We summarize the protocols above, and look at them in detail in VPN Encryption: The Complete Guide. Although L2TP/IPsec is fine for most purposes, we only really recommend OpenVPN and IKEv2. OpenVPN is very secure if properly configured. Indeed, Edward Snowden’s documents showed that even the NSA can’t crack well-implemented OpenVPN. It is also supported by almost every provider.  But it is relatively slow. The newer IKEv2 is much faster and is considered secure, but has not been battle-tested in the way that OpenVPN has. It is not as well supported at present, although it is increasingly popular with providers thanks to its speed advantages over OpenVPN.
Security is second to none with NordVPN. Its kills switch feature always monitors traffic between devices and the VPN servers. If for some reason, the data stream breaks, the kill switch will automatically terminate the connection, ensuring that your traffic is protected from prying eyes. Also, a DNS leak feature changes your DNS to point to the VPN server, ensuring that hackers cannot steal data from your default DNS.

Israel-based Hola isn’t a traditional VPN in which customers connect to a network of centralized servers owned by the VPN company. Instead, Hola users connect to each other, using other users’ idle bandwidth as part of a large peer-to-peer network. Obviously, this comes with some pretty big security and legal concerns. Users could use each other’s internet for illegal activity, for example. In 2015, Hola used its user’s computers to create a botnet and perform a massive distributed denial-of-service (DDoS) attack. The abuse of customers’ trust happened entirely without their knowledge.
Finding the best free VPN is an exercise in balancing those restrictions. TunnelBear, for example, lets you use any server on its network but limits you to 500MB-1GB per month. Avira Phantom VPN lets you use as many devices as you like and any server you like, but also restricts you to 500MB per month. AnchorFree Hotspot Shield also places no limits on the number of devices, but restricts you to 500MB per day and only US-based servers. Kaspersky Secure Connection also doesn't limit your devices but doesn't let you choose a VPN server—the app does it automatically.
Tunneling protocols can operate in a point-to-point network topology that would theoretically not be considered as a VPN, because a VPN by definition is expected to support arbitrary and changing sets of network nodes. But since most router implementations support a software-defined tunnel interface, customer-provisioned VPNs often are simply defined tunnels running conventional routing protocols.
We also like how easy it is to connect, and how clear and accessible the settings are, on all platforms when using the IVPN app. (ChromeOS has an option to use a less-secure VPN protocol with most providers, including IVPN. But TorGuard, our budget pick, supports the more secure OpenVPN on Chromebooks and tablets.) If you do want to tweak some settings, IVPN has easy-to-understand checkboxes for most options. For example, the kill switch (labeled “firewall”) has an easy on/off toggle. Anytime it’s on and the app is open, all traffic in and out of your computer will cut off if you forget to connect to the service or the secure connection drops for some reason.
NordVPN’s customer service is also quite good. They offer 24/7 live chat support directly through their website and many support guides and tutorials. Right now NordVPN is extending the 75% discount price exclusively for three-year plans. All subscriptions come with a 30 day money-back guarantee, allowing you to try the service risk free. [Learn more >]
With a StrongVPN account, customers have the ability to choose which server location they want, even down to the specific city. This type of personalized, user-friendly service is also seen with their unlimited server switching, as well as the ability to have up to six simultaneous connections on different devices. StrongVPN supports Mac, Windows, iOs, Android, and even multiple routers, which is a huge plus. 
Depending on how ISPs respond to a newly deregulated environment, a VPN could tunnel traffic past any choke points or blockades thrown up by ISPs. That said, an obvious response would be to block or throttle all VPN traffic. Or perhaps ISPs will come up with an entirely novel way to monetize the letitude given them by the current lack of net neutrality legislation.
Since we're living in a connected world, security and privacy are critical to ensure our personal safety from nefarious hacks. From online banking to communicating with coworkers on a daily basis, we're now frequently transferring data on our computers and smartphones. It's extremely important to find ways of securing our digital life and for this reason, VPNs have become increasingly common.
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. The desktop app defaults to a secure OpenVPN connection with AES 256-bit encryption (what we consider the standard at this point), and the mobile app can (and should) be toggled to OpenVPN as well. Our budget pick, TorGuard, defaults to the weaker (but also acceptable) AES 128-bit encryption unless you manually change it, and hasn’t added OpenVPN support on its iOS app.
Don't mistake the cartoony layout of the TunnelBear VPN Android app — it's a simple-to-use app that offers serious VPN protection. You can create an account for free, which gives you 500MB of secure data a month but we'd recommend checking out a paid subscription that lets you connect up to five different devices at a time to servers in 20 different countries.
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.

The app likewise prevents websites from collecting users’ private data, allowing for safer and more secure web browsing. To make things even better, the solution automatically connects whenever an unsecure Wi-Fi connection is detected, ensuring constant protection. It connects to the nearest server, resulting in optimum speeds. But one can also connect manually and be able to choose a preferred server.
It can be quite simple to watch Netflix and other restricted goodies. You'll have to use a VPN service that allows you to get a unique IP address. This can often be available for an additional fee. Look for VPN services that offer a "dedicated IP address", "dedicated IP", or "static IP." Additional features like these will always allow you to access content from Netflix through a VPN service.
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.
