Hotspot Shield VPN
Perhaps the best known free VPN service based in the USA but their free offering is feature limited and ad supported.
Pros & Cons:
Hotspot Shield is perhaps the best known free VPN service. Based in the USA their free offering is feature limited compared to their commercial service. It is also ad supported. The free version only has access to servers in the United States and has a data limit of 750MB every 24 hours for desktop clients and 256MB for mobile.
Hotspot Shield Free does not allow access to NetFlix, Hulu and some other streaming video sites. Additionally the free VPN network runs so slow that it's likely you will see a lot of stuttering watching streamed video.
The advertising feature of Hotspot Shield has been criticized because the program changes your browser settings in order to inject ads into your web browsing. Some have even labeled the product as spyware but in reality it is simply adware.
Hotspot Shield VPN was reviewed by Gizmos Freeware on based on version 4.15.3.
