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.
My rule of thumb is to use a domestic VPN and connect to servers as close to my location as possible. That said, I have had good nights and bad nights getting online. In my recent trip, I found most hotels' networks to become unusable after about 9pm. My theory is that many of the guests were watching Netflix at that time, completely clogging the hotels' pipes.
ExpressVPN scored well in our recent round of testing in terms of speed – we recorded around 8.5MB/s (68Mbit/s) via both FTP and HTTP in the UK, while Dutch endpoints gave us 6.3MB/s (50.4Mbit/s) via FTP and 7MB/s (56Mbit/s) via HTTP, more than enough for general browsing, streaming and downloading. US connection speeds, as you’d expect, were rather slower at 2.5MB/s (20Mbit/s) via FTP and a good 3.2MB/s (25.6Mbit/s) over HTTP.
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.
