Many VPN services also provide their own DNS resolution system. Think of DNS as a phone book that turns a text-based URL like "pcmag.com" into a numeric IP address that computers can understand. Savvy snoops can monitor DNS requests and track your movements online. Greedy attackers can also use DNS poisoning to direct you to bogus phishing pages designed to steal your data. When you use a VPN's DNS system, it's another layer of protection.
Recall that when you're online and connected to an internet application through a VPN, there are a few things happening: Your data from your computer to the VPN service is encrypted by the VPN. Your data from the VPN service to the internet application may or may not be encrypted via https, but it's not encrypted by the VPN service. And your IP address is spoofed. The online application sees the IP address of the VPN service, not of your laptop.
We have often said that having to choose between security and convenience is a false dichotomy, but it is at least somewhat true in the case of VPN services. When a VPN is active, your web traffic is taking a more circuitous route than usual, often resulting in sluggish download and upload speeds as well as increased latency. The good news is that using a VPN probably isn't going to remind you of the dial-up days of yore.
Using a VPN is a little trickier for ChromeOS users, however. While Google has worked to make it easier to use a VPN with a Chromebook or Chromebox, it's not always a walk in the park. Our guide to how to set up a VPN on a Chromebook can make the task a bit easier, however. In these cases, you might find it easier to install a VPN plug-in for the Chrome browser. This will only secure some of your traffic, but it's better than nothing.

Final Verdict – NordVPN is easily one of the best all-around providers. I would especially recommend this VPN for users that value their privacy. The encryption protocols, jurisdiction, and logging policies of NordVPN make it the perfect VPN for users concerned about their privacy. And its Double VPN feature makes it stand out from the crowd, something I have covered in detail in NordVPN review.


Given the aggressive pricing and marketing of other services that don’t measure up to our picks, IVPN’s most obvious downside may look like its price: At the time of this writing, the regular price for an annual IVPN subscription is $100 (about $8 per month). Promotions regularly bringing that down to $70 to $80 per year, but some services have regular pricing of half that. But you shouldn’t pay for a VPN you can’t trust, or one so slow or confusing that you avoid using it at all. We think IVPN’s combination of trust, security, and performance is worth the price. But if it’s too expensive for your needs, consider our budget pick instead.
With the service, user data cannot be intercepted as all traffic are encrypted. A split tunneling functionality allows users to route traffic from specific applications through the software. It likewise has a kill switch, which effectively cuts off Internet connection when the VPN connection fails. This prevents the accidental revelation of IP addresses.

MPPE provides only link encryption between the VPN client and the VPN server. It does not provide end-to-end encryption, which is data encryption between the client application and the server hosting the resource or service that is being accessed by the client application. If end-to-end encryption is required, IPSec can be used to encrypt IP traffic from end-to-end after the PPTP tunnel is established.

Corporate and Exit Locations: Depending on what you’re using a VPN for, your service’s location—and the exit locations you can choose—are important to consider. If you want to get around a location restriction and watch live TV in the UK, for example, you want to make sure your VPN service provider has servers in the UK. If you’re concerned about privacy or state-sponsored snooping, you may want to pick a service operated outside of your home country. Similarly, if the service is based on the US, they’re subject to US laws, and may be forced to turn over usage data to the authorities upon request. Many people make more of this than they should (we’ve seen overseas services turn over their data to friendly governments without any hesitation repeatedly), but it’s important to make sure a VPN has servers in multiple locations—or at least the location you’re interested in—when shopping.

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.
Over the course of four months, we scoured articles, white papers, customer reviews, and forums to compile the pros and cons of VPN services and different VPN protocols and encryption technologies. That One Privacy Site and privacytools.io stood out as two of the most thorough and unbiased sources of information. We interviewed Electronic Frontier Foundation analyst Amul Kalia about government surveillance and VPN efficacy. We also got answers from Joseph Jerome, policy counsel for the Center for Democracy & Technology’s privacy and data project, about how accountable VPN providers are for their policies and terms of service, and how that relates to trustworthiness. Alec Muffett, a security expert and software engineer, also shared his views on the usefulness of VPNs to protect against various threats.

When choosing your VPN, do your research and mind the legal aspects. Countries like Germany, France or Japan are cracking down on copyright infringement, while the members of the 14 Eyes treaty have draconian data retention laws and extensive surveillance. So, if you’re looking to maximize your privacy, you might want to avoid connecting to servers in those countries.


VPN is used to hide/change your IP and encrypt your online data packets. That is the core purpose of using a VPN. But can it protect you from the online viruses that enter your system through a downloaded file, a click on a wrong link or an infected USB? It doesn’t matter if you using a slow VPN or a Fast VPN, saving your device from latest viruses is not a VPN is built for. However, antivirus software is advisable if you want to protect your device from viruses.

Access to Netflix and other streaming services is rock solid thanks to dedicated streaming servers. Torrenting/Kodi performance is equally good except on US servers, where P2P traffic is sadly banned. Download speeds on local connections are typically over 128Mbps and while they drop off on international servers, it’s always enough for HD streaming.


Initially, the routing table for each router includes only the networks that are physically connected. A RIP router periodically sends announcements that contain its routing table entries to inform other local RIP routers of the networks it can reach. RIP version 1 uses IP broadcast packets for its announcements. RIP version 2 can use multicast or broadcast packets for its announcements.

We asked TorGuard detailed questions about the company’s internal policies and standards, just as we did with five other top-performing services. TorGuard CEO Benjamin Van Pelt answered all our questions, as he has done for other outlets multiple times since the company launched in 2012. Though TorGuard’s answers weren’t as in-depth as some other companies’ responses, Van Pelt is a public figure who has been willing to talk about TorGuard’s operations at length. In 2013, ArsTechnica got a close look at TorGuard’s engineering and network management skills as the company rebuffed repeated attacks on its servers. Even though the company’s marketing is wrought with overreaching claims about being “anonymous”—an inaccurate boast that makes some experts cringe—the technical and operational standards of the company are focused on protecting customer privacy. In one interview with Freedom Hacker, Van Pelt notes that if there were problems on a server, such as someone using it for spamming, the company couldn’t restrict a single user. “Rules would be implemented in that specific server which would limit actions for everyone connected, not just one user. Since we have an obligation to provide fast, abuse free services, our team handles abuse reports per server – not per single user.”
Subscription VPN Providers usually take your privacy a bit more seriously, since you’re paying for the service. It’s unusual for them to show ads, although whether they do logging or store data about your usage varies from company to company. They usually offer free trials so you can give the service a shot first, but remember: just because you’re paying for a service doesn’t mean you shouldn’t do your homework.
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.

Aside from providing an exceptional VPN server for encrypting traffic, Speedify leverages all types of available internet connection to increase bandwidth, bolster internet speeds, and lower latency. This results in a smooth and reliable connection on any platform, whether using mobile devices or a desktop. This is achieved through its Channel Bonding functionality that combines all types of internet connections, including WiFI, VPN, 3G, and, 4G.
Though TorGuard’s support site offers in-depth information, finding specific info is harder, and the site is not as easy to follow as those for our top pick or ExpressVPN. TorGuard provides helpful video tutorials, but they’re two years old now and don’t show the latest versions of the company’s apps. As with most of the VPNs we contacted, TorGuard support staff responded to our help ticket quickly—the response to our query came less than half an hour after we submitted it on a weekday afternoon. Still, if you’re worried about getting lost in VPN settings or don’t like hunting for your own answers, IVPN is a better fit.
IVPN also performed well in our speed tests. Though it wasn't always the fastest in the 54 measurements we took on each service, it ranked near the top on many servers at different times of the week—especially compared with the most trustworthy services. Private Internet Access, one of the most visible, privacy-focused VPNs, had slower speeds when connecting to most servers and less reliable connections than IVPN. For US servers (which we expected to be the fastest locations because we tested from California), IVPN ranked behind only OVPN and TorGuard. We liked OVPN—especially its speed results—but we thought that company's small team and small selection of servers and locations were too limiting for some people.

If a VPN client that uses a PPTP connection is behind a NAT, the NAT must include a NAT editor that can translate PPTP traffic. The NAT editor is required because tunneled PPTP data has a GRE header rather than a TCP header or a UDP header. The NAT editor uses the Call ID field in the GRE header to identify the PPTP data stream and translate IP addresses and call IDs for PPTP data packets that are forwarded between a private network and the Internet.


A powerful VPN service, Hotspot Shield is ideal for those who enjoy using public Wi-Fi. It is basically a free VPN that comes in the form of an application or as a browser extension. Security is assured as the service uses OpenVPN , which makes use of the same encryption as HTTPS does. This feature is particularly effective in protecting credit card information during online purchases.
The quality of customer support may be excellent but responses can be slow. It’s not the best option for China either. So while NordVPN falls a little short of ExpressVPN overall, on a two-year subscription, it works out a lot cheaper at $3.99 per month. So if you want to keep monthly costs down or only care about core performance, NordVPN is the ideal choice.
In an overcrowded VPN market, ExpressVPN continues to stand out from the rest and remains the top recommendation at Restore Privacy. It is based in the British Virgin Islands and offers secure, user-friendly apps for all devices. Extensive testing for the ExpressVPN review found it to be very secure, with exceptional speeds and reliability throughout the server network.

Our VPN-issued IP address was never blacklisted by websites like those of Yelp and Target, but we were unable to access Netflix and BBC iPlayer while connected to TorGuard. No VPN offers a reliable way to access these streaming services, though: All of the VPNs we tried were blocked by Netflix, and of the four that could access BBC content on the first day, two were blocked the next.
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.

Put simply, a Virtual Private Network, or VPN, is a group of computers (or discrete networks) networked together over a public network—namely, the internet. Businesses use VPNs to connect remote datacenters, and individuals can use VPNs to get access to network resources when they’re not physically on the same LAN (local area network), or as a method for securing and encrypting their communications when they’re using an untrusted public network.

However, if you’re using a top-tier VPN service, the difference in speed usually isn’t noticeable, and can sometimes speed up your connection. You can still watch streaming videos and download large files without interruption. Our VPN servers are among the fastest in the industry and we work hard to keep it that way. Download Hotspot Shield VPN and get privacy protection without sacrificing speed.

And if you’re looking for mobile VPNs, we’ve compiled the best VPNs for Android and the best VPNs for iPhone. For your local network, it might even be easier to set up a VPN on your router 4 Reasons to Set Up a VPN on Your Router (Instead of Your PC) 4 Reasons to Set Up a VPN on Your Router (Instead of Your PC) You use a VPN, but is it practical to use it on several devices when you could simply set it up on a VPN? The choice is yours. Here's what you need to know. Read More .


Our Findings: During our VPN speed test, we have switched in between different ExpressVPN servers to determine the latency; however, UK was the one we tested several times. We noticed that despite choosing a distant location, ExpressVPN servers manage to deliver fast VPN speed, and the drop was not more than 15%, which is normal. Also, we didn’t experience any connection interruption throughout the test phase. It clearly states that ExpressVPN’s server are smartly optimized to give best streaming experience for Netflix, Hulu, HBO, BBC iPlayer and other media websites.
IVPN exceeded our requirements for being trustworthy and transparent. It also offers good performance without sacrificing security, and it's easy to set up and use on nearly any device running Windows, macOS, Android, or iOS. Other VPNs we tested had faster connections at particular server locations or lower prices, but they came up short on essential factors such as transparency about who exactly runs them. If you're ready for a VPN, we think IVPN is worth the price, even considering competitors with cheaper options. If you're not ready to commit, you can try it out with a seven-day money-back guarantee. It's easy and obvious to turn off automatic billing, too.
The cause of this performance improvement was not immediately discernible. Experts I have spoken to have suggested the test cheating or data compression mentioned above. It was also suggested that, perhaps, some VPN companies had access to higher bandwidth connections in their networks. Another possibility was that our DSL line was artificially capped and that the VPN allowed our data to bypass that restriction.
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.
Password Authentication Protocol (PAP) is a clear-text authentication scheme. The NAS requests the user name and password, and PAP returns them in clear text (unencrypted). Obviously, this authentication scheme is not secure because a malicious user could capture the user's name and password and use it to get subsequent access to the NAS and all of the resources provided by the NAS. PAP provides no protection against replay attacks or remote client impersonation once the user's password is compromised.

It is our business to make safety and caution for our free VPN service the number one priority. We are constantly working to understand and develop new technology that keeps our users safe, without requiring costly fees or lengthy sign-up features. We want to keep you and your family safe without you having to give up any freedom. We would never limit these rights and don’t believe in setting limits. That is not our business.


You want to skip PPTP if at all possible. It’s a very dated protocol that uses weak encryption and due to security issues should be considered compromised. It might be good enough to secure your non-essential web browsing at a coffee shop (e.g. to keep the shopkeeper’s son from sniffing your passwords), but it’s not up to snuff for serious security. Although L2TP/IPsec is a significant improvements over PPTP, it lacks the speed and the open security audits found with OpenVPN.


When we test VPNs, we use the Ookla speed test tool. (Note that Ookla is owned by PCMag's publisher, Ziff Davis.) This test provides metrics for latency, download speeds, and upload speeds. Any one of these can be an important measurement depending on your needs, but we tend to view the download speed as the most important. After all, we live in an age of digital consumption.
