Among the most critical is how to communicate and exchange information securely between employees sitting at multiple locations. Here is where a VPN or a Virtual Private Network proves to be very handy. It is a fast, reliable, and secure way to exchange information across computer networks, and an excellent, secure mode of communication from remote locations.
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.
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.
Hotspot Shield VPN does not log your browsing activity. Almost all Internet Service Providers (ISPs) track your browsing history. So when you use a VPN like Hotspot Shield, there is no record of the websites you have visited and which apps you use. This prevents hackers from exploiting vulnerabilities in these websites/apps to get to your personal information.
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.

For example, when your computer is connected to a VPN, the computer acts as if it's also on the same network as the VPN. All of your online traffic is transferred over a secure connection to the VPN. The computer will then behave as if it's on that network, allowing you to securely gain access to local network resources. Regardless of your location, you'll be given permission to use the internet as if you were present at the VPN's location. This can be extremely beneficial for individuals using a public Wi-Fi.
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. 
VPNs secure your traffic and route it through an intermediary server so it can’t be traced. But if privacy is not of chief concern to you, then there are other alternative proxy methods that offer faster speed. A SOCKS proxy, for example, does pretty much the same thing as a VPN without the encryption. Without having to encrypt and decrypt traffic, SOCKS proxy users can get faster speeds and still mask their IP address.
The best VPN services offer a robust balance of functions, server location, connectivity protocols, and price. Some are great for occasional use, others are geared towards surrounding location constraints that companies place on their apps and services, and others are focused on people who download a lot of content and want some privacy while they do.
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).
Proxies are also widely used, and there is always the question about how they differ from VPNs. The purpose of both methods is to protect the identities of the users or to falsify a place. While they are different technologies, many VPN providers also offer proxies.A proxy is the type of computer system that functions as an intermediary for your connected device and your web connection. These servers also have their own IP addresses, so the transfers cannot be traced directly to your computer.
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 because 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.
Because the firewall does not have the encryption keys for each VPN connection, it can only filter on the plaintext headers of the tunneled data, meaning that all tunneled data passes through the firewall. However, this is not a security concern because the VPN connection requires an authentication process that prevents unauthorized access beyond the VPN server.
Instead of logically tying the endpoint of the network tunnel to the physical IP address, each tunnel is bound to a permanently associated IP address at the device. The mobile VPN software handles the necessary network-authentication and maintains the network sessions in a manner transparent to the application and to the user.[30] The Host Identity Protocol (HIP), under study by the Internet Engineering Task Force, is designed[by whom?] to support mobility of hosts by separating the role of IP addresses for host identification from their locator functionality in an IP network. With HIP a mobile host maintains its logical connections established via the host identity identifier while associating with different IP addresses when roaming between access networks.

A VPN, or virtual private network, is not a magic bullet for online privacy, but it may be a useful tool in some circumstances. A VPN encrypts all the Internet traffic between your computer and the VPN server, preventing anyone on your local network, or connection points along the way, from monitoring or modifying your traffic. Beyond the VPN server (in other words, on the rest of the way to whatever Internet server you're connecting to), your traffic mixes with traffic from other people on the VPN and the rest of the Internet. Ideally, that makes your traffic traceable only to the VPN server, not to your home, office, or computer. Though the extra steps and encryption layers slow down any Internet connection, the best VPN providers have connections that are speedy enough to keep browsing and online services snappy.
One of the most common types of VPNs used by businesses is called a virtual private dial-up network (VPDN). A VPDN is a user-to-LAN connection, where remote users need to connect to the company LAN. Another type of VPN is commonly called a site-to-site VPN. Here the company would invest in dedicated hardware to connect multiple sites to their LAN though a public network, usually the Internet.
VyprVPN offers the fastest VPN download for Windows, Mac, Android, iOS, TV and Router, enabling you to secure your desktop and mobile devices in seconds while receiving the fastest connection speeds around. Download the fastest VPN service with apps that are secure, easy-to-use and reliable. VyprVPN also includes time-saving features like one-click connect, one-tap server selection and a ping test to choose the fastest server.

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
Everyone wants to keep their browsing activity safe and secure, but not at the expense of compromising on speed, right? This is where a fastest VPN service comes in. But why there’s a need for a fast VPN, don’t you trust your Internet provider? This WHY has multiple answers, but the best to quote here is that VPN slows down the internet, seriously? Yes, depends on the VPN you’re using. People all around the world use VPN services not only for their security but for various other entertainment purposes like streaming and downloading torrents. They look for the fastest VPN which not only keeps their browsing activity safe but also let them be the fastest on the radar.

Cost: You have three pricing options depending on how often you want to pay. The cheapest IPVanish plan is to buy a full year at once for $77.99, making the monthly rate $6.49/month. If you pay for three months at once for $26.99, the monthly cost comes down to $8.99/month. However, to subscribe on a monthly basis with no commitment, it will cost $10/month.


Multi-hop cascades + NeuroRouting – Perfect Privacy’s apps give you the ability to create multi-hop VPN cascades across up to four different servers in the network. This protects you against the possibility of a rogue data center logging traffic, targeted monitoring, and other threat scenarios. Additionally, the NeuroRouting feature takes this concept further by dynamically routing all traffic through multiple hops in the server network, corresponding to the location of the site you’re visiting. (No other VPN offers this.)
Advanced leak protection – Perfect Privacy offers very secure apps to ensure you are protected against any and all leaks. In the Perfect Privacy review I discuss the three different levels of the kill switch and DNS leak protection. Users are also protected from IPv6 leaks because Perfect Privacy offers full IPv6 support across their server network (giving you both an IPv4 and IPv6 address for all your devices).

This awesome Malaysian VPN provider has an excellent free service. Although users are limited to just three server locations (Singapore, the Netherlands, and Canada), users get a whopping 2GB per month of free use at up to 80Mbps. When reviewing hide.me, we found the lack of server locations means it isn’t good for unblocking content from all over the world. If you need US or UK servers, please look elsewhere. On the plus side, this VPN has a strong privacy policy and provides robust encryption to keep your data secure.


The available speed for each client is unlimited since VPN Express does not impose any restrictions. It is important to clarify that the speed obtained in the navigation will vary according to different parameters such as the own internet provider or the actual physical distance between the client and the chosen server. In terms of downloads, it can be said that they are also unlimited and the provider supports P2P.
NordVPN also nudged out ExpressVPN in terms of speed, with a few caveats. Most VPN apps select a location, and then the app automatically selects the best server in that location. NordVPN is not so good at this. The auto-select on a couple occasions put us on servers that were complete duds, which resulted in a test result so bad it qualified as a statistical outlier and had to be thrown out. Thankfully, the app allows you to manually select a specific server and view the load capacity on all servers, where we had much better luck. Servers are optimized for specific streaming channels, torrenting, or security measures.
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.

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.


An OSPF-routed network can be subdivided into areas, which are collections of contiguous networks. All areas are connected together through a common area called the backbone area. A router that connects an area to the backbone area is called an area border router (ABR). Normally, ABRs have a physical connection to the backbone area. When it is not possible or practical to have an ABR physically connected to the backbone area, administrators can use a virtual link to connect the ABR to the backbone.
We also like how easy it is to connect, and how clear and accessible the settings are, on all platforms when using the IVPN app. (ChromeOS has an option to use a less-secure VPN protocol with most providers, including IVPN. But TorGuard, our budget pick, supports the more secure OpenVPN on Chromebooks and tablets.) If you do want to tweak some settings, IVPN has easy-to-understand checkboxes for most options. For example, the kill switch (labeled “firewall”) has an easy on/off toggle. Anytime it’s on and the app is open, all traffic in and out of your computer will cut off if you forget to connect to the service or the secure connection drops for some reason.

There is a PPTP control connection between the IP address of the PPTP client using a dynamically allocated TCP port and the IP address of the PPTP server using the reserved TCP port 1723. The PPTP control connection carries the PPTP call control and management messages that are used to maintain the PPTP tunnel. This includes the transmission of periodic PPTP Echo-Request and PPTP Echo-Reply messages to detect a connectivity failure between the PPTP client and PPTP server. PPTP control connection packets consist of an IP header, a TCP header, a PPTP control message, and a data-link trailer and header as shown in the following figure:

To stress-test the VPN services, we do things a little differently. Instead of letting Ookla find the best (read: closest) test server, we select a specific test server in Anchorage, Alaska, for both the VPN testing and the baseline test. We then connect to a VPN server in Australia, and calculate a percent change between the two. Usually, this results in a noticeable impact on latency as well as download and upload speeds. It helps give a sense of how the VPN would perform when you're traveling abroad or using the VPN to spoof your location.
The router could be running outdated and compromised firmware. The router could actually be malicious and actively sniffing packets and logging your data. The router could be improperly configured and other users on the network could be sniffing your data or probing your laptop or mobile device. You never have any guarantee whatsoever that an unknown Wi-Fi hotspot isn’t, either through malice or poor configuration, exposing your data. (A password doesn’t indicate a network is secure, either–even if you have to enter a password, you could be subject to any of these problems.)
Latency is a measurement of time between when your computer sends a request and when it receives a response. It's often called ping time. Lots of things can affect latency; the distance your request physically travels through fiber has a big impact, for example. Latency is measured in milliseconds, however, so even a large increase may not be noticeable to the average user. Latency is very important when playing video games over a VPN, as lower latency means a more responsive experience with less lag.

But even if you know who’s behind your VPN, you shouldn’t trust a free one. A free service makes you and your data the product, so you should assume that any information it gathers on you—whether that’s an actual browsing history or demographics like age or political affiliation—is being sold to or shared with someone. For example, Facebook’s Onavo provides an encrypted connection to Onavo’s servers like any VPN, shielding you from the prying eyes of your ISP or fellow network users. But instead of promising not to examine, log, or share any of your traffic, Onavo’s privacy policy promises the opposite. Covering the service, Gizmodo sums it up well: “Facebook is not a privacy company; it’s Big Brother on PCP.” Facebook collects information about your device, other applications you use, and even “information and other data from your device, such as webpage addresses and data fields.” And the company “may combine the information, including personally identifying information, that you provide through your use of the Services with information about you we receive from our Affiliates or third parties for business, analytic, advertising, and other purposes.” That means Facebook can collect anything it wants, and sell it to anyone it wants.
NordVPN is one of those service providers that not only focus on security but super-fast VPN experience also. Within a short span of time, it has managed to come in the limelight and have been praised by many experts and got featured on highly-reputable websites like PCMag, Forbes, and The Huffington Post. With over 550 servers plotted in 49 counties, NordVPN easily made its way to our fastest VPN service list. Their servers are capable of bypassing intense geo-restriction with high-speed VPN experience. We had the chance to get help from their support team, and they set a new benchmark of proactive customer services experience. And yes, 30-day money back guarantee is another thing that is much of a consideration when you are in search for a fast VPN service, and they have it! Read more on NordVPN review and learn how they delivery top speed.
The downsides to the free plan are that you'll see more ads, at least on the Android app, your choice of connections will be limited to Hotspot Shield's U.S. servers and you won't be able to get around geographic restrictions on Netflix, Hulu or BBC iPlayer. We were also a bit annoyed that the desktop software tries to hide the free plan when you launch it for the first time.
Microsoft Challenge Handshake Authentication Protocol (MS-CHAP) is an encrypted authentication mechanism very similar to CHAP. As in CHAP, the NAS sends a challenge, which consists of a session ID and an arbitrary challenge string, to the remote client. The remote client must return the user name and an encrypted form of the challenge string, the session ID, and the MD4-hashed password. This design, which uses the MD4 hash of the password, helps provides an additional level of security because it allows the server to store hashed passwords instead of clear-text passwords or passwords that are stored using reversible encryption. MS-CHAP also provides additional error codes, including a password-expired code, and additional encrypted client-server messages that permit users to change their passwords during the authentication process. In MS-CHAP, both the client and the NAS independently generate a common initial encryption key for subsequent data encryption by MPPE.
The first step to security is usually a firewall between the client and the host server, requiring the remote user to establish an authenticated connection with the firewall. Encryption is also an important component of a secure VPN. Encryption works by having all data sent from one computer encrypted in such a way that only the computer it is sending to can decrypt the data.
The Shiva Password Authentication Protocol (SPAP) is a reversible encryption mechanism employed by Shiva Corporation. A computer running Windows XP Professional uses SPAP when connecting to a Shiva LAN Rover. A Shiva client that connects to a server running Routing and Remote Access also uses SPAP. Currently, this form of authentication is more secure than plaintext but less secure than CHAP or MS-CHAP.
Torrenting/P2P Support – IPVanish makes all torrent websites and clients accessible. There is no problem with IPVanish as far as support for P2P networking is considered. However, the fact that IPVanish is based in the US and subject to its laws makes it a poor choice if your main purpose of having a VPN is to download torrents. This is because companies have no power against agencies and if they are trying to monitor a specific user, the company would probably have no choice but to comply and leak user data. In short, do not use IPVanish for torrenting to ensure your safety.

As used in this context, a VPLS is a Layer 2 PPVPN, rather than a private line, emulating the full functionality of a traditional LAN. From a user standpoint, a VPLS makes it possible to interconnect several LAN segments over a packet-switched, or optical, provider core; a core transparent to the user, making the remote LAN segments behave as one single LAN.[16]

PIA didn’t score super high. Total was really fast when I first tested it, probably because it had few customers and the servers weren’t congested, but since then the service has taken a nose dive both on the performance and the customer service front. We had a never-ending stream of comments on their review about poor billing practices and other major issues, so we can no longer recommend it.
IVPN doesn’t have as many server locations as larger services like ExpressVPN do. When we initially recommended the service, IVPN was limited to 13 countries, compared with ExpressVPN’s 94. But in the months since, IVPN has doubled that to 26, including two additional locations in Asia (Tokyo and Singapore). We’ve yet to test the new servers though, and in the past, IVPN’s single location in Asia—Hong Kong—was slower than competitors.
VPNs help enable users working at home, on the road, or at a branch office to connect in a secure fashion to a remote corporate server using the Internet. From the users perspective, the VPN is a point-to-point connection between the user's computer and a corporate server. The nature of the intermediate network, the Internet, is irrelevant to the user because it appears as if the data is being sent over a dedicated private link.
As Internet security has become paramount in today’s world, more and more companies have been adopting VPN software. As a matter of fact, the global VPN market is expected to grow at a CAGR of 13% by the end of 2022 and reach $106 billion. This growth is seen to be driven by the growth of the cyber security sector, the increase in the number of security proliferation, the growth of industries and increase in the use of mobile devices. However, this projections could be hampered by high deployment cost and lack of technical skills.
Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) is an EAP type that is used in certificate-based security environments. If smart cards are used for remote access authentication, EAP-TLS is the required authentication method. The EAP-TLS exchange of messages provides mutual authentication, negotiation of the encryption method, and encrypted key determination between the remote access client and the authenticator. EAP-TLS provides the strongest authentication and key-determination method.
To help ensure confidentiality of the data as it traverses the shared or public transit network, it is encrypted by the sender and decrypted by the receiver. Because data encryption is performed between the VPN client and VPN server, it is not necessary to use data encryption on the communication link between a dial-up client and its Internet service provider (ISP). For example, a mobile user uses a dial-up networking connection to dial in to a local ISP. Once the Internet connection is made, the user creates a VPN connection with the corporate VPN server. If the VPN connection is encrypted, there is no need to use encryption on the dial-up networking connection between the client and the ISP.

Server switching is a feature -- offered by most VPN service providers -- that allows you to change what region or country you're going to connect to. Most providers allow you to switch as often as you'd like (although you usually have to disconnect, then change your configuration, and reconnect). This may be useful if you're trying to hide your location, or if you're running into some communications glitches on the server you're currently using.
Anonymous internet access: Anonymity is preferable for many when surfing the web. We do not like the idea of someone watching our every more and monitoring our actions. We have a basic right to privacy and free VPN will help you achieve this. Using the VPN service, you can enjoy a trouble-free private browsing session with no traceability. Learn More
One of today’s leading VPN providers and another worthy mention on our list of top 20 VPN services, PureVPN is known for its service quality and customer support. The service has 450 servers in 101 countries, allowing users to surf the Internet and use any online solution without having to reveal their IP address. This is very useful to those who want to bypass Internet censorship.
One of the most popular VPN services in the market, HideMyAss has a myriad of features that are sure to attract anyone who wants online anonymity. It uses a variety of servers that work with any operating system or mobile device. Aside from PPTP and OpenVPN protocols, the service supports L2TP, which is more difficult to block. Ideal for getting around censorship and firewalls.
Osama is a staunch believer in the inalienable right of every citizen to freedom of expression. Writing about online privacy and security without regard to political correctness is his answer to the powers that be threatening our freedom. Deeply curious about Nature and the Universe, he is fascinated by science, intrigued by mathematics, and wishes to play guitar like Buckethead in some alternate version of reality.
Ideally, every VPN service provider would subject itself to independent audits to verify that it logs and operates as it claims. Right now, audits aren’t common practice in the VPN industry, though there’s a push to change that. Joseph Jerome, policy counsel at the Center for Democracy & Technology, told us about that group’s efforts to bring transparency to the VPN industry: “We would like to see security audits released publicly so security researchers can review them and attest to their veracity, as well as learn from the issues being identified.” The few companies we found that currently performed these types of audits had other dismissal-worthy failings, despite their valiant efforts toward transparency. And while such reports may increase your confidence when you’re shopping, there’s no guarantee that an audit makes a VPN service trustworthy: In other industries, conflicts of interest have led auditors and rating agencies (PDF) to miss or ignore major problems.
There is only one reason the company got a 4.5 rating instead of a full five. That's because they do log connection information, although kudos for their clarity in explaining exactly what they do and don't log. We like that they offer a 30-day refund policy.  They got bonus points because, important for some of our readers, PureVPN supports bitcoin payments.That said, if you don't mind the slight dings on privacy and refunds, you're going like their blazing fast performance. Also, you can grow with them. If after some time, you need to scale up to business-level plans, the company has offerings for growth. Pricing is middle-of-the-road,at $10.95 per month and $69.00 for three year's service.Finally, we like that PurVPN has both Kodi and a Chromebook solution called out right on their Web page. In addition, PureVPN earns the distinction of being the first VPN service we've seen to fully implement the GDPR.
