IronKey Enterprise S250 and D250 Encrypted USB with Management

IronKey Enterprise S250 and D250 flash drives are designed specifically for enterprise, government and military customers that require exceptional security, performance and manageability from their mobile storage devices. Built from the ground up to be the world’s most secure flash drives, IronKey Enterprise drives meet the stringent Security Level 3 requirements of the FIPS 140-2 standard, are outfitted with strong hardware encryption, and use the algorithm approved by the DOD for storing Top Secret data. A rugged, waterproof* metal chassis helps protect S250 and D250 drives from the elements. Active anti-malware helps prevent USB threats from spreading. And an intuitive user console makes IronKey Enterprise drives as simple as secure allows.
