The DTS1 is the embedded industry’s first commercial off-the-shelf (COTS) data-at-rest (DAR) network-attached storage (NAS) solution that supports two layers of full disk encryption (FDE) in a single device. Having received Common Criteria (CC) certification, the hardware and software FDE layers used in the DTS1 are now currently listed on the United States NIAP Product Compliant List, NSA’s CSfC Components List, the International Common Criteria Certified Products List, and the NATO Information Assurance Product Catalogue (NIAPC). Selecting an approved device enables system architects to greatly reduce the time, cost, and program risk associated with developing an approved encryption solution.
