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.
If you need a more affordable VPN than our top pick and don’t have an Apple device—or if you need ChromeOS support—we recommend TorGuard. Its apps aren’t as simple or user-friendly, but TorGuard is a good option for more tech-savvy people or those willing to spend a little more time fiddling with an app. TorGuard’s CEO has built trust by talking with media outlets (including us) and detailing the company’s commitment to a service built around a lack of activity logs. Though the apps aren’t as easy to use as our top pick, the connections were the fastest of any we tested and the company has more than twice as many server locations.
The problem with anonymity is there are so many issues to consider—most of which are beyond the scope of this article. Has the government surreptitiously installed malware on your PC in order to monitor your activity, for example? Does the VPN you want to use have any issues with data leakage or weak encryption that could expose your web browsing? How much information does your VPN provider log about your activity, and would that information be accessible to the government? Are you using an anonymous identity online on a PC that you never use in conjunction with your actual identity?
In the most recent round of testing, we've also looked at how many virtual servers a given VPN company uses. A virtual server is just what it sounds like—a software-defined server running on server hardware that might have several virtual servers onboard. The thing about virtual servers is that they can be configured to appear as if they are in one country when they are actually being hosted somewhere else. That's an issue if you're especially concerned about where you web traffic is traveling. It's a bit worrisome to choose one location and discover you're actually connected somewhere else entirely.
For inbound traffic, when the tunneled data is decrypted by the VPN server it is forwarded to the firewall, which employs its filters to allow the traffic to be forwarded to intranet resources. Because the only traffic that is crossing the VPN server is traffic generated by authenticated VPN clients, firewall filtering in this scenario can be used to prevent VPN users from accessing specific intranet resources.
Torrenting/P2P support – Getting torrents to work with PIA is no problem. You can easily gain access to P2P sites and clients with PIA if they are blocked in your region. As with IPVanish, however, PIA complies with the DMCA (Digital Millennium Copyright Act) which protects the copyrights of content creators. Therefore, PIA should be avoided if you are looking for a safe to torrent.
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.
When we say that in theory VPNs can’t be intercepted, that’s because VPNs are like any other form of security: if you use them on a device that’s already been compromised by malware such as keyloggers or other security threats then they can’t do their job properly. If you’re on Windows, then good quality, up to date anti-virus software isn’t a luxury. It’s absolutely essential.

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.
The VPN server can be configured to use either Windows or Remote Authentication Dial-In User Service (RADIUS) as an authentication provider. If Windows is selected as the authentication provider, the user credentials sent by users attempting VPN connections are authenticated using typical Windows authentication mechanisms, and the connection attempt is authorized using the VPN client’s user account properties and local remote access policies.
VPN was not the first technology to make remote connections. Several years ago, the most common way to connect computers between multiple offices was by using a leased line. Leased lines, such as ISDN (integrated services digital network, 128 Kbps), are private network connections that a telecommunications company could lease to its customers. Leased lines provided a company with a way to expand its private network beyond its immediate geographic area. These connections form a single wide-area network (WAN) for the business. Though leased lines are reliable and secure, the leases are expensive, with costs rising as the distance between offices increases.
Because the firewall does not have the encryption keys for each VPN connection, it can only filter on the plaintext headers of the tunneled data, meaning that all tunneled data passes through the firewall. However, this is not a security concern because the VPN connection requires an authentication process that prevents unauthorized access beyond the VPN server.
We contacted each of our finalists with simple questions about its service and troubleshooting. Most VPN companies provide technical support through online ticketing systems, meaning you'll need to wait for a response. This means that self-help support sites are even more important, because waiting for a reply while your connection is down can be frustrating. Response times to our support inquiries ranged from 20 minutes to a day.
We’ve shown you how to build your own VPN for remote gaming and browsing that also protects your security, shown you how to make a VPN even more secure, and shown you dozens of services that operate free and paid VPNs you can sign up for and use. We’ve even put the question to you several times to tell us which VPN service providers you think are the best. So how do you pick a solid VPN service?
Cost: PureVPN is much more affordable than most providers and gives a myriad of payment options, like credit card, PayPal, Alipay, CoinPayments, Cashu, Payment Wall, BlueSnap, and more. You can purchase a one-year plan for $5.41/month, a two-year plan for $3.54/month, or pay monthly for $10.95/month. PureVPN is also currently running special pricing of $2.92/month for a 3 year plan when you pay $105 every three years.
Increasingly, mobile professionals who need reliable connections are adopting mobile VPNs.[need quotation to verify] They are used for roaming seamlessly across networks and in and out of wireless coverage areas without losing application sessions or dropping the secure VPN session. A conventional VPN can not withstand such events because the network tunnel is disrupted, causing applications to disconnect, time out, or fail, or even cause the computing device itself to crash.
The encryption and decryption processes depend on both the sender and the receiver having knowledge of a common encryption key. Intercepted packets sent along the VPN connection in the transit network are unintelligible to any computer that does not have the common encryption key. The length of the encryption key is an important security parameter. Computational techniques can be used to determine the encryption key. Such techniques require more computing power and computational time as the encryption key gets larger. Therefore, it is important to use the largest possible key size.
A lot of people avoid using VPN providers based out of the United States on the premise that US law would compel those providers to log all VPN activity. Counterintuitively, there are no such data logging requirements for US-based VPN providers. They might be compelled under another set of laws to turn over data if they have any to turn over, but there is no requirement they even keep the data in the first place.
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.
