ProtonVPN has the unique distinction of placing no data restrictions on free users. You can browse as much as you want, as long as you want. You will be limited to just one device on the service at a time and can only choose between three server locations, but the unlimited data makes up for all that. It doesn't hurt that ProtonVPN, from the same people that brought you super-secure ProtonMail email, is very concerned about security and customer privacy. For all that, ProtonVPN is our Editors' Choice for free VPN.
Trust and transparency issues are the foremost concerns in choosing a great VPN, and if a service doesn’t have enough locations to be useful to you, all the security features won’t make a difference. But after those concerns have been satisfied, we recommend that most people use connections based on the OpenVPN protocol, because of security flaws and disadvantages in the PPTP and L2TP/IPsec protocols. (Experienced users may consider IKEv2, but because it has its own debated pros and cons, we ruled it out.) Though AES 128-bit encryption is fine for most purposes, we prefer services that default to the more-secure 256-bit encryption and still offer good performance.

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.
