4 Types of VPNs & How They Function

As we live in 2023, I assume everybody knows about a VPN, what it is, and how it works. However, if you aren’t aware of it, or have never heard about it, don’t worry. I will break it down for you. A VPN allows you to browse the internet privately and securely by re-routing your internet traffic through a remote server. This helps you stay anonymous and prevents you from leaving digital footprints

Can we use any VPN, or are there any specific VPNs? There are 4 popular VPN types that you can pick from. This post explains them based on features, setup, and protocols. Let’s get started.

4 Types of VPNs and How They Function

With the growing concerns about online privacy and security, the use of VPNs has become popular. Yet many users don’t know not all VPNs are the same. Suppose you are also confused about VPNs, and their types, read along.

Common VPN Types

Private/Personal VPN
Remote Access VPN
Site-to-Site VPN
Mobile VPN

Let me give you a brief overview so you can better understand their differences.

1. Private/Personal VPNs

Let’s start with the most commonly used ones first. As the name suggests, a Personal VPN is meant for personal use and is typically used by individuals to protect their online privacy and security.

Here’s how it works:

When you connect to the internet through a Personal VPN, your internet traffic is encrypted and routed through a remote server. This makes it look like you are browsing the web from a different location and hides your IP address. This way, you can protect your online activities from prying eyes, including your internet service provider, governments, hackers, and advertisers.

To use a Personal VPN, you’ll need to subscribe to a VPN service. There are many VPN services available, so it’s essential to research and choose one that’s reputable and offers the features you need. To make things easy, we recommend using Systweak VPN.

Once you’ve subscribed, you’ll need to download and install the VPN software on your device(s). Create an account > choose a server to connect to, and from then on, your internet traffic will be routed through the VPN server.

2. Remote Access VPNs

Now let’s talk about Remote Access VPNs. Often used by employees working from home or remotely, this VPN helps access a private network or the internet remotely.

Here’s how it works:

When you connect to a Remote Access VPN, you create a secure, encrypted tunnel between your device and the VPN server. This allows you to securely access the company’s network as if you were in the office, even if you’re thousands of miles away. To use a Remote Access VPN, you’ll need the following:

A subscription to a VPN service: Select a reputable VPN with needed features through thorough research.
VPN software: Install your chosen VPN software on your device.
Login credentials: Your company should provide you with login credentials that you’ll need to use to connect to the VPN.

Once you have these three things, simply launch the VPN software, enter your login credentials, and choose a server to connect to. From then on, you’ll be able to securely access your company’s network as if you were in the office. Remote Access VPNs are a great option for employees who need to access their company’s network while working from home or traveling. With a Remote Access VPN, you can work securely and efficiently, no matter where you are.

3. Site-to-Site VPNs

Let’s dive into Site-to-Site VPNs. This VPN connects two or more separate networks to create a single, private network. It’s often used by businesses and organizations to connect their different locations or to connect their network to a partner’s network.

Here’s how it works:

With Site-to-Site VPNs, each location has a VPN device, such as a router or firewall, that’s configured to connect to the other VPN devices. Once the VPNs are connected, different networks can communicate as if they were on the same network. This allows employees to access files and resources from any location and collaborate in real-time.

To use a Site-to-Site VPN, you’ll need the following:

VPN devices: Each location needs a VPN device configured to connect to the other VPN devices, such as a router or firewall.
VPN software: Depending on your VPN device, you may need to install VPN software.
Configuration: The VPN devices need to be configured to connect. A network administrator typically does this.

Once the VPNs are set up, they’ll work automatically in the background, allowing the different networks to communicate as if they were on the same network. Site-to-Site VPNs are an excellent option for businesses and organizations with multiple locations or need to connect their network to a partner’s network. With Site-to-Site VPNs, employees can access files and resources from any location and collaborate in real time, increasing efficiency and productivity.

4. Mobile VPNs

Mobile VPN secures your mobile internet connection against public Wi-Fi threats. It creates an encrypted link between your device and the VPN server. They come as standalone apps or as part of mobile device management solutions for secure remote access in organizations. A mobile VPN keeps your connection secure even if you change networks, lose connection, or turn off your device.

Here’s how it works:

Connect to a VPN: To gain access to the VPN, the user must go through authentication, which could be done through passwords, physical tokens, biometric verification, or automatic certification.
A secure connection is formed via the VPN tunnel: The VPN connection in remote access VPN is set up using the mobile’s physical IP, tied to its internet connection. But in mobile VPN, the connection is established through a logical IP, unique to the device and not dependent on the internet connection.
Maintaining VPN Connection on the go: Mobile users may switch between networks, from cellular to Wi-Fi. Despite a change in physical IP, the VPN connection remains intact via the stable logical IP, allowing for a seamless workflow as long as any connection is available.

The Mobile VPN will now protect your device, and you can use public Wi-Fi or access sensitive information with confidence, knowing that your data is secure. Mobile VPNs are essential for anyone using their mobile device to access the internet, especially when using public Wi-Fi.

Different Types of VPNs

So, we have just gone through the four major types of VPNs and how they work. Each type of VPN has unique features and benefits, and the right one depends on your specific needs and requirements. Whether you’re looking to access corporate resources, protect your personal information, or simply bypass restrictions, there’s a VPN that can help you achieve your goals.
