Hardware-encrypted USB drive for secure data

The Apricorn Aegis Secure Key 3NX is a 4GB USB 3.0 flash drive that uses 256-bit AES XTS hardware encryption to protect stored files. It is built for professionals and organisations that must keep sensitive data confidential while moving it between systems. The drive operates without any host software, so it works on any device that supports USB mass storage.

FIPS 140-2 Level 3 validated encryption

This model carries FIPS 140-2 Level 3 validation, confirming that its cryptographic module meets stringent government-grade physical and logical security requirements. The 256-bit AES XTS engine is embedded in the controller and cannot be disabled or bypassed. All encryption and decryption occurs inside the drive, leaving no trace on the host computer.

Keypad unlock with IP67 ruggedness

A built-in alphanumeric keypad lets the user enter a PIN before the drive becomes visible to the operating system, eliminating software installation and driver issues. The enclosure is IP67 certified, meaning it resists dust ingress and temporary immersion in water. Users should remember that a forgotten PIN cannot be recovered and will render the data permanently inaccessible.

Questions about this item

What does the 256-bit AES XTS encryption mean for everyday use?

The drive encrypts every file on the hardware itself, so data stays protected without installing any software on the host computer.

How does the USB 3.1 Gen 1 interface affect transfer speed?

It operates at USB 3.0 rates, so the drive will hit the practical ceiling of that standard rather than any faster spec.

What does the IP67 rating tell me about physical durability?

The housing is dust-tight and can survive immersion in water up to one metre deep for thirty minutes.
