A virtual private network supplies network connectivity over a potentially long physical distance. In this respect, a VPN is a form of a Wide Area Network. VPNs support file sharing, video conferencing and similar network services.
A VPN can work over both public networks like the Internet and private business networks. Using a method called tunneling, a VPN runs over the same hardware infrastructure as existing Internet or intranet links. VPN technologies include various security mechanisms to protect these virtual connections.
Virtual private networks generally don't provide any new functionality that isn't already offered through alternative mechanisms, but a VPN implements those services more efficiently and cheaply in most cases. Specifically, a VPN supports at least three different modes of use:
Internet remote access client connections
LAN-to-LAN inter-networking
Controlled access within an intranet
Internet VPNs for Remote Access
In recent years, many organizations have increased the mobility of their workers by allowing more employees to telecommute. Employees also continue to travel and face a growing need to stay connected to their company networks.A VPN supports remote, protected access to the corporate home offices over the Internet. An Internet VPN solution uses a client/server design and works as follows:
A remote host (client) intending to log into the company network first connects to any public Internet connection.
Next, the client initiates a VPN connection to the company VPN server. This connection is made using a VPN application installed on the remote computer.
After the connection has been established, the remote client can communicate with the internal company systems over the Internet just as if it were inside the local network.
Before VPNs, remote workers accessed company networks over private leased lines or through dialup remote access servers. While VPN clients and servers careful require installation of hardware and software, an Internet VPN is a superior solution in many situations.
VPNs for Personal Online Security
Several vendors offer subscription services to virtual private networks. When you subscribe, you'll get access to their VPN service, which you can use on your laptop, PC or smartphone. The VPN's connection is encrypted, meaning people on the same Wi-Fi network (like at a coffee shop) cannot "sniff" your traffic and intercept information like your social media accounts or banking information.VPNs for Internetworking
Besides using virtual private networks for remote access, a VPN can also bridge two networks together. In this mode of operation, an entire remote network (rather than just a single remote client) can join to a different company network to form an extended intranet. This solution uses a VPN server-to-server connection.Intranet Local Network VPNs
Internal networks may also use VPN technology to implement controlled access to individual subnets within a private network. In this mode of operation, VPN clients connect to a VPN server that acts as the network gateway.This type of VPN use does not involve an Internet Service Provider or public network cabling. However, it allows the security benefits of a VPN to be deployed inside an organization. This approach has become especially popular as a way for businesses to protect their Wi-Fi local networks.
The best VPN service 2019
1. ExpressVPN
ExpressVPN has long been recognized as one of the world's top VPN providers, with fast speeds and solid customer support.

Express VPN Activation Code - Serial Keys |
With 148 locations in 94 countries and available through plenty of clients, it’s the best services out there. Regardless of your platform, you will find a native client, as ExpressVPN offers clients for Mac, Windows, Linux, but also iOS and Android, and even BlackBerry (albeit limited to a handful of models).ExpressVPN also offers routers with custom firmware and VPN browser extensions, making it an all-around great service. A wide variety of simple and useful web-based tutorials will make sure you're up and running in no time. This includes P2P support, a kill switch, and generally good performance.
2. NordVPN
Security is its middle name
One would expect such a powerful solution to be located in one of the world’s largest tech hubs, but NordVPN is located in Central America. Its key advantages are a large pool of servers (5,000+), and more than 60 locations around the globe. It can support up to six devices at the same time, and the data gets a 2048-bit encryption. Features like DNS leak protection, killswitch, dedicated IP address and being able to pay with cryptocurrency are also very worth mentioning. Even when it came to the most important part – performance – NordVPN stood strong. Its speeds for short connections were commendable, long-term ones – delicious. The downside is the privacy policy – its stance on session logging is somewhat unclear. IT does state a ‘no logs policy’, though.
3. IPVanish
Great for P2P and torrenting
For IPVanish, its key selling point is the quality of service.
The company claims to offer “the world’s fastest VPN”, with more than 40,000 shared IPs, almost a thousand VPN servers spread across 60 countries, unlimited P2P traffic, five connections and lo logs. If the price is your main concern you might want to look elsewhere, but in other cases, IPVanish is a serious contender with fast speeds, plenty locations to choose from and a well-built client (even though its latest Windows client could use a bit more work – it suffers from the odd network issue).
4. Hotspot Shield
Awesome solution for online browsing
Hotspot Shield Elite is another of the market's top offerings, coming with all the necessities at a competitive price and the ability to purchase a lifetime license. Private browsing, “access all content”, and up to five simultaneous devices – those are the aces up Hotspot Shield’s sleeves. Performance-wise it lacks for nothing, there’s an ever so slight increase in latency, with both upload and download speeds a bit faster after being connected. What we’d like to see is more freedom for configurations, and more locations. However, with such high speeds and competitive prices, there’s very little room to feel unsatisfied. At the end of the day, there is a seven-day trial for everyone to see for themselves.
5. CyberGhost
Rich clients and awesome configurability

With multiple clients, rich with different features, it’s no wonder this VPN service handles more than 10 million users. CyberGhost 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. One feature in particular, which stands out, is the option of kicking off the VPN when specific apps are launched.Torrent users will be happy to hear that this service supports them on most of its servers. Performance-wise it is solid. It offers a free plan that comes with a few caveats, including just one device at a time, being a bit slower than the commercial version, and ads. Data usage is unlimited, and for those looking to buy, they have a 30-day money-back guarantee.
6. TunnelBear
Easy to use VPN
Whenever someone mentions TunnelBear, ease of use is the first thing that comes to mind. This Canada-based VPN offers extremely good user experience, but also plenty of clients to choose from on both desktop and mobile platforms. Its hassle-free approach is clearly visible from the company's website – the language is as simple as it can be. Experts, on the other hand, might not enjoy not being able to get access to all the nuts and bolts of the clients. So if you're a beginner – this one is for you.TunnelBear comes with servers in more than 20 countries and offers up to five connections at the same time, which is pretty good, all things considered. It has strong privacy measures and clear policies. It also performed really well in our tests, even though long-distance connections seem to drop in speed.
7. Windscribe
A VPN which gives you unlimited connections
This service offers four native clients – one for Windows, Mac, iOS, and Android. Be advised that the Android one is still new and could be a bit unstable, so proceed at your own risk. There are also solidly built browser add-ons. Windscribe's strongest selling point is that it offers unlimited connections with its commercial plans, so it can cover everything, regardless of how many machines you throw at it. With a clear-cut privacy policy and a simple, powerful Windows client, it’s easy to see why Windscribe made it to this list. Performance might disappoint you a bit as we can only describe it as average. Still, it offers a free plan with 10GB monthly data (albeit for one device only).
8. VyprVPN
A great choice for those looking for security
VyprVPN looks to stand out from the crowd with a useful unlimited data usage offering. The service is also based in Switzerland, meaning it can benefit from the country’s advanced privacy laws. There are more than 70 server locations around the world and comes with cool features like auto-connect or a killswitch. Clients are very intuitive, especially the Windows offering, and the service includes VyprDNS and the Chameleon protocol to provide extra security. There are no refunds, but there is a three-day trial. When it comes to subscribing, you can choose either a monthly or an annual plan, be it either Basic or Premium.
