A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryption. A VPN available from the public Internet can provide some of the benefits of a wide area network (WAN). From a user perspective, the resources available within the private network can be accessed remotely.
If you require a high level of trust on the authentication process as well as the encryption, you might consider using digital certificates instead of the standard preshared secret key that most VPNs default to. Digital certificates guarantee that the person trying to connect is who he or she says he or she is. A separate digital certificate for each end connection can be expensive; however, some VPN vendors offer authentication services that provide a bulk discount on certificates.

[...] VPNs using dedicated circuits, such as Frame Relay [...] are sometimes called trusted VPNs, because customers trust that the network facilities operated by the service providers will not be compromised.
Private Internet Access, or PIA, is one of the most visible, privacy-focused VPNs available. Because of its reputation and advocacy concerning online privacy and security, it has also been a Wirecutter staff pick. But whether you prioritize speed and performance or trust and transparency, our top pick is a better bet. If you find PIA attractive because of its low price, note that spending just a little more on TorGuard will buy you much better performance.
If you download and upload content, movies, and games on a daily basis, PureVPN is a choice with notably fast downloading and uploading speeds. Compared to other VPNs that get the same speed (like Astrill), it's considerably more affordable. PureVPN has more than 500 servers spanning across 140 countries and impeccable access in China — and may be the only option available in some places. Pure VPN is also extremely accessible when it comes to devices: It's compatible with Windows, Mac, iOS, Android, Chrome, and Firefox, as well as apps for media streaming devices like Android TV, Amazon Fire TV Stick, and Kodi. So, if nothing else, it's one of the most versatile of the bunch. Though Mashable dubbed it one of the best due to its speed and how many things it can do, Reddit users insist that it is not a trustworthy choice. Multiple Redditors claim that PureVPN lies to users about not logging their information or search history when they really do. Some also believe that PureVPN uses spammers and claim that a lot of positive feedback about PureVPN on Reddit are from fake accounts. Reddit user cloudhat writes:
Since NordVPN is a leader in the VPN industry, the Trial gives a serious blow to all its customers. Allegations indicate that Tesonet – a data mining firm – is behind the creation of NordVPN. In light of this, the provider understands that they have to gain the trust of their customers back. Therefore, just yesterday they announced that they would be hiring one of the largest professional service firms.
Whereas most providers say they log nothing, that’s not always the case. Some record very little data like the day you subscribed, the amount of data you’ve consumed, and delete those logs when you end the session. Other providers log your IP address, the servers you used, and store those logs. If they’re based in the US, UK or any other country with data retention laws, they can be compelled to hand over that data to law enforcement.
Even though Tor is free, we don’t think it’s the best option for most people. If you aren’t familiar with Tor, this handy interactive graphic shows how it protects an Internet connection, and this series goes into more detail about how Tor works. Runa Sandvik, a former researcher with The Tor Project who is now part of the information security team at The New York Times (parent company of Wirecutter), described it as “a tool that allows users to remain anonymous and uncensored.” When we asked expert Alec Muffett about whether he personally used a VPN, he told us he actually spent most of his work time using Tor. But Tor has a reputation for slow connections, can be blocked by some websites, and isn’t suitable for some peer-to-peer applications like BitTorrent.
Norton WiFi Privacy performed very well in our latest round of speed tests. In the UK, we got FTP and HTTP download speeds of around 9.5MB/s (76Mb/s). Using endpoints in the Netherlands, that HTTP speed went up to 10.1MB/s (81Mbit/s). U.S. speeds were also very good, exceeding our non-VPN reference download at 5.8MB/s (46.4Mbit/s) for FTP and 4.8MB/s (38.4Mbit/s) for HTTP downloads.
That depends. VPN use is legal in most countries, but, according to VPN provider CyberGhost, VPN use is illegal in the United Arab Emirates, Turkey, China, Iran, North Korea, Saudi Arabia, and Russia. Vladimir Putin has recently banned VPN use in Russia. Also, be aware that the so-called proxy server alternative to VPNs is also illegal in many countries, which consider any form of IP spoofing to be illegal, not just those services labeled as VPN.
Virtual LAN (VLAN) is a Layer 2 technique that allow for the coexistence of multiple local area network (LAN) broadcast domains, interconnected via trunks using the IEEE 802.1Q trunking protocol. Other trunking protocols have been used but have become obsolete, including Inter-Switch Link (ISL), IEEE 802.10 (originally a security protocol but a subset was introduced for trunking), and ATM LAN Emulation (LANE).
VPN stands for “virtual private network,” – as its name indicates, it’s used for connecting to private networks over public networks, such as the Internet. In a common VPN use case, a business may have a private network with file shares, networked printers, and other important things on it. Some of the business’s employees may travel and frequently need to access these resources from the road. However, the business doesn’t want to expose their important resources to the public Internet. Instead, the business can set up a VPN server and employees on the road can connect to the company’s VPN. Once an employee is connected, their computer appears to be part of the business’s private network – they can access file shares and other network resources as if they were actually on the physical network.
VPN security boils down to two main topics: encryption level and protocol. The VPN protocol determines how the connection will happen, what encryption the connection will use and other miscellaneous information for establishing it. We normally stick to OpenVPN, but you can learn about the differences between protocols in our VPN protocol breakdown.
With hundreds of VPN services and clients available, it can be difficult to decide which one to use. We've extensively tested several popular VPN services that met three requirements: They had both desktop and mobile client software (with one exception), they had VPN servers in many countries, and they offered unlimited data use, at least in their paid versions.
When it comes to security, the company definitely lives up to the good renown it has built over the years. PureVPN utilizes AES 256-bit encryption and the latest security protocols – IKEv2, OpenVPN, PPTP, SSTP, L2TP/IPSec among others. Split Tunneling and Virtual Router are arguably the best technologies that it can offer. The main reason for this is that as Virtual Router provides high-end router protection, the Split Tunneling service allows for encrypting only the important bits of data. In this way you are being protected, while slow-downs in connectivity, due to the result of encryption, are kept to a bare minimum.
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.
