SoftEther VPN is an open-source academic project developed by the University of Tsukuba in Japan. It’s a free, popular alternative to OpenVPN that has been in the industry for 15 years since its initial build. So far, it has stood the test of time.

It’s cross-platform, multi-protocol, and completely free of charge. There’s a lot of flexibility that comes with this VPN, as users can also create a client of their own. If you’re looking for a good free alternative to OpenVPN, you should check out SoftEther.

We’ve gone ahead and tested it out to show you how well it holds up compared to other VPN services out in the market.

Note: SoftEther is the parent project of VPN Gate. Although the projects are related, SoftEther VPN is a type of protocol, while VPN Gate is a plug-in module for SoftEther VPN.

SoftEther VPN Pros

Servers and Locations: Choose your own VPN client

Since SoftEther VPN has a child project, VPN Gate, we kept things simple and used it to connect to this protocol.

As mentioned before, you’re free to choose whichever VPN clients or servers you want to import to the software. You’re not just stuck with VPN Gate.

Another great feature is the clone function, which lets you switch back and forth between OpenVPN and SoftEther VPN.

Below is what it looks like when you access SoftEther’s protocol through VPN Gate:

Since you have the ability to choose which VPN client you want to use, the possibilities are endless.

Pricing & Plans: 100% Free

The project is completely free.

*If you want to use their child project, VPN Gate, know that their servers are run solely by volunteers who provide their hardware and bandwidth to support the VPN. They do this in order to keep their services free to the public.

Device Compatibility: Diversity of choices

Known for its diversity and ease of use, SoftEther is a highly compatible protocol. It runs on Windows, Linux, Mac OS X, FreeBSD, and Solaris.

Of course, the number of devices you can use simultaneously may vary according to the client you use. But if you plan to use VPN Gate, you can connect an unlimited number of devices since SoftEther doesn’t require you to sign up.

Sign-Up Process: None, just download

SoftEther does not require you to give out any additional information unless you wish to access their forum to stay in the loop on updates and community activities.

The download links are all displayed on their website. You will have to enter your preferences and device specifications before they provide you with the appropriate download link best suited for whatever device you have.

IP and DNS Leak Test: Clean

SoftEther VPN stays true to their reputation of being a secure and stable protocol. Check out our tests below:

For some clarity: our IP address nor ISP was shown when we ran a leak test using these tools.

Squeaky clean.

Encryption and Protocols: Supports multiple protocols

SoftEther VPN supports the following protocols (as VPN tunneling underlay protocols):

  • SoftEther VPN Protocol (Ethernet over HTTPS)
  • OpenVPN (L3-mode and L2-mode)
  • L2TP/IPsec
  • MS-SSTP (Microsoft Secure Socket Tunneling Protocol)
  • L2TPv3/IPsec
  • EtherIP/IPsec

Again, there’s a lot of flexibility here. With these six supported protocols, you’re well-covered.

SoftEther VPN Neutral Points

Product Interface: Simple and straightforward

Efficiency seems like the main theme of their website. It’s laid out like a Wiki page and is easy to access and navigate for techies who are used to functionality over form.

The same goes for their software. It’s got a simple layout, and it’s easy to keep track of your connections and settings through their client manager.

While there aren’t any eye-catching visuals involved, it’s a straightforward, easy-to-use layout that’s perfect for open-source software.

Customer Support: Public forum

Since SoftEther is open-source software, there’s no official support available.

Instead, you can access a public forum to ask and answer questions from the community. It’s an active community that’s been frequented by users since 2013. There’s one board in English, and another in Japanese.

You may need to register to access their forum. There’s an FAQ for their forum in case you’re confused about how to use it.

The main website also has a knowledge base and simple tutorials to guide you through using the protocol.

Kill Switch: Depends on your client

Since SoftEther VPN is a protocol, you can use a VPN client with a kill switch if it’s a must. Picking a client that has a kill switch won’t be a problem because this is a highly compatible protocol.

SoftEther VPN Cons

VPN Speed and Performance

We weren’t able to connect to these servers for this batch of tests. We’ll update this section when we can get it to work!

Netflix Test: VPN blocked

Boo… Netflix picked up on our VPN use and blocked their content.

Conclusion: SoftEther VPN through VPN Gate can’t access the streaming site, even on the United States server.

Save yourself the trouble and go with the best VPNs for Netflix.

Torrenting Policy: Technically… no

Although SoftEther’s terms do not allow torrenting, there have been reports of users being able to find a way to do so. The volunteer network does not allow P2P traffic.

If you torrent regularly, we recommend these top VPNs for torrenting.

Logging Policy: Security and packet logs

SoftEther logs your connection and disconnection to the VPN server, as well as the type of connection received.

Server logs are collected to identify any unauthorized access and policy breaches. Security logs are always saved in the server log.

You may also save all your activity in packet logs and change your settings. The Logging Service page goes into great detail about how you can customize logs.

SoftEther VPN as a Business

SoftEther VPN’s founder, Daiyuu Nobori, programmed SoftEther1.0 as a personal project in 2003, when he was just 18. At the time, he was a first-year student at the University of Tsukuba. SoftEther1.0 was released in the winter of the same year.

Nobori wanted to use Microsoft Remote Desktop on his campus’ Wi-Fi to connect to his home PC through the internet. This was impossible back then, but it was what inspired him to develop one of the leading protocols in the industry.

SoftEther Corporation Office

In 2014, he opened the project’s source code to the public and released the software with a GPLv2 license.

The project runs under SoftEther Corporation which was founded in 2004. The company had a net income of ~$118,000 in 2017.

As an academic project, SoftEther VPN started offering its services for free when it first started. It still does today.


SoftEther VPN is based in Japan. It is not a part of the 14 Eyes Alliance.

But they do have a history of being close partners with the United States, which is a member of this mass surveillance organization. This means users face a slight risk of their data being exchanged.

SoftEther VPN Conclusion: Good open-source option

SoftEther VPN is a highly versatile protocol. It’s gradually picking up its pace to race OpenVPN to the very top of the open-source foodchain.

Even if it hasn’t been in the industry as much as OpenVPN, the project has been a triumph in its own right. When used appropriately and catered to a user’s needs, the protocol can be just as good as OpenVPN.

If you’re feeling adventurous with your VPN protocol choices or simply don’t want to settle with the mainstream protocol, SoftEtherVPN will do you a solid.

If you’re just learning about VPNs and want to go the more “hands-on” route, this could be a fun way to go about it.

But if you want a quality service without limits on streaming or torrenting, go to our top 10 list of VPN recommendations.

One thought on “SoftEther VPN Project”

  1. Considering the fact that vpn asserts that it is outside of the jurisdiction of the 5 eyes surveillance countries, the SoftEther VPN protocol should also follow suit.

    It is a well known fact that the Japanese Government cooperates with United States and therefore makes it less credible for VPN to claim their exclusion from these countries laws, especially when using the SoftEther protocol.

    Although Japan has many good reasons for maintaining their diplomatic relationship with the United States, it would be welcome site, if projects like SoftEther established and maintained such an exclusion.

    The United States Government (mostly the technically defunct douche-bags that work for the FBI) have been trying to convince US courts and Congress to pass bad laws that are very damaging to privacy and identity protection (contrary to what they want us all to believe).

    EFF, Apple and Google, among many others in the Tech Industry have recently made an appeal to the US Congress over the many threats to privacy, encryption and overall better security that their actions would create, should they succeed in getting the courts to pass these over-reaching laws.

    Needless to say, the fight for Net-Neutrality, Protected Encryption Standards and Digital Freedom and Privacy are far from over. We need the support of other entities around the world whom also genuinely care about user safety and privacy, to draw a line in the sand to protect that which makes us human.

    The tyrants of this world threaten to destroy our privacy rights and take such solace away and in the process, they threaten the very fabric of our human existence.
