DataLocker Sentry ONE offers affordable military-grade security with AES 256-bit hardware-based encryption in XTS mode that provides always on protection for your data. Unlike software-based encryption, the Sentry ONE encrypted flash drive’s cryptochip does not export encryption keys to the host PC, thereby protecting against cold-boot and malware attacks.


  • Tamper evident seal for physical security
  • The entire device is FIPS 140-2 Level 3* certified, not just the controller
  • Unlock in Read Only Mode to prevent files from being modified or infected with malware
  • Configure inactivity AutoLock to prevent unwanted access
  • Initiate a reset sequence after 10 consecutive incorrect password attempts and return to factory settings



DataLocker Sentry ONE is available in standard or managed versions.  The managed version requires a device license and can be managed by either SafeConsole or IronKey EMS. Both SafeConsole and IronKey EMS are secure cloud or on-premises management platforms that allows your organization to centrally manage compatible USB storage devices securely, easily and efficiently.


Every year, 20 million unprotected USB drives go missing. If the data stored on those drives ends up in the wrong hands, you can lose public trust, put citizens at risk and suddenly find yourself in the middle of a PR scandal. Secure USB flash drives are an essential component of a comprehensive data loss prevention (DLP) strategy. The security must be implemented in the hardware in order to combat the evolving threat landscape. With your data stored on the hardware-encrypted Sentry ONE, it is always protected from unauthorized access.
