A VPN client on a remote user's computer or mobile device connects to a VPN gateway on the organization's network. The gateway typically requires the device to authenticate its identity. Then, it creates a network link back to the device that allows it to reach internal network resources -- e.g., file servers, printers and intranets -- as though the gateway is on the network locally.

Despite some of the drawbacks, ZorroVPN is a very interesting service if you are looking for advanced online anonymity. With their OpenVPN file config generator, you can create unique VPN chains with the Tor network and proxies (up to four hops). Unlike with Perfect Privacy, however, these multi-hop configurations cannot be dynamically changed within the VPN client.

Like most well-known VPN companies, IVPN supports a variety of privacy groups and causes. Pestell told us he worked with the Center for Democracy & Technology to improve trust in VPNs with a handful of transparency initiatives before they were announced. Neena Kapur of The New York Times (parent company of Wirecutter) information security team noted that IVPN’s leadership transparency and its relationship with CDT were significant pluses that contributed to its trustworthiness. Pestell was also the only representative we spoke with to offer to arrange for one of our experts to audit the company’s server and no-logging policies.1 We cover trust issues with VPNs at length elsewhere in this guide, but we believe that IVPN takes an active role in protecting its customers’ privacy and is not a dude wearing a dolphin onesie.


In many cases, each of these offices also have LANs. But how do the LANs connect? For some very specialized solutions, companies lease private lines to connect the offices. That can be very expensive. Instead, most companies opt to geographically connect separated private LANs over the public internet. To protect their data, they set up VPNs between offices, encrypting the data as it traverses the public internet.
We'll go into greater explanation about these three metrics and how we collect them below. But choosing which is most important is tricky. Mostly, it depends on how you're using your internet connection. We assume that most people reading are major consumers of content. Reading the news, streaming movies, using BitTorrent, or listening to music on the web all require that your device pull down data more or less continuously. With that in mind, we've settled on download speeds as the most important benchmark.
A lot of people avoid using VPN providers based out of the United States on the premise that US law would compel those providers to log all VPN activity. Counterintuitively, there are no such data logging requirements for US-based VPN providers. They might be compelled under another set of laws to turn over data if they have any to turn over, but there is no requirement they even keep the data in the first place.
TorGuard’s signup and payment process is also fine but not stellar. Compared with that of IVPN, the checkout process is clunky, and using a credit or debit card requires entering more personal information than with our top pick. The easiest option for anonymous payments is a prepaid debit card bought locally. Otherwise, like most providers, TorGuard accepts a variety of cryptocurrencies, PayPal, and foreign payments through Paymentwall. That last service also allows you to submit payment through gift cards from other major retailers. We don’t think this method is worth the hassle for most people, but if you have some money on a fast-food gift card you don’t want, turning it into a VPN service is a nice option.
We have also taken into consideration the use of VPN protocols in our fastest VPN trial. All the testing are on PPTP and L2TP connection as they are designed to yield fast VPN performance to the end users. All the high-speed VPN tests are carried out using Speedtest.net, a service that is used by almost everyone to test their internet connection. Below are the baseline speed of our Internet connection without a VPN:
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.

Mac users often told that they don’t need antivirus software because Mac is not prone to viruses; get a life man! This is not true at all, even the first well-known virus; Elk Cloner, affected Apple computers, not MS-DOS computers. Currently, the state of Mac malware is evolving, with more and more threats targeting the so-called impervious machines. We have already witnessed Mac threats appearance recently; on malwarebytes.com a mac user from Miami who had his DNS settings changed and were unable to change them back.


Jurisdiction – ZenMate is based in Germany, which is a country with one of the freest Internet in Europe. Online freedom is protected in the country and it does not have a history of persecution against bloggers and social media activists. Nonetheless, it is still part of the 14 Eyes alliance, which implies that users should be careful when considering ZenMate.
Beyond the CNET directory, it's always good practice to search "the Google" for a company or product name and read the user reviews. If you see a huge number of old complaints or new complaints suddenly start showing up, it might be that there's been a change of management or policies. When I'm looking for a service, I always base my decision partially on professional reviews and partially based on the tone of user reviews.
When we tested other aspects of IVPN’s performance, it also satisfied our requirements. On the default settings, our real IP address didn’t leak out via DNS requests or IPv6 routing, let alone a standard IP address checker. The DNS-requests check indicated that the app was using the company’s internal DNS servers and that they were correctly configured. None of the 12 services we tested disclosed our true IP address (though some showed mismatched IPs). Every VPN we considered had to operate its own DNS servers in-house and not rely on ISP servers or public options like Google’s, which give third parties a chance to log or analyze the sites you visit. IVPN currently disables all IPv6 connectivity, though the company is looking at solutions to securely support it soon. Most companies we considered do the same; OVPN was the only company to support IPv6 addresses at the time of our testing.
Torrenters use VPNs to hide their downloads and uploads, but are all VPNs suitable for BitTorrent? No, some don’t provide sufficient leak protection to protect you from copyright trolls, some are bad actors, and some don’t provide at all. If you want to enjoy private and protected torrenting, make sure your Torrent VPN is the best at its job. To figure out the fastest VPN for torrenting, let’s decide the criteria to judge them. Being a Torrent and P2P file sharer, what you want the most? Privacy, fast download speed, and no data caps, isn’t it?
Privacy features – The privacy features you want/need really varies for each person and depends on your threat model. For a higher level of online anonymity, you could use a multi-hop VPN, or possibly chain different VPN providers together. This could be done by using one VPN on a router, and then connecting through a second VPN on your computer. This can also be accomplished using virtual machines.

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.
Unlimited broadband enhances user experience. Another advantage is that you can use up to 5 devices on the same VPN account simultaneously. P2P sharing is allowed, since there is no control over what you do on the internet. Tailor-made applications for Windows, iOS and Linux work like tight clocks, but that’s not all. The interesting ‘door open’ tool searches for unlocked doors on other secure networks, so you do not need to be greedy and ask for the password in a hotel or buy a super-charged bottle at an airport terminal.
Switzerland is famed for its privacy-friendly legislation, and that’s where VyprVPN operates from - although its servers operate in 72 other countries to deliver unlimited data. If you’re used to VPN services absolutely killing your data speeds you’ll be positively surprised by VyprVPN: we found that our data speeds actually increased when we enabled the VPN! Not only that but there are plenty of useful options including auto-connect, a kill-switch and enhanced security via the service’s proprietary Chameleon protocol and its own DNS. VyprVPN has a free trial too so you can try it our and see what you think before you commit!

The biggest advantage of RIP is that it is extremely simple to configure and deploy. The biggest disadvantage of RIP is its inability to scale to large or very large networks. The maximum hop count used by RIP routers is 15. Networks that are 16 hops or more away are considered unreachable. As networks grow larger in size, the periodic announcements by each RIP router can cause excessive traffic. Another disadvantage of RIP is its high recovery time. When the network topology changes, it might take several minutes before the RIP routers reconfigure themselves to the new network topology. While the network reconfigures itself, routing loops might form that result in lost or undeliverable data.

If you’re going to use torrents, however, life is easier if you use a VPN—especially if the network you’re on blocks torrenting. There are many VPNs among our top picks that could be used for downloading torrents, but our preferred choice is Private Internet Access. This no-frills VPN has an absolute ton of servers, good speeds, and a nice amount of country locations to remain relatively anonymous. (Read our full review.) The price is right at less than $40 a year, and its privacy policies have been tested in court. Plus, advanced users can adjust their level of encryption for data encryption, data authentication, and handshake.
Servers – It is a bad idea to talk about the number of servers under NordVPN at any given point in time. This is because NordVPN’s server list is like my problems: they just never stop increasing! Currently, it is offering more than 4,700 servers, but don’t blame me if it adds a hundred more by the next day. There is no other VPN with a server network as large as NordVPN. As such, NordVPN comfortably ranks higher above all other VPNs when it comes to servers.
Protection of your IP address and private data: When surfing the web, there is no guarantee that your personal information is secure. Furthermore, when you go online, your IP address can be obtained – This creates a direct link back to your personal devices and can be used as a means of entry by hackers. free VPN hides your IP address and ensures there is no traceability back to you. Furthermore, your personal information and device will remain untouched. Learn More
Final Verdict – PIA is a reliable VPN service that only uses physical servers in its VPN network. It does not make any exaggerated claims of its qualities and clearly describes its policies and features. Moreover, the low price is another positive attribute of the VPN. In a nutshell, PIA is a VPN you can trust, though it is not an ideal VPN for torrenting.

ExpressVPN   has 148 locations in 94 different countries which means you can dial your IP address into 148 locations around the world. ExpressVPN delivers great performance - and it’s put the effort into its software too, with dedicated apps for Windows, Mac, Linux, iOS, Android and BlackBerry as well as some Smart TVs, Amazon Fire TV Sticks, Apple TV, PS4 and Xbox and even your router. Not only that but there are solid online tutorials too, so even if VPNs are dark magic to you they’ll have you up and running in no time. P2P is fully supported and it's super speedy so you can torrent using the maximum bandwidth of your broadband connection and there’s a kill switch that keeps your IP address hidden if anything goes wrong with the VPN or with your internet connection. ExpressVPN is reasonably priced, delivers a good service and has support for three simultaneous connections. There’s no free trial available but there is a no-fuss 30-day money back guarantee if the service doesn’t meet your requirements so that's a good way to test it out if you're unsure. We have used the 24/7 customer service a number of times and can vouch for its effectiveness - we had a couple of issues with using the service on a PC and were able to sort it within a few minutes using the instant online chat support.

As the size of the link state database increases, memory requirements and route computation times increase. To address this scaling problem, OSPF divides the network into areas (collections of contiguous networks) that are connected to each other through a backbone area. Each router only keeps a link state database for those areas that are connected to the router. Area border routers (ABRs) connect the backbone area to other areas.


The free tier gives you the Windows, Mac, iOS, Android and Amazon Fire TV/Firestick client software (and the beta Linux software, should you wish to try it); the Windflix feature to (try to) watch U.S. or U.K. Netflix streams; the Chrome, Firefox and Opera Windscribe browser extensions to block ads and trackers; a separate firewall built in to the Windows and macOS clients; and the ability to connect to VPN servers in 11 countries, mostly in Europe and North America.
A mix of features and price make a good VPN, but plenty of bad VPNs masquerade as good ones. Look for articles written by trustworthy sources that discuss the merits of each service based on its features, versus simple rundowns and user testimonials, which are almost always polluted by a combination of fanatical users and corporate bootstrapping in attempt to get their names out to potential customers.

Prices – ProtonVPN offers a free version with unlimited bandwidth. This makes it one of the few free VPN services with unlimited bandwidth. Its paid versions are categorized as Basic, Plus, and Visionary, each of which progressively offers more advanced features than the one before it. The basic version costs $4/month, while the Plus and Visionary plans cost $8/month and $24/month respectively. Yep, it is quite expensive.


The service has around a hundred servers around the world, in all continents. Server switching is facilitated on the line from just about anywhere. This feature is ideal for use by those who need to reach different locations or those who are in obscure places. Connection speed is relatively fast, with the service offering unlimited bandwidth. Albeit significant lag can be experienced during connection, such is resolved in just a few minutes.

We’re more than happy to help cut through all the jargon and ad copy to help get the bottom of things and, to that end, we’ve selected three VPN service providers that we have direct personal experience with and that meet our VPN selection criteria. In addition to meeting our outlined criteria (and exceeding our expectations for quality of service and ease of use) all of our recommendations here have been in service for years and have remained highly rated and recommended throughout that time.
IVPN exceeded our requirements for being trustworthy and transparent. It also offers good performance without sacrificing security, and it's easy to set up and use on nearly any device running Windows, macOS, Android, or iOS. Other VPNs we tested had faster connections at particular server locations or lower prices, but they came up short on essential factors such as transparency about who exactly runs them. If you're ready for a VPN, we think IVPN is worth the price, even considering competitors with cheaper options. If you're not ready to commit, you can try it out with a seven-day money-back guarantee. It's easy and obvious to turn off automatic billing, too.
In the past few years, I had terrible luck with VPNs... one provider didn't work with Netflix at all, and the other one very cluttered app interface which drove me crazy, so every time I used it, I felt frustrated. Now I'm testing Nordvpn. I'm not very trustful with big names, and its price seems too high for my pocket, but I thought I should give it a shot. In a few months of using Nord I didn't see any bugs or issues, so I feel that it's better to pay a few extra bucks but have a stable service like this, so in the long shot, it's totally worth the price I paid. Don't be afraid to invest, people.
Bandwidth restrictions might not have been a big deal in the pre-streaming era, but now that everyone is streaming videos, music, and more, the bandwidth burns up really fast. Avoid VPNs that impose bandwidth restrictions unless the bandwidth restrictions are clearly very high and intended only to allow the provider to police people abusing the service.
When a VPN server is in front of a firewall and connected to the Internet, inbound and outbound packet filters on the VPN server need to be configured to allow only VPN traffic to and from the IP address of the VPN server’s Internet interface. Use this configuration if the VPN server is in a perimeter network, with one firewall positioned between the VPN server and the intranet and another between the VPN server and the Internet.
In addition to hiding your online activity from a snooping government it’s also useful for hiding your activity from a snooping Internet Service Provider (ISP). If your ISP likes to throttle your connection based on content (tanking your file downloads and/or streaming video speeds in the process) a VPN completely eliminates that problem as all your traffic is traveling to a single point through the encrypted tunnel and your ISP remains ignorant of what kind of traffic it is.
VPNArea is one of the few providers that offers dedicated IP addresses in various countries around the world, as listed on their website. It also allows account sharing (six simultaneous connections permitted). VPNArea continues to improve and remains an excellent choice for privacy-focused users. Check out their discount pricing for annual plans. [Learn more >]

Final Verdict – NordVPN is easily one of the best all-around providers. I would especially recommend this VPN for users that value their privacy. The encryption protocols, jurisdiction, and logging policies of NordVPN make it the perfect VPN for users concerned about their privacy. And its Double VPN feature makes it stand out from the crowd, something I have covered in detail in NordVPN review.
VPN is used for a variety of purposes; from protecting your internet activity to giving you free and unmetered access to the Internet, it covers all! The fastest VPN is indeed a need for everyone using the Internet, as it is not only privacy and security that we seek but entertainment also. With a fastest VPN connection installed on your PCs and mobile devices, you can enjoy the greater goods of the Internet and seamlessly benefit from the fun with any restrictions. We have listed down some of the main advantages attached to a fastest VPN service.

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.
Tip for Chrome, Firefox, and Opera users: A feature called WebRTC can, in some Web browsers, inadvertently cause your true IP address to leak out even when you’re connected via a great VPN. WebRTC assists with peer-to-peer connections, such as for video chatting, but could be exploited in some cases. You can manually disable this function in Firefox, or use an extension to block most instances of it in Chrome or Opera. For more details and instructions, check out Restore Privacy.
L2TP uses UDP messages over IP networks for both tunnel maintenance and tunneled data. The payloads of encapsulated PPP frames can be encrypted or compressed (or both); however, L2TP clients do not negotiate the use of MPPE for L2TP connections. Encryption for L2TP connections is provided by IPSec Encapsulating Security Payload (ESP) in transport mode.
Before moving on to the fastest free VPN, which are quite a few; we would like to inform you that numerous vulnerabilities are attached with a free VPN. We are not recommending you to use freebies for privacy and security concerns, as free providers use weaker protocols and encryption levels, and sometimes they sell your data to the third party and even keep logs as well. However, if unblocking websites is the only benefit you want to gain out of a free VPN then check out these three fastest free VPN providers that perform better than others;
For inbound traffic, when the tunneled data is decrypted by the VPN server it is forwarded to the firewall, which employs its filters to allow the traffic to be forwarded to intranet resources. Because the only traffic that is crossing the VPN server is traffic generated by authenticated VPN clients, firewall filtering in this scenario can be used to prevent VPN users from accessing specific intranet resources.
Switzerland is famed for its privacy-friendly legislation, and that’s where VyprVPN operates from - although its servers operate in 72 other countries to deliver unlimited data. If you’re used to VPN services absolutely killing your data speeds you’ll be positively surprised by VyprVPN: we found that our data speeds actually increased when we enabled the VPN! Not only that but there are plenty of useful options including auto-connect, a kill-switch and enhanced security via the service’s proprietary Chameleon protocol and its own DNS. VyprVPN has a free trial too so you can try it our and see what you think before you commit!

In this approach, the firewall must be configured with input and output filters on its Internet and perimeter network interfaces to allow the passing of tunnel maintenance traffic and tunneled data to the VPN server. Additional filters can allow the passing of traffic to Web servers, FTP servers, and other types of servers on the perimeter network. As an added layer of security, the VPN server should also be configured with PPTP or L2TP/IPSec packet filters on its perimeter network interface as described in “VPN Server in Front of a Firewall” in this section.
This configuration is known as compulsory tunneling because the client is compelled to use the tunnel created by the FEP. Once the initial connection is made, all network traffic to and from the client is automatically sent through the tunnel. With compulsory tunneling, the client computer makes a single PPP connection. When a client dials into the NAS, a tunnel is created and all traffic is automatically routed through the tunnel. An FEP can be configured to tunnel all dial-up clients to a specific tunnel server. The FEP could also tunnel individual clients, based on the user name or destination.
Speedify's drawbacks are that you can't connect manually (it's software-based), the cellular-data usage will cut into your carrier's monthly limit, and it's based in the U.S. and subject to search warrants. The free services is limited to one device, although you could just try to create new accounts for extra devices. But even free users can connect to any of the 1,000 or so VPN servers in 40-odd countries.
ExpressVPN outranks quite a many VPN providers as it is well known for its overall remarkable performance. ExpressVPN speed is its unique selling proposition and it has one of the fastest VPN networks in the world. It comes handy both in delivering top speed and military-grade security. Having a wide range of servers located in 87 countries, ExpressVPN has this added advantage over its competitors. Although they don’t offer VPN free trial, their 30-day money back guarantee is superlative to all. It gives you enough time to use ExpressVPN for varied uses, hence to get satisfied with the performance. It also offers attractive features like the Zero-logging policy, unmetered bandwidth, multi logins, and unlimited switches that are considered as bliss for any VPN user. Below is the VPN speed test result for ExpressVPN, with and without a VPN connection. Read our complete ExpressVPN review here.
Compatibility – Device compatibility is something that has become more important with the passage of time. With an increased number of brands of computers and advances in mobile technology, virtually any software today should be compatible with various devices and operating systems. You should always make sure your VPN is compatible with your device before you make up your mind.
VPNs, or Virtual Private Networks, are a quick and easy solution to making your computer appear to be coming from a different location. They accomplish this by creating a virtual network that routes all of your PC or smartphone’s network traffic through an encrypted tunnel and out the other side, making it seem to the world that you’re actually in whatever location the VPN server is located. This can help you bypass geographic restrictions, avoid censors, or keep you (relatively) anonymous online.

When we looked at just iPhone VPNs last year, our results yielded a very different breakdown. In our tests on iOS, we found that Hide My Ass, Golden Frog Vypr VPN, KeepSolid VPN Unlimited, NordVPN, and PureVPN were the top performers. Hide My Ass and PureVPN dominated in the download speed tests, improving speeds by 10.1 and 6.8 percent, respectively.
It’s up to you to answer these questions by reading over the documentation provided by the VPN service provider before signing up for the service. Better yet, read over their documentation and then search for complaints about the service to ensure that even though they claim they don’t do X, Y, or Z, that users aren’t reporting that they are in fact doing just that.
Cost: StrongVPN offers two plan options: one month and annual. Their annual plan will give you the biggest bang for your buck, coming out to just $5.83 per month (if you pay $69.96 annually). Their monthly plan is $10. Fortunately, each tier comes with the same set of features, so you won’t get cheated out of certain levels of encryption depending on which plan you subscribe to.
The user’s certificate could be stored on the VPN client computer or in an external smart card. In either case, the certificate cannot be accessed without some form of user identification (PIN number or name/password credentials) between the user and the client computer. This approach meets the something-you-know-plus-something-you-have criteria recommended by most security experts.

Business security and strength. Businesses aren’t immune to hacking and someone getting into your system to access consumer records could be a catastrophe and lead to significant losses for everyone involved. Some businesses operate on multiple networks, potentially leaving entryways for thieves. Remote businesses are becoming the norm and employees could become targets for passage into large and secure systems. Using a VPN helps prevent such situations from happening, regardless of whether or not you’re on a public network. Your network will be encrypted, and your business will remain secure.
Jurisdiction – Gibraltar is territory that is controlled by the United Kingdom to some extent. Nonetheless, the internal affairs of the country are governed by itself. Censorship of certain websites is present in Gibraltar. As such, the jurisdiction of IVPN lies in a region with limited online freedom, but privacy in the region is still much better than in Europe.
Trust.Zone offers inconsistent speeds that vary considerably from one server to the other. Users might find it excellent for certain locations like the UK and Germany, but not fast enough for others. The privacy and security features of Trust.Zone are its strongest attributes, making it a great option for users seeking protection at acceptable speeds.
L2TP/IPsec (Layer 2 Tunneling Protocol with Internet Protocol Security): L2TP is not secure itself, so it's generally paired with the IPsec secure-networking standard. The combination of the two was once thought to be very secure when properly implemented, but some VPN services suggest that you use OpenVPN instead. L2TP/IPsec has native support in Windows, OS X/macOS, Android, Chrome OS and iOS. Most VPN services support it.
Servers – ExpressVPN has a large server network that spans more than 94 locations across the world. The total number of servers of ExpressVPN has crossed 2,000. You can connect to servers in available locations in a matter of mere seconds. All servers are encrypted with the AES 256 standard, ensuring the security of user traffic. With these servers, you can gain access to any website, no matter how strong a firewall has been put up to prevent user traffic from accessing it.
When we test VPNs, we generally start with the Windows client. This is often the most complete review, covering several different platforms as well as the service's features and pricing in depth. That's purely out of necessity, since most of our readers use Windows (although this writer is currently using a MacBook Air). We currently use a Lenovo ThinkPad T460s laptop running the latest version of Windows 10. We periodically upgrade to a newer machine, in order to simulate what most users experience.
