TorGuard also lacks extra features that are nice to have, like automatically connecting to the VPN when you’re on an unknown Wi-Fi network (which IVPN offers) or split-tunneling to choose which apps do and don’t route through the VPN (which ExpressVPN supports). And it offers no option to automatically connect to the fastest server, a feature our top pick lacks as well. But if you have above-average knowledge of networking, you’ll appreciate TorGuard’s more in-depth settings pane, which allows you to add scripts or kill specific processes when the VPN disconnects—neither our top pick nor popular services like Private Internet Access allow that kind of control.
Authentication that occurs during the creation of a PPTP-based VPN connection uses the same authentication mechanisms as PPP connections, such as Extensible Authentication Protocol (EAP), Microsoft Challenge-Handshake Authentication Protocol (MS-CHAP), Microsoft Challenge-Handshake Authentication Protocol version 2 (MS-CHAP v2), CHAP, Shiva Password Authentication Protocol (SPAP), and Password Authentication Protocol (PAP). PPTP inherits encryption, compression, or both of PPP payloads from PPP. For PPTP connections, EAP-Transport Layer Security (EAP-TLS), MS-CHAP, or MS-CHAP v2 must be used for the PPP payloads to be encrypted using Microsoft Point-to-Point Encryption (MPPE).
The best VPN services offer a robust balance of functions, server location, connectivity protocols, and price. Some are great for occasional use, others are geared towards surrounding location constraints that companies place on their apps and services, and others are focused on people who download a lot of content and want some privacy while they do.
With  multiple clients, rich with different features, it’s no wonder this VPN service handles more than 10 million users. It covers Microsoft’s and Apple’s operating systems, but also iOS and Android. The interface is not the best out there and could definitely use some work, but these disadvantages are easily overshadowed by the awesome features this VPN offers.

Even TunnelBear's network performance and pricing are just about average compared to other services we've reviewed, except that you can pay anonymously with cash. The company takes security and privacy seriously, explaining its policies and protocols in plain English, and you can read the results of a third-party security audit on the company website.
My rule of thumb is to use a domestic VPN and connect to servers as close to my location as possible. That said, I have had good nights and bad nights getting online. In my recent trip, I found most hotels' networks to become unusable after about 9pm. My theory is that many of the guests were watching Netflix at that time, completely clogging the hotels' pipes.
TunnelBear is the undisputed best free VPN service available today. It's a serious VPN that's serious about customer satisfaction, privacy and security. So the upside is that you're getting a VPN that works, and can be trusted not to hold loads of data on you and sell you out at the earliest opportunity! The downside is that the free tier of TunnelBear only gets you 500MB bandwidth each month. That means for many people having it always-on will leave you caught short well before the end of the month, and absolutely rules out using it to stream endless episodes of Rick and Morty on Netflix. The free VPN tear at TunnelBear is certainly designed as a gateway to the paid tier which offers unlimited data but will cost you real money. If you're going to pay for a VPN we'd suggest getting a premium one like Express, but if you're only interested in a free option then TunnelBear is the one for you unless you need loads of bandwidth.
We recommend against using any so-called free VPN. Free VPN services tend to be significantly slower than their premium counterparts. Their servers are usually congested and the apps often impose bandwidth limits or data caps. Server selection is more limited as well. Besides speed, free VPNs often use shady practices to make money, such as collecting your browsing data to sell to third parties and injecting ads into browsers. Some even carry malware payloads to infect your device.
A remote-access VPN uses public infrastructure like the internet to provide remote users secure access to their network. This is particularly important for organizations and their corporate networks. It's crucial when employees connect to a public hotspot and use the internet for sending work-related emails. A VPN client, on the user's computer or mobile device connects to a VPN gateway on the company's network. This gateway will typically require the device to authenticate its identity. It will then create a network link back to the device that allows it to reach internal network resources such as file servers, printers and intranets, as if it were on the same local network.

Our Findings: During our VPN speed test, we have switched in between different ExpressVPN servers to determine the latency; however, UK was the one we tested several times. We noticed that despite choosing a distant location, ExpressVPN servers manage to deliver fast VPN speed, and the drop was not more than 15%, which is normal. Also, we didn’t experience any connection interruption throughout the test phase. It clearly states that ExpressVPN’s server are smartly optimized to give best streaming experience for Netflix, Hulu, HBO, BBC iPlayer and other media websites.
Windscribe  offers unlimited device connections. Yes you heard that right! The reason is that unlike the others above on this list, it doesn't offer unlimited data. So you're limited by bandwidth and data, not by devices. You get 10GB every month, and there's a free plan also but that only allows one device. There are apps for Windows, Mac and iOS but not Android, and the service also offers browser add-ons with useful features such as ad-blocking. Short range performance (to US sites) is good, but we noticed lag with transatlantic connections. However, if you’re looking to protect the data from a whole bunch of devices - an office, perhaps, or just a smart home - the support for unlimited connections is a real stand-out feature.
Server switching is a feature -- offered by most VPN service providers -- that allows you to change what region or country you're going to connect to. Most providers allow you to switch as often as you'd like (although you usually have to disconnect, then change your configuration, and reconnect). This may be useful if you're trying to hide your location, or if you're running into some communications glitches on the server you're currently using.

In addition to hiding your online activity from a snooping government it’s also useful for hiding your activity from a snooping Internet Service Provider (ISP). If your ISP likes to throttle your connection based on content (tanking your file downloads and/or streaming video speeds in the process) a VPN completely eliminates that problem as all your traffic is traveling to a single point through the encrypted tunnel and your ISP remains ignorant of what kind of traffic it is.

Are you so used to your data traveling over Wi-Fi that you've stopped worrying about the security of that data—and about who else might be spying on it, or even stealing it for nefarious purposes? If so, you are—sadly—in the majority, and you ought to consider using a viritual private network, or VPN. In fact, when PCMag conducted a survey on VPN usage, we found that a dismal 71 percent of the 1,000 respondents had never used a VPN. Even among those who support net neutrality—who you might think would tend to be well informed on technology and privacy issues—only 45 percent had used a VPN.
