The VPN is a network tool that provides users with several features to enhance their online privacy and security. One of its modes is the sub-application proxy mode, which allows users to select specific applications to route through the VPN while leaving others to use the regular internet connection. This feature is useful for users who want to protect their sensitive data while using specific applications without slowing down their entire internet connection. Additionally, the VPN has an automatic test for successful node connection that ensures users are always connected to the fastest and most reliable server available. This feature is particularly useful for users who want to ensure that their internet connection is always fast and stable.<br/><br/>Another feature of the VPN is the node batch test real connection speed, which allows users to test the speed of multiple servers at once. This feature is useful for users who want to find the fastest server available for their location. By testing the speed of multiple servers, users can select the one that offers the best performance and ensure that their internet connection is always fast and reliable. The VPN also has built-in massive global free servers that users can connect to for free. These servers are located in different countries around the world and offer users the ability to bypass internet censorship and access content that may be restricted in their location.<br/><br/>Overall, the VPN offers several features that enhance online privacy and security while ensuring that users have a fast and reliable internet connection.
