With so many VPNs on the market these days, it might be hard to believe that there was once a time when they were primarily used by workers who needed to remotely connect to their corporate networks.

Now, the best VPNs are a lot more versatile, and do everything from shoring up your digital security to unblocking content from around the world. However, if you're new to the world of VPNs, you might be wondering how you and your VPN would do any of this.

The good news is that you don't have to be a cybersecurity expert to make good use of a VPN. In this guide, I'll walk you through setting up your VPN, choosing a server, and discussing why VPNs are so darn handy.

What is a VPN?

VPNs are privacy tools that route your internet traffic through a secure tunnel. The traffic is encrypted in the tunnel – which means good things for your digital privacy. Anyone who tries to take a peek at what you're doing online will be disappointed. As a result, you'll be able to go about your day-to-day browsing without your internet service provider, government, or hackers watching over your shoulder.

When you connect to a VPN server, you'll also be given a brand new IP address based in the same place as the server. So, join a UK-based server, and you'll have a UK IP address. Any sites you visit will see this IP address and think you're in the UK, too, and let you access region-specific content that might've been locked behind geo-restrictions otherwise.

How to use a VPN

Whether you're looking for the cheapest VPN on the block or the best VPN for streaming, today's top providers are all incredibly easy to use. Below, I've broken the process down into bite-sized chunks:

1. Pick a VPN provider

Today, we're spoiled for choice when it comes to VPNs, but it's important to remember that some services are more reliable than others – stick to a reputable pick to avoid disappointment.

2. Download and install the VPN

Visit the VPN's website once you’ve made up your mind, and download the app that's compatible with the device you're using. You'll also need to decide how long to subscribe for and sign up for an account.

Cover your bases

VPNs are massively versatile, and you'll be able to use your service on your desktop, mobile, games console, smart TV, and even your router. 

3. Log in to your VPN

Here, you'll be asked to input the information (like your username and password) you provided earlier. 

4. Connect to a VPN server

Take a look through your VPN's server list to find the server that suits you. If you're looking for speed and security, just hit the 'quick connect' button to be automatically paired up with a nearby server. Then, you're all set – you'll be connected to your VPN and protected from invasive snoopers.

How to choose the right VPN server

Convenience is king, even in the world of VPNs, which is why you'll find most services have a 'quick connect' feature. Hit this button, and you'll get matched up with a server automatically. That's handy if you're in a rush, or if you're not choosy, but not if you want to be in the driver’s seat.

There might be times when you want to connect to a server in a specific location to access its region-locked streaming content – or you might want to join a server close to your real location to maximize your speeds. Luckily, it's pretty easy to pick and choose.

Typically, you'll find most VPNs organize their servers into lists, which you can scroll through to your heart's content. It's handy if the provider includes a search box, too, as well as dedicated servers for specific tasks (think unblocking streaming platforms, gaming, torrenting, and more). NordVPN takes things to another level with its interactive map that lets you literally pinpoint your target location (and its severs).

Why use a VPN?

Getting a VPN up and running is all well and good, but why bother? Are there any major reasons (other than their privacy-boosting benefits) to invest in one? These are good questions – and I'll walk you through some answers.

Supercharge your security

Protecting your digital privacy – that's a VPN’s bread and butter. They establish a secure tunnel between your device and their servers, and the data that travels through this tunnel is wrapped in encryption and kept safe from prying eyes.

These can include your ISP, network admins, your government, and the garden variety cybercriminal. With a VPN, you can browse the net without worrying about whether someone is keeping track of what sites you land on, what apps you use, or which files you're downloading.

Better public privacy

Okay, so, when you're in a cafe (or a hotel or airport, for that matter) and you connect to the free public Wi-Fi, you're probably thinking "this is pretty handy". It is, but it's also risky. These hotspots are usually unencrypted, meaning your personal details aren't protected from nosy cybercriminals monitoring the network. If you input any login details or buy something whilst connected to the hotspot, you might be sharing your sensitive information with a snooper.

Connect to a VPN whilst you're out and about, however, and you're good to go – thanks to the VPN's secure, encrypted tunnel that renders your info unreadable to nosy digi-neighbors.

Unblock content

Have you ever lamented the fact that the US Netflix library seems so much better than everyone else's? Me too – but that's exactly why so many people are checking out VPNs, these days.

When you connect to a server in a different country, you'll be given a new IP address based in that same place, too. Sites like Netflix will think you're physically there – and, as a result, show you that country's content library. This is called 'geo-spoofing', and it's a pretty neat way to bypass annoying geo-restrictions that’d otherwise keep you from checking out news shows and old favorites.

Stay speedy

Have you ever been on the fourth season of a TV boxset marathon, or in the middle of some torrenting, and then suddenly your videos are grainy and your downloads slow to a crawl? If so, you might've been impacted by ISP throttling. ISPs do this on purpose, slowing your connection to conserve bandwidth if it decides you're using too much. It's annoying – but VPNs can put a stop to it.

Basically, by encrypting your data, VPNs prevent ISP from monitoring your browsing sessions, figuring out what you're doing (whether that's HD streaming, gaming, or torrenting), and pushing the big red throttle button.

Torrent safely

Elephant in the room time – yes, some people use protocols like BitTorrent to download copyright files, which has contributed to the idea that peer-to-peer sharing is inherently bad. However, P2P is totally legitimate so long as you're playing by the rules.

ISPs sometimes take a different view, however, and throttle or block P2P traffic. VPN encryption is a remedy for this – seeing as it stops your ISP from filtering out P2P traffic, prevents anyone from reading the contents of the files you download, and means that anyone connected to your network will see the VPN's IP address rather than yours.

Keep the gaming going

The benefits of masking your real IP don’t stop there, either. When you're gaming, some (entirely swagless) players might try to gain an advantage by targeting you with a DDoS attack – where they overwhelm your home network with traffic.

They'll have no luck if you’re using a VPN, though, because they'll be targeting the VPN servers, not your home connection – and you can pick another server, connect to it, and keep on playing.

FAQs

Why should I use a VPN?

VPNs keep you safe online by encrypting your traffic. As a result, your traffic and personal details will be unreadable to third parties – including your ISP, hackers, and websites. We all share a lot of information over the web (whenever we buy something online, check our bank, or log in to social media sites), after all, so it needs to be well-protected. 

When should I use a VPN?

Well, that depends – what are you using your VPN for? If you're trying to unblock content from around the world, for example, you'll need to switch the VPN on when the popcorn is ready and it's time to watch. Want to stay safe on public Wi-Fi? Turn on your VPN before you connect to the cafe's network. Alternatively, if you have more of a blanket concern about your digital security, it’s probably a good idea to have your VPN on most of the time. 

Can I use a free VPN?

You can, but it's not always a good idea. Some free VPNs are reliable samples of their paid cousins – but most come with restrictions and limitations. You might have fewer server locations to choose from or a stingy monthly data cap, for example. The worst kind of free providers are totally bogus, and only interested in collecting your data to sell on for a profit. I'd recommend sticking to a fully-fledged service – but you can get a feel for some of the industry's top VPNs with a VPN free trial
