    The Apricorn Aegis Secure Key 3NX (ASK3-NX-4GB) is a 4GB USB flash drive with onboard keypad authentication and 256-bit AES XTS hardware encryption, suited to people who need to carry small amounts of sensitive data without installing security software.

    Recommended For

    • People who carry a small set of sensitive work documents—such as customer records or confidential files—and want the drive itself to require a PIN before access.
    • Mobile workers who need to carry files between Windows, Mac, Linux, or other USB mass-storage devices without installing encryption software on each host.
    • Traveling professionals who want an offline copy of a few important files when cloud access is unavailable, with keypad authentication and a dust- and water-resistant enclosure.
    • Organizations issuing small, managed sets of secure USB drives to staff who handle sensitive data and need hardware-based PIN access rather than host-installed security software.
