SED (self-encrypting drive) would be the most acceptable option for an organization with a low tolerance for user inconvenience that wants to protect laptop hard drives against loss or data theft. SEDs are hardware-based encryption devices that automatically encrypt data on a hard drive without requiring any additional input or configuration from the user. This means that the user does not have to perform any additional steps to encrypt their data, which can help to prevent data loss or theft. By contrast, other options like HSM (hardware security module), DLP (data loss prevention), and TPM (trusted platform module) may require more user involvement and may not be as convenient for users.
