What is a VPN?

You may think your online activity is safe from prying eyes – but do you really know who is collecting your data and watching your every digital move?

A Virtual Private Network (VPN) offers an encrypted and secure connection between your device and the internet. Like a hidden “tunnel,” a VPN lets you move around the web freely – whether you’re browsing at a local coffee shop or accessing geo-restricted media.

Why Use A VPN?


Virtual private networks allow you to “tunnel” behind online systems that automatically track your device’s IP address – reducing the risk of hackers finding personal information to use in password cracking.


A VPN gives you freedom to access the web without geo-restrictions and censorship. Perfect for trying to access content or sites that may have location restrictions or content blocks.


Even a strong password can’t guarantee your data stays safe online. A VPN puts a stop to malicious activity aimed at your device and internet connection with encrypted tunnel technology.

When Do You Need A VPN?

Whether you're traveling abroad or just trying to browse without fear, VPNs can give you an extra sense of security online.

While using public Wi-Fi

Trying to get work done in public places? “Free Wi-Fi” isn’t always free – with internet providers and hackers gobbling up your data on open connections. Using a VPN allows you to take advantage of public access without fear.

When traveling

Have you ever been traveling and found that a site you always used is now blocked — or specific content on Netflix or Hulu is region-locked? Load up your VPN and get around location locks online no matter where you are. A VPN can mimic the IP address of any location, letting you browse freely.

While browsing online

Just because you are “incognito” doesn’t mean you’re hidden. A VPN gives you encrypted access to the web – and certainty that your digital search and browsing history aren’t being tracked.

When shopping

You may be surprised to learn that your device’s location can play a big role in how much you’re charged online for goods and services. Why pay more? Your VPN can help you take advantage of local rates and discounts.

How Does A VPN Work?

When you want to move through the web without being tracked, your VPN creates a secure connection between your device and the internet.


Your data is securely routed to the VPN tunnel

With a VPN, you connect to the web via a secure tunnel. This means all data sent and received is encrypted, making it virtually impossible for anyone to intercept or decipher your online activity.


Your data moves to secure servers via the tunnel

While big internet companies track your online behavior and collect data for targeted advertising, a VPN protects your privacy by routing your data through secure servers.


Your VPN server decrypts the data and sends it to the site you are visiting

In the blink of an eye, your VPN’s server connects you to the website you are trying to access. This server acts as an intermediary, decrypting your data and sending it on its way to the site.


Your browsing activity remains private

Since all of your data is encrypted while using a VPN, your internet service provider (ISP) or any other third parties cannot see what websites you are visiting or what information you are exchanging with them. This ensures that your browsing activity remains completely private.

The Science Behind VPNs

What is an IP address?

Your device has a unique identification number called an IP address. This is used to identify and communicate with your device on the internet. Every time you connect to the internet, your device is assigned a new IP address.

How does a VPN change my IP address?

Rather than use your own IP address to access the internet, a VPN creates a unique tunnel for your internet traffic. This means your IP address is changed to match the location of the VPN server you want to connect to. connected to. So, if you connect to a server in Japan, it will appear as though your device is located in Japan!

What does “encryption” and “encryption key” mean?

It sounds fancy, but encryption is simply a way to protect your data and keep it private. It works by converting your information into a secret code that can only be read with the correct “key”. This key is like a password, and it allows you to access and decrypt your data.

What about “kills switches” and “split tunnels”?

Many providers offer features like kill switches and split tunnels to help keep your VPN secure and completely private. A kill switch is a safety measure that will shut down your internet connection if the VPN unexpectedly disconnects. This prevents any of your data from being exposed to outside sources. Split tunnels let you choose which traffic goes through the VPN and which goes through your regular internet connection.

VPN Protocols

VPNs work on specific rules and processes that determine how your data is moved through the internet. These rules and processes are called protocols – with each built to focus on particular use-cases for VPNs depending on your need. Click the tabs to read more about each VPN protocol.

How to choose a reliable VPN service?

What To Look For In A Reliable VPN Service

Don’t limit yourself to a single VPN protocol when choosing a VPN service. When a VPN provider offer multiple protocols, you can trust that you’re getting the best overall experience every single time you log in. Always check a VPN service offers multiple protocols in their system.

High Speed & Performance

The last thing you want is a slow and unreliable VPN service. Look for a provider that offers high-speed servers in various locations to ensure fast connection speeds, especially if you plan on streaming or downloading large files.

Multi-Platform Functionality

You use multiple devices every day – so make sure your VPN provider can keep up. Look for VPN services that offer the same powerful protocols and uptime for all possible devices – so you never risk being without a secure connection.

Never Trust A “Free VPN”

Here’s a trusty saying: “A free VPN is a bad VPN.” VPN services also need to make money to provide access – so those who don’t charge may look to sell your data to make ends meet. Don’t be afraid to invest in higher-quality security.
