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.
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.
Welcome to the CNET 2018 Directory of VPN providers. In this directory, we're taking a look at a few of the very best commercial VPN service providers on the Internet like CyberGhost, IPVanish, Buffered, Private Internet Access and others. Rather than looking at the wide range of free providers, which often have a lot of limits (and dubious loyalties), we are looking at those vendors who charge a few bucks a month, but put your interests first, rather than those of shadowy advertisers and sponsors. Our VPN rankings are based more than 20 factors including number of server locations, client software, dedicated and dynamic IP, bandwidth caps, security, logging, customer support and price. 

Speed should not be all you consider when shopping for a VPN. For one thing, your internet experience will almost certainly be faster without a VPN. For another, speeds depend so much on which server you use, where you are, what your network environment is like, and so on. You might find that the service that's lightning fast today is dog slow tomorrow.

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.


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.
SSTP, Secure Socket Tunneling Protocol is designed to work on Windows only. It is considered as a fast secure VPN protocol as it supports up to 256-bit encryption to route the traffic. SSTP uses SSL channels to pass all PPTP and L2TP protocol that makes the browsing journey secure and fast. It is also designed in a way to bypass intense geo-restriction and break the firewalls. The only demerit we see in SSTP fast VPN protocol is its limited support on OS and devices. Although, if you compare PPTP and L2TP parallel to SSTP, you will not experience a high-speed VPN connection, it is to understand that SSTP is more focused on delivery privacy coupled with adequate speed.
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.
Additionally, moves from the FCC to remove rules regarding net neutrality have raised questions about VPNs. Without net neutrality rules, it's possible that ISPs could charge companies extra for access to "fast lanes" that would deliver content faster. ISPs could also create cable TV-style packages where you pay for individual access to websites. A VPN might be able to restore net neutrality, somewhat, by tunneling past ISP restrictions. Unfortunately, we'll have to see how all this plays out before we can say for certain how much a VPN might help.
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.

Hotspot Shield is an awesome free VPN that has helped millions of people in their time of need. It was the most used VPN during the Turkey coup and the Arab Spring. Users get free access not only to the VPN but also a Chrome extension. The free service permits connections to the US only, but the extension permits connections to 14 countries (but not the US). The result is that Hotspot Shield users can unblock content in 15 countries for free! What’s more, Hotspot Shield’s free plan lets people have 500MB of download use per day. That is a massive usage allowance considering it is free.


In recent times, VPN services have made giant leaps in growing from niche online products hidden away in a dark corner of the internet to almost must-have services for anyone with an internet connected device. VPN is very much in the mainstream now and luckily that broadened appeal has done wonders for the usability of the services themselves - there are some brilliant options available in 2018.
Two networks can be connected over an intranet using a site-to-site VPN connection. This type of VPN connection might be necessary, for example, for two departments in separate locations, whose data is highly sensitive, to communicate with each other. For instance, the finance department might need to communicate with the human resources department to exchange payroll information.
Oh, heck no. A VPN can help make sure you're not snooped on when connecting between your computer and a website. But the website itself is quite capable of some serious privacy violations. For example, a VPN can't protect you against a website setting a tracking cookie that will tell other websites about you. A VPN can't protect you against a website recording information about products you're interested in. A VPN can't protect you against a website that sells your email address to list brokers. Yada, yada, yada.
Cost: To be billed every 7 days, you can subscribe to ZenVPN on a weekly basis for $2.95, which is equivalent to around $11.80/month. Another option is to just buy it a month at a time for $5.95/month. A third option is to buy a whole year at once (for $49.95) for what comes out to be $4.16/month. The unlimited option is more expensive, at $5.95/week, $9.95/month or $7.96/month if you pay $95.50 for the whole year.
VyprVPN is a powerful contender if you’re after performance and security. It boasts great speeds due to a staggering network of 700+ serves and more than 200K IP addresses. They own and manage their servers, which translates into reliable uptime, lag-free performance, top-notch support and great speeds. Add in unlimited bandwidth and P2P support, successful handling of Netflix and Steam geo blocks, and you can check all your VPN must-have features right off the bat.
The world wide web is a massive place that allows you to connect with people from all over the world. Unfortunately, there are people out there who use valuable technology to steal information and use it for their own profit. Fortunately, we can help with our free VPN service. Don’t remain vulnerable to any potential attacks from thieves. Our services are fast, reliable, and free to use.
ExpressVPN attempts to build trust in other ways, even without a public face. Court records from 2017 demonstrate that when Turkish authorities seized ExpressVPN servers in the country looking for information, they found nothing of value, as promised by ExpressVPN’s no-logging policy. ExpressVPN also highlights initiatives such as open-source leak-testing tools, developer content about how the company implements different technologies, and support for the efforts of OpenMedia and the EFF. The ExpressVPN representative even offered to arrange a confidential call between our writer and the owners of the company. However, without being able to discuss their identities or learn about other senior leadership, we believed that wouldn’t have been enough to change our recommendation, so we declined. In the end, trust is such a crucial part of deciding which VPN to use that we had to pass on ExpressVPN.
When we took at look at your five favorite VPN service providers, we noticed a few things. First, being the “best” is big business for VPN providers, and they’ll fight dirty to be one of them. Second, there are so many VPN providers that it’s difficult to choose a really good one. VPNs are not all created equally, and in this post, we’re going to look at what a VPN is, why you want one, and how to pick the best one for you. Let’s get started.

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.


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.
With  multiple clients, rich with different features, it’s no wonder this VPN service handles more than 10 million users. It covers Microsoft’s and Apple’s operating systems, but also iOS and Android. The interface is not the best out there and could definitely use some work, but these disadvantages are easily overshadowed by the awesome features this VPN offers.
Internet connection has changed the lives of many people. Today, they are more than 3.5 billion in the world to connect on this large public network. Some Internet users connect to the Internet for entertainment, information sharing, information, watching videos, etc., and others for purely business reasons. In both cases, Internet users should always use a VPN to secure their connection and surf more freely and anonymously on the Internet.
Two networks can be connected over an intranet using a site-to-site VPN connection. This type of VPN connection might be necessary, for example, for two departments in separate locations, whose data is highly sensitive, to communicate with each other. For instance, the finance department might need to communicate with the human resources department to exchange payroll information.

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.
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.
The main drawback with ZorroVPN is that they do not offer custom VPN applications. This means you will need to use third-party VPN apps, such as Viscosity or Tunnelblick, and that setup will be more complex. Some people, however, prefer open-source applications, but regardless, they are also working on creating their own app for Windows and Linux (still in beta).
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:
Here you should remember that before being sent and received over the Internet, any data needs to first be split into packets. To ensure each data packet stays secure, a VPN service wraps it in an outer packet, which is then encrypted through a process called encapsulation. This exterior packet keeps the data secure during the transfer, and it is the core element of the VPN tunnel. When the data arrives at the VPN server, the outer packet is removed to access the data within, which requires a decryption process.
We’ve shown you how to roll your own VPN using Hamachi, and even how to set up Privoxy to secure your web browsing once you have your personal VPN set up. Hamachi isn’t the only option: you can also download and configure OpenVPN (a free SSL VPN) on your own home server,, or if you have a router that supports it, enable OpenVPN on your home router so you can connect back to it when you’re abroad. Combined with Privoxy, you get the privacy and anonymity benefits of a VPN without spending a dime.
We have tested dozens of VPN providers in our quest to find the most reliable and fast secure VPNs. During our test, we found that a lot of VPN services falls short on the minimum speed benchmark requirements we have set. Hence we excluded them from our fastest VPN list. This doesn’t mean that those VPNs are not good, but we aim to rank the ones that give top-notch VPN speed on the grounds of many factors. Below are the top 5 fast VPN providers that secured the position in our list of high-speed VPNs to use in 2018.

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.

Let's start with the basic idea of internet communication. Suppose you're at your desk and you want to access a website like ZDNet. To do this, your computer initiates a request by sending some packets. If you're in an office, those packets often travel through switches and routers on your LAN before they are transferred to the public internet through a router.
IVPN goes further than the other leading candidates we considered by being transparent about who runs the service and is responsible for your privacy. The company lists its core team on its website, and its small team has an online presence on a variety of platforms. In contrast, only one employee at ExpressVPN has a public face: VP of marketing Harold Li gave us detailed answers to questions about policies and internal security, but couldn’t tell us much about who else worked there. (We discuss ExpressVPN in more detail in the Competition section—that company was almost our top pick but for this issue.)
Every service we tested accepts payment via credit card, PayPal, and Bitcoin. That’s plenty of options for most people, and you can always use a prepaid debit card if you don’t want your billing information tied to your VPN account. IVPN and OVPN are the only ones to accept cash payment through the mail, if you really don’t want to make a payment online. Private Internet Access and TorGuard accept gift cards from other companies—IVPN doesn’t, but that option isn’t worth the additional hassle for many people when other secure, private methods are available.
Tunneling protocols such as PPTP and L2TP are implemented at the data-link layer of the Open Systems Interconnection (OSI) reference model and provide data security by helping to create secure tunnels. In contrast, the IPSec protocol is implemented at the network layer and helps secure data at the packet level. IPSec provides two security protocols: Authentication Header (AH) and ESP.
Servers – IVPN offers 51 servers located in 23 countries. IVPN offers a multi-hop feature for in all of these servers, which basically scatters the traffic of users by moving it through different servers before finally reaching its true destination. This serves to enhance the security and helps protect the identity of the user. It is this feature that sets the VPN’s network apart from its competitors, something I found really good during IVPN review.

All that being said, we currently name TorGuard as the fastest VPN service. It doesn't take the top spot in all of our tests, but has remarkably low latency and had the best performance in the all-important download tests. Fittingly, it offers many add-ons such as dedicated IP addresses that, along with its speed, will appeal to the BitTorrent users it is designed to protect.
