Stunnel is a powerful and flexible open-source software that provides SSL/TLS encryption for network communications. It acts as a proxy designed to secure connections between clients and servers, effectively wrapping unencrypted data streams in a secure layer. By using Stunnel, organizations can enhance the security of their existing applications without altering their core functionalities.

Stunnel supports a wide range of protocols, making it a versatile tool for encrypting various types of network traffic. It is commonly employed to secure email communication protocols like POP3, IMAP, and SMTP, as well as other services such as web servers and remote access tools. The software operates by creating encrypted tunnels between clients and servers, ensuring that sensitive information remains protected from eavesdroppers and unauthorized access.
