Understanding the Different Types of VPNs
By Laura Baker, Executive Director of CyberWyoming, with the help of Claude AI.
VPNs are like secret tunnels that allow you to access the internet privately and securely. There are several kinds of VPNs, and they work in different ways. Let’s explore the main types.
1. VPN on a Firewall Appliance
This type of VPN is often used by businesses and organizations. It involves a special piece of hardware called a “firewall appliance” or “firewall” that creates a secure connection between different networks. Imagine it as a gateway that allows authorized computers and devices to communicate with each other safely, like a secret clubhouse.
Businesses often use this when employees work from home and need to access the systems resident at the office. Some companies require any employee working remotely to VPN into the home office network and then access the internet through the home network security protocols.
When setting up this type of VPN for a small business, you will probably need some IT help.
2. VPN Service
A VPN service is something you can subscribe to as an individual or a family. Companies like NordVPN, ExpressVPN, and TunnelBear offer these services. When you use a VPN service, you connect to their servers through an encrypted tunnel, making your internet traffic private and hiding your location. It’s like using a disguise to visit different websites without anyone knowing it’s really you.
To use this type of service, you just download the software from the company you choose, create your account, connect to the internet, and then choose the VPN button (ex. NordVPN icon) to activate your secure tunnel. Usually, these services allow you to protect up to a certain number of devices. They are great for traveling and easy to set up! I’ve heard of sports fans using them to watch the Olympics from Britain because they like the coverage better.
3. VPN Built into a Browser
Some web browsers, such as Epic Privacy Browser and Opera Browser, come with a built-in VPN feature. This means you don’t need to install any additional software or subscribe to a separate VPN service. When you enable the built-in VPN, your browser traffic is automatically encrypted and routed through a secure tunnel, protecting your online activity within that specific browser.
While these VPNs aren’t rated as highly as the firewall VPN or the VPN service, they could be used in a pinch, but remember that it only encrypts the traffic on the browser, so if you use Outlook for your email that is not encrypted.
Summary
All these types of VPNs have one thing in common: they help keep your internet activity private and secure. The main difference is in how they are set up and used. Businesses often use VPNs on firewall appliances, while individuals and families might prefer a VPN service or a browser with a built-in VPN for their personal use.
Remember, using a VPN is like having a secret code that keeps your online activities safe from prying eyes. Just be sure to choose a reliable and trustworthy VPN option that suits your needs.
