With hundreds of laptop computers being lost or stolen every day, one way to keep your files save is to protect them with a Data Key.

The device, which plugs into a USB port, can encrypt and lock data on any laptop, making it impossible to read without a key and password.

A really good security system needs two things to make it effective - a key to lock and unlock the computer and a password to be sure the key user is authorised to have access to the data.

The Data Key, combined with an effective password, en-ables the user to encrypt and decrypt data on the fly.

The computer stores the data in an encoded form and only de-crypts it when the user views a file.

Even if a file is downloaded from the computer, it will be impossible to read without the key and the password.

The Data Key comes with a driver CD and takes minutes to install.

It creates a secure area on the laptop and offers peace of mind to any owner daft enough to leave the computer lying around or unlucky enough to have it stolen.

It can also be used to create a secure area on a network that will disappear when the key is removed from the USB socket.

Plug the key in to find the secure data storage area with Windows Explorer, pull it out and the secure data storage area vanishes.

It is so easy and absolutely brilliant.
