A VPN client is software that runs on your device in order to securely connect it to a VPN server. All major platforms (Windows, macOS, Android, iOS, and Linux) come with a built-in VPN client that can be configured manually, although OpenVPN always requires a third party client to be installed. Most VPN services now offer custom clients and apps, which are the easiest way to use their service as they come pre-configured with all the correct settings. They also typically offer a range of funky and useful features that are not available by simply manually configuring the built-in VPN client. To clear up any confusion, a ''VPN client'' and a ''VPN app'' are exactly the same thing. Traditionally, the word client is used for desktop software and the word app for mobile software, but it is becoming increasingly common to talk about VPN apps on the desktop. The terms are interchangeable.
One of the biggest things that can put people off the idea of using a VPN is that they slow down your internet. This is mainly because you are adding an extra leg to the journey your data must take to reach its destination (via the VPN server). These days good VPN services are very fast and if you connect to a server near to you, you will often get 90% or more of your raw internet connection speed.

In short, it's time to start thinking about protecting your personal information. That's where virtual private networks, or VPNs, come in. These services use simple software to protect your internet connection, and they give you greater control over how you appear online, too. While you might never have heard of VPN services, they are valuable tools that you should understand and use. So who needs a VPN? The short answer is that everyone does. Even Mac users can benefit from a VPN.
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.
