Virtual private networks (VPNs) have become prevalent, especially with individuals, because they give high-level security without risking availability. They are simple to configure and use and are one of the most important cybersecurity advantages available today. In this End User VPN Security course from Cybrary, students will learn VPNs' history and who is required to utilize a VPN. This course will also teach students about the various types of VPNs and the hardware needed to configure VPNs.

What is VPN?

A virtual private network is a secured and encrypted connection over the Internet from a machine to a network. The encrypted connection makes sure that delicate data is securely transferred. It restricts illegal people from snooping on the traffic and enables the user to carry work remotely. VPN technology is extensively utilized in corporate surroundings. Encryption is a method of putting data in such an order so that only approved people can know the information. It takes regular data and modifies it to look arbitrary to attackers or anyone else who catches it. In this manner, encryption is like a "hidden code."

A VPN operates by building encrypted connections between machines. VPNs usually utilize the IPsec or SSL/TLS encryption protocols. A VPN also stops users from leaving tracks, such as internet history, browsing history, and cookies. The encryption of cookies is particularly critical because it blocks third parties from accessing secret information such as personal data, business information, and other important information on websites.

What End User VPN Security Course is All About?

This beginner-level course from Cybrary is divided into five modules. The first module is the introduction. Surfing the web using an unsecured Wi-Fi network indicates that users could be disclosing their private data and browsing practices. That's why a virtual private network should be mandatory for anyone worried about their online protection and privacy.

In Module 2, students will learn what a VPN is. In this, they will learn that VPN is some digital way to connect between two PCs online. Students will find out how life was before VPN and when VPN was created and why VPN is there and why users and companies easily adopted it. Students will also learn the difference between a VPN and a leased line. Next, they will find out who needs a VPN and the benefits of using a VPN. Finally, they will learn how secure VPN is.

In Module 3, students will learn everything about how VPN works:

  • They will learn how a VPN connection builds a strong connection between users and the internet. How through the VPN, all the data traffic is scattered or routed through an encrypted implicit tube. This hides the IP address when users use the internet, causing the users' location to be unknown to everyone.
  • They will learn about different types of VPNs and some examples of VPN communications. Students will discover how Remote Access VPN, Site-to-Site VPN, and Multi-protocol/Single-protocol VPNs work.
  • They will learn about how to configure the VPN and the infrastructure needed for it.

In this module, learners will find out that VPN servers work as proxies on the internet. Because the location data originates from a server in another location or country, the exact location cannot be determined.

Module 4 and 5 are all about personal VPNs and the security of VPNs. In this, students will learn the pros and cons of VPN usage, market offers, VPNs' safety, and how to set up a personal VPN. Using a VPN is a method to secure data and administer user access to that data. VPNs protect data as users communicate over the Internet.


There are many distinct types of VPNs, and the correct one for users can differ from a primary functionality for informal use. Hackers can apply a variety of techniques to hijack sensitive information users enter on websites. Utilizing that data, they strive to imitate users and access bank accounts and credit card data. With a VPN, users can have high-level protection, such as 256-bit data encryption.

By the end of this course, students should be able to:

  • Understand why we have VPNs.
  • Identify the pros and cons of using a VPN.
  • Understand the basics of VPN functionalities.
  • Understand how to utilize commercially available VPNs.
