Which technology provides encryption around data sent across a network?

The technology that provides encryption around data sent across a network is SSH, or Secure Shell. SSH is a cryptographic network protocol that enables secure communication over an unsecured network by providing a secure channel in a client-server architecture. When using SSH, all data transmitted between the client and server is encrypted, which protects it from eavesdropping, connection hijacking, and other attacks.

SSH not only secures remote logins but can also secure file transfers and other types of communication, making it a versatile tool for securing data over a network. Its use of strong encryption algorithms ensures that the data remains confidential and integral, preserving both privacy and security.

In contrast, VPNs also encrypt data, but they serve a broader purpose by creating a secure tunnel for all network traffic, not just specific protocols or sessions. Proxy servers generally do not provide encryption but act as intermediaries between a user and the internet, while Remote Desktop is a way to connect to a desktop or server remotely and may include encryption, it is not primarily a protocol for general data transmission like SSH.
