It usually relies on either Internet Protocol Security (IPsec) or Secure Sockets Layer (SSL) to secure the connection. However, SSL VPNs can also be used to supply secure access to a single application, rather than an entire internal network. Some VPNs also provide Layer 2 access to the target network; these will require a tunneling protocol like PPTP (Point-to-Point Tunneling Protocol) or L2TP (Layer 2 Tunneling Protocol) running across the base IPsec connection.
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.
The NordVPN client provided one of the most attractive interfaces, and connecting to a VPN server was straightforward and very quick. We found performance to be somewhat spotty, however, with our fastest connection running at 53 Mb/s down and 26 Mb/s up, compared to 125 Mb/s down and 20 Mb/s with the VPN connection turned off. We did have an issue connecting to Netflix, but Amazon Prime Video ran without issue. Our other internet tests went without a hitch.

Best for Frequent Flyers (VPN Anywhere): The name Hide My Ass (HMA) speaks for itself and can protect your data, identity and ultimately your derriere in a variety of far-flung places. Owned by security software company Avast, the HMA Pro VPN service has an extraordinary geographic scope with 900 servers in 190 countries, including Russia and Albania. The VPN service can obscure your location, protect data traffic and shuffle its IP addresses for greater anonymity. It lacks a firewall or ad blocker, though. There’s software for PCs (Vista, 7, 8, 10) and Macs (OSX 10.5), iOS and Android systems as well as some open-source routers. An HMA account supports up to five simultaneous users. Its blue and white interface is small and lets you choose among Instant Mode (one-click connect), Location Mode (pick your server) or Freedom Mode (the closest free-speech friendly country). Unlike PIA, you select a user name. At $12 a month, it’s more expensive than PIA but a full year costs $5 a month. Its UK headquarters means that HMA’s logs should be beyond the reach of American spy agencies.
In this case, agencies see only the tunnel and not what is inside. They only get to view a single connection from a specific server and not who the user is, location or what is being downloaded or uploaded. VPN software also has the ability to provide agencies with user information or deny request for such. Such solution can be implemented as client and server software, hardware and software or on a subscription basis. There is also Secure Sockets Layer VPN, which enables remove users to connect by simply using a web browser.
Since we last tested VPNs, we've given special attention to the privacy practices of VPN companies and not just the technology they provide. In our testing, we read through the privacy policies and discuss company practices with VPN service representatives. What we look for is a commitment to protect user information, and to take a hands-off approach to gathering user data.
When choosing between protocols to connect to, consider how you are using your VPN. PPTP is known to be fast over wi-fi; however, it is less secure than L2TP and IPSec. So, if security is important to you, then consider using either L2TP or IPSec. If you are connecting to a VPN for work purposes, then your employer will most likely have a preferred protocol. If you are using a hosted VPN, then ensure that you use a protocol which they support.
Mullvad is not that easy to use, with a bare-bones desktop interface and, unlike every other VPN service we've reviewed, no mobile client apps. (You do get instructions on how to manually set up OpenVPN apps.) This service's network speeds were far from great in our tests, and it's fairly expensive, with no discount for paying yearly instead of monthly.
Something pretty great about Speedify is that you can use it for free without even making an account. The moment you install and open the software, you're immediately being protected behind a VPN and can do anything a user can, like change the server, toggle encryption on and off, set monthly or daily limits, and easily connect to the fastest server.
IVPN was one of the fastest providers when we tested US servers using the Internet Health Test. Our budget pick, TorGuard, was faster, but it defaults to the less secure 128-bit encryption. Our non-VPN connection tested at roughly 300 Mbps down. Some tested services are not listed because connection failures prevented some of our tests from completing.

Corporate and Exit Locations: Depending on what you’re using a VPN for, your service’s location—and the exit locations you can choose—are important to consider. If you want to get around a location restriction and watch live TV in the UK, for example, you want to make sure your VPN service provider has servers in the UK. If you’re concerned about privacy or state-sponsored snooping, you may want to pick a service operated outside of your home country. Similarly, if the service is based on the US, they’re subject to US laws, and may be forced to turn over usage data to the authorities upon request. Many people make more of this than they should (we’ve seen overseas services turn over their data to friendly governments without any hesitation repeatedly), but it’s important to make sure a VPN has servers in multiple locations—or at least the location you’re interested in—when shopping.
Hotspot Shield VPN works in most countries, but that doesn’t mean it’s always legal to use a VPN in a specific country. If you have any doubts about the legality of using a VPN in a certain country, always consult a qualified lawyer because laws can change quickly. If you’re still unsure, then it’s best to play it safe and abide by the most conservative guidelines of a country.
It's also notable that ExpressVPN is able to gain access to Netflix, which some (like PureVPN) are not able to do. Like PureVPN, ExpressVPN is one of the best for getting around roadblocks in China (though there are only servers in 94 countries), and has up to 256 bit encryption. Get one month for $12.95, six months for $9.99/month, or a one-year subscription for $8.32/month. You would be paying around $10 more per month compared to any other VPN, but the quality is definitely there — and if you're really not happy, you can get your money back within the first 30 days. Another cool thing: You can pay with Bitcoin.

Mobile VPNs are designed and optimized to ensure a seamless user experience when devices are switching networks or moving out of coverage. It generally has a smaller memory footprint, and because of that, it also requires less processing power than a traditional VPN. Therefore, it enables your applications to run faster while the battery pack is able to last longer.
TorGuard is incorporated in St. Kitts and Nevis, and operates out of offices mostly in the US. But most people shouldn’t be worried about the legal jurisdiction of their VPN’s offices—we detail the reach of government surveillance above. In short, we think a privacy-focused VPN with public leadership that can be trusted not to collect information about their customers is a better choice in any country, rather than an opaque company run from the most liberty-ensuring country on the planet.

Since it takes research to find out if a VPN service has a history of good or bad behavior, we’ve done the legwork to find the best VPN out there. In order to win our seal of approval, the service has to protect online privacy; allow you to keep anonymity; offer a good variety of locations from which to direct your traffic; offer fast, reliable performance; and provide an easy-to-use interface.

The client is uniform across every device I have used (Windows, Android, and Amazon FireOS). I would like to say I was quite happy that ExpressVPN is one of the few VPNs (that seem trustworthy) that actually had a client in the Amazon App Store for the Fire tablets. No more need for sideloading, manual updates, or sketchy OpenVPN clone clients. At first the speeds weren't the greatest on the "Smart Location" server (New York). These speeds capped at about 12Mbps down and 10Mbps up. I have 150Mbps/15Mbps service. After hunting for other servers I found a few that provide roughly 60Mbps/15Mbps service throughout the US and Canada. DNS Leak tests were successful in that I am not leaking.
We're not cryptography experts, so we can't verify all of the encryption claims providers make. Instead, we focus on the features provided. Bonus features like ad blocking, firewalls, and kill switches that disconnect you from the web if your VPN connection drops, go a long way toward keeping you safe. We also prefer providers that support OpenVPN, since it's a standard that's known for its speed and reliability. It's also, as the name implies, open source, meaning it benefits from many developers' eyes looking for potential problems.

"Following an audit by Leon Juranic of Defense Code Ltd., hide.me are now certified completely log-free. Even free users are no longer subject to data transfer logs. What’s more, hide.me has recently begun publishing a transparency report of requests by authorities for information on users of their service; as they say on their website, their standard response to such requests is to state that, as they keep no logs, they are unable to provide any such information."

Hide My Ass! is one of the more expensive VPN providers going. On a rolling monthly basis, you’ll be paying £7.99 a throw, while a £59.88 annual subscription is equivalent to paying £4.99 a month. As we said above, if you need a VPN service with a huge number of endpoints across the globe, then Hide My Ass! is the VPN for you. Otherwise, you might be better off looking elsewhere.
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.
VPNArea is one of the few providers that offer dedicated IP addresses in various countries around the world, as listed on their website. They also allow account sharing and permit six simultaneous connections per subscription. VPNArea continues to improve and remains an excellent choice for privacy-focused users. Check out their discount pricing for annual plans. [Learn more >]
Generally speaking, transfer speed tests via NordVPN’s UK endpoints continue to impress, with FTP downloads clocking 10.4MB/s (83Mbit/s) and HTTP downloads at 10MB/s (80Mbit/s). However, we saw unusually slow FTP results from our Dutch reference server, at an anomalous 5.1MB/s (40.8Mbit/s), compared to an HTTP download at 9.9MB/s (79.2Mbit/s). That said, U.S. speeds have improved on previous tests, coming in at around 3.5MB/s (28Mbit/s) for both FTP and HTTP transfers.

If you’re seriously concerned about government surveillance—we explain above why that should be most people’s last consideration when choosing a VPN—some expert sites like privacytools.io recommend avoiding services with a corporate presence in the US or UK. Such experts warn about the “14 eyes,” a creepy name for a group of countries that share intelligence info, particularly with the US. IVPN is based in Gibraltar, a British Overseas Territory. We don’t think that makes you any worse off than a company based in Switzerland, Sweden, or anywhere else—government surveillance efforts around the world are so complicated and clandestine that few people have the commitment, skills, or technology to avoid it completely. But because Gibraltar’s status has been a topic of debate in other deep dives on VPNs, we’d be remiss if we didn’t mention it.


CyberGhost is transparent about its company structure, posting photos and bios on its website of everyone from the CEO to the cleaning lady, and privacy fanatics will like that the company is based in Romania rather than the U.S. But CyberGhost's full-service subscription price is among the most expensive month by month — it's far better to just pay for a year at a time.

VPN technology was developed as a way to allow remote users and branch offices to securely access corporate applications and other resources. To ensure safety, data travels through secure tunnels, and VPN users must use authentication methods -- including passwords, tokens or other unique identification procedures -- to gain access to the VPN server.
I have been using PIA for two years now. Actually, I was really skeptic when I first went to the website. It had a stock photo of a family, shady "we are the best" text all around. But hey, I subscribed to give it a try. And it worked wonderful. PIA has been an incredibly solid, fast and reliable VPN provider for me through 2 years. Never had an issue with them whatsoever.
How much will it cost? If price is important to you, then you may think that a free VPN is the best option. Remember, however, that some VPN services may not cost you money, but you might “pay” in other ways, such as being served frequent advertisements or having your personal information collected and sold to third parties. If you compare paid vs. free options, you may find that free VPNs:

Welcome to the CNET 2019 Directory of VPN providers. In this directory, we're taking a look at a few of the very best commercial VPN service providers on the Internet like CyberGhost, IPVanish, Hotspot Shield, Private Internet Access and others. Rather than looking at the wide range of free providers, which often have a lot of limits (and dubious loyalties), we are looking at those vendors who charge a few bucks a month, but put your interests first, rather than those of shadowy advertisers and sponsors. Our VPN rankings are based more than 20 factors including number of server locations, client software, dedicated and dynamic IP, bandwidth caps, security, logging, customer support and price.
