We can go into the greater explanation about these three metrics but what matters to you, is important. We assume that most of you are content consumers and are more inclined towards reading the news, using BitTorrent, streaming movies, or listening to music to pull down the data more or less continuously. With that in mind, we’re anchoring on download speeds as the dominant benchmark. So, when we say “fastest VPN,”, we mean, those that have the least impact on download speeds. In case it doesn’t apply to you, we’ve also the top performers in the other two categories.
PPTP - PPTP has been around since the days of Windows 95. The main selling point of PPTP is that it can be simply setup on every major OS. In short, PPTP tunnels a point-to-point connection over the GRE protocol. Unfortunately, the security of the PPTP protocol has been called into question in recent years. It is still strong, but not the most secure.
The first step to security is usually a firewall between the client and the host server, requiring the remote user to establish an authenticated connection with the firewall. Encryption is also an important component of a secure VPN. Encryption works by having all data sent from one computer encrypted in such a way that only the computer it is sending to can decrypt the data.
Finally, read the fine print to see if they restrict any protocols or services you wish to use the service for. If you want to use the service for file sharing, read the fine print to ensure your file sharing service isn’t blocked. Again, while it was typical to see VPN providers restrict services back in the day (in an effort to cut down on bandwidth and computing overhead) it’s more common today to find VPNs with an anything-goes policy.
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.
