What is OpenVPN? Why do you need OpenVPN on Windows and Linux?

OpenVPN is a free and open-source software that allows users to create a virtual private network (VPN) to secure their Internet connection. By encrypting data and hiding your IP address, OpenVPN helps protect your personal information while accessing the Internet, which is especially important when using public Wi-Fi networks. By installing OpenVPN on Windows and Linux, you will be able to safely access blocked content and protect your privacy from external threats.
