Google is full of articles claiming that a VPN will prevent ISPs from gathering metadata, but unfortunately that is not true. A VPN hides the contents of your internet traffic and your location from the outside world, but you still have to rely on your ISP’s network to get there. Strictly speaking a VPN cannot prevent an ISP from logging your location, device details, and traffic volume.
To be fair, not all pay VPN services are legitimate, either. It's important to be careful who you choose. Over on ZDNet's sister site, CNET, I've put together an always up-to-date directory of quality VPN providers. To be fair, some are better than others (and that's reflected in their ratings). But all are legitimate companies that provide quality service.
To ensure that the results we received for both WebRTC and DNS leak tests were accurate, we decided to conduct a complete privacy analysis. We used the famous IPLeak.net for the process. Fortunately, there were no gaps found in this test too. The default IPv4 address is of a UK location. Even the DNS address gives no indications to our original location. This indicates strong privacy and anonymity!
Chromecast and other streaming protocols send data over your local network, but that's a problem when you're using a VPN. Those devices are looking for streaming data from phones and computers on the same network, not from a distant VPN server. Likewise, smart home devices may be gathering lots of data about you and your home that you'd rather not have intercepted. Unfortunately, these devices simply cannot run VPNs. The solution for both problems is to move the security up a level by installing a VPN on your router. This encrypts data as it leaves your safe home network for the wild web. Information sent within your network will be available, and any smart devices connected to your network will enjoy a secured connection.
The only downsides to Private Internet Access are that you can't select your own username — you've got to stick with an assigned random ID — and that you've occasionally got to reinstall a balky driver in Windows. (There's a button to do this.) Selecting Private Internet Access as our VPN service of choice was almost a no-brainer, but because it's based in the U.S., anyone wary of the FBI may want to consider another service.
The heart of the security a VPN provides is its encryption keys—the unique secret that all your VPN devices share. If the keys are too short, VPN data is susceptible to brute-force cracking. You can often choose the key length to use in your VPN implementation. The longer you make keys, the harder they are to break, but the trade-off is that longer keys also require more processor power for encryption and might slow packet throughput. The minimum recommended key length now is 64 bits (128 bits, if possible) for the symmetric ciphers that encrypt the data and 2048 bits for public key cryptography such as RSA. Modern desktop computers can often crack 40-bit and shorter keys, such as those that DES uses.
CyberGhost operates an ample network of more than 1,200 servers, including 20 in Australia and more than 200 in the US. It has a strong focus on unblocking streaming services like Netflix and Amazon Prime Video. It’s also popular with torrenters and has a dedicated “Torrent Anonymously” option within its apps. Plus, speeds are excellent, making it a great all-rounder. CyberGhost doesn’t log user activity or record IP addresses. Apps are available for Windows, MacOS, iOS, and Android.
With a name like TorGuard, the software better offer strong protection. The software’s hallmarks lie in its ability to connect to a melange of services for different activities, with four different packages available based on various needs. The VPN service will run you $10 each month, but there’s a cheaper proxy service if all you need to do is hide your IP address from the world.
Like most VPN services, the program will prevent websites from viewing your personal IP address, thus preventing others from identifying you or your geographic location. From offshore email to unlimited server switching between over 3,000 servers across the globe, TorGuard offers some pretty impressive scaling. Skilled geeks and professionals alike should take a look at the service, along with the discount bundles that come packaged with hardware.
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.
HotSpot Shield is a product that has had some ups and downs in terms of our editorial coverage. Back in 2016, they picked up some very positive coverage based on founder David Gorodyansky comments about protecting user privacy. Then, in 2017, a privacy group accused the company of spying on user traffic, an accusation the company flatly denies. Finally, just this year, ZDNet uncovered a flaw in the company's software that exposed users. Fortunately, that was fixed immediately.
