Delivering all of the same next level security features as our Aegis line of secure drives, in an extremely rugged enclosure, and with a new, ultra fast encryption chipset, the L3 is the fastest, most robust, highest capacity drive we've ever made. Tough on the outside, the Fortress L3 is designed to meet NIST's highest level of FIPS validation attainable for portable devices: 140-2 level 3. Small enough to go in a pocket or briefcase, large enough to carry up to 20TB of data, the Fortress L3 allows you to securely and easily carry large amounts of sensitive data everywhere you go. Available in a wide variety of storage capacities in both HDD and high speed SSD models. The Aegis Fortress is Software-Free, 100% hardware-based 256-bit AES XTS encrypted, and onboard keypad PIN authenticated with ultra-fast USB 3.1 (3.0) data transfer speeds. All Data is encrypted on the fly and all PINs and Data remain encrypted while the drive is at rest. Completely cross-platform compatible and OS agnostic; the Aegis Fortress thrives with Windows, Linux, Mac, Android, Symbian and Chrome. It also thrives where software-authenticated encrypted devices can't function, such as embedded systems and equipment in possession of a powered USB port and storage file system but no keyboard.
