And even if you don’t use VPNs and just want to learn about them, this is a good starting point as any. We’ll even throw in a quick VPN definition before we begin too.
A VPN client is the Virtual Private Network software that’s installed on your device to establish a connection between it and the VPN server, and offer access to VPN services.
Most of the popular platforms like Windows, macOS, iOS, and Android come with pre-installed VPN client software, but you can also install third-party clients to enjoy a better user interface and more features.
Generally, there are two types of VPN clients:
These are pre-installed or pre-configured VPN clients that are available in some operating systems like Windows, macOS, iOS, Android, and Linux distros like Ubuntu.
They could further be divided into two categories:
It’s pretty simple – in order to establish a VPN connection to a VPN server, and also ensure the encrypted VPN tunnel is configured between you and the server, your device needs a VPN client since it’s responsible for handling all of that.
Before a VPN client and server can even communicate, they authenticate each other through data packets. This mutual authentication process is crucial because it makes sure the client is communicating with the right server and vice versa.
Afterwards, the VPN software encrypts your data before sending it over to the VPN server. Once the server receives the info, it decrypts it, and forwards your traffic to the web. When the VPN server receives the Internet data you requested (website access, for example), it encrypts it, and sends it back to the VPN client on your device, who then proceeds to decrypt the information for you.
Thanks to the encryption process, your ISP (or any government surveillance agency or hackers, for that matter) can’t keep tabs on your connection requests and online traffic to see what you’re doing on the web. Only the VPN client and the VPN server can encrypt and decrypt the data.
Both built-in and third-party VPN clients are available on the most popular operating systems and devices. As a general rule of thumb, VPN client software works on:
However, not all operating systems and devices have native support for VPN clients. For example, smart TVs that don’t run an Android or Fire OS can’t have VPN applications installed on them. The same goes for gaming consoles like Xbox or PlayStation, or mobile phones like BlackBerry that run the BlackBerry 10 OS.
In those situations, manual VPN connections can still be established on some devices by taking advantage of the VPN protocol support and using configuration files offered by VPN providers.
If none of that is possible, though, your only option is to either share your computer or laptop web connection with the device in question (which can be quite inconvenient) or set up a VPN on your router.
The router option is usually the best one since, if you do that, any device that accesses the web through your router will use a VPN connection – yes, even IoT devices like smart thermostats or smart locks.
Overall, here are the things you should be on the lookout for when checking out VPN providers and their clients:
