We'll go into greater explanation about these three metrics and how we collect them below. But choosing which is most important is tricky. Mostly, it depends on how you're using your internet connection. We assume that most people reading are major consumers of content. Reading the news, streaming movies, using BitTorrent, or listening to music on the web all require that your device pull down data more or less continuously. With that in mind, we've settled on download speeds as the most important benchmark.
Without a VPN, your connection is fully open. Your ISP, employer, the Wi-Fi router in the coffee shop mentioned above, any server along the way, or a person with the right tools can look at your data, log it and use it in ways you can’t control. Government agencies can monitor your online activity and share the retained metadata with each other, including across country borders through intelligence alliances such as “14 Eyes.” Based on your IP address, which depends on your geographic location, third-party sites and services may charge different prices or display intrusive targeted advertising.
If you’re seriously concerned about government surveillance—we explain above why that should be most people’s last consideration when choosing a VPN—some expert sites like privacytools.io recommend avoiding services with a corporate presence in the US or UK. Such experts warn about the “14 eyes,” a creepy name for a group of countries that share intelligence info, particularly with the US. IVPN is based in Gibraltar, a British Overseas Territory. We don’t think that makes you any worse off than a company based in Switzerland, Sweden, or anywhere else—government surveillance efforts around the world are so complicated and clandestine that few people have the commitment, skills, or technology to avoid it completely. But because Gibraltar’s status has been a topic of debate in other deep dives on VPNs, we’d be remiss if we didn’t mention it.
Early data networks allowed VPN-style remote connections through dial-up modem or through leased line connections utilizing Frame Relay and Asynchronous Transfer Mode (ATM) virtual circuits, provided through networks owned and operated by telecommunication carriers. These networks are not considered true VPNs because they passively secure the data being transmitted by the creation of logical data streams. They have been replaced by VPNs based on IP and IP/Multi-protocol Label Switching (MPLS) Networks, due to significant cost-reductions and increased bandwidth provided by new technologies such as digital subscriber line (DSL) and fiber-optic networks.
Nevertheless, the point of a VPN is to remain private and to have your internet activity kept as private as possible. For that reason, we’re choosing Mullvad as the best overall VPN (see our full review of Mullvad). The interface needs a lot of work, but the company does a great job at privacy. Mullvad doesn’t ask for your email address, and you can mail your payment in cash if you want to. Like many other VPNs, Mullvad has a no-logging policy and doesn’t even collect any identifying metadata from your usage.
This is also a good way to provide support for more than one family member on a single subscription. Generally, there's no good reason for a VPN provider to allow less than two or three connections. If your provider only allows one, find another vendor. We gave extra points in our VPN directory to those vendors who allowed three or more connections.
When you download a file from a server without a VPN, there’s a chance you will encounter network congestion, most likely on your nearby ISP network or at the download server itself. When you use a VPN service, you add a third potential bottleneck to the route. Whether because of server load or congestion on the network surrounding the server, there’s a higher chance that your speed will be affected while connected to a VPN.
Then there’s the widespread surveillance by local and foreign governments. Through the Snowden leaks and years of follow-up reporting, we know that the worldwide surveillance structure is vast in scope and reach. While it would be illegal for police officers to search your home without a warrant, your browsing activity, messages, social media content, and other online information can be monitored, retained and shared among various government agencies, including across country borders.
Our results were similar in other parts of the world, with IVPN ranking near the top regardless of the test, day, or time. The exception was in Asia, where its Hong Kong servers didn’t perform well. At the time of our initial tests in spring of 2018, IVPN didn’t offer any other servers in Asia aside from Hong Kong. Since then, the company has added locations in Singapore and Tokyo, but we haven’t run a new series of standardized tests with either location.
Since we first recommended IVPN in the spring of 2018, the company has added automatic server selection to its desktop applications, bringing it in line with other top-performing VPN apps. Alternatively, when you click on the location at the bottom of the app, you’ll see a list of all of the global IVPN server locations, color coded by speed. At the top of the list is an option to connect to the fastest one, and once selected, the app remembers your preference through future disconnects and reboots. You can also use IVPN’s multihop servers to route your traffic through two VPN servers—a feature unique to IVPN among the services we tested—though we don’t think this step is necessary for most people, given the slower speeds you’ll likely experience.
For VPN connections, however, IP datagrams sent across the Internet can arrive in a different order from the one in which they were sent, and a higher proportion of packets can be lost. Therefore, for VPN connections, MPPE changes the encryption key for each packet. The decryption of each packet is independent of the previous packet. MPPE includes a sequence number in the MPPE header. If packets are lost or arrive out of order, the encryption keys are changed relative to the sequence number.
Voluntary tunneling occurs when a client computer or routing server creates a virtual connection to the target tunnel server. To accomplish this, tunneling client software and the appropriate tunneling protocol must be installed on the client computer. For the protocols discussed in this technical reference, voluntary tunnels require an IP connection (either LAN or dial-up).
Another unique aspect of VyprVPN is that they offer a powerful obfuscation feature called the Chameleon Protocol. This is a self-developed OpenVPN protocol that obfuscates (hides) VPN traffic to appear like regular HTTPS traffic. The Chameleon Protocol allows you to use the VPN in locations where VPNs are normally blocked, such as in China, schools, libraries, work networks, and with some streaming services like BBC iPlayer.
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.
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.
The IVPN app's default settings are great for most people, who should be happy just smashing the Connect button and not fiddling with settings. On a desktop or an Android device, the company supports only the OpenVPN protocol we recommend and uses AES 256-bit encryption (what we consider the standard at this point). Our budget pick, TorGuard, defaults to the weaker (but also acceptable) AES 128-bit encryption unless you manually change it.
While it hides your IP address, a VPN is not a true anonymization service. For that, you'll want to access the Tor network, which will almost certainly slow down your connection. While a VPN tunnels your web traffic to a VPN server, Tor bounces around your traffic through several volunteer nodes making it much, much harder to track. Using Tor also grants access to hidden Dark Web sites, which a VPN simply cannot do. That said, some services, such as NordVPN, offer Tor access on specific servers. IVPN offers a similar feature called multi-hop VPN, which lets you route your web traffic in tricky ways.
