Yes. Although Netflix is now available almost everywhere, some places – notably the United States – enjoy a much larger catalog of titles than everywhere else. And some people want to access regional catalogs. In theory, all you need do to watch a local version of Netflix from somewhere else is connect to a VPN server in that country. You can sign into any regional Netflix page with any active Netflix account, no matter where that account is registered. The snag is that due to pressure from its content producers, Netflix now tries to ban IP addresses that it knows belongs to VPN and proxy services. Many VPN services have found sneaky ways around this ban, but it is a cat and mouse game. Please see our best Netflix VPNs for a list of services which still work with Netflix (most of the time).
Using a VPN will prevent most kinds of DNS attacks that would redirect you to a phishing page, but a regular old page made to look like a legit one in order to trick you into entering your data can still work. Some VPNs, and most browsers, are pretty good about blocking phishing pages, but this attack still claims too many victims to be ignored. Use common sense and be sure to verify that websites are what they say they are by looking carefully at the URL and always visiting HTTPS sites.
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.
