Here's a nifty gadget that might just pump up your security without draining your budget - The EVERYTHING AnyWare /ASAS(R) system improves productivity by enabling anyone to access their data and applications and do their work anywhere at any time. The brainchild of Authenex and ASIERUS, Inc., the new patent pending suite of products and services that promises to increase business agility and continuity while reducing overall IT cost. Here's the company line on how it works:

"A user plugs his A-Key(R) token into the USB port of any computer with an internet connection and enters his PIN. The A-Key(R) token's auto launch feature automatically launches a Web browser, which takes him to the ASIERUS, Inc.(TM) Web Portal. A secure tunnel is authenticated by a client-side certificate that ACert(TM) software (residing securely on the A-Key(R) token) issues and is then encrypted by the VPN end point certificate.
The token guarantees the identity of the user by generating a unique One Time Password (OTP) six-digit authentication number and automatically appends it to his PIN, then logs the user onto the network. The user can then access his company's virtual office and download his data onto the secure flash memory on his token and take
it anywhere, knowing that his data is totally secure from loss and theft. Whether working from a remote session or from his flash drive offline, the data is never on the computer being used."
