Regulatory Compliance

DigiSAFE DCM Onyx employs smartcard technology to protect data in external USB hard disk drives. Its usage by enterprises will allow compliance with regulations such as HIPAA, GLB Act, Sarbanes-Oxley Act, EU Data Protection Directive, FISMA and Japan’s Personal Information Protection Act.

Use Cases:

1. Secure portable storage/back-up

DCM Onyx ensures that all the data stored (or backed up) on the hard disk is fully encrypted and safe from the prying eyes. What’s more, the smartcard (containing the encryption key) as well as the correct PIN are both required to unlock the data, giving you the ultimate level of protection, yet ease of use.

2. Booting an operating system from DCM Onyx

An operating system such as Linux can be installed on DCM Onyx to allow the user to carry a “portable OS”. This also means your operating system is fully encrypted. Of course, both the host machine and the operating system must support booting from a USB device in the first place. Approach your OS vendor to advise.
