VPNs Keep You Safe Online
Are you so used to your data traveling over Wi-Fi that you’ve forgotten to worry about the security of that data—and about who else might be spying on it, or even stealing it for nefarious purposes? If so, you are—sadly—in the majority, and you ought to consider using a viritual private network, or VPN. In fact, we found that a dismal 71 percent of the 1,000 respondents had never used a VPN. Even among those who support net neutrality—who you might think would tend to be well informed on technology and privacy issues—only 45 percent had used a VPN.
That attitude to the safety and privacy of personal data creates an enormous online security risk. Public Wi-Fi networks, which are ubiquitous and convenient, are unfortunately also highly convenient for attackers looking to compromise your personal information. How do you know, for example, that “starbucks_wifi_real” is actually the Wi-Fi network for the coffee shop? Anyone could have created that network, and they may have done so in order to lure victims into disclosing personal information over it. In fact, a popular security researcher prank is to create a network with the same name as a free, popular service and see how many devices will automatically connect because it appears safe.
Even if you’re inclined to trust your fellow humans (which I do not recommend), you still shouldn’t trust your internet service provider. In its infinite wisdom, Congress has decided that your ISP is allowed to sell your browsing history.
In short, it’s time to start thinking about protecting your personal information. That’s where virtual private networks, or VPNs, come in. These services use simple software to protect your internet connection, and they give you greater control over how you appear online, too. While you might never have heard of VPN services, they are valuable tools that you should understand and use. So who needs a VPN? The short answer is that everyone does. Even Mac users can benefit from a VPN.
What Is a VPN?
In the simplest terms, a VPN creates a secure, encrypted connection—which can be thought of as a tunnel—between your computer and a server operated by the VPN service. In a professional setting, this tunnel effectively makes you part of the company’s network, as if you were physically sitting in the office.
While you’re connected to a VPN, all your network traffic passes through this protected tunnel, and no one—not even your ISP—can see your traffic until it exits the tunnel from the VPN server and enters the public internet. If you make sure to only connect to websites secured with HTTPS, your data will continue to be encrypted even after it leaves the VPN.
Think about it this way: If your car pulls out of your driveway, someone can follow you and see where you are going, how long you are at your destination, and when you are coming back. They might even be able to peek inside your car and learn more about you. With a VPN service, you are essentially driving into a closed parking garage, switching to a different car, and driving out, so that no one who was originally following you knows where you went.
VPN services, while tremendously helpful, are not foolproof. There’s no magic bullet (or magic armor) when it comes to security. A determined adversary can almost always breach your defenses in one way or another. Using a VPN can’t help if you unwisely download ransomware on a visit to the Dark Web, or if you foolishly give up your data to a phishing attack. What a VPN can do is to protect you against mass data collection and the casual criminal vacuuming up user data for later use. It can also protect your privacy by making it harder for advertisers to figure out who and where you are.
Who Needs a VPN?
First and foremost, using a VPN prevents anyone on the same network access point (or anywhere else) from intercepting your web traffic in a man-in-the-middle attack. This is especially handy for travelers and for those using public Wi-Fi networks, such as web surfers at hotels, airports, and coffee shops. Someone on the same network, or the person in control of the network you’re using, could conceivably intercept your information while you’re connected.
VPNs also cloak your computer’s actual IP address, hiding it behind the IP address of the VPN server you’re connected to. IP addresses are distributed based on location, so you can estimate someone’s location simply by looking at their IP address. And while IP addresses may change, it’s possible to track someone across the internet by watching where the same IP address appears. Using a VPN makes it harder for advertisers (or spies, or hackers) to track you online.
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.
VPNs are necessary for improving individual privacy, but there are also people for whom a VPN is essential for personal and professional safety. Some journalists and political activists rely on VPN services to circumvent government censorship and safely communicate with the outside world. Check the local laws before using a VPN in China, Russia, Turkey, or any country with with repressive internet policies.
What about using a VPN for BitTorrent? Some services, such as TorGuard and NordVPN, allow peer-to-peer file sharing and the use of BitTorrent sharing. Others restrict such activity to specific servers. Be smart: Learn the company’s terms of service—and the local laws on the subject. That way you can’t complain if you run into trouble.
It is also possible (emphasis on “possible”) that VPNs may be able to save net neutrality repeal. Kind of. For those who are unaware, net neutrality is the much-discussed concept that ISPs treat web services and apps equally, and not create fast lanes for companies that pay more, or require consumers to sign up for specific plans in order to access services like Netflix or Twitter. 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. We’ll have to see how this plays out.
How to Choose a VPN Service
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.
In fact, not all VPN services require that you pay. Several services we’ve listed here also have free VPN offerings. You tend to get what you pay for, as far as features and server locations go, but if your needs are basic, a free service can still keep you safe. TunnelBear and ProtonVPN, for example, offer limited but serviceable free VPNs.
Some VPN services provide a free trial, so take advantage of it. Make sure you are happy with what you signed up for, and take advantage of money-back guarantees if you’re not. This is actually why we also recommend starting out with a short-term subscription—a week or a month—to really make sure you are happy. KeepSolid VPN Unlimited offers a one-week Vacation subscription, for example. Yes, you may get a discount by signing up for a year, but that’s more money at stake should you realize the service doesn’t meet your performance needs.
Most users want a full graphical user interface for managing their VPN connection and settings, though a few would rather download a configuration file and import it into the OpenVPN client. Most VPN companies we have reviewed support all levels of technological savvy, and the best have robust customer support for when things go sideways.
Can You Trust Your VPN Service?
If you’re using a service to route all your internet traffic through its servers, you have to be able to trust the provider. Established security companies, such as F-Secure, may have only recently come to the VPN market. It’s easier to trust companies that have been around a little longer, simply because their reputation is likely to be known. But companies and products can change quickly. Today’s slow VPN service that won’t let you cancel your subscription could be tomorrow’s poster child for excellence.
We’re not cryptography experts, so we can’t verify all of the encryption claims providers make. Instead, we focus on the features provided. Bonus features like ad blocking, firewalls, and kill switches that disconnect you from the web if your VPN connection drops, go a long way toward keeping you safe. We also prefer providers that support OpenVPN, since it’s a standard that’s known for its speed and reliability. It’s also, as the name implies, open source, meaning it benefits from many developers’ eyes looking for potential problems.
Since we last tested VPNs, we’ve given special attention to the privacy practices of VPN companies and not just the technology they provide. In our testing, we read through the privacy policies and discuss company practices with VPN service representatives. What we look for is a commitment to protect user information, and to take a hands-off approach to gathering user data.
As part of our research, we also make sure to find out where the company is based and under what legal framework it operates. Some countries don’t have data-retention laws, making it easier to keep a promise of “We don’t keep any logs.” It’s also useful to know under what circumstances a VPN company will hand over information to law enforcement and what information it would have to provide if that should happen.
While a VPN can protect your privacy online, you might still want to take the additional step of avoiding paying for one using a credit card, for moral or security reasons. Several VPN services now accept anonymous payment methods such Bitcoin, and some even accept retailer gift cards. Both of these transactions is about as close as you can get to paying with cash for something online. That Starbucks gift card may be better spent on secure web browsing than a mediocre-at-best latte.
Understanding the Limitations of a VPN
VPNs are great, but it’s just as important to know what a VPN can and cannot do. A tool is only useful when it’s used correctly, after all.
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.
Using a VPN will prevent most kinds of DNS attacks that would redirect you to a phishing page, but a regular old page made to look like a legit one in order to trick you into entering your data can still work. Some VPNs, and most browsers, are pretty good about blocking phishing pages, but this attack still claims too many victims to be ignored. Use common sense and be sure to verify that websites are what they say they are by looking carefully at the URL and always visiting HTTPS sites.
In addition to blocking malicious sites and ads, some VPNs also claim to block malware. We don’t test the efficacy of these network-based protections, but most appear to be blacklists of sites known to host malicious software. That’s great, but don’t assume it’s anywhere near as good as standalone antivirus. Use this feature to complement, not replace, your antivirus.
Lastly, keep in mind that some security conscious companies like banks may be confused by your VPN. If your bank sees you logging in from what appears to be another US state or even another country, it can raise red flags. Expect to see captchas and more frequent multifactor requests when your VPN is on.
VPNs by the Numbers
Some important things to look for when shopping for a VPN are the number of licenses for simultaneous connections that come with your fee, the number of servers available, and the number of locations in which the company has servers. It all comes down to numbers.
Most VPN services allow you to connect up to five devices with a single account. Any service that offers fewer connections is outside the mainstream. Keep in mind that you’ll need to connect every device in your home individually to the VPN service, so just two or three licenses won’t be enough for the average nested pair. Note that many VPN services offer native apps for both Android and iOS, but that such devices count toward your total number of connections.
Of course, there are more than just phones and computers in a home. Game systems, tablets, and smart home devices such as light bulbs and fridges all need to connect to the internet. Many of these things can’t run VPN software on their own, nor can they be configured to connect to a VPN through their individual settings. In these cases, you may be better off configuring your router to connect with the VPN of your choice. By adding VPN protection to your router, you secure the traffic of every gadget connected to that router. And the router—and everything protected by it—uses just one of your licenses. Nearly all of the companies we have reviewed offer software for most consumer routers and even routers with preinstalled VPN software, making it even easier to add this level of protection.
When it comes to servers, more is always better. More servers mean that you’re less likely to be shunted into a VPN server that is already filled to the brim with other users. NordVPN, Private Internet Access, and TorGuard currently lead the pack with well over 3,000 servers each—NordVPN is at the forefront with 4,875 servers. But the competition is beginning to heat up. Last year, only a handful of companies offered more than 500 servers, now it’s becoming unusual to find a company offering fewer than 1,000 servers.
The number and distribution of those servers is also important. The more places a VPN has to offer, the more options you have to spoof your location! More importantly, having numerous servers in diverse locales means that no matter where you go on Earth you’ll be able to find a nearby VPN server. The closer the VPN server, the better the speed and reliability of the connection it can offer you. Remember, you don’t need to connect to a far-flung VPN server in order to gain security benefits. For most purposes, a server down the street is as safe as one across the globe.
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.
What’s the Fastest VPN?
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.
Most services provide perfectly adequate internet speed when in use, and can even handle streaming HD video. However, 4K video and other data-intensive tasks like gaming over a VPN are another story. Some VPN services, such as NordVPN, have started to roll out specialty servers for high-bandwidth activities. And nearly every service we have tested includes a tool to connect you with the fastest available network. Of course, you can always limit your VPN use to when you’re not on a trusted network.
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.
Our speed tests stress comparison and reproducibility. That means we stand by our work, but your individual results may vary. After all, perhaps you live on top of a VPN server, or just happen to have a super-high bandwidth connection.
What follows are the results from our top-rated VPNs as of May, 2018.
All that being said, we currently name TorGuard as the fastest VPN service. It doesn’t take the top spot in all of our tests, but has remarkably low latency and had the best performance in the all-important download tests. Fittingly, it offers many add-ons such as dedicated IP addresses that, along with its speed, will appeal to the BitTorrent users it is designed to protect.
Can I Use a VPN for Netflix?
Borders still exist on the web, in the form of geographic restrictions for streaming content. The BBC iPlayer, for example, lets UK residents watch the Beeb to their heart’s content. The rest of the world, not so much. But if you were to select a VPN server in the UK, your computer’s IP address would appear to be the same as the server, allowing you to view the content.
The trouble is that Netflix and similar video streaming services are getting wise to the scam. In our testing, we found that Netflix blocks streaming more often than not when we were using a VPN. There are a few exceptions, but Netflix is actively working to protect its content deals. VPNs that work with Netflix today may not work tomorrow.
What’s the Best VPN For Kodi?
If you don’t know what Kodi is, you’re not alone. However, an analysis of searches leading to our site reveals that a surprising number of you are, in fact looking for VPN that works with the mysterious Kodi. Dictionary.com defines Kodi as a possible misspelling of “Jodi,” but PCMag analyst Ben Moore clarified for me that Kodi is “free, open-source software for managing your local collection of movies, television shows, music, and photos.”
With Kodi, you can access your media over a local connection (LAN) or from a remote media server, if that’s your thing. This is, presumably, where concerns about VPN enter the picture. A device using a VPN, for example, will have its connection encrypted on the local network. You might have trouble connecting to it. Using Chromecast on a VPN device just doesn’t work, for example. Kodi users might have the same issue.
For local VPN issues, you have a couple of options. First, consider installing VPN software on your router and not using a VPN on your local machines. Alternatively, many VPN services offer browser plug-ins that only encrypt your browser traffic. That’s not ideal from a security perspective, but it’s useful when all you need to secure is your browser information.
Some, but not all, VPN services will let you designate specific applications to be routed outside the encrypted tunnel. This means the traffic will be unencrypted, but also accessible locally.
If you’re trying to connect to a remote media source with Kodi, a VPN would likely play a different role. It might, for example, prevent your ISP from determining what you’re up to. It might also be useful if you’re connecting to a third-party service for Kodi that allows streaming of copyright-infringing material. Keep in mind, however, that some VPN services specifically forbid the use of their services for copyright infringement.
VPN for Windows 10 and Beyond
When we test VPNs, we generally start with the Windows client. This is often the most complete review, covering several different platforms as well as the service’s features and pricing in depth. That’s purely out of necessity, since most of our readers use Windows (although this writer is currently using a MacBook Air). We currently use a Lenovo ThinkPad T460s laptop running the latest version of Windows 10. We periodically upgrade to a newer machine, in order to simulate what most users experience.
But as you can see from the chart at the top, however, Windows is not the only platform for VPNs. The Android mobile operating system, for example, is the most widely used OS on the planet. So it makes sense that we also test VPNs for Android.
That’s not to ignore Apple users. We also review VPN clients for macOS and iOS.
Using a VPN is a little trickier for Chrome OS 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.
Finally, we have lately begun to review the best Linux VPN apps, too.
Using a Mobile VPN
We used to advise people to do banking and other important business over their cellular connection when using a mobile device, since it is generally safer than connecting with a public Wi-Fi network. But even that isn’t always a safe bet. Researchers have demonstrated how a portable cell tower, such as a femtocell, can be used for malicious ends. The attack hinges on jamming the LTE and 3G bands, which are secured with strong encryption, and forcing devices to connect with a phony tower over the less-secure 2G band. Because the attacker controls the fake tower, he can carry out a man-in-the-middle attack and see all the data passing over the cellular connection. Admittedly, this is an exotic attack, but it’s far from impossible.
Wi-Fi attacks, on the other hand, are probably far more common than we’d like to believe. While attending the Black Hat convention, researchers saw thousands of devices connecting to a rogue access point. It had been configured to mimic networks that victim’s devices had previously connected to, since many devices will automatically reconnect to a known network without checking with the user. That’s why we recommend getting a VPN app for your mobile device to protect all your mobile communications. Even if you don’t have it on all the time, using a mobile VPN is a smart way to protect your personal information.
Most VPN services offer both Android and iOS VPN apps, saving you the trouble of configuring your phone’s VPN settings yourself. VPN providers typically allow up to five devices to be connected simultaneously under a single account. Also, while there are free VPN services available, many require that mobile users sign up for a paid subscription.
Not all mobile VPN apps are created equal. In fact, most VPN providers offer different services (and sometimes, different servers) for their mobile offerings than they do for their desktop counterparts. We’re pleased to see that NordVPN and Private Internet Access provide the same excellent selection of servers regardless of platform. These apps received an Editors’ Choice nod both for desktop VPN apps and Android VPN apps.
One feature of note for Android users is that some VPN services also block online ads and trackers. While iPhone owners can use apps like 1Blocker Free at iTunes Store to remove ads and trackers from Safari, ad blockers aren’t available on the Google Play store.
If you’re of the iPhone persuasion, there are a few other caveats to consider for a mobile VPN. Some iPhone VPN apps don’t use OpenVPN, even if the VPN service that made the app supports the protocol. That’s because Apple requires additional vetting if a company wants to include OpenVPN with its app. VPN app developers have slowly started jumping through those extra hoops and are bringing support for protocols such as OpenVPN to iOS.
Thankfully, there’s a workaround for this problem. Instead of using the VPN app from the company from which you’ve purchased a subscription, you can download the standalone OpenVPN app. Open it, and you can enter your subscription information from the VPN company you’ve decided to work with. The OpenVPN app will then connect to the VPN company’s servers using our preferred protocol.
Which VPN Is Right for You?
Computer and software providers work hard to make sure that the devices you buy are safe right out of the box. But they don’t provide everything you’ll need. Antivirus software, for example, consistently outperforms the built-in protections. In the same vein, VPN software lets you use the web and Wi-Fi with confidence that your information will remain secure. It’s critically important and often overlooked.
Even if you don’t use it every moment of every day, a VPN is a fundamental tool that everyone should have at their disposal—like a password manageror an online backup service. A VPN is also a service that will only become more important as our more of our devices become connected. So stay safe, and get a VPN.
