Today privacy is deemed to be a top priority and companies are trying their best to gather as much information or data on users as they can. This collected data is sold to third parties to make advanced targeted ads or worse track you! This is why we have studied, reviewed, and researched the 8 best free open-source VPNs available for Windows 11 that you can download and configure.
We have VPNs on the other side to us all safe and secure but there are a few problems with popular services being infiltrated by security thefts, however, made another privacy issue is with 0-day and government backdoors.
One solution to this is the open-source community, though these are not 100% foolproof but are more secure and carry a good reputation when compared with closed-source choices. Open-source ones are not common when compared with the other services as they are not attracted to the masses and are quite trickier to set them up as well.
Why use an Open Source VPN (Benefits)
The Libra software might seem like a luxury but to be honest, people use it daily. Its code is available publically and the software is a lot trustworthy and reliable.
If the software is not open-source then you need to put in the information it needs, perform the task and then return with the result and you would know that it has done something. With this, you can see each step your information takes to get through to the final result.
As privacy is getting a lot harder to get these are becoming more important among users. It provides users with full transparency and most of the time comes for free and is created by users who are curious about the software and not in the profit.
The biggest upside is that its source code is accessible to the public easily which gives 100% surety that the firm or organization is not hiding anything from the users. It uses different encryption protocols like SSL or TLS which are very secure and have been tested and improvised over two decades.
There come downsides to this as well, these do not carry as many features as closed-source VPNs have as an automatic switch, malware blockers, multi-hop, DNS leak protection and much more.
