Everything you do on the Internet has to pass through your own ISP before reaching the destination. So, when you request Google, for example, the information is sent, unencrypted, to your ISP and then passes through some other channels before reaching the server that holds Google’s website. Basically, VPN services privatize information that can be read by ISPs or any other agency that inspects your traffic.
Update: We’ve received some feedback that 10Mbps is too slow to get good test results. We would argue that 10Mbps is quite average for home internet across the world, and we run tests for average people. While our tests might not be a good indication of speed if you’re paying for a 50 Mbps or 100 Mbps connection, the results are varied enough to get a statistically significant indication of overall performance. Furthermore, all the VPNs on the list officially offer unlimited bandwidth, so if you happen to be on an uncongested nearby server, chances are you’ll still be able to max out your available bandwidth. Finally, there is no point in having a fast VPN if it is unstable, doesn’t protect your privacy, doesn’t unblock the content you want, or doesn’t have a good range of servers to connect to. We excluded providers like TotalVPN which were very fast but had awful customer service, for example.
This is important to understand. Consumer VPN services protect your transmission from your location to their location, not from your location all the way to the destination application you're using. If you think about it, this makes sense: A consumer VPN service is operated by a completely different company than, for example, Facebook or your bank.
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.
Though PIA doesn’t list its leadership on its website, that information isn’t hard to find. The founder, Andrew Lee, has been interviewed by Ars Technica; the CEO, Ted Kim, is also on the record; and privacy activist and Pirate Party founder Rick Falkvinge is listed as Head of Privacy on the company’s blog. PIA can also point to court records showing that when approached by law enforcement for detailed records, the company had nothing to provide. PIA boasts a huge network of servers and locations around the world, and though the PIA app isn’t as polished as those of some competitors, it is easy to use. Like our top pick, IVPN, its iOS app also added OpenVPN support in mid-2018. But in our speed tests, PIA was just okay, not great. When we averaged and ranked all of our speed tests, PIA came in fifth, behind our top picks as well as OVPN and ExpressVPN.
Sadly, I engaged PIA, the number one rated and paid a "great price" for a 3 year service only to findout that dur to a recent SMTP abuses they no longer can be used when using Microsoft servers. So, all of my outbound email is rejected from Microsoft Servers due to this policy. In itself, fine, but as I enrolled in this service and while setting up the servie at no time was this mentioned nor, prior to a May 15 issue, was this a problem.
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.
