The History of VPN Development and Why VPNs Emerged

The History

The development of VPNs has gone through multiple stages, namely personal VPNs and corporate VPNs. The main difference between these two stages lies in the user groups and purposes of use. During the personal VPN stage, users primarily aimed to access information and resources from abroad, whereas the corporate VPN stage was mainly for protecting corporate data and resources to increase work efficiency.

Why VPNs Emerged

In the age of the internet, people require fast and secure access to online information and resources. However, in some countries and regions, due to policy and legal restrictions, users cannot normally access the international internet. To address this issue, VPN technology was developed. The primary function of a VPN is to create a secure and encrypted tunnel between the user and the internet, enabling users to access the international internet from any location, at any time, without being detected by local internet regulatory bodies.

The emergence of VPNs has provided users with a convenient and secure way to access the internet, helping them overcome geographic restrictions and gain access to more information and resources. At the same time, VPNs have played an important role in corporate network security. They enable features such as data confidentiality, authentication, bandwidth control, security monitoring, and management, which enhances the work efficiency and security of enterprises.

Differences between personal VPNs and corporate VPNs

Different application scenarios: Personal VPNs are typically used for bypassing internet censorship and accessing overseas websites, helping individual users circumvent network restrictions. On the other hand, corporate VPNs are used to connect internal corporate networks with external networks, allowing employees to securely remotely access internal company network resources. This includes functions such as data confidentiality, authentication, bandwidth control, security monitoring, and management.

Different costs and licensing: Personal VPNs require a certain fee, usually paid on a one-time basis or based on traffic usage. Corporate VPNs require the purchase of licenses and equipment and need to be managed and monitored internally within the enterprise.

Different levels of network security: Personal VPNs generally have lower network security and are more vulnerable to hacking attacks and data breaches. Corporate VPNs have higher requirements for network security, using secure protocols and components such as L2TP VPN to protect corporate data security.

Different authorization and number of users: Personal VPNs are usually only intended for individual use, while corporate VPNs can support multiple users at the same time.


The main differences between personal VPNs and corporate VPNs are in terms of application scenarios, costs and licensing, network security levels, and the number of users. When choosing a VPN service, users should select the appropriate service provider and plan based on their needs and budget.
