What Is a VPN? | A Simple Guide to VPNs in 2022

A VPN (Virtual Private Network) is a piece of software made to protect your privacy and safety online. A VPN functions by making a secure tunnel where your data passes through to get to its server. Once your data is on the VPNs server, the VPN will encrypt it and send it to its destination. While this may seem like a simple process, there’s an abundance of benefits to be gained from it, such as online anonymity, safely connecting to public Wi-Fi, and hiding your location from advertisers.

Although VPN technologies are quite common today, many of us aren’t sure what a VPN is exactly, and why we would use one. In this article, we’ll answer those questions, as well as what the best all-round VPN is, and how you can install it. In case you’re just here for that last one, ExpressVPN is the best VPN in our testing. It provides ample security, speed, and customization, all wrapped up in a user-friendly package. It even has a 30-day money-back guarantee for you to try it out risk-free!


What Is a VPN? | How Does a VPN Work?

A VPN is a service designed to help you maintain your privacy and security online. A VPN uses encryption technologies in order to encrypt all the data sent to its server before it forwards it to its indented location. This is how VPNs hide your data like your IP, and how they bypass geo-locks. While this might seem narrow, there are quite a few areas where a VPN is irreplaceable in ensuring that your data stays protected. In some countries like China, a VPN might even be the only way to reach the Western side of the internet.

Now, let’s take a look at one of the most important building blocks of any VPN- encryption protocols.

Encryption Protocols

A VPN’s encryption protocol is the process it uses in order to secure an encrypted path between you and the server. This works by taking the data you send the VPN, and then encrypting it by using a mathematical algorithm. This, in turn, hides the data you’ve sent from anyone that doesn’t have the encryption key. Although there are many encryption protocols out there, all with their own pros and cons, we’ll mainly be looking at the three most popular ones: OpenVPN, IKEv2, and WireGuard.

OpenVPN | The Most Secure VPN Protocol

OpenVPN is an over 20-year-old VPN encryption protocol and is available in most commercially available VPNs today. It owes its success to its incredible security and long history of success in keeping security purists happy. It’s one of the easiest protocols to configure manually, being that OpenVPN is completely open-source. This protocol supports 5 different kinds of encryption algorithms- AES-128, AES-256, Blowfish, ChaCha20, and Camellia. The two most secure ones out of those for general-purpose use are AES-128 and AES-256.

Tried and tested for the last two decades

The AES, or Advanced Encryption Standard algorithm, lies at the core of both AES-128 and AES-256 encryption. The AES algorithm is incredibly secure, as well as reasonably fast, making it a perfect fit for VPNs. Looking at both of these variations we can see the biggest between AES-256 and AES-128 is that AES-256 has a longer, 256-bit key. This makes it better against brute force attacks, and this is part of what gives AES-256 the trust of multiple militaries. AES-128 is still quite secure and provides quicker performance.

OpenVPN’s rock-solid security does come at a price, however. The protocol together with OpenSSL stacks up to be a massive 600,000 lines of code. The time it takes for this code to run can pose a problem when trying to maximize speed and performance.


The tech giants Microsoft and Cisco created IKEv2 or Internet Key Exchange version 2 as a joint project in 2005. This is the default encryption protocol found in most iOS and macOS VPNs, and it’s quite comparable to OpenVPN on most fronts. Notably, it uses less CPU power in most scenarios and is better at reconnecting to a device when the connection is interrupted abruptly. It uses similar encryption algorithms to OpenVPN with AES, Blowfish, Camellia, and 3DES being supported.

All in all, IKEv2 is a proven, solid encryption protocol optimized for mobile devices that usually slightly outperforms OpenVPN in terms of speed.


WireGuard, released in 2016 was designed to be a kernel visual interface for Linux devices, rather than a VPN encryption protocol. However, it has since mostly morphed to its modern use- being one of the fastest, leanest encryption protocols out there. Sitting at a measly 4,000 lines of code, WireGuard is incredibly quick. The only issue with WireGuard is that it doesn’t log IP addresses properly for VPN use.

The latest and greatest in VPN encryption

The way WireGuard logs user IP addresses is by storing them all on the same server, without dynamically assigning IPs. Although an issue like this is massive if left unchecked, many VPN companies saw the potential in WireGuard and took to finding a fix.

ExpressVPN, our number 1 VPN choice, uses WireGuard as the core of its Lightway protocol. ExpressVPN takes advantage of a double-NAT system to prevent users’ IP addresses from being stored on ExpressVPN’s servers. ExpressVPN- another top VPN, has Lightway, a similar protocol that revolves around WireGuard.

Although it’ll take some time for WireGuard and its offshoots to prove themselves as secure encryption protocols, there’s no doubt that they’ve got a bright future.

What To Look for When Choosing a VPN

There are a lot of factors that go into picking the perfect VPN for you. You’ll want to take a good look at how you use the internet, and what activities you’ll need a VPN for before you decide. However, there are some universal factors it’s worth paying attention to:

  • Logging Policy: Look for VPNs with a zero-log policy. They won’t retain your data.
  • Server Locations: This is especially important for watching Netflix and gaming- always check out where the VPN’s servers are.
  • Home Country: Ideally, look for a VPN housed in a country that isn’t part of any surveillance alliances
  • Speed: Naturally, you should look for a VPN with top speeds in your area
  • Money-Back Guarantee: A money-back guarantee makes it so you can test out all the VPN’s features extensively before committing
  • Features: Most of the best VPNs come with some peripheral software like dark web scanners, safe search browsers, and more
  • Secure Encryption Protocols: Make sure the VPN supports high-security encryption protocols like WireGuard or OpenVPN

Why Do You Need a VPN?

If you’re not a fan of being tracked and having your every click, tap, or key press monitored, then you need a VPN. If you also often connect to public Wi-Fi, or use torrents and streaming services, having a VPN is almost a necessity.

You might think that a VPN’s only uses are unlocking region-locked content like Netflix, and hiding your data from advertisers like Google. However, that’s only scratching the surface. Let’s see what lies beneath that.

Protect Yourself on Public Wi-Fi | Prevent Snooping on Public Wi-Fi

You’ve probably heard that public Wi-Fi networks are riddled with security pitfalls, and can be dangerous to even connect to. This is because they’re largely not secured, which leads to them becoming hacking hotspots. Cybercriminals use them to steal the private data of anyone who connects to them, then sell it off to the highest bidder. In even more morally dubious cases, they’ll create the network, naming it something like “Free Wi-Fi Station” and wait for people to connect to it.

A VPN can be a lifesaver in these situations. Since VPNs encrypt your traffic, even if the hacker can get ahold of your data (which is unlikely in and of itself) they won’t be able to decrypt it. This lets you connect to public Wi-Fi networks without a care in the world.

Stay Safe Online | Encrypt Your Internet Usage

There’s no shortage of dangers on the internet. Cybercriminals are constantly stepping up their game, discovering new ways to trick people into giving them their data. When most people think of data theft, they think of stolen social media accounts or Netflix logins. However, data theft can be much more notorious, with hackers stealing payment account credentials to take people’s money every day.

Even your ISP can’t see what you’re doing online

Now, while this may not have a high chance of happening to you, a VPN completely eliminates that chance, and lets you rest easy. Even if you accidentally wander to a malicious site, the best VPNs will immediately stop you from entering it, or even sanitize it so that it can’t harm you.

Game With a VPN | Increase Speeds and Change Regions In-Game

If you’ve played online games for any stretch of time, you’ll know that playing games with the game’s servers far away can be an incredibly frustrating experience. Alternatively, in more popular games (LoL, Dota2, and the like), players will migrate to a different server to get more of a challenge.

In both of these cases, a VPN can provide a significant bump in speed and lower your ping. If the game region-locks servers, you can get around that and create an account for whichever region you’d like!

Paid vs Free VPNs

Despite all the benefits a VPN provides, it can be tough to pay for a product you didn’t know you needed. After all, there are free VPNs out there, aren’t there?

Free VPNs do exist, and some, such as ProtonVPN and PrivadoVPN even offer comparable performance to some of the more middling paid VPNs out there. However, with free VPNs, there’s always a catch. Most free VPNs are simply selling your data, however, even the trustworthy ones have restrictions. For example, PrivadoVPN will restrict you to 10GB/month of fast data, while ProtonVPN won’t let you stream Netflix or torrent files through its free version.

Most free VPNs are scams. Remember: if the product is free, then you’re the product!

Even the best free VPNs are way behind the best paid VPNs because of reasons like this. Even the two mentioned above are cases of a company offering a weaker version of their product for free. Sure, if you want to browse the internet for a few hours a month and secure your privacy, a free VPN might be good enough. However, for anything past that, you’ll want to get a paid VPN, as even cheap VPNs give you much more features.

However, there is a way for you to check if a paid VPN would be worth it for you. Take advantage of ExpressVPN’s 30-day money-back guarantee. This lets you use the world’s best VPN for an entire month without risking your cash, getting access to all of its features, without any data throttling or restrictions. Afterward, there are no strings attached, you can subscribe to ExpressVPN, or you can get a refund.

How To Install a VPN?

Installing a VPN can be extremely simple. Let’s look at a few examples using ExpressVPN!

Install a VPN on a PC/Mac


First off, you’ll need to create an ExpressVPN account. You can do this through the button below, by pressing “Sign Up” and providing your desired login details.


Next, you’ll want to follow these steps:

  1. Subscribe to ExpressVPN by clicking the link above.
  2. Download and install the VPN software.
  3. Log in with your credentials from before.
  4. Choose a country to connect to (either on the map or on the menu) and press “Connect”.

That’s all you need to do in order to connect to your server of choice!

Install a VPN on Mobile

Setting up ExpressVPN on a mobile is very similar to doing so on a PC. You’ll once again want to tap the button below and create an ExpressVPN account. Afterward, make sure to pick your ideal subscription level.


From there, it takes just a couple of steps:

  1. Go to the app store on your phone and type “ExpressVPN” in the search bar.
  2. Tap “Install” and wait for it to finish.
  3. Open ExpressVPN and log in using your credentials.
  4. Choose a server on the map, and then “Quick Connect” to connect to it.

And that’s all it takes!

Install a VPN on a Router

Installing a VPN on a router is not only an interesting idea but also one that can allow you to save money while improving your online security. When you install a VPN on the same router, all of your in-house devices connect to, you’ve also protected them from harm without having to pay for a more expensive VPN subscription. This is also an excellent method to get a VPN to function on gaming consoles.

However, before you do this, make sure that your router can process VPN encryption, as most ISP-provided ones can’t. However, if you can get your hands on one that can, following the instructions on ExpressVPN’s router setup guides will have all of your Wi-Fi usage encrypted in no time.

Are VPNs Legal?

As always, this depends on your jurisdiction. Most countries worldwide have no laws outlawing the use of VPNs in order to protect your privacy online. With that being said, certain countries such as North Korea, China, Iraq, Belarus, Russia, Oman, and the United Arabian Emirates do have regulations pertaining to the use of VPNs.

VPNs are legal in most countries

Some streaming networks, such as Netflix, also prohibit the use of VPNs with their service in their terms of service. This is because these streaming platforms make money by streaming region-locked content, and they don’t want you watching it from anywhere in the world.

This is why many people opt to use a VPN to watch US Netflix- as it’s widely regarded as having the best shows. Even if you do use a VPN for this, the worst a streaming service can do is ban you, and they’re highly unlikely to find out if you’re using a good VPN.

With all of that out of the way, it’s important to remember that simply using a VPN doesn’t allow you to do other illegal activities. Whether this be downloading copyrighted content, hacking, or breaking the law in any other way- it’s still illegal even with a VPN.

Conclusion | Use a VPN to Protect Yourself Online

Having covered all of that, it should be plain to see why using a VPN is not dissimilar to keeping your door locked in a rough neighborhood. A VPN keeps all manner of malicious actors, region-locks, and simple inconveniences away from your online experience. Furthermore, it might even increase your gaming performance!

With a first-class VPN, you’ll be able to use the internet untracked, watch US Netflix from abroad, all the while being protected from hackers. You can reap all of these benefits and more with any one of the VPNs we’ve talked about today. However, ExpressVPN stands out as a cut above the rest. It uses military-grade encryption, like its powerful Lightway protocol, to ensure your utmost security online. But if you’re not sure about investing in a VPN just yet, you can use its 30-day money-back guarantee to try it out risk-free!
