What is a VPN?

What are the benefits of using a VPN?

Protect your IP address and your location

Your unique IP address tells the Internet who you are, what you do, and where you are in the world.

Using a VPN, you can change your IP address to any country within seconds so you can get international content and stay private online.

How does a VPN work?

Many layers make up the process of protection that a VPN provides. There are 5 key steps in the workings of a VPN.


  • 01You connect to the VPN. Right away, the server gives you another IP address which hides your real IP.
  • 02All your online activity passes through a secure VPN tunnel that makes it impossible for outside trackers like your ISP to read it.
  • 03Your VPN encrypts your traffic, and forwards it to the intended destination.
  • 04Once the server receives the data you requested, it’s encrypted and sent back to you.
  • 05The right destination decrypts the data you sent out, sending encrypted data back through the VPN.

VPN client

The app you use to access and customize the VPN service.

VPN tunnel

An encrypted environment that your data passes through between your device and the server.

VPN server

A massive data center configured to host and deliver VPN services. Servers can be either physical or virtual.

What are VPN protocols?

VPN protocols are the processes a device uses to connect to a VPN server. Some protocols are ideal for security, others are suitable for speed, or work best in specific situations. There are 9 VPN protocols

OpenVPN

One of the most commonly used VPN protocols, OpenVPN provides a good balance between security and speed.

L2TP

L2TP doesn’t offer any security by itself and is used in conjunction with IPsec for authentication and encryption.

PPTP

The fastest VPN protocol, making it perfect for activities like streaming. However, it’s outdated and not recommended for security.

IKEv2

A more recent VPN protocol that’s fast and compatible with all major mobile operating systems.

IPsec

IPsec is often paired with L2TP and IKEv2, but can be used as a standalone VPN protocol on its own as well.

WireGuard

WireGuard by PureVPN is the latest VPN protocol. It’s open-source, ultra-fast, and uses state-of-the-art cryptography.

What types of VPN can I use?

There are four main types of VPN that you can get for your devices

Free VPN

There are free VPNs. Free VPN options can track you by collecting your data, and have less security options than a paid VPN option.

Personal VPN

You can get a VPN for your personal use. A personal VPN gives you all the tools you need for a private online connection with more freedom.

Business VPN

VPNs in business are used for safety by remote or in-office team members to access the internal company network and the external internet.

DIY VPN

Some tech pros create their own VPN. Making a DIY VPN can exclude security features like shared IP addresses and servers locations in multiple countries.
