With the internet awash with genius-level hackers, sneaky phishing attempts, and just shady dealings altogether, VPNs are becoming more and more important. But why? What is a VPN and what exactly does it do?

In short, a VPN is one of the best and most secure ways to access the internet while protecting your data at the same time. They create an encrypted “tunnel”  between your data, the VPN’s server, and the internet. Any data that exits the “tunnel” is masked as the VPN instead of showing up as your own.

What is a VPN and what does it do?

A VPN (Virtual Private Network) works as a secured connection between your data and the internet. Think of it like a private tunnel that hides your personal information from unwanted viewers or even tricks them into thinking you’re somewhere that you’re not. When your data exits the VPN’s encrypted tunnel and hits the internet, it’s coming out disguised as the VPN itself. In turn, this makes it a lot harder for hackers to hijack your personal information.

Providing security and anonymity are the main purposes of a VPN. Similar to how a firewall will protect data that’s stored on your PC by providing a layer of defense against intrusion, a VPN protects your data that’s passing through the internet. But, that’s not their only purpose.

You might be thinking, “but Branton, that sounds just like a proxy?!” and you wouldn’t be wrong. However, unlike a proxy connection, a VPN secures more than just your browser. It works to secure your entire internet connection by essentially replacing your ISP routing for absolutely everything. So, yeah, a VPN is definitely like a proxy, but proxies don’t usually offer the same level of protection – or anonymity – as a VPN does.

VPNs also work to mask your location. Meaning, you can use a VPN to subvert various region locks on content and websites.

You can even install a VPN at the router-level to secure your entire home network. If you have a lot of smart devices, or an entire smart home, this is often one of the best options to build an extra layer of security. Once your router is secured by a VPN, every WiFi-enabled device that connects to it will pass data through your encrypted tunnel before it hits the internet.

Should you be using a VPN?

Short answer: Yes.

VPNs are especially important if you do online banking or anything else along those lines. If you conduct any business online, say you’re a freelancer or a remote contractor, a VPN should be enabled pretty much 100% of the time.

What if you’re connecting to a public network? Maybe at a coffee shop, an airport, or a hotel? It’s an easy answer, always use a VPN when connecting to a public network, regardless of where.

The opposite would be like shouting your personal information in the middle of a busy mall. Sure, most people will ignore it, but not everyone will. Some people will gladly take that information and use it against you, whether that’s signing you up for fraudulent credit cards, or something even worse like full-blown identity theft. Scary, right?

Similarly, if a hacker/phisher gets access to something like your online banking information, a lot of really bad damage can be done faster than you could say “I should have been using a VPN”.

Long story short, if you want to keep your important personal information safe while browsing online, you should be using a VPN.

VPN Providers

There are tons of VPN providers you could choose from, some are free but the best options are paid.

Out of all the options, my favorite VPN to recommend is NordVPN for the simple reason that it works with everything. Whether you’re running Windows, Linux, or even MacOS, NordVPN will work, and work well. They even have apps for all iOS and Android devices. It’s super easy to set up and really quick to turn on and off.

Plus, with plans starting at just $2.99/mo, NordVPN is also one of the most affordable VPN providers.

But, they’re not your only good option. TunnelBear, Express VPN, and Norton VPN are all great alternatives.


Whether you’re browsing the web or paying bills, a VPN is practically necessary in today’s always-online world. Now that you know what a VPN is and what they do, you should have no reason not to be using one.

With more people online than ever before, we also have more hackers and phishers than ever before. To make sure they’re not stealing your personal data, you should be taking steps to protect yourself, running a good VPN is undeniably one of the most important (and effective) steps you could take.

At first, I didn’t think that I needed a VPN (since I didn’t understand what it is and what it does), but after talking to a friend of mine, I was convinced that I needed one to increase my security online. I decided to go with my friend’s recommendation (Surfshark), and I was pretty happy with my choice since it had an easy to use app. Also, what I learned after that there are plenty of benefits as well, such as bypassing geo-blocks and getting better price deals for traveling!


It’s not even a discussion… should You be using VPN? SURE. Ask yourself if you care about your privacy and security online? I doubt that someone would answer no to this one. By the way, Branton, loved the article and you VPN recommendations, couldn’t agree more on NordVPN – it performs very well for me yay.


I like to use express vpn. Does anyone know if it’s good?


Chase it is definitely a good option. A bit more expensive, but you get what you pay for. Good for streaming Netflix as well.
