In very simple terms, a VPN connects your PC, smartphone, or tablet to another computer (called a server) somewhere on the internet, and allows you to browse the internet using that computer’s internet connection. So if that server is in a different country, it will appear as if you are coming from that country, and you can potentially access things that you couldn’t normally.
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.
It’s also a great way to enjoy unlimited streaming and outstanding security without committing to an expensive plan. After all, if you want to understand why people love VPNs without paying, you shouldn’t use a slow, spammy, free program. Instead, try a great service like ExpressVPN or NordVPN for free. If you love it as much as these real users did, keep it – and if not, cancelling your trial is easy.
The main reason to use a VPN is security - in theory, the data that travels across your VPN should be impossible for anybody else to intercept, so it can protect your online banking or confidential business communications - but there are other benefits too. VPNs can make it much harder for advertising to track you online, and they can overcome geography-specific blocks that prevent you from accessing some country-specific services such as online video.
There’s no point to a VPN that interferes with or logs your traffic—your ISP already does that. Free VPNs, such as Facebook’s Onavo, explicitly gather traffic data to resell or use it for marketing. We looked carefully at the privacy policies and marketing claims for each company we considered. In some cases, companies we considered had sworn in court filings that requests for data were impossible to fulfill. In other cases, we asked companies about their internal security and privacy standards to gauge the trustworthiness of their statements on logging.
Identity theft occurs when thieves steal your personal information and use it to commit crimes in your name — like taking over or opening new accounts, filing tax returns in your name, or renting or buying property. A VPN can help protect against identity theft by helping protect your data. It creates an encrypted tunnel for the data you send and receive that’s out of reach of cyberthieves.
If you don't know what Kodi is, you're not alone. However, an analysis of searches leading to our site reveals that a surprising number of you are, in fact looking for VPN that works with the mysterious Kodi. Dictionary.com defines Kodi as a possible misspelling of "Jodi," but PCMag analyst Ben Moore clarified for me that Kodi is "free, open-source software for managing your local collection of movies, television shows, music, and photos."
CyberGhost gives Mullvad some stiff competition in the speed department, especially for locations in North America and Europe. It does a good job protecting user anonymity, too—requiring no identifying information and using a third-party service for payment processing—albeit not to the same degree as Mullvad. Add to that CyberGhost’s unique, easy-to-use interface, good price, and streaming unblocking (although not for Netflix), and this VPN is a solid choice. (See our full review of CyberGhost.)
When it comes to servers, more is always better. More servers mean that you're less likely to be shunted into a VPN server that is already filled to the brim with other users. NordVPN, Private Internet Access, and TorGuard currently lead the pack with well over 3,000 servers each—NordVPN is at the forefront with 5,130 servers. But the competition is beginning to heat up. Last year, only a handful of companies offered more than 500 servers, now it's becoming unusual to find a company offering fewer than 1,000 servers.
Instead of logically tying the endpoint of the network tunnel to the physical IP address, each tunnel is bound to a permanently associated IP address at the device. The mobile VPN software handles the necessary network-authentication and maintains the network sessions in a manner transparent to the application and to the user. The Host Identity Protocol (HIP), under study by the Internet Engineering Task Force, is designed to support mobility of hosts by separating the role of IP addresses for host identification from their locator functionality in an IP network. With HIP a mobile host maintains its logical connections established via the host identity identifier while associating with different IP addresses when roaming between access networks.
With the service, user data cannot be intercepted as all traffic are encrypted. A split tunneling functionality allows users to route traffic from specific applications through the software. It likewise has a kill switch, which effectively cuts off Internet connection when the VPN connection fails. This prevents the accidental revelation of IP addresses.
Protocol: When you’re researching a VPN, you’ll see terms like SSL/TLS (sometimes referred to as OpenVPN support,) PPTP, IPSec, L2TP, and other VPN types. We asked Samara Lynn, Lead Analyst for Networking and Small Business at PCMag, whether or not a user shopping for a VPN should shop for one over another. “SSL is what is commonly used these days. All of these protocols will provide a secure connection,” she explained, and pointed out that most solutions are invisible to the end-user anyway. Strictly, each protocol has its benefits and drawbacks, and if you’re concerned about this (specifically, PPTP vulnerabilities,) you’re probably already aware of them. Most users don’t need to be concerned about this—corporate users on the other hand, are probably all using IPSec or SSL clients anyway.
Every service we tested accepts payment via credit card, PayPal, and Bitcoin. That’s plenty of options for most people, and you can always use a prepaid debit card if you don’t want your billing information tied to your VPN account. IVPN and OVPN are the only ones to accept cash payment through the mail, if you really don’t want to make a payment online. Private Internet Access and TorGuard accept gift cards from other companies—IVPN doesn’t, but that option isn’t worth the additional hassle for many people when other secure, private methods are available.
