Our Toughest, Fastest,Most Secure Drive Yet. Designed and built to COMPLETELY meet NIST FIPS 140-2 Level 3 requirements (pending 1Q 2019) meaning that the entire device-the hard drive, electronics, external fasteners, even the enclosure itself-are included within this elevated FIPS validation boundary. The tamper resistant enclosure is milled from a solid block of aircraft-grade 6061 aluminum alloy, snap-off uni-directional security fasteners, and a membrane-style keypad. The Aegis Fortress L3 is the perfect combination of software-free operation, advanced read / write speeds, and the highest level of security and durability. Military-Grade 100% Hardware Encryption: Featuring AES-XTS 256-bit hardware encryption, the Aegis Fortress L3 seamlessly encrypts all data as it's being written to the drive on the fly, protecting your data even if the hard drive is extracted from its enclosure.Software-Free Design: The Aegis Fortress L3 is ready to use right out of the box; no software, no drivers, no updates. Completely cross-platform compatible, the L3 excels on any PC, MAC, Linux, or any mass storage compliant system with a powered USB port.Forced Enrollment: Like all Apricorn Secure Drives, the Fortress L3 has no factory-preset default PIN, thus eliminating the common security vulnerability found in other manufacturer's encrypted drives. With Forced Enrollment, the admin is required to establish a sufficiently complex PIN before the device can ever be set up or used.Configurable: Create custom profiles and mass configure multiple Aegis devices at once with Apricorn's Aegis Configurator (sold separately).Onboard Keypad: All PIN entries are performed on the device's keypad making it compatible with systems without keyboards, and shares no critical security parameters with its host computer.Lock-Override Mode: Designated for specific cases in which the drive needs to remain unlocked, e.g., during reboot, passing the drive through a virtual machine, or other similar situations that would normally prompt our drives to automatically lock. When enabled, Lock-Override Mode allows the L3 to remain unlocked through USB port re-enumeration and will not re-lock until USB power is interrupted or the LOCK button is pressed.Two Read-Only Modes: Perfect for accessing data on the drive in a public setting to protect against USB viruses. Particularly important in forensics, Read-Only Mode is ideal for applications that require data to be preserved in its original, unaltered state and can't be overwritten or modified. The Fortress has two read-only modes. The first is set within the Admin mode and can only be enabled or disabled with the Admin PIN. The second read-only mode can be set and disabled by anyone with a valid PIN.Data Recovery PINs: In the case of lost or forgotten User PINs, up to four single-use Data Recovery PINs can be programmed and used to restore access to the data on the drive.Brute Force Protection: After a predetermined number (programmable; up to 20) of consecutive incorrect PIN entry attempts has occurred, the L3 will conclude that it is under Brute Force Attack and will respond by performing a crypto-erase - deleting the encryption key which will render all of the drive's data useless.Wear-Resistant Keypad - Water & Dust Resistant: Designed with protection in mind, the Aegis Fortress L3's keypad is impervious to dust, grit, and water, and the buttons coated with a durable polymer that defends against surface wear, which could tip off a potential hacker to the drive's most frequently used buttons.
