Why Quantum XC?

Quantum Xchange gives commercial enterprises and government agencies the best and last defense to keep data safe--today and in the future.

The world’s volume of data has been growing exponentially year after year, giving cyber criminals a greater opportunity to expose massive volumes of data

Cybercrime costs the U.S. economy $100 billion a year and costs the global economy $450 billion annually


During the First six months of 2017, more than 10M records were compromised or exposed every day
