Voluntary tunneling occurs when a client computer or routing server creates a virtual connection to the target tunnel server. To accomplish this, tunneling client software and the appropriate tunneling protocol must be installed on the client computer. For the protocols discussed in this technical reference, voluntary tunnels require an IP connection (either LAN or dial-up).
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.
A traditional VPN can affect the user experience when applied to wireless devices. It's best to use a mobile VPN to avoid slower speeds and data loss. A mobile VPN offers you a high level of security for the challenges of wireless communication. It can provide mobile devices with secure access to network resources and software applications on their wireless networks. It's good to use when you're facing coverage gaps, inter-network roaming, bandwidth issues, or limited battery life, memory or processing power.

Free VPN services are generally subpar when compared to premium providers, or they’re posited as a ‘trial’ version of the service. Most aim to retain their customer base by getting them to upgrade to the full-fat version, but a free version is still better than browsing without one. On the other hand, lots of free users also help to give a company legitimacy; especially if they’re dropping down five star reviews like it’s going out of fashion. Offering a solid free service is a great way to get some positive attention, and the market is fairly crowded.


We spent more than 130 hours researching 32 VPN services, testing 12, interviewing the leadership of five, and consulting information security and legal experts. We found that a VPN shouldn’t be your first step toward online security, but for protecting your info on public Wi-Fi (and in some other cases), IVPN is the most trustworthy provider that offers fast, secure connections and easy setup.
Password Authentication Protocol (PAP) is a clear-text authentication scheme. The NAS requests the user name and password, and PAP returns them in clear text (unencrypted). Obviously, this authentication scheme is not secure because a malicious user could capture the user's name and password and use it to get subsequent access to the NAS and all of the resources provided by the NAS. PAP provides no protection against replay attacks or remote client impersonation once the user's password is compromised.
The Overplay Smart DNS service, on the other hand, routes internet connection using a different DNS to give the illusion that one is located in a different country, without significant speed reduction. This is very useful to those who want to access sites that are blocked in their own countries. The service supports PCs, Apple TV, iPhone, iPad, Wii, PS3, XBOX360, among other devices.
Security when connecting to public Wifi networks: Many people use public Wifi networks – You can find them in airports, cafes, bars and public libraries for example. People use these Wifi networks freely and without any forethought for their security. How do you know that network is secure? How do you know there isn’t someone attempting to break into that network? A VPN can be used to securely connect to a Wifi network and protect your data integrity. Learn More
A firewall uses packet filtering to allow or disallow the flow of specific types of network traffic. IP packet filtering provides a way for administrators to define precisely what IP traffic is allowed to cross the firewall. IP packet filtering is important when private intranets are connected to public networks, such as the Internet. There are two approaches to using a firewall with a VPN server:
It is possible for some background services to send information across that initial, unsecured connection before the VPN loads. To be fair, the risk is relatively minor for most usage profiles. If you're establishing a connection automatically to your corporate server, you will definitely want to check with your IT team about how they want you to set things up.
CyberGhost, Romanian-based VPN that stands out as a free service without any restrictions. While reviewing Cyberghost VPN we found that the service is transparent with no hidden agendas of keeping logs or information. The company offers 1319+ servers across 61 countries; isn’t the network is larger enough to fulfill all our streaming needs. The company has secured its position in the VPN industry recently, with its feature-rich yet easy-to-use software, AES 256-BIT Encryption protocols and offers seven simultaneous connection.
It can be made to work at a push in China but there’s better options available. Customer support is improving. IPVanish isn’t cheap but it only requires a 2-year commitment to slash the monthly price by 69% to a reasonable $3.74. If P2P is your priority then IPVanish really is a superb VPN for both privacy and performance that will also cover many other needs.

Voluntary tunneling occurs when a client computer or routing server creates a virtual connection to the target tunnel server. To accomplish this, tunneling client software and the appropriate tunneling protocol must be installed on the client computer. For the protocols discussed in this technical reference, voluntary tunnels require an IP connection (either LAN or dial-up).


My recommendation, and the protocol I most often choose to use, is OpenVPN. OpenVPN is a non-proprietary, open-source implementation of a VPN communication layer protocol. It's well-understood, well-regarded, generally quite secure, and robust. In addition, it has the benefit of being able to communicate over port 443, which is the standard port for https communication, which means almost all firewalls will allow OpenVPN traffic -- and most won't even be able to detect that a VPN is being used.
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.

At $7.50/month and $58.49 for a year, they're obviously trying to move you towards their yearly program. We awarded the company points for Bitcoin support, and their money-back guarantee. We're a little disappointed that they only allow a 7-day trial, rather than a full 30-days. The company is generous, with five simultaneous connections. They also picked up points for their connection kill switch feature, a must for anyone serious about remaining anonymous while surfing. 
The initial PPP payload is encrypted and encapsulated with a PPP header to create a PPP frame. The PPP frame is then encapsulated with a modified GRE header. GRE is described in RFC 1701 and RFC 1702 in the IETF RFC Database and was designed to provide a simple, general purpose mechanism for encapsulating data sent over IP networks. GRE is a client protocol of IP using IP protocol 47.

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 it comes to VPNs, however, speed is one of the most difficult factors to accurately quantify. We always run speed tests as empirically as possible when we review a VPN provider, but the fact of the matter is that the fastest VPN for where you live is not necessarily the fastest VPN for where I live. The fastest VPN for streaming video might not be the speediest for online gaming. Even the fastest VPN service at noon probably isn’t the quickest at midnight.
When you're using a public Wi-Fi network, even a password-protected one, a VPN is your best friend. That’s because using public hotspots can be rife with hazards. From man-in-the-middle attacks to Wi-Fi sniffing, there are many different hacking methods that snoopers use to intercept your Internet traffic and steal your social media or banking passwords, files and photos.
Express VPN is certainly one of the best VPN services companies that can be found in the market. It is considered as one of the most powerful providers regarding encryption and concealment of IP addresses. This has been proven since it has passed the test of Great Chinese Firewall, one of the most demanding tests and that most suppliers do not exceed. ExpressVPN.com has servers in more than 100 cities in 78 countries on all continents.
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.
Another reason you might choose to use a VPN is if you have something to hide. This isn't just about folks doing things they shouldn't do. Sometimes people really need to hide information. Take, for example, the person who is worried he or she might be discriminated against by an employer because of a sexual preference or medical condition. Another example is a person who needs to go online but is concerned about revealing location information to a person in their life who might be a threat.

When you download a file from a server without a VPN, there’s a chance you will encounter network congestion, most likely on your nearby ISP network or at the download server itself. When you use a VPN service, you add a third potential bottleneck to the route. Whether because of server load or congestion on the network surrounding the server, there’s a higher chance that your speed will be affected while connected to a VPN.
What a VPN does do is make it much harder for an attacker to simply hoover up your information along with hundreds or thousands of others. That alone can help protect you from many of the large attacks and mass surveillance that have defined the last few years. Digital security, after all, is often really about economics. Spies and attackers would much rather go after the low-hanging fruit than try to crack or circumvent a VPN connection. Just remember that using security tools isn't an excuse for not also using a healthy dash of common sense.
So, having stated that, there are VPN protocols that are fast (implies no, or minimum encryption) and some are slow (implies stronger encryption). PPTP is a protocol which is one of the less secure but fastest protocols out there. Similarly, other protocols such as OpenVPN or L2TP/IPSec are way more secure. So, it all comes down to your own priorities. Do you want more speed or more protection? And if you want best of both worlds, we have already suggested Fast VPN providers that have all the options and protocols to get accustomed to your priorities.
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.
Most VPN providers don’t give you the option, anyway, but don’t disable encryption altogether. Additionally, 128-bit AES is the minimum strength encryption necessary for a VPN to do its job and keep your data safe. It’s effectively un-crackable and is slightly faster than 256-bit AES, which is also common. A handful of VPNs use Blowfish encryption, which tends to be slower than its AES counterpart. We recommend at least 448-bit Blowfish encryption if you go that route.
As a business grows, it might expand to multiple shops or offices across the country and around the world. To keep things running efficiently, the people working in those locations need a fast, secure and reliable way to share information across computer networks. In addition, traveling employees like salespeople need an equally secure and reliable way to connect to their business's computer network from remote locations.
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.
Split tunneling is the generic term for software that lets you define which apps send data through the VPN tunnel and which travel outside the tunnel. This lets you route more sensitive activities, like web browsing or online banking, from more mundane but higher-bandwidth activities, like streaming music or playing video games. It's especially useful because Netflix blocks VPN use, as do other services. You can simply route these apps outside the VPN in order to avoid this problem. Not many VPN services offer this feature, but PureVPN does. Seek out split tunneling if speed is of primary concern.
Cost: There are two plans here; Premium and Gold, but only the latter supports VPN while the other is just their DNS service. UnoTelly Gold costs $7.95/month if you buy it every month, but there are three other options if you want to purchase it for three months, six months, or one year. Those prices, respectively, are $6.65/month, $6.16/month, and $4.93/month (each, of course, being paid for in one lump sum). You can try it free for eight days through this link.
Hello Nathan, We are sorry for all the inconvenience you've experienced. Bunch of different factors might interfere with how VPN works: antivirus systems, firewalls, router settings, previous VPN services installed play their role just to name a few. Your mentioned behavior is uncommon, in most cases couple of mouse clicks is enough to get our apps up and running; however sometimes additional troubleshooting is required. This is why our customer support team is available 24/7, they aim to provide our clients with the best possible experience and help in any way we can. Please don't hesitate and reach out to them in case of any future issue.
If you are depending on your VPN to keep your activities even mildly anonymous, you need some sense of security that the VPN isn’t just going to go down and dump all your traffic out into the regular internet. What you want is tool known as a “kill switch system”. Good VPN providers have a kill switch system in place such that if the VPN connection fails for any reason it automatically locks down the connection so that the computer doesn’t default to using the open and unsecured internet connection.

Providers can also log less-specific data about when or how often you connect to your VPN service. In some cases, these logs are a routine part of server or account management, and can be responsibly separated and scrubbed. In other cases, VPN providers take note of every connection and use that information to actively police individual customers. Though it’s reasonable for companies to protect their networks from abuse, it becomes a dealbreaker when companies keep extensive connection data for a longer period of time. Some VPN companies we spoke with explained how a log might note your current connection for authentication purposes, but that log is deleted as soon as you disconnect. This kind of “live log” isn’t a concern, and even those culled every few hours—or as long as the end of each day—shouldn’t be confused with logs of your traffic and online destinations.
OVPN was regularly the fastest VPN in our tests regardless of the time of week or location. We also liked the app’s clean design and its simple and well-labeled settings pane. But OVPN is a small startup with a limited server network: At this writing, the company has servers in just seven countries, none in Asia. That makes it less versatile for finding less congested routes or geoshifting. OVPN also hasn’t released an Android app yet, so even non-iOS device owners will have to resort to the clunky, third-party OpenVPN Connect app on their phones. When we reached out for details about the company’s operational security, founder and CEO David Wibergh was open to questions and gave us answers that led us to believe that the company acted in the best interest of its customers’ privacy and security. He noted that after an uptick in data requests from local authorities in Sweden—all of which OVPN responded to by explaining that it lacked any pertinent data—the company published a blog post to detail just how little information it keeps.

Second on our list of fast VPN protocol is L2TP. It is more similar to PPTP protocol but with added layer of encryption that makes is more powerful in terms of security. L2TP/IPSec is easy to setup and considerably delivers high-speed VPN experience from any internet-connected devices. It comes built-in to Microsoft Windows, Android, and Apple devices. However, its offering is not extended to open-source routers and consoles. L2TP/IPSec is also considered as fast secure VPN protocol as it supports 256-bit encryption packets. The use of L2TP/IPSec protocol is more in practice for commercial uses to secure all the outgoing and incoming communication. It also acts as an alternative fast VPN protocol where PPTP fail to perform due to firewalls.
Free VPN services are generally subpar when compared to premium providers, or they’re posited as a ‘trial’ version of the service. Most aim to retain their customer base by getting them to upgrade to the full-fat version, but a free version is still better than browsing without one. On the other hand, lots of free users also help to give a company legitimacy; especially if they’re dropping down five star reviews like it’s going out of fashion. Offering a solid free service is a great way to get some positive attention, and the market is fairly crowded.
If the VPN server is behind a firewall, packet filters must be configured for both an Internet interface and a perimeter network interface. In this scenario, the firewall is connected to the Internet, and the VPN server is an intranet resource that is connected to the perimeter network. The VPN server has an interface on both the perimeter network and the Internet.
VPN protocols play a significant role in connection speed. A VPN offers PPTP, L2TP, SSTP and OpenVPN protocol, all of them are dedicated to bypassing geo restrictions. PPTP and L2TP protocols are undoubtedly the fastest VPN protocols among all, but it depends on the location you are connected from. If you are experiencing slow VPN speed, then try switching between different protocols to ameliorate your VPN connection and turn it into a high-speed VPN.
Using a VPN, all data traffic is confined to a private, encrypted tunnel until they reach the public Internet. Destinations cannot be accessed until after the end of the VPN tunnel is reached. VPN services are quite useful in workplaces, especially for those who use mobile devices in accessing data from a work server. However, the most common use of VPN software is to remain anonymous to ISPs, websites or governments. This is true for users who download files illegally, such as in the case of copyrighted torrent files.
A traditional VPN can affect the user experience when applied to wireless devices. It's best to use a mobile VPN to avoid slower speeds and data loss. A mobile VPN offers you a high level of security for the challenges of wireless communication. It can provide mobile devices with secure access to network resources and software applications on their wireless networks.

Our VPN reviews instead stress value and technical excellence. The number of devices that can be used with an account is, in our opinion, more important. We also prefer VPN services with lots of servers and a good geographic distribution of those servers. VPNs that are easy to set up and use for first timers and include a well-made local client also go a long way toward getting PCMag's endorsement. And, of course, price is a major issue. The average monthly price of a VPN right now is $10.48. If a VPN is charging more, it had better be offering something compelling.
I am traveling very soon to South East Asia to attend conferences in multiple countries. You have put to gather a detailed article on fastest vpns, but what would you suggest I should use? I am really confused between express and nordvpn. A friend of mine recommended express, but it seems a bit expensive. I don’t know anything about nordvpn, but it seems like a good deal. While you have put PureVPN number one on your list, I have had mixed experience with them. Last time I tried it, I faced frequent disconnections on my iphone. What’s your take on nordvpn and expressvpn? Pls reply.
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.
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.
If you’re looking for something free, look no further. If StrongVPN and SurfEasy are like like a solid mid-class sedan, TunnelBear is more like the econo-car (if you buy a TunnelBear subscription) or the city bus (if you use their generous free program). That’s not a knock on TunnelBear, either–they’ve been around for years and their free service tier has been of great utility to people in need all over the world.
You can also use a remote VPN server to spoof your location. For example, you could be sitting in Chicago and select a VPN server in Australia. Your traffic would then make a trip down under before continuing as normal. To people trying to track you, you'd appear to be surfing from Australia. This is especially useful if you're keen to access region-locked streaming content. If you connect to a server within the UK, free BBC TV streaming is suddenly available to you in the United States. It's also a useful tool for when you are connecting in countries that have strict or repressive internet regulations. Always be clear on the laws of the land and any terms of service you might be running up against by doing so, however.
One basic test for a VPN service is to check how long a VPN client takes to connect to a VPN server and get online. For our 2018 reviews, we installed each vendor's VPN client software on an HP EliteBook x360 1020 G2 laptop running Windows 10, an iPad mini and a Samsung Galaxy S8 Android phone. (In 2017, we used a Lenovo ThinkPad X1 Yoga notebook, an Apple MacBook Air, a Samsung Galaxy S6 phone and the iPad mini.) We used each device with each VPN service we tested.
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.
TunnelBear VPN is a free service that constantly impresses people. This VPN is super-secure and even opened up its software to a third-party analysis last year. The outcome? Security researchers found the VPN to be secure and reliable. It also keeps no logs. Unfortunately, The service is restricted to just 500MB per month. Despite this, it is brilliant for locations with severe censorship and where privacy is essential. It is perfect for securely unblocking news.
Secure connections for business: For businesses who operate at multiple nationwide locations, or for employees who travel on the road, a VPN can provide a fantastic means of security. Instead of connecting to your work network via the public internet, you can instead connect via the FreeVPN.se connection. This will encrypt your data, hide your devices IP address and ensure that any sensitive business information remains untouched and private. Learn More
Ironically, in many cases, the faster your standard internet connection, the more speed you “lose” in percentage. Even if you have a 50 Mbps connection and this interconnection is poor, you probably won’t be able to make the best of the VPN service. For example, if you have a 5 Mbps connection, you’ll lose just 10-20% of bandwidth, but if you have 100 Mbps, connecting to a VPN may cause you to lose more than a half of your speed.
Increasingly, mobile professionals who need reliable connections are adopting mobile VPNs.[32][need quotation to verify] They are used for roaming seamlessly across networks and in and out of wireless coverage areas without losing application sessions or dropping the secure VPN session. A conventional VPN can not withstand such events because the network tunnel is disrupted, causing applications to disconnect, time out,[30] or fail, or even cause the computing device itself to crash.[32]
ProtonVPN is available on all your devices including PC, MacOS, mobile, and even your router. A secure internet connection which you can trust is essential every day - for your PC at home, for your mobile device on the road, or your workstation at the office. ProtonVPN works on Windows, macOS and Android via our application, or on iOS, using any OpenVPN client.

Being in the industry for long, HideMyAss needs no introduction. It is unfair not to include them in our fastest VPN speed test, and with no surprise, they made it to the list! HideMyAss offers a wide range of servers in over 190 countries (I’m sure they will have all 196 soon) with over 930 VPN servers. Their fast VPN servers are optimized in a way to deliver top speed to cater all type of VPN needs. HIdeMyAss works on all the internet-connected devices and also offer simultaneous connectivity packed with high-speed VPN connection. HideMyAss VPN is easy to use and you don’t need any technical knowledge to operate their VPN connection. 30-day money back guarantee is also an advantage as they promise to give you money back if you are satisfied with their service. Read our complete HideMyAss VPN review here to get an in-depth understanding of the VPN provider. Here are the VPN speed results we gathered during the test:
Because it is impossible to update separate user accounts on separate servers for the same user simultaneously, most administrators set up a master account database at a domain controller or on a RADIUS server. This enables the VPN server to send the authentication credentials to a central authenticating device, and the same user account can be used for both dial-up remote access and VPN-based remote access.
VPNs can be either remote-access (connecting a computer to a network) or site-to-site (connecting two networks). In a corporate setting, remote-access VPNs allow employees to access their company's intranet from home or while travelling outside the office, and site-to-site VPNs allow employees in geographically disparate offices to share one cohesive virtual network. A VPN can also be used to interconnect two similar networks over a dissimilar middle network; for example, two IPv6 networks over an IPv4 network.[6]

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.
ZenMate has a lightweight app that is really simple to use. It offers good security and connects with any server of your choice almost instantly. The speeds remain fairly stable across servers and is faster than dozens of other VPNs. I would recommend its free browser extensions, as there are better premium apps available for lower rates than ZenMate.
Borders still exist on the web, in the form of geographic restrictions for streaming content. The BBC iPlayer, for example, lets UK residents watch the Beeb to their heart's content. The rest of the world, not so much. But if you were to select a VPN server in the UK, your computer's IP address would appear to be the same as the server, allowing you to view the content.
