Opera VPN works only through the Opera web browser, and it shouldn't be used for sensitive communications. Once very fast, Opera's VPN connections were painfully slow in our most recent tests. The Opera VPN mobile apps, which were full-fledged VPN services that performed decently in our 2017 tests, unfortunately closed up shop at the end of April 2018. There's one good feature, though: Opera VPN streamed Netflix successfully from all of its server locations (there are only three of them), which is more than many paid VPN services can do.
A powerful VPN service, Hotspot Shield is ideal for those who enjoy using public Wi-Fi. It is basically a free VPN that comes in the form of an application or as a browser extension. Security is assured as the service uses OpenVPN , which makes use of the same encryption as HTTPS does. This feature is particularly effective in protecting credit card information during online purchases.
Beyond those two factors, it’s difficult to make blanket statements about what makes a trustworthy VPN. At the bare minimum, a good VPN provider should not collect and keep any logs of its customers’ browsing history. If it does, that puts your privacy at risk should someone access (or even release) those logs without authorization. But deciding when to a trust a logging policy isn’t easy. As the EFF points out, “Some VPNs with exemplary privacy policies could be run by devious people.” You don’t need to have done anything illegal to prefer that law enforcement and criminals alike not have access to a browsing history that may include your bank, medical websites, or that one thing you looked at around 2 a.m. that one time.
One major limitation of traditional VPNs is that they are point-to-point, and do not tend to support or connect broadcast domains. Therefore, communication, software, and networking, which are based on layer 2 and broadcast packets, such as NetBIOS used in Windows networking, may not be fully supported or work exactly as they would on a real LAN. Variants on VPN, such as Virtual Private LAN Service (VPLS), and layer 2 tunneling protocols, are designed to overcome this limitation.
We’ve shown you how to build your own VPN for remote gaming and browsing that also protects your security, shown you how to make a VPN even more secure, and shown you dozens of services that operate free and paid VPNs you can sign up for and use. We’ve even put the question to you several times to tell us which VPN service providers you think are the best. So how do you pick a solid VPN service?
When purchasing VPN service from a provider, consider what platform you will use. Do you want to use mobile devices or your computer? If you travel a lot and the use of mobile devices such as smartphones or tablets is important to you, then ensure that your chosen VPN host supports such a connection or even provides apps for your specific mobile devices.
Not all mobile VPN apps are created equal. In fact, most VPN providers offer different services (and sometimes, different servers) for their mobile offerings than they do for their desktop counterparts. We're pleased to see that NordVPN and Private Internet Access provide the same excellent selection of servers regardless of platform. These apps received an Editors' Choice nod both for desktop VPN apps and Android VPN apps.
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.)
Early data networks allowed VPN-style connections to remote sites through dial-up modem or through leased line connections utilizing Frame Relay and Asynchronous Transfer Mode (ATM) virtual circuits, provided through networks owned and operated by telecommunication carriers. These networks are not considered true VPNs because they passively secure the data being transmitted by the creation of logical data streams. They have been replaced by VPNs based on IP and IP/Multi-protocol Label Switching (MPLS) Networks, due to significant cost-reductions and increased bandwidth provided by new technologies such as digital subscriber line (DSL) and fiber-optic networks.
When you're accessing the internet via Wi-Fi, do you worry about the safety of your data—and about who else might be spying on that data as it passes over the air, or even stealing it? If not, you're sadly in the high-risk majority. You really ought to be using a virtual private network, or VPN. In fact, however, when PCMag ran a survey on VPN usage, we found that a surprising 71 percent of our 1,000 respondents had never even used a VPN. Even among those who support net neutrality—who you might think would be better informed on security and privacy issues—55 percent had never used a VPN.
