2) Kingston IronKey Keypad 200 Series
The Kingston IronKey Keypad 200 Series is a noteworthy addition to Kingston's extensive lineup of flash drives. Kingston is a renowned name in the industry, known for producing high-quality storage solutions, and this hardware encryption flash drive is no exception. Launched just last year, it stands out with its OS-independent hardware encryption and offers two interface options: USB-A and USB Type-C, both equipped with a keypad for secure PIN access.
Security is paramount with the Kingston IronKey Keypad 200 Series. It takes data encryption to the next level, surpassing even the Omni DataSafe. This device employs XTS-AES 256-bit encryption and boasts pending FIPS 140-3 Level 3 certification for military-grade security. For those attempting to tamper with the flash drive and access its components, the circuit board is safeguarded with a special epoxy layer, making it virtually impossible to remove components without causing irreparable damage.
The XTS-AES 256-bit encryption is part of a comprehensive security package, combining 256 and 128-bit encryption for a total of 384 bits of encryption key strength.
What sets the IronKey Keypad 200 Series apart is its dual-access functionality. Admin can set up global or session read-only options, along with multi-PIN access for both administrators and users. The Admin mode provides two levels of access, including Read-Only (or Write-Protect) modes. The global mode can be configured by the Admin, while the session-only mode can be set by the user. Read-only modes serve as an extra layer of protection against malware when using the drive on untrusted systems.
Storage options for the Kingston IronKey Keypad 200 Series range from 8GB to 256GB, ensuring there's a suitable capacity for every user. It leverages USB 3.2 Gen1 for speedy data transfer. Additionally, users have the choice between USB Type-A and Type-C interfaces.
When it comes to pricing, it's worth noting that the Kingston IronKey Keypad 200 Series, starting at 8GB, is priced at $74.99. While it offers superior security features compared to the Omni DataSafe, it is positioned at a slightly higher price point.
3) Aegis Secure Key 3Z
Consider the Aegis Secure Key 3Z if you require the most durable encrypted flash drive capable of withstanding rigorous tasks.

Additionally, it holds a NATO restricted rating and boasts an IP67 rating for robustness. Notably, the Aegis Secure Key 3Z is designed and assembled in California, USA, ensuring quality and reliability.
At its core, the Aegis Secure Key 3Z prioritizes security and durability. It offers a 100% hardware-based 256-bit AES XTS encrypted USB key with keypad PIN authentication. Meeting the FIPS 140-2 Level 3 standard, it aligns with the stringent U.S. government requirements for information technology and computer security.
Similar to the Kingston IronKey, this device provides Admin and User access modes, complete with independent admin and user PINs. Furthermore, you have the flexibility to select the number of allowed invalid PIN attempts, ranging from 4 to 20, before triggering a crypto-erase.
One notable advantage of the Aegis Secure Key 3Z is its immunity to software or hardware-based keyloggers and software-based brute force attacks when the PIN is entered using the host computer's keyboard. However, in the face of a physical brute force attack, a programmable "brute force hack defense mechanism" safeguards your data.
Another noteworthy feature is the option to set an unattended auto-lock. Aegis Secure USB drives will automatically lock upon disconnection from a computer USB port or if the power supply to the port is interrupted. Additionally, they can auto-lock after a predefined period of inactivity.
For enhanced data security, the Aegis Secure Key 3Z allows you to set a self-destruct PIN. When programmed and activated, this feature initiates a Crypto-Erase, essentially transforming the device into a new access PIN. This serves as the last line of defense when the physical security of the device is compromised.
Storage options for the Aegis Secure Key 3Z include capacities of 16GB, 32GB, 64GB, and 128GB, with the 16GB version priced at $191.95.
