Nearly 4 billion data records were stolen in 2016. Each one cost the record holder around $158. Today, files are encrypted while in transit and at rest, but decrypted while in use. This allows hackers to view or steal unencrypted files. Cyber-attacks will continue to exploit this and today’s technologies will not be able to keep pace.
For example, many years from now, a fault-tolerant, universal quantum computer with millions of qubits could quickly sift through the probabilities and decrypt even the strongest common encryption, rendering this foundational security methodology obsolete.
