Secure portable storage

The Apricorn Aegis Secure Key is a 240GB USB 3.0 flash drive built for users who must protect sensitive data on the move. Hardware-based 256-bit AES XTS encryption secures every file without relying on host software. A built-in alphanumeric keypad lets you unlock the drive with a 7-16 digit PIN before insertion. It suits professionals in government, finance or any regulated sector needing validated assurance.

Keypad and certifications

The integrated keypad means the drive works on any USB-enabled host — Windows, Mac, Linux or embedded systems — with no drivers or admin rights required. FIPS 140-2 Level 3 validation confirms the cryptographic module meets stringent government standards. IP58 certification adds dust and water resistance, while epoxy filling makes the internals tamper-evident and tamper-resistant. Admin and User PINs can be set independently for shared deployments.

Hardware encryption standard

The defining specification is 256-bit AES XTS hardware encryption validated to FIPS 140-2 Level 3. This certification decides whether the drive satisfies compliance mandates for data at rest. Buyers who need software-managed encryption or a non-validated device should look elsewhere.

Questions about this item

How long does the epoxy-filled internal compartment protect the flash memory before it needs replacement?

The epoxy-filled compartment encases all electronic components for tamper resistance and does not require periodic replacement; the drive has no user-serviceable parts.

What capacity limit appears first during continuous large-file transfers on this 240GB drive?

The 240GB total capacity is the first limit; once filled, no further data can be written until space is freed.

How much heat or power does the aluminum housing generate during all-day encryption workloads?

The IP58-rated aluminum housing dissipates heat passively with no active cooling; power draw follows the USB 3.0 specification and produces minimal warmth.
