Secure Socket Funneling

Secure Socket Funneling (SSF) is a tool designed to forward data from multiple sockets securely. It supports local and remote TCP and UDP port forwarding, enabling users to tunnel traffic efficiently through a single TLS-encrypted connection. This makes it useful for scenarios requiring secure data transfer over untrusted networks, such as remote access or bypassing network restrictions.

The Windows binaries package provides both 32-bit and 64-bit versions, catering to different system architectures. SSF also supports local and remote SOCKS servers, shell access through sockets, and a native relay protocol, enhancing its versatility for tunneling applications.

With TLS connections using the strongest cipher-suites, SSF ensures high security for forwarded traffic. The installed size is 30.11 MB, and it was last updated on 2025-Dec-09.

SSF forwards data from multiple TCP or UDP sockets through a single secure TLS link to a remote computer. It utilizes native relay protocol for efficient tunneling and supports features like local/remote TCP/UDP port forwarding, SOCKS servers, and shell access over sockets. Connections are secured with TLS using the strongest available cipher-suites.
