Is full disk encryption (FDE) worth it? A recent study conducted by the Ponemon Institute shows that the expected benefits of FDE exceed cost by a factor ranging from four to 20, based on a reduction in the probability that data will be compromised as the result of the loss or theft of a digital device.
The report, “The TCO for Full Disk Encryption,” was conducted independently by Ponemon and sponsored by WinMagic. The stated purpose of the study was to learn how organizations are deploying software and hardware FDE systems, as well as to determine the total cost of ownership of such deployments across different industries.
