IVPN was one of the fastest providers when we tested US servers using the Internet Health Test. Our budget pick, TorGuard, was faster, but it defaults to the less secure 128-bit encryption. Our non-VPN connection tested at roughly 300 Mbps down. Some tested services are not listed because connection failures prevented some of our tests from completing.
A VPN can be described as an encrypted tunnel that shuttles your internet activity between your PC or phone and a host server. While the internet is a public space, a VPN works by extending an invisibility cloak across the user's activity and allows people to send and receive data in a mostly-anonymous manner. In the simplest terms, a VPN makes it hard for someone to track your activity.
HotSpot Shield is a product that has had some ups and downs in terms of our editorial coverage. Back in 2016, they picked up some very positive coverage based on founder David Gorodyansky comments about protecting user privacy. Then, in 2017, a privacy group accused the company of spying on user traffic, an accusation the company flatly denies. Finally, just this year, ZDNet uncovered a flaw in the company's software that exposed users. Fortunately, that was fixed immediately.
