A VPN is a private network that uses public infrastructure, such as the internet, to provide remote users secure access to their organization's network. A VPN can be used to allow employees to securely connect to a corporate network from outside the office, for example. VPN encrypts data by using combination of encryption and tunnelling protocols, and create a secure connection between two points, often referred to as a "tunnel." On a VPN connections, your internet traffic is routed through this encrypted tunnel, making it private and secure.

VPN for personal use

  • Remote-access VPNs : Remote-access VPN is used to allow VPN users to remotely connect to a private network for security purposes. For example, an employee who needs access to the company's intranet while they are traveling may use a VPN to access it remotely.
  • Site-to-site VPNs: A site-to-site VPN allows employees to securely connect multiple sites and share files, data, and network resources. This is commonly used by larger organizations that have a number of remote offices or workers who need secure access to the company network.
  • Virtual private LAN service (VPLS): A VPLS VPN is a high-speed network that connects multiple sites using an existing infrastructure, such as the internet. It is commonly used in large organizations that need fast and reliable connectivity between many different branches or facilities.

What are VPN protocols and do they matter?

VPN protocols are the underlying technology that allows VPNs to encrypt and secure your data. There are several different types of protocols, each with their own advantages and disadvantages. Some of the most popular VPN protocols include PPTP, L2TP/IPSec, OpenVPN, and SSTP.

  • PPTP: Point-to-Point Tunneling Protocol is one of the oldest and most common VPN protocols. It is fast and easy to set up, but it is not as secure as some of the other VPN protocols. It is used for both remote-access VPNs and site-to-site VPNs.
  • L2TP/IPSec: Layer 2 Tunneling Protocol is a more secure VPN protocol than PPTP. It uses encryption to protect your data, but it can be slower than PPTP. It is commonly used for remote-access VPNs.
  • OpenVPN: OpenVPN is a VPN protocol that is known for being both secure and fast. It uses SSL/TLS for encryption, which makes it more secure than PPTP and L2TP/IPSec. It is also one of the most commonly used VPN protocols.
  • SSTP: Secure Socket Tunneling Protocol is a VPN protocol that is primarily used on Windows. It uses SSL/TLS for encryption, which makes it more secure than PPTP and L2TP/IPSec. However, it can be slower than OpenVPN.

When you are choosing a VPN provider, it's important to consider the VPN protocols that they offer. Some providers only offer one VPN protocol, while others offer multiple. Choose a provider that offers the protocol that you need. Ultimately, the type of VPN protocol that is best depends on your specific needs and preferences.
