VPN technology was developed as a way to allow remote users and branch offices to securely access corporate applications and other resources. To ensure safety, data travels through secure tunnels, and VPN users must use authentication methods -- including passwords, tokens or other unique identification procedures -- to gain access to the VPN server.

For those who are new to using a VPN, one of the most important features will be an easy-to-use interface. You want something as easy as flipping a switch. Private Internet Access offers just that, with an extremely simple Android app. Best of all, a yearly subscription is around $40, which is one of the lowest prices you'll find for a premium VPN.
Oh, heck no. A VPN can help make sure you're not snooped on when connecting between your computer and a website. But the website itself is quite capable of some serious privacy violations. For example, a VPN can't protect you against a website setting a tracking cookie that will tell other websites about you. A VPN can't protect you against a website recording information about products you're interested in. A VPN can't protect you against a website that sells your email address to list brokers. Yada, yada, yada.
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.
