The Secure Shell (SSH) protocol primarily provides secure remote access to network devices. This means that it allows users to connect to and manage network devices, such as servers and routers, over an unsecured network. SSH encrypts the data transmitted between the client and server, ensuring that sensitive information, such as login credentials and commands, cannot be intercepted by malicious actors. This secure communication is essential for systems administration and for accessing devices in a secure manner, particularly over the internet.

In contrast, the other options do not accurately describe the primary purpose of SSH. Unencrypted file transfers do not reflect the capabilities of SSH, which actually offers secure file transfer mechanisms as part of its functionality (through protocols like SFTP or SCP). Public communication does not align with the nature of SSH, as it specifically focuses on secure, private communications rather than open or public exchanges. Lastly, while high-speed internet connections may be required for successful SSH sessions, they are not a feature provided by the SSH protocol itself; rather, SSH's main function revolves around secure access and not the speed of connectivity.
