Encryption appliances sit inline on a network and use specially designed electronics to encrypt data at line speeds, essentially eliminating the performance penalty imposed by encryption software running on a general server. While software-based encryption is typically handled as a specific event or process (e.g., encrypting data during a backup process), appliance-based encryption normally can handle any quantity of data in flight.
