Free things usually come with a price. This is particularly applicable to VPNs that limit data usage and speeds to encourage customers to upgrade to paid plans. Some of these companies are known to snatch bandwidth and sell it to anyone who needs it.
A quality VPN should provide reliable encryption, fast performance and many advanced features that aren’t available in the free price. It should be easy to use, and without severe limitations that could hinder your regular internet activities like streaming, downloading, and videoconferencing.
Proton VPN is one of the most popular and well-reviewed free VPN services. Proton VPN offers a free plan that has no restrictions or limitations. It offers decent speeds, three locations and a powerful ad- and malware blocking. P2P and streaming are as well.
Windscribe is a no-cost official source VPN that offers 10GB of data per month, excellent performance, and lots of advanced options. The apps have been developed with a lot of useful tools, tweaks and technology. They also came out on top of my free VPN tests, beating out a variety of fees-based competitors.
