There was a time when using a VPN required users to know about the built-in VPN client for Windows or universal open-source solutions such as OpenVPN. Nowadays, however, nearly every VPN provider has its own one-click client that gets you up and running in seconds. There are usually mobile apps as well to keep your Android or iOS device secure over public Wi-Fi.
A virtual private network (VPN) extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running across a VPN may therefore benefit from the functionality, security, and management of the private network.[1]
A remote-access VPN uses public infrastructure like the internet to provide remote users secure access to their network. This is particularly important for organizations and their corporate networks. It's crucial when employees connect to a public hotspot and use the internet for sending work-related emails. A VPN client, on the user's computer or mobile device connects to a VPN gateway on the company's network. This gateway will typically require the device to authenticate its identity. It will then create a network link back to the device that allows it to reach internal network resources such as file servers, printers and intranets, as if it were on the same local network.
The VPN services market has exploded in the past few years, and a small competition has turned into an all-out melee. Many providers are capitalizing on the general population's growing concerns about surveillance and cybercrime, which means it's getting hard to tell when a company is actually providing a secure service and when it's throwing out a lot of fancy words while selling snake oil. In fact, since VPN services have become so popular in the wake of Congress killing ISP privacy rules, there have even been fake VPNs popping up, so be careful. It's important to keep a few things in mind when evaluating which VPN service is right for you: reputation, performance, type of encryption used, transparency, ease of use, support, and extra features. Don't just focus on price or speed, though those are important factors.
To verify that each service effectively hid our true IP address, we looked at a geolocation tool, DNS leaks, and IPv6 leaks. When connected to each service's UK servers, we noted if we could watch videos on BBC iPlayer, and using US servers we noted if we could stream Netflix. We also visited the sites of Target, Yelp, Cloudflare, and Akamai to check if our VPN IP addresses prevented us from accessing common sites that sometimes blacklist suspicious IP addresses.
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:
Individuals that access the internet from a computer, tablet or smartphone will benefit from using a VPN. A VPN service will always boost your security by encrypting and anonymizing all of your online activity. Therefore, both private and business users can benefit from using a VPN. Communications that happen between the VPN server and your device are encrypted, so a hacker or website spying on you wouldn't know which web pages you access. They also won't be able to see private information like passwords, usernames and bank or shopping details and so on. Anyone that wants to protect their privacy and security online should use a VPN.
Servers – IPVanish has a moderately-sized server network of 1,000 servers. Geographically, it covers 60 regions around the world. Although this is relatively small than the VPNs provided above, this is still better than many other VPN providers. IPVanish provides a lot of control to the user when it comes to selecting a server. You can filter VPNs by country, city, and latency. The best thing about it is that IPVanish is remarkably fast in establishing a connection with any server location of your choice.
The service supports Windows, Mac, Android and iOS devices, but manual connection through Linux, BlackBerry, Boxee Box, HP WebOS or DD-WRT is also possible. It likewise allows users to use up to five devices using the account. PureVPN’s proprietary gigabit network ensures uptime and extremely fast speeds. It offers unlimited bandwidth, which is ideal for users who like video streaming or playing online games.
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.
L2TP uses UDP messages over IP networks for both tunnel maintenance and tunneled data. The payloads of encapsulated PPP frames can be encrypted or compressed (or both); however, L2TP clients do not negotiate the use of MPPE for L2TP connections. Encryption for L2TP connections is provided by IPSec Encapsulating Security Payload (ESP) in transport mode.
Windscribe, one of the best free VPNs out there, is definitely a user favorite. While its adblocker and firewall can be a little aggressive, Windscribe’s generous data allowance and commitment to privacy easily make it one of our top free picks. Not only does it allow 10 GB of data month, you get an extra 5 GB for tweeting about the service, and an extra 1 GB every time you refer a friend.
Trust and transparency issues are the foremost concerns in choosing a great VPN, and if a service doesn’t have enough locations to be useful to you, all the security features won’t make a difference. But after those concerns have been satisfied, we recommend that most people use connections based on the OpenVPN protocol, because of security flaws and disadvantages in the PPTP and L2TP/IPsec protocols. (Experienced users may consider IKEv2, but because it has its own debated pros and cons, we ruled it out.) Though AES 128-bit encryption is fine for most purposes, we prefer services that default to the more-secure 256-bit encryption and still offer good performance.

Various countries around the world restrict access to one type of online content or another. Social networks, games, chat apps – even Google itself is not beyond the reach of censorship. In addition, many academic institutions and workplaces enable firewalls to limit access to websites for various reasons. These range from seeking to increase productivity to restricting inappropriate content.
Here's the problem with the internet: It's inherently insecure. When the internet was first designed, the priority was to be able to send packets (chunks of data) as reliably as possible. Networking across the country and the world was relatively new, and nodes often went down. Most of the internet's core protocols (methods of communicating) were designed to route around failure, rather than secure data.
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.)
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.

TorGuard’s signup and payment process is also fine but not stellar. Compared with that of IVPN, the checkout process is clunky, and using a credit or debit card requires entering more personal information than with our top pick. The easiest option for anonymous payments is a prepaid debit card bought locally. Otherwise, like most providers, TorGuard accepts a variety of cryptocurrencies, PayPal, and foreign payments through Paymentwall. That last service also allows you to submit payment through gift cards from other major retailers. We don’t think this method is worth the hassle for most people, but if you have some money on a fast-food gift card you don’t want, turning it into a VPN service is a nice option.
Windscribe  offers unlimited device connections. Yes you heard that right! The reason is that unlike the others above on this list, it doesn't offer unlimited data. So you're limited by bandwidth and data, not by devices. You get 10GB every month, and there's a free plan also but that only allows one device. There are apps for Windows, Mac and iOS but not Android, and the service also offers browser add-ons with useful features such as ad-blocking. Short range performance (to US sites) is good, but we noticed lag with transatlantic connections. However, if you’re looking to protect the data from a whole bunch of devices - an office, perhaps, or just a smart home - the support for unlimited connections is a real stand-out feature.
Final Verdict – PIA is a reliable VPN service that only uses physical servers in its VPN network. It does not make any exaggerated claims of its qualities and clearly describes its policies and features. Moreover, the low price is another positive attribute of the VPN. In a nutshell, PIA is a VPN you can trust, though it is not an ideal VPN for torrenting.
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.
Tunneling is a network technology that enables the encapsulation of one type of protocol packet within the datagram of a different protocol. For example, Windows VPN connections can use Point-to-Point Tunneling Protocol (PPTP) packets to encapsulate and send private network traffic, such as TCP/IP traffic over a public network such as the Internet.
Internet Protocol Security (IPsec) was initially developed by the Internet Engineering Task Force (IETF) for IPv6, which was required in all standards-compliant implementations of IPv6 before RFC 6434 made it only a recommendation.[7] This standards-based security protocol is also widely used with IPv4 and the Layer 2 Tunneling Protocol. Its design meets most security goals: authentication, integrity, and confidentiality. IPsec uses encryption, encapsulating an IP packet inside an IPsec packet. De-encapsulation happens at the end of the tunnel, where the original IP packet is decrypted and forwarded to its intended destination.

Not all mobile VPN apps are created equal. In fact, most VPN providers offer different services (and sometimes, different servers) for their mobile offerings than they do for their desktop counterparts. We're pleased to see that NordVPN and Private Internet Access provide the same excellent selection of servers regardless of platform. These apps received an Editors' Choice nod both for desktop VPN apps and Android VPN apps.


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.
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.
It usually relies on either Internet Protocol Security (IPsec) or Secure Sockets Layer (SSL) to secure the connection. However, SSL VPNs can also be used to supply secure access to a single application, rather than an entire internal network. Some VPNs also provide Layer 2 access to the target network; these will require a tunneling protocol like PPTP (Point-to-Point Tunneling Protocol) or L2TP (Layer 2 Tunneling Protocol) running across the base IPsec connection.
Business security and strength. Businesses aren’t immune to hacking and someone getting into your system to access consumer records could be a catastrophe and lead to significant losses for everyone involved. Some businesses operate on multiple networks, potentially leaving entryways for thieves. Remote businesses are becoming the norm and employees could become targets for passage into large and secure systems. Using a VPN helps prevent such situations from happening, regardless of whether or not you’re on a public network. Your network will be encrypted, and your business will remain secure.
To verify that each service effectively hid our true IP address, we looked at a geolocation tool, DNS leaks, and IPv6 leaks. When connected to each service's UK servers, we noted if we could watch videos on BBC iPlayer, and using US servers we noted if we could stream Netflix. We also visited the sites of Target, Yelp, Cloudflare, and Akamai to check if our VPN IP addresses prevented us from accessing common sites that sometimes blacklist suspicious IP addresses.
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.
NordVPN, for example, has well over 4,800 servers across the globe. If you live in the US, you're likely to find a nicely uncrowded server close by. The ubiquity of its servers also means you're likely to find a server nearby no matter where you travel. Private Internet Access and TorGuard are notable for being the only VPNs we've yet reviewed that have more than 3,000 servers.
Most VPNs won’t keep any logs of user activity. Not only is this of benefit to their customers (and a great selling point) it’s also of huge benefit to them (as detailed logging can quickly consume disk after disk worth of resources). Many of the largest VPN providers will tell you as much: not only do they have no interest in keeping logs, but given the sheer size of their operation they can’t even begin to set aside the disk space to do so.
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.
Not all mobile VPN apps are created equal. In fact, most VPN providers offer different services (and sometimes, different servers) for their mobile offerings than they do for their desktop counterparts. We're pleased to see that NordVPN and Private Internet Access provide the same excellent selection of servers regardless of platform. These apps received an Editors' Choice nod both for desktop VPN apps and Android VPN apps.
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.
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. 
So our advice is to not use a free VPN unless it really is for occasional, very casual use. For the odd IP-hopping use case, they can work. But if you're planning on using the VPN a lot and for streaming video etc we'd highly recommend going for one of the overall best VPN services - they're not free but they're also pretty cheap in the grand scheme of things.
A proxy server is another way to conceal your real location. By transferring data through a proxy server the data appears to be going to that server, not you - so for example if you’re in the US and the proxy is in Switzerland, the website or service will think it’s talking to a machine in Switzerland. The main difference is that VPNs protect all your traffic while proxies tend to be limited to specific types of data, such as peer to peer networking or web browsing. 
Some VPN services will limit the total amount of data you can send and receive, either in one connection session or over the period of a month. Other VPN services will limit the speed of the data, effectively sharing less of their pipe with you than might be optimal. That could slow your browsing experience to a crawl or completely prevent you from watching streaming video.
Pricing is quite flexible, with a three-day plan available for just $2. But for those who want to avail of the complete service and support, A basic plan of $5 per month, a solid plan of $10 a month, and dedicated plan of $25 per month are also available. These packages offer users access to Proxy.sh servers in different countries and unlimited bandwidth. Custom plans can be arranged, all one has to do is contact support.
The free tier gives you the Windows, Mac, iOS, Android and Amazon Fire TV/Firestick client software (and the beta Linux software, should you wish to try it); the Windflix feature to (try to) watch U.S. or U.K. Netflix streams; the Chrome, Firefox and Opera Windscribe browser extensions to block ads and trackers; a separate firewall built in to the Windows and macOS clients; and the ability to connect to VPN servers in 11 countries, mostly in Europe and North America.
Windscribe, one of the best free VPNs out there, is definitely a user favorite. While its adblocker and firewall can be a little aggressive, Windscribe’s generous data allowance and commitment to privacy easily make it one of our top free picks. Not only does it allow 10 GB of data month, you get an extra 5 GB for tweeting about the service, and an extra 1 GB every time you refer a friend.
Although the diminishing online privacy of users has been a long-running theme in the digital world, the recent Facebook-Cambridge Analytica scandal was the first exposure of our fragile privacy on a global level. It is in these circumstances that the search for best VPN services has become our answer to the continually shrinking privacy and security of the average netizen.
We’ll get to the implications of a VPN’s location in a moment, but first, let’s get back to our secure tunnel example. Once you’re connected to the VPN and are “inside the tunnel,” it becomes very difficult for anyone else to spy on your web-browsing activity. The only people who will know what you’re up to are you, the VPN provider (usually an HTTPS connection can mitigate this), and the website you’re visiting.
VPNs also cloak your computer's actual IP address, hiding it behind the IP address of the VPN server you're connected to. IP addresses are distributed based on location, so you can estimate someone's location simply by looking at their IP address. And while IP addresses may change, it's possible to track someone across the internet by watching where the same IP address appears. Using a VPN makes it harder for advertisers (or spies, or hackers) to track you online.
