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.
UK FTP and HTTP performance with CyberGhost hovered just under 5MB/s (40Mbit/s). Testing endpoints in the Netherlands yielded around 7MB/s (56Mbit/s), while in the United States, we managed just 2MB/s (16Mbit/s). This is passable for standard web browsing and video streaming but could be a bottleneck if you have a fast internet connection and want to download large files while connected to your VPN. These scores are slightly slower than they were earlier in the year – remember that any speed test only provides a snapshot of a brief period of time.
If you are interested in an added level of protection, there are intriguing gadgets called Tiny Hardware Firewalls. These devices range from about $30 to $70 and connect via a network port or a USB slot to your laptop. They make the initial network connection, and so your computer's communication is always blocked before it calls out to the internet.
IVPN excels at trust and transparency, the most important factors when you’re choosing a virtual private network. After interviewing IVPN’s CEO, we’re convinced that IVPN is dedicated to its promises not to monitor or log customer activity. But a trustworthy VPN is only as good as its connections, and in our tests IVPN was stable and fast. IVPN apps are easy to set up and use with secure OpenVPN connections on Windows, macOS, Android, iOS, plus a few other platforms. Extra features like automatic-connection rules and kill switches to block data on unsecured connections add protection and value that make it worth a slightly higher price than some competitors.
Our VPN-issued IP address was never blacklisted by websites like those of Yelp and Target, but we were unable to access Netflix and BBC iPlayer while connected to TorGuard. No VPN offers a reliable way to access these streaming services, though: All of the VPNs we tried were blocked by Netflix, and of the four that could access BBC content on the first day, two were blocked the next.
When purchasing VPN service from a provider, consider whether you will access content outside the country you physically are located in. When you browse the internet, you have an address which shows where you are. This is called an “IP address.” If you try to access content in another country, your IP address may not allow you to do so because there may not be an agreement between that country and yours about the legal rights of the content. However, you can use a VPN host with “exit servers” which will show your IP address as being within that country. Thus, you will be able to access the content in another country by using the exit servers. When picking a VPN host in order to do this, you’ll want to look at the locations of your host’s servers in order to ensure that they have servers in the country where you want to access content.
We didn’t find any problems when we tested other aspects of TorGuard’s performance. Each time we checked our location via IP address, it accurately resolved to the location of a TorGuard server. Neither our true IP address nor our location was exposed when we tested for DNS leaks and IPv6 leaks. TorGuard runs its own DNS servers—a requirement for all the VPNs we tested—so the routing that happens when you go to a website isn’t released to your ISP, Google, or anyone else. And since TorGuard doesn’t support IPv6, the app disables it completely, just like IVPN.
The VPN services market has exploded in the past few years, and a small competition has turned into an all-out melee. Many providers are capitalizing on the general population's growing concerns about surveillance and cybercrime, which means it's getting hard to tell when a company is actually providing a secure service and when it's throwing out a lot of fancy words while selling snake oil. In fact, since VPN services have become so popular in the wake of Congress killing ISP privacy rules, there have even been fake VPNs popping up, so be careful. It's important to keep a few things in mind when evaluating which VPN service is right for you: reputation, performance, type of encryption used, transparency, ease of use, support, and extra features. Don't just focus on price or speed, though those are important factors.
We tested Private Internet Services using its Windows installer, which configures the VPN protocols and provides a simple utility in the task bar to turn the VPN connection on and off. While the interface was spartan, performance was excellent. Our test system consistently maintained over 110 Mb/s download and 19 Mb/s upload speeds with the VPN connection turned on, very close to our usual 125 Mb/s download and 20 Mb/s upload speeds.
To be fair, not all pay VPN services are legitimate, either. It's important to be careful who you choose. Over on ZDNet's sister site, CNET, I've put together an always up-to-date directory of quality VPN providers. To be fair, some are better than others (and that's reflected in their ratings). But all are legitimate companies that provide quality service.
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.
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.
Mobile Apps: If you’re going to spend money on a VPN service provider (or even if you use a free one, frankly), you should be able to get a consistent experience across all of your devices. Most prominent providers offer desktop and mobile solutions for individual users, and while corporate and school networks may be a bit behind the curve here, they’re catching up too. Make sure you don’t have to use two different VPNs with two different policies and agreements just because you want to secure your phone along with your laptop.
Despite Proton’s strong reputation for privacy with both its VPN and Mail services, we previously dismissed ProtonVPN without testing because it didn’t offer native applications for major operating systems. Instead, the service relied on third-party applications that could be clumsy to set up and lacked important features. Now that ProtonVPN apps are fully supported on Windows, Mac, and Android, we’re looking forward to testing the service for the next update.
The student/worker. This person has responsibilities to attend to, and uses a VPN provided by their school or company to access resources on their network when they’re at home or traveling. In most cases, this person already has a free VPN service provided to them, so they’re not exactly shopping around. Also, if they’re worried about security, they can always fire up their VPN when using airport or cafe WI-Fi to ensure no one’s snooping on their connection. Photo by Ed Yourdon.
Kaspersky Secure Connection is one of the fastest VPNs we’ve tested to date. We recorded UK speeds of 12.13MB/s (97.04Mb/s) via FTP and 10.27MB/s (82.16 Mb/s) via HTTP and 10.5MB/s (84Mb/s) and 9.39MB/s (75.12Mb/s) respectively for FTP and HTTP. The US VPN connection was so fast that we repeatedly re-tested it in case of errors or anomalies, because it more than tripled our non-VPN’d connection speed with 9.57MB/s (76.56Mb/s) downloads over both FTP and HTTP.
While a VPN can aid privacy and anonymity, I wouldn’t recommend fomenting the next great political revolution by relying solely on a VPN. Some security experts argue that a commercial VPN is better than a free proxy such as the TOR network for political activity, but a VPN is only part of the solution. To become an internet phantom (or as close as you can realistically get to one), it takes a lot more than a $7 monthly subscription to a VPN.
With hundreds of VPN services and clients available, it can be difficult to decide which one to use. We've extensively tested several popular VPN services that met three requirements: They had both desktop and mobile client software (with one exception), they had VPN servers in many countries, and they offered unlimited data use, at least in their paid versions.
If you're using a service to route all your internet traffic through its servers, you have to be able to trust the provider. Established security companies, such as F-Secure, may have only recently come to the VPN market. It's easier to trust companies that have been around a little longer, simply because their reputation is likely to be known. But companies and products can change quickly. Today's slow VPN service that won't let you cancel your subscription could be tomorrow's poster child for excellence.
Speed-wise, when connected to VPNHub’s UK and Netherlands endpoints, our FTP and HTTP downloads came in at around 10MB/s (80Mbit/s). Connecting to U.S. endpoints gave us 4.8MB/s (38.4Mbit/s) via FTP and 4.2MB/s (33.6Mbit/s) via HTTP. While that’s good enough for everyday browsing and streaming, your results may vary – we connected to U.S Netflix no problem, but, as with many VPNs on this list, BBC iPlayer promptly showed us the door.
Natively on your operating system with the built-in VPN functionality (no apps required). Many operating systems natively support VPNs: Windows, Mac OS, Android, and iOS. To use this you will need to import your VPN’s configuration files onto your device. This will use the IPSec/IKEv2 or IPSec/L2TP protocols, rather than OpenVPN, since OpenVPN can only be used through apps. (PPTP is also sometimes supported, but this VPN protocol is not recommended due to security vulnerabilities.)
Private Tunnel only has endpoints in 12 countries, including the UK, Japan, the Netherlands, Sweden and the USA, where it’s based and it’s terms of service also state that it collects also log files “for monitoring server performance, identifying software bugs, identifying any potential security breaches, and for the purpose of identifying abusive users”.
