    Apricorn Aegis Fortress A25-3PL256-S4000F 4TB External Solid State Drive

    • Tested and Validated by the National Institute of Standards and Technology (NIST), the Aegis Fortress is validated to meet the Federal Information Processing Standards (FIPS) 140-2 Level 2 specification.
    • Featuring 256-bit AES-XTS hardware encryption, the Aegis Fortress seamlessly encrypts all data on the drive in real-time, keeping your data safe even if the solid state drive is removed from its enclosure.
    • With an easy-to-use keypad design and software free setup, it enables you to access the drive with your own unique PIN. The embedded keypad prevents hardware and software key logging attempts to capture your password entered via the host system.
    • The encryption chip and circuitry are completely protected by a super tough epoxy compound, which is virtually impossible to remove without causing permanent damage to the electronics.
    🔥Don't forget your OS, we have Windows 11 OEM, Download and USB versions available
