VPN performance is affected by such a wide range of factors that it’s not possible to produce conclusive test results. The speed of your own internet connection and user load on your selected VPN endpoint server, as well as the server you’re connecting to beyond that all make a difference. Due to the sheer number of frequently-rotated servers provided by most VPN services, comprehensive testing isn’t possible.
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.
TrackStop – Ads are basically advanced tracking to record your browsing, so you can be hit with targeted ads based on your online activity. To protect users against this threat, Perfect Privacy developed TrackStop, which is a powerful filter that blocks advertising, tracking, and malicious domains at the VPN server level. It ranked the best among different VPN ad blockers I tested.

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.


We've knocked CyberGhost down a peg from last year's standings because the service's network performance wasn't as great this time around in our tests. Yet it has a feature-loaded, user-friendly interface, with convenient buttons in the Windows client software for streaming media, torrenting files, protecting your Wi-Fi transmissions and evading censorship. (The Mac desktop software has fewer features.)
You'd be a fool to go with this company. They're based in China and China has already been found to be putting backdoors in routers made there etc. If PureVPN had been any less ethical than their pathetic show of it they have now, they could have kept my money and I would have had nothing I could have done about it. Can't go over to China and kick some idiots butt, unfortunately, so you'd be out that money.
L2TP/IPsec (Layer 2 Tunneling Protocol). This is a combination of PPTP and Cisco’s L2F protocol. The concept of this protocol is sound — it uses keys to establish a secure connection on each end of your data tunnel — but the execution isn’t very safe. The addition of the IPsec protocol improves security a bit, but there are reports of NSA’s alleged ability to break this protocol and see what’s being transmitted. No matter if those are actually true, the fact that there’s a debate at all is perhaps enough to avoid this as well.
