As the only integrated solution for encryption and backup, Knox makes securing your files easier than ever. Create as many encrypted vaults as you want, each with separate passwords. Then schedule automatic backups. You can even reformat USB sticks and external drives as encrypted Knox vaults moving files between Macs has never been so simple and secure. Knox uses the Mac OS X encrypted disk images feature, the technology behind FileVault, to protect your data. This means that your vaults are encrypted by the U.S. Government's new Advanced Encryption Standard (AES) with 256-bit or 128-bit key length. The AES algorithm is secure, but don't take our word for it: even the NSA has found its strength to be sufficient for protecting classified national security information. The implication? Your data will be safe whether it's a rogue kid or a rogue nation going after it. And because the encrypted disk images are supported as standard in Mac OS X, Knox vaults--including whole disks encrypted with Knox--can be opened even without Knox installed.
