In my constant search for the ultimate VPN solution, I stumbled upon a hidden gem that’s been quietly revolutionizing the VPN landscape—SoftEther VPN.

Imagine a tool that not only provides top-notch security but also offers unparalleled flexibility and performance.

That’s exactly what SoftEther brings to the table. Whether you’re streaming, gaming, or just surfing the web, this multi-protocol VPN software stands out for its simplicity, speed, and robust security.

In this article, I’ll share everything you need to know about SoftEther VPN, why it’s making waves, and how it can transform your online experience. Let’s dive in!

What is SoftEther VPN?

SoftEther VPN (Software Ethernet) is an open-source, multi-protocol VPN software developed at the University of Tsukuba in Japan.

It was created by Daiyuu Nobori as part of his master’s thesis project and has since evolved into a highly flexible and secure VPN solution.

SoftEther supports a wide range of VPN protocols, including its own native protocol, making it a versatile tool for both personal and enterprise use.

Key Features of SoftEther VPN

1. Multi-Protocol Support:

One of the standout features of SoftEther is its support for multiple VPN protocols.

It supports SSL-VPN (SoftEther’s native protocol), OpenVPN, L2TP/IPsec, EtherIP, and SSTP.

This flexibility means you can choose the protocol that best fits your needs or switch between them easily.

2. High Performance:

SoftEther is designed to offer high-speed VPN connections. It uses advanced network acceleration technologies to provide faster speeds compared to traditional VPN protocols.

This makes it a great choice for bandwidth-intensive activities like streaming, gaming, and large file transfers.

3. Strong Security:

Security is a top priority for SoftEther. It uses strong encryption algorithms, including AES-256 and RSA-4096, to protect your data.

Additionally, it supports advanced authentication methods, such as two-factor authentication and certificate-based authentication, ensuring that your connection is secure.

4. Cross-Platform Compatibility:

SoftEther is compatible with a wide range of operating systems, including Windows, macOS, Linux, FreeBSD, Solaris, and Android.

This cross-platform support makes it a versatile choice for securing all your devices.

5. Easy to Set Up:

Despite its advanced features, SoftEther is relatively easy to set up. It comes with a user-friendly GUI and detailed documentation, making it accessible even if you’re not a VPN expert.

How Does SoftEther VPN Work?

SoftEther operates by creating a secure tunnel between your device and the VPN server. Here’s a basic rundown of how it works:

Installation and Setup:

You start by installing the SoftEther VPN software on your device. The setup process is straightforward, thanks to the intuitive GUI and comprehensive documentation provided.

Connection Establishment:

Once installed, you can configure the VPN connection using the protocol of your choice. SoftEther’s native SSL-VPN protocol is particularly easy to set up and provides robust security and performance.


SoftEther supports various authentication methods, including username/password, certificates, and two-factor authentication. This ensures that only authorized users can access the VPN.


Data transmitted through the VPN tunnel is encrypted using strong encryption algorithms like AES-256. This ensures that your data remains confidential and secure from eavesdropping.

Data Transmission:

Once the secure tunnel is established and authenticated, data can be transmitted between your device and the VPN server securely. SoftEther’s high-performance engine ensures that this transmission is fast and reliable.

5. User-Friendly:

Despite its powerful features, SoftEther is designed to be user-friendly. The intuitive GUI and detailed documentation make it accessible to users of all skill levels.

Disadvantages of SoftEther VPN

1. Initial Setup Complexity:

While SoftEther is user-friendly, the initial setup can be a bit complex if you’re configuring advanced features or integrating with existing network infrastructure. However, the comprehensive documentation helps mitigate this.

2. Limited Mobile Support:

Although SoftEther works on Android, there is no official iOS app yet. This can be a drawback if you’re looking to secure iOS devices using SoftEther.

3. Resource Intensive:

SoftEther can be more resource-intensive compared to some other VPN protocols. This is usually not an issue for modern devices but could be a consideration for older hardware.
