack.

With the help of a VPN, your online activities are hidden even on public networks. And in terms of security, a secure VPN sends your internet traffic through an encrypted VPN tunnel. So that your passwords and confidential data stay safe. Even over public or untrusted Internet connections.

Also, by disguising your whereabouts, VPN servers essentially act as your proxies on the internet. Simply, because the demographic location data comes from a server in another country. Thus, your actual location cannot be determined.

In addition, most VPN services do not store logs of your activities. Some providers, on the other hand, record your behavior, but do not pass this information on to third parties. This means that any potential record of your user behavior remains permanently hidden.

Privacy is also key for they also keep your web browsing history private. VPN providers do not log user activity or share data with third parties. Their anonymous VPN service enables the Internet without surveillance. VPNs also provide secure data transfer too.

Meaning, if you work remotely, you may need to access important files on your company’s network. For security reasons, this kind of information requires a secure connection.

To gain access to the network, a VPN connection is often required. VPN services connect to private servers and use encryption methods to reduce the risk of data leakage. What about your freedom? Well, providers such as Norton have even created a special VPN like ProtonVPN.

In order to protect the journalists and activists who use ProtonMail. Likewise, ProtonVPN breaks down the barriers of Internet Censorship too. Allowing you to access any website or content. Below, let’s look at the main features you should expect from such a comprehensive VPN solution provider.

The key features of a good VPN service include:

  • Encryption of your IP address: The primary job of a VPN is to hide your IP address from your ISP and other third parties. This allows you to easily send and receive information online. Without the risk of anyone but you and the VPN provider seeing it.
  • Encryption of protocols: A VPN should also prevent you from leaving traces, for example, in the form of your internet history, search history, and cookies. The encryption of cookies is especially important because it prevents third parties from gaining access to confidential information such as personal data, financial information, and other content on websites.
  • Kill switch: If your VPN connection is suddenly interrupted, your secure connection will also be interrupted. A good VPN can detect this sudden downtime and terminate preselected programs, reducing the likelihood that data is compromised.
  • Two-factor authentication: By using a variety of authentication methods, a strong VPN checks everyone who tries to log in. For example, you might be prompted to enter a password, after which a code is sent to your mobile device. This makes it difficult for uninvited third parties to access your secure connection.

There are now also many providers of VPN connections for smartphones that keep mobile data traffic anonymous. You can find certified providers in the Google Play Store or the iOS App Store. However, remember that only your data traffic on the internet is anonymized and protected by using a VPN.


It’s important to realize, a VPN server can also allow access to regional content. Not to mention, regional web content is not always accessible from everywhere. That’s why websites often contain content that can only be accessed from certain parts of the world.

Basically, standard connections use local servers in the country to determine your location. This means that you cannot access the content at home while traveling. While at the same time, you cannot access international content from home.

Fortunately, a VPN lets you fake your location, providing you with access to otherwise restricted content. This means if you travel abroad you can still connect to your usual home streaming services, websites, and apps.

Equally important, with VPN location spoofing, you can switch to a server from another country and effectively “change” your location. In particular, they encrypt your internet traffic and hide your real IP address and location.

When it comes to customization, most providers use the same off-the-shelf protocols. But now, ExpressVPN provider has engineered its own: Lightway VPN Protocol. Not to mention, Lightway uses wolfSSL — a well-established cryptography library that has been extensively vetted by third parties.

In other words, VPNs are the easiest and most effective way for people to protect their internet traffic. As well as keep their identities private online. Learn how to connect to a VPN in Windows 10 by Microsoft.
