SSVPN - Secure Web Surfing is a free utility and tools application available for iPhone users. Developed by Yiwu Madan Network Technology Co. Ltd., this program aims to provide users with a secure web experience through the use of SS and VPN servers.

The application offers two main features: SS (Shadowsocks) and VPN (Virtual Private Network). With SS, users can directly connect to the internet for some sites, while connecting to other sites through the provided SS servers. This allows for a more seamless and efficient browsing experience.
