Types of VPN
A VPN is useful for increasing your privacy, security, and freedom on the internet, but have you ever wondered how many types of VPN are there? Take a look at the different types of VPN to decide which one best suits your needs.
Different Types of VPN Explained
A VPN builds a private tunnel between your device and the public internet. All your traffic is encrypted as it passes through this tunnel, keeping your personal data safe from ISPs, government surveillance, hackers, and other entities. These tools can be divided into two main types, namely:
Remote Access VPN
Remote Access VPNs are the most popular type of VPN these days. Basically, these connect users to a remote server located in another country. Most commercial VPN services out there are built upon this foundation! They allow you to browse the internet using their own network, encrypting the data you send and receive in the process.
As a result, you can use the Internet with complete privacy, gain access to websites and content otherwise restricted in your region, and safeguard your data from prying eyes on public and private networks. This type of VPN is ideal when it comes to personal use, and might be unsuitable for corporate purposes.
Site-to-site VPNs function differently; they allow companies with offices in multiple fixed locations to create secure connections between each other over the internet. Here’s an example for your better understanding: you’re working out of the San Francisco branch of a large corporation and want to collaborate with employees from the Toronto branch.
Using a site-to-site VPN, sharing information and resources with one another becomes possible. This type of VPN is suitable for large-scale business environments which require private communications between offices around the world. However, they’re impossible to implement without specialized equipment. Site-to-site VPNs can be further divided into two types:
A company that has multiple remote locations can quickly and securely communicate with each other by creating an intranet VPN. This connects each local area network (LAN) to a single wide area network (WAN).
A company that has business ties with other companies can create an extranet VPN to connect each other’s LANs. This enables all parties to work together in a shared network environment while restricting access to their respective intranets.
Client-based VPNs connect users to a remote network via an application/client that handles the establishing and communication process of the VPN. To gain access to the safe connection, the software needs to be launched and authenticated with a VPN username and password. This is how the encrypted link is built between the device and the remote network for secure exchange of data.
As far as implementing a client-based VPN is concerned, operating systems like Mac, Windows, Android, and iOS also come with the option to manually configure the encrypted connection based on a variety of standards. You can choose between SSTP, PPTP, L2TP, and more.

Frequently Asked Questions
Which type of VPN is the best?
Now that you understand the different types of VPN connections available, you might be wondering which one is the best. It all comes down to what your needs are, really. If you’re an individual looking to make use of a VPN for whatever reason, getting your hands on a remote access VPN is a good bet. However, if you own a business and want to ensure secure communications between offices in multiple locations, then a site-to-site VPN is your friend.
How does a virtual private network (VPN) provide additional security over other types of networks?
A VPN provides you with an additional layer of security on any network, but how you ask? It uses multiple protocols like PPTP (Point-to-Point Tunneling Protocol), L2TP (Layer 2 Tunneling Protocol), SSTP (Secure Socket Tunneling Protocol), IKEv2 (Internet Key Exchange version 2), and OpenVPN (Open-Source Virtual Private Network) to create an encrypted connection between your device and the VPN server.
