DataLocker Sentry K300 offers affordable military-grade security with 256-bit AES hardware-based encryption in XTS mode that provides always on protection for your data. Unlike software-based encryption, the Sentry K300 cryptochip does not export encryption keys to the host PC, thereby protecting against cold-boot and malware attacks.


DataLocker Sentry K300 is able to be optionally managed by SafeConsole, a secure cloud or on-premises management platform that allows your organization to centrally manage compatible USB storage devices easily and efficiently. SafeConsole license sold separately.

The Sentry K300 is completely cross-platform compatible and OS agnostic. With no software or special drivers required, the K300 works with Windows, Linux, Mac, Android phones and tablets, Chromebooks, and embedded systems – any system that can utilize USB Mass Storage. Since the K300 also has its own power supply, the device can be used as a bootable device running Windows to Go, Ubuntu Linux, or local operating system.


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 K300, it is always protected from unauthorized access.
