There are USB flash drives and then there is the Aegis Secure Key.
First off, this thing is government rated on a variety of levels. Not only can it withstand dust and water thanks to its IP57 certification, but it has been tested and validated by the Federal Information Processing Standards (FIPS) to meet the U.S. government standards for information technology and computer security, otherwise known as FIPS 140-2 Level 3.
But a bunch of ratings and specs aren’t the complete story. As you’ve probably deduced from the above pic, to access this drive’s contents you’ll need to punch in a 7-15 digit PIN before connecting to the USB port on your computer. This prevents the connected computer from key logging your password and compromising the flash drive’s contents. In the event you forget your PIN an admin PIN can reset it, or you can completely wipe the drive and start from fresh. And if someone does try to try to force their way in, it will delete the Aegis Secure Key’s contents after 10 incorrect PIN entries.
Furthering security is built-in 256-bit AES CBC (Cipher-Block Chained) hardware encryption and an auto lock feature that secures the drive when’s it removed from the USB host.
The Aegis Secure Key is available in 4GB, 8GB, 16GB, and 32GB capacities with a starting price of $65.
