Websites using Google Analytics and various advertising networks can very well track and identify visitors based on a variety of different inputs with their browser (see browser fingerprinting). Therefore it’s best to use a VPN in conjunction with a secure browser configured for more privacy. See my guides: secure browser (an overview of different browsers) and also Firefox privacy, which deals with privacy configurations, tweaks, and add-ons.
We spent more than 130 hours researching 32 VPN services, testing 12, interviewing the leadership of five, and consulting information security and legal experts. We found that a VPN shouldn’t be your first step toward online security, but for protecting your info on public Wi-Fi (and in some other cases), IVPN is the most trustworthy provider that offers fast, secure connections and easy setup.
These services offer many ways to connect, including without the service's client software; support operating systems and devices, such as routers or set-top boxes, beyond just the "big four" operating systems (Windows, Mac, Android and iOS); have hundreds, or even thousands, of servers in dozens of countries; and generally let the user sign up and pay anonymously.
VPNs can make your browsing private, but that doesn’t necessarily mean you’re anonymous. VPN services can and do log traffic (even the ones that say they don’t log do need to log some information, or they wouldn’t be able to function properly), and those logs can be requested by the authorities. Think of a VPN as being like curtains: people can’t peek through your curtains if you’ve got them closed, but curtains won’t hide your house.
We contacted each of our finalists with simple questions about its service and troubleshooting. Most VPN companies provide technical support through online ticketing systems, meaning you’ll need to wait for a response. This means that self-help support sites are even more important, since waiting for a reply while your connection is down can be frustrating. Response times to our support inquiries ranged from 20 minutes to a day.
Similarly, many VPN companies would rather not have to deal with the legal implications of their services being used to download via BitTorrent. BitTorrent is, of course, not inherently illegal but it is often used to pirate copyrighted material. Very few VPN companies outright ban BitTorrenting on their servers, while others restrict its use to specific servers.
You get your standard secure VPN account, encrypted Wi-Fi, P2P, IPv6 leak protection, a VPN kill switch, and a whole lot more. Private Internet Access VPN sure as hell isn't a sexy app you want to open all the time (so just set it to automatically open when you log in), but what it lacks in aesthetics it makes up for with a long list of features. It also has a solid backbone, claiming over 3,100 servers in 28 countries worldwide.
Users utilize mobile virtual private networks in settings where an endpoint of the VPN is not fixed to a single IP address, but instead roams across various networks such as data networks from cellular carriers or between multiple Wi-Fi access points. Mobile VPNs have been widely used in public safety, where they give law-enforcement officers access to mission-critical applications, such as computer-assisted dispatch and criminal databases, while they travel between different subnets of a mobile network. Field service management and by healthcare organizations,[need quotation to verify] among other industries, also make use of them.
HTTPS is a powerful tool that everyone should use because it helps keep sensitive browsing private at no extra cost to the people using it. But like most security standards, it has its own problems too. That little lock icon in your browser bar, which indicates the HTTPS connection, relies on a certificate “signed” by a recognized authority. But there are hundreds of such authorities, and as the EFF says, “the security of HTTPS is only as strong as the practices of the least trustworthy/competent CA [certificate authorities].” Plus, there have been plenty of news stories covering minor and even major vulnerabilities in the system. Some security professionals have worried about those least-competent authorities, spurring groups to improve on the certificate standards and prompting browsers to add warnings when you come across certificates and sites that don’t withstand scrutiny. So HTTPS is good—but like anything, it isn’t perfect.
The first runs in the VPN client app on your computer, so if the VPN connection fails while the VPN client app is running, that VPN client app can turn off the computer or mobile device's internet connection. However, if your VPN connection has failed because the VPN client app itself crashed, then the kill switch may not work, and your IP and data may leak onto the internet.

If the data isn't encrypted — and that depends on the website you're connecting to — then the traffic might be intercepted and read. (One well-known VPN provider was recently accused of inserting ads in users' web browsers, which would violate users' security and privacy.)
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.
As part of our research, we also make sure to find out where the company is based and under what legal framework it operates. Some countries don't have data-retention laws, making it easier to keep a promise of "We don't keep any logs." It's also useful to know under what circumstances a VPN company will hand over information to law enforcement and what information it would have to provide if that should happen.
When we test VPNs, we generally start with the Windows client. This is often the most complete review, covering several different platforms as well as the service's features and pricing in depth. That's purely out of necessity, since most of our readers use Windows (although this writer is currently using a MacBook Air). We currently use a Lenovo ThinkPad T460s laptop running the latest version of Windows 10. We periodically upgrade to a newer machine, in order to simulate what most users experience.
