Today, the Internet is more accessible than ever before, and Internet service providers (ISPs) continue to develop faster and more reliable services at lower costs than leased lines. To take advantage of this, most businesses have replaced leased lines with new technologies that use Internet connections without sacrificing performance and security. Businesses started by establishing intranets, which are private internal networks designed for use only by company employees. Intranets enabled distant colleagues to work together through technologies such as desktop sharing. By adding a VPN, a business can extend all its intranet's resources to employees working from remote offices or their homes.

[...] VPNs using dedicated circuits, such as Frame Relay [...] are sometimes called trusted VPNs, because customers trust that the network facilities operated by the service providers will not be compromised.
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.
It’s in 148 locations, each with varying numbers of servers. ExpressVPN’s network spans 94 countries, which is unmatched by most competitors. It covers every continent except Antarctica, with solid coverage in Asia and Africa. Some servers in exotic locations, such as Vientiane or Algier, are virtual, though, so beware if you’re concerned with security.
VPNs initially are corporate networks ensuring safely encrypted connections between the company server and the employees. These systems give colleagues who are in different departments the possibility of collaborating without physical contact. VPNs are helpful and assist in office maintenance by allowing their employees to work from anywhere in the world or remotely in the comfort of their homes. The application and use of VPN technologies were started by the Chinese who were after getting the around the restrictions of the great firewall.
It can be quite simple to watch Netflix and other restricted goodies. You'll have to use a VPN service that allows you to get a unique IP address. This can often be available for an additional fee. Look for VPN services that offer a "dedicated IP address", "dedicated IP", or "static IP." Additional features like these will always allow you to access content from Netflix through a VPN 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.
A proxy server is another way to conceal your real location. By transferring data through a proxy server the data appears to be going to that server, not you - so for example if you’re in the US and the proxy is in Switzerland, the website or service will think it’s talking to a machine in Switzerland. The main difference is that VPNs protect all your traffic while proxies tend to be limited to specific types of data, such as peer to peer networking or web browsing. 
Some hit streaming sites like Netflix, BBC iPlayer, and Amazon Prime impose geo-restrictions (Read complete guide on vpn for amazon prime), which limit users from other countries to access streams. Connecting to a secure VPN in a supported country gives you access to these geo-restricted platforms. Subsequently, you can enjoy watching your favorite TV shows/movies, minus the hassle.
Things can get tricky when it comes to trusting a VPN. Recently, PureVPN handed over log information the company had to federal investigators building a case against a cyberstalker and general dirtbag. Some were surprised that the company had any information to hand over, or that it did cooperated with investigators at all. It seems to us that PureVPN stayed within the bounds of its stated privacy policy. But it's also true that other companies, such as Private Internet Access, aren't able to connect any of your personal information to your account information.
CyberGhost operates an ample network of more than 1,200 servers, including 20 in Australia and more than 200 in the US. It has a strong focus on unblocking streaming services like Netflix and Amazon Prime Video. It’s also popular with torrenters and has a dedicated “Torrent Anonymously” option within its apps. Plus, speeds are excellent, making it a great all-rounder. CyberGhost doesn’t log user activity or record IP addresses. Apps are available for Windows, MacOS, iOS, and Android.
ExpressVPN is based in the Birtish Virgin Islands, and has expanded to a global company, that boasts with fasts speed and that is still one of the most secure VPN services out there. That might be true considering that the DNS Leak Protection is tested and it does cover IPv4, IPv6 and WebRTC protocols. The encryption protocols it uses are top notch and the service is available on almost all modern and well-known platforms:
IVPN also performed well in our speed tests. Though it wasn’t always the fastest in the 54 measurements we took on each service, it ranked near the top on many servers at different times of the week—especially compared with the most trustworthy services. Private Internet Access, one of the most visible, privacy-focused VPNs, had slower speeds when connecting to most servers and less reliable connections than IVPN. For US servers (which we expected to be the fastest locations since we tested from California), IVPN ranked behind only OVPN and TorGuard. We liked OVPN—especially its speed results—but we thought that company’s small team and small selection of servers and locations were too limiting for some people. (Read more in the Competition section.) Though TorGuard edged out IVPN in this test, the difference wasn’t big enough to affect our everyday browsing. And because we tested each application at its default settings, TorGuard’s faster speeds were partially thanks to its default 128-bit encryption; IVPN offers only more secure, but often slower, 256-bit encryption.
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.
Setting up ExpressVPN and connecting to a VPN server was easy enough. Performance, when connected to the VPN server, was average at 49 Mb/s down and 16 Mb/s up, compared to our usual speeds of 125 Mb/s down and 20 Mb/s up. Netflix complained about a proxy being in use when we used the automatic configuration option, but it worked fine when we manually selected a local U.S. server. Amazon Prime Video played just fine, and our other internet tests completed without issue.
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.
Dang, "complete BS service" is pretty harsh. We did see some positive comments from users mentioning that they didn't have these problems. Others also mentioned that it's a good idea to test out every VPN service with a money-back guarantee just to see how they work, because why not? Unless you're in China — CyberGhost servers are apparently not the greatest there. Get one month for $12.99, one year for $5.25/month, two years for $3.69/month, or three years for $2.50/month. (There is a free version, but Reddit users warn to not even think about it.)
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.

Once on the public internet, those packets travel through a bunch of computers. A separate request is made to a series of name servers to translate the DNS name to an IP address. That information is sent back to your browser, which then sends the request, again, through a bunch of computers on the public internet. Eventually, it reaches the ZDNet infrastructure, which also routes those packets, then grabs a webpage (which is actually a bunch of separate elements), and sends all that back to you.
To narrow the hundreds of VPN providers down to a manageable list, we first looked at reviews from dedicated sites like vpnMentor and TorrentFreak, research and recommendations from noncommercial sources such as That One Privacy Site and, and user experiences and tips on various subreddits and technology-focused websites like Lifehacker and Ars Technica. We settled on 32 VPNs that were repeatedly recommended. From there, we dug into the details of how each one handled issues from technology to subscriptions:
If your VPN will primarily support remote users such as telecommuters and traveling employees and these users will access internal LAN resources that use a Network Address Translation (NAT) address rather than a routable IP address, you might have problems with some vendors' VPN products. NAT lets multiple internal network hosts use nonroutable IP addresses to access the Internet through one IP address on a firewall or router. This arrangement provides an additional level of security and lets a company be much more flexible with its address assignments than if it used real IP addresses for all its hosts.

Trust and transparency issues are the foremost concerns in choosing a great VPN, and if a service doesn’t have enough locations to be useful to you, all the security features won’t make a difference. But after those concerns have been satisfied, we recommend that most people use connections based on the OpenVPN protocol, because of security flaws and disadvantages in the PPTP and L2TP/IPsec protocols. (Experienced users may consider IKEv2, but because it has its own debated pros and cons, we ruled it out.) Though AES 128-bit encryption is fine for most purposes, we prefer services that default to the more-secure 256-bit encryption and still offer good performance.
ExpressVPN is based in the British Virgin Islands which, although a British Overseas Territory, isn’t beholden to the strict data retention laws of the UK’s Investigatory Powers Act. If you’re after anonymous payment options, you can buy your subscription with bitcoin if you wish – and if you don’t want to, then ExpressVPN has a clearly stated no-logging policy. This has been put to the test by the Turkish authorities, who seized endpoint servers last December, and found no logs.
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.

"ISPs are in a position to see a lot of what you do online. They kind of have to be, since they have to carry all of your traffic," explains Electronic Frontier Foundation (EFF) senior staff technologist Jeremy Gillula. "Unfortunately, this means that preventing ISP tracking online is a lot harder than preventing other third-party tracking—you can't just install [the EFF's privacy-minded browser add-on] Privacy Badger or browse in incognito or private mode."
The well-publicized case of the intruder who cracked Microsoft's VPN, accessed the corporate network, and almost made away with the company's precious source code should be a warning. VPNs offer many benefits but also open a hole into your network, usually bypassing your firewall or going right through it. So, you need to carefully consider which VPN product to choose and how to install and run it.
Some virtual networks use tunneling protocols without encryption for protecting the privacy of data. While VPNs often do provide security, an unencrypted overlay network does not neatly fit within the secure or trusted categorization.[citation needed] For example, a tunnel set up between two hosts with Generic Routing Encapsulation (GRE) is a virtual private network, but neither secure nor trusted.[24][25]
Avast SecureLine VPN offers good overall performance and steady connections, and it was the best of the limited-feature services we tested in 2017. But at $80 per year for software installation on five devices, it's more expensive than any full-fledged VPN service that doesn't limit installations. A single Mac or PC license is $60, while iOS or Android licenses are $20 each.
Probably PPTP's biggest advantage is that it lets you create an easy and inexpensive VPN between two Windows computers (e.g., in a RAS or Routing and Remote Access connection). PPTP also doesn't have the NAT-related problems that I mentioned earlier and works with non-TCP/IP protocols such as IPX. So if you're on a tight budget and you need minimal security, PPTP is certainly better than nothing. But even the budget conscious have other alternatives. Windows XP and Windows 2000 support IPSec natively, and I recommend it over PPTP.
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.
This is when the VPN uses a gateway device to connect to the entire network in one location to a network in another location. The majority of site-to-site VPNs that connect over the internet use IPsec. Rather than using the public internet, it is also normal to use career multiprotocol label switching (MPLS) clouds as the main transport for site-to-site VPNs.
