Servers – Boasting over 2,000 servers, PureVPN’s network is like a giant tentacle monster with multiple servers located in over 140 countries of the world! Geographically, PureVPN covers more locations around the world than any other VPN I have come across. You can choose to automatically connect to the best VPN server depending on the purpose you wish to use the VPN for or choose your own preferred server manually. It takes a relatively long time to connect to the server compared to other VPN providers, which is one of the downsides of this VPN. But as soon as you are connected, you will experience that joy of having unprecedented freedom on the web.

The Remote Authentication Dial-In User Service (RADIUS) protocol is used to provide centralized administration of authentication, authorization, and accounting (AAA) and an industry-standard security infrastructure. RADIUS is defined in RFCs 2138 and 2139 in the IETF RFC Database. RADIUS enables administrators to manage a set of authorization policies, accumulate accounting information, and access an account database from a central location.


IP / DNS leak test – PureVPN’s security mechanisms are based on the AES 256 bit encryption. This is the modern industry-standard of encryption that every VPN worth buying uses. Together with this mode of encryption and PureVPN’s DNS protection features, the possibility of IP or DNS leaks is all but completely ruled out. With security becoming a matter of utmost importance for users all over the world, PureVPN delivers just the right combination of speed and security for the users’ peace of mind.

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.


To send on a LAN or WAN link, the IP datagram is finally encapsulated with a header and trailer for the data-link layer technology of the outgoing physical interface. For example, when an IP datagram is sent on an Ethernet interface, the IP datagram is encapsulated with an Ethernet header and trailer. When an IP datagram is sent over a point-to-point WAN link such as an analog phone line or ISDN, the IP datagram is encapsulated with a PPP header and trailer.
Even the most expensive VPN plans are very affordable but you will likely have a budget in mind. 12-month plans typically offer the best value and you can reduce the risk of buyer’s remorse by choosing a VPN with a long refund period, preferably 30 days and with no questions asked. These guarantees are much more common than traditional free trials but are essentially the same thing.
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.
Jurisdiction – PureVPN has a fairly strong jurisdictional advantage. Hong-Kong is far from the watchful eyes of European governments and the 14 Eyes alliance. The state of the Internet in Hong Kong is one of the freest in the world. The government in Hong-Kong does not sweep online content under the rug of censorship. However, acts like distribution of child pornography are criminalized (as they should) by law and fall under the cloak of censorship. So, the jurisdiction of PureVPN should be a reason enough to compel privacy-conscious users to get this VPN.
Perfect Privacy holds the top spot as the best VPN for advanced online anonymity. While it may be overkill for basic users, this is a powerful VPN with advanced online anonymity features you will not find anywhere else. It is a well-regarded service that has earned high praise from the tech community for exposing vulnerabilities and flaws other VPN providers.

If you’re not looking to take advantage of its Channel Bonding functionality, users still benefit from a few tools designed to ensure users have a stable connection at all times. This includes its error correction algorithm that reduces packet loss and its automated, seamless network switching that acts as a failsafe should users step out of WiFi range or their primary connection fails.
When instructed, a demand-dial interface that is configured for auto-static updates sends a request across an active connection to request all of the routes of the router on the other side of the connection. In response to the request, all of the routes of the requested router are automatically entered as static routes in the routing table of the requesting router. The static routes are persistent: They are kept in the routing table even if the interface becomes disconnected or the router is restarted. An auto-static update is a one-time, one-way exchange of routing information.
As we already discussed in our guide of high-speed VPNs, VPN vendors use all essential privacy and security protocols to give everyone a safe-house access. However, it is subject to the protocol you use. As mentioned earlier, you need to select a right fast secure VPN protocol depending on your need. Use SSTP and OpenVPN protocols always if you are using torrent or bypassing firewalls like GFW, and NSA protocol. However, if only streaming is your concern, then switch to PPTP and L2TP protocols and get blazing fast VPN speed, with a little compromise on security. PPTP and L2TP are not unsafe, but they have low-security standards layers, that on the other hand, give you top speed for streaming.
TunnelBear is the undisputed best free VPN service available today. It's a serious VPN that's serious about customer satisfaction, privacy and security. So the upside is that you're getting a VPN that works, and can be trusted not to hold loads of data on you and sell you out at the earliest opportunity! The downside is that the free tier of TunnelBear only gets you 500MB bandwidth each month. That means for many people having it always-on will leave you caught short well before the end of the month, and absolutely rules out using it to stream endless episodes of Rick and Morty on Netflix. The free VPN tear at TunnelBear is certainly designed as a gateway to the paid tier which offers unlimited data but will cost you real money. If you're going to pay for a VPN we'd suggest getting a premium one like Express, but if you're only interested in a free option then TunnelBear is the one for you unless you need loads of bandwidth.
Cost: There's a 3 day free trial you can grab but you'll still need to enter your credit card. Otherwise, you can pay for VyprVPN every month for $9.95/month (or buy a year at once to bring that down to $5/month). Additional, there's a Premium plan for $12.95/month (or $6.67/month when billed annually) that lets you use your account on up to five devices at once, plus it supports Chameleon.
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.
It’s also fast with impressive 830+ server locations, which makes it an excellent choice for P2P file-sharing, online gaming, and HD streaming. There are no annoying bandwidth caps here, and you can connect to Netflix US, BBC iPlayer, or France’s Canal+ if you wish – there’s a server for every need. The double encryption will understandably slow things down.
Is using the web safely one of your concerns? Maybe you know someone who has been hacked or you’ve experienced it yourself. Have you ever wanted to purchase something or book travel but found it to be more expensive when you revisited it? Do you ever want to download a file but are unsure about your internet security? Or perhaps you’ve wanted to speak to family and friends but feel uncomfortable about how private your connection is. If one or more of these statements are concerns of yours, there is a solution — use a VPN, a way to disguise your IP address and add extra encryption to your data.
Even the most expensive VPN plans are very affordable but you will likely have a budget in mind. 12-month plans typically offer the best value and you can reduce the risk of buyer’s remorse by choosing a VPN with a long refund period, preferably 30 days and with no questions asked. These guarantees are much more common than traditional free trials but are essentially the same thing.

Android Pie, the 9th revision of the most popular mobile operating system on earth, is now available on Google’s Pixel phones starting Monday. Goole initially announced Android P, the previous name of Android Pie, in March, then at Google I/O conference in May they demoed some really cool features of the next version of Android. People who signed up for the Android Beta program, which lets you try out pre-released versions of the software, will receive the update by the “end of this fall,” if they have devices from Sony Mobile, Xiaomi, HMD Global, Oppo, Vivo, OnePlus and Essential.

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.

Computer and software providers work hard to make sure that the devices you buy are safe right out of the box. But they don't provide everything you'll need. Antivirus software, for example, consistently outperforms the built-in protections. In the same vein, VPN software lets you use the web and Wi-Fi with confidence that your information will remain secure. It's critically important and often overlooked.
Business VPN by KeepSolid is an affordable VPN service that supports remote access VPN  and offers premium VPN servers dedicated to your business. Built for SMBs, remote officers, on-the-go employees, and PR & Advertising companies, this platform touts an administrative portal for efficient team management alongside military-grade, 256-bit encryption to safeguard both corporate data and customer information.
And they manage to do all of this without sacrificing performance, offering one of the fastest download speeds (83 Mbps out of 100 Mbps) and the best 24/7 customer support in the industry. The only downside? It’s a little on the pricey side, with monthly plans starting between $6.67 and $12.95/mo. But it’s a small price to pay for excellent performance in almost every category.

Our runner-up is Hotspot Shield, which offers 500MB free per day, amounting to roughly 15GB per month. Like Windscribe, it didn't slow down our connections much. But Hotspot Shield admits that it partners with advertising networks and collects some user data. It also shows ads in the Android app, although the company says it no longer injects ads into websites displayed in a desktop web browser.
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.
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

TorGuard offers applications for every major platform, including Windows, macOS, and Android. And unlike our top pick, it also supports OpenVPN on ChromeOS. (Though TorGuard does offer an iOS app, it doesn’t natively support the OpenVPN protocol that allows for the easiest and most reliable secure connections.) Using these apps, you can manually select a server, click Connect, and not worry about the rest. But otherwise, the applications aren’t as refined or easy to use as IVPN’s. New users are likely to find themselves out of their depth when modifying anything but the most basic functions, such as auto-connecting at launch or minimizing the app.
Another approach is to offer purpose-specific servers. NordVPN, for example, has a high-speed server earmarked for video streaming. The company's collection of these special servers is a great way to offer customers a better experience, one tailored to their needs. It even offers Tor-over-VPN servers, for another layer of privacy. CyberGhost and PureVPN also place an emphasis on streaming, offering modes designed to connect you to your favorite content.

Compatibility – ExpressVPN is compatible with a wide range of devices and operating system. This includes Windows, OS X, Linux, and Chrome OS. In mobile phones and tablets, it is compatible with Android, iOS, Amazon Kindle Fire. It is also compatible with gaming and streaming consoles such as Amazon Fire TV, Chromecast, Apple TV, PlayStation 4, PlayStation 3, Xbox, Xbox One, and Roku. In short, I don’t think there is any other VPN provider that has such a wide cross-compatibility with different platforms.
Because a TCP connection is not used, L2TP uses message sequencing to ensure delivery of L2TP messages. Within the L2TP control message, the Next-Received field (similar to the TCP Acknowledgment field) and the Next-Sent field (similar to the TCP Sequence Number field) are used to maintain the sequence of control messages. Out-of-sequence packets are dropped. The Next-Sent and Next-Received fields can also be used for sequenced delivery and flow control for tunneled data.
Of course that brings up another problem. Since there are so many services to choose from, how can you tell which ones are worth using? PCWorld has taken care of much of the legwork with its Best VPN services roundup. [Spoiler alert: It found Mullvad to be a great all-around VPN for its above-and-beyond commitment to user privacy, and NordVPN to be the current choice for watching U.S. Netflix from abroad.]
Challenge Handshake Authentication Protocol (CHAP) is an encrypted authentication mechanism that prevents transmission of the actual password on the connection. The NAS sends a challenge, which consists of a session ID and an arbitrary challenge string, to the remote client. The remote client must use the MD5 one-way hashing algorithm to return the user name and a hash of the challenge, session ID, and the client’s password. The user name is sent as plain text.

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.
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 >]
When choosing your VPN, do your research and mind the legal aspects. Countries like Germany, France or Japan are cracking down on copyright infringement, while the members of the 14 Eyes treaty have draconian data retention laws and extensive surveillance. So, if you’re looking to maximize your privacy, you might want to avoid connecting to servers in those countries.
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 cause of this performance improvement was not immediately discernible. Experts I have spoken to have suggested the test cheating or data compression mentioned above. It was also suggested that, perhaps, some VPN companies had access to higher bandwidth connections in their networks. Another possibility was that our DSL line was artificially capped and that the VPN allowed our data to bypass that restriction.


OpenVPN: OpenVPN is very secure, open-source and widely used. Most VPN services support it, but except for Chrome OS and Linux, few operating systems do. This protocol can be used in either TCP (web) or UDP (streaming) mode; the latter is sloppier but faster. You'll need either the VPN service's client software or one of the many free alternatives. Either way, you'll still need to pay for the VPN service.
Jurisdiction – Panama is known as a tax haven, but its heavenliness extends to the domain of Internet privacy as well. Panama has one of the most state-of-the-art e-commerce and Internet banking infrastructure in the world. Since these are institutions that rely on strong security to be successful, Panama is subject to secrecy and privacy laws that favor the people. NordVPN’s main USP lies in the fact that it is based in Panama and thus can guarantee the perfect privacy of online activities and the identities of its users.
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.

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.
In short, latency is a time between a request sends and the response receives; it’s often called ping time. Factor that affects latency includes; the distance your request travels. It’s important when playing video games with a VPN, lower the latency, more responsive the experience will, with less lag. Download and upload speeds measure the amount of data is moved over your internet connection. These are measured in Megabits per second (Mbps); it shows the data runs through a network in a given frame of time. The more, the better. Simple.
Security is second to none with NordVPN. Its kills switch feature always monitors traffic between devices and the VPN servers. If for some reason, the data stream breaks, the kill switch will automatically terminate the connection, ensuring that your traffic is protected from prying eyes. Also, a DNS leak feature changes your DNS to point to the VPN server, ensuring that hackers cannot steal data from your default DNS.
The main reason to use a VPN is security - in theory, the data that travels across your VPN should be impossible for anybody else to intercept, so it can protect your online banking or confidential business communications - but there are other benefits too. VPNs can make it much harder for advertising to track you online, and they can overcome geography-specific blocks that prevent you from accessing some country-specific services such as online video.
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.)

To be sent on a local area network (LAN) or WAN link, the IP datagram is finally encapsulated with a header and trailer for the data-link layer technology of the outgoing physical interface. For example, when IP datagrams are sent on an Ethernet interface, the IP datagram is encapsulated with an Ethernet header and trailer. When IP datagrams are sent over a point-to-point WAN link, such as an analog phone line or ISDN, the IP datagram is encapsulated with a PPP header and trailer.
If you’re unsure about whether you should get a VPN, check out our post that explains what a VPN is and when one makes sense as a privacy and security tool. But most people leave their privacy and security vulnerable in ways that can be addressed with methods other than signing up for a VPN—methods that are potentially more effective. If you have a drafty house with paper-thin walls and halogen light bulbs, you’d get far more value out of every dollar by sealing up cracks, insulating, and switching to LEDs than you would by putting solar panels on your roof. Similarly, before you rush to sign up for a VPN subscription, you should consider these other ways to up your privacy game.
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.

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.
