Let’s break down everything you need to know about what is VPN?
What is VPN?
A VPN, or ‘Virtual Private Network’, allows you to maintain and establish a protected network connection while using public networks, Wi-Fi hotspots, and your home broadband in real-time. The VPN disguises your online identity, like your IP (internet protocol) address, which in turn masks your online activity and location. It can also enable you to gain access to internet content that was previously unavailable to you.
We know that is a lot of technical jargon, so let us break it down for you further. Your IP address is the unique string of numbers that identifies each computer using the Internet Protocol to communicate over a network. Hiding your IP address makes it much more difficult for third parties to track your online activities and steal your data.
When a VPN disguises your location, the VPN server is acting as proxy. However, we know that one of the most common VPN purposes is to help log into streaming services like Netflix or Paramount Plus, to watch TV shows or movies that your region doesn’t typically have access too. It’s okay, we know watching Peep Show on UK Netflix is too appealing to deny.

Do I need a VPN?
Getting hold of a VPN can be useful for just about anyone who uses the internet, but some situations that require it are far more pressing. For example:
- While using public Wi-Fi – sure, it’s great to save some mobile data by hooking up your phone to the coffee shop Wi-Fi, but public hotspots are particularly vulnerable to hacker attacks. If you use a VPN while connected to public Wi-Fi, your online traffic is invisible, so you can browse in full privacy without putting your data at risk
- While traveling – if you want to access your home content while jet-setting off on holiday or popping on a plane for a business trip, you can simply use your VPN to change your location
- While browsing the internet – marketers, service providers, government agencies, and others all jump at the opportunity to track and collect your private data and browsing history. Put a stop to it by hiding your activity through a VPN
- While shopping – a VPN ensures that you keep your credit card details safe, while also allowing you to avoid fake websites, targeted pricing, and other annoying schemes
- While streaming – watch your favorite TV shows anytime, any place, without worrying about region locks or your IPS throttling your connection
- While gaming – VPNs can help you avoid DDoS attacks and bandwidth throttling during gaming sessions
How does a VPN work?
Here’s how a VPN works behind the scenes:
- When you connect to a VPN, it authenticates your device with a VPN server
- The server applies an encryption protocol to all the data you send and receive
- The VPN secures the data as it travels between you and your destination
- To ensure your data always stays secure, the VPN forms an outer packet around it, known as an encrypted encapsulation
- When the data arrives at the server, the server removes the outer packer through a decryption process

What does a good VPN do?
A good VPN will utilize the benefits we’ve listed above, but it will also provide best-in-class features such as the following:
- IP address protection – Hiding your IP address is the number one task of a VPN, and allows us access to those sweet Netflix movies in other regions. It allows you to send and receive information, while keeping your IP address hidden.
- Kill switch feature – Sometimes your VPN connection may be interrupted, and that means your secure connection is at risk. With a good VPN, it will notify you of this downtime, while eliminating programs on your computer to reduce data leaks. You’ll need to preselect this programs beforehand, though.
- Protocol encryption – Your search history and cookies can be targeted if you’re not careful, but a good VPN will encrypt them to prevent third parties from potentially gaining access to confidential information.
- Two-factor authentication – Using this feature will ensure that your VPN is protected with another layer of security. You might be prompted to enter a keyword phrase, code, or password to gain access. These are often sent to your device as you attempt to log in.
Are VPNs free?
Some VPN applications and extensions can be downloaded for free, but most VPNs require a paid subscription or license to fully access their features.
