Shattered storage device with exposed files and a broken padlock, showing data left readable after a password is guessed

Unencrypted Data at Rest

Problem

Files copied to a conventional USB drive are stored in plain form, readable on any computer the drive is plugged into.

Password Guessing

Problem

A drive that allows unlimited password attempts can eventually be opened by repeated guessing.

Lost or Stolen Drives

Problem

Small drives travel in pockets and bags and go missing, taking whatever is stored on them.

Sensitive and Everyday Files Mixed Together

Problem

A single volume gives confidential material and everyday files the same level of access.

Encryption That Depends on the Host

Problem

Encryption that has to be installed on the computer, often with administrator rights, is unavailable on locked-down or shared machines.

Key Advantages

Why X-PHY Cipher Vault?

Encryption that lives on the drive

Hardware-Based Encryption Engine

Encryption is performed by a hardware engine on the drive itself rather than by software running on the host computer.

Password Authentication

Encrypted data can only be accessible after password authentication. Set a private password of up to 16 characters, with a password hint function available as a reminder.

Anti-Brute Force Protection

A configurable Number of Attempts (NOA) guards against brute-force attacks. Six chances are given to enter the correct password, with a warning before the last retry; if all attempts fail, secured data is formatted and the password removed. Data becomes permanently invalid when the password is reset or the maximum NOA is passed.

Separate Space Partition

Password protection applies to the secure partition only. The public partition is available to all users to read and write data, and the size of the secured and non-secured areas can be customised.

Nothing to Install

No software or drivers installation required, and guest mode authentication is supported with no administrative privilege required. The interface follows the detected Windows language across English, Japanese and Chinese (Simplified/Traditional).

Authentication Workflow

How X-PHY Cipher Vault Works

Four steps from first use to protected storage. The full workflow is set out below.

01

Insert the Drive
Connect Cipher Vault to a USB 1.1, 2.0 or 3.0 port. It draws 4.5–5.5V from the port, so no external power is needed.
02

Open Cipher Vault
Run the Cipher Vault security application, which is stored in the public area of the drive.
03

Set Up Your Space
Create your password and set how much of the capacity belongs to the secure partition.
04

Authenticate to Access
Encrypted data is accessible only after password authentication, each time you use the secure partition.
