iTwin is a pair of USB keys that turns your computer into a server and VPN, letting you access sensitive data securely from a remote machine. Its end-to-end encryption is much more secure than a cloud solution, and $99 is a great price.

iTwin is a two-piece USB dongle that lets you easily and securely access documents between two remote computers with no storage cap--making it a very good Dropbox alternative.

USB-stick shaped device offers a super handy way to securely share files using hardware encryption, and with little fuss.

iTwin is one of those devices that does one thing, and does it well. It's a good way to access files remotely and securely, especially if you don't want to throw them up into the cloud.

For files too sensitive to be stored in the cloud, transferred by email or backed up on USB flash drives, the iTwin offers a handy and easy-to-use secured wireless bridge between two computers.

It connects two PCs over the web securely, irrespective of their position in the real, living, breathing world. However, the fairly high price and functional limitations of the technology limit its appeal. If security is a key concern, the iTwin has what you need.

Even with some of the iTwin's disadvantages the device may be the most cost-effective way to access all of your data on another computer. Its plug-and-play simplicity and standout security features make the iTwin pretty revolutionary.

iTwin has secure end to end encryption and no other fees once the device has been purchased. The only downfall with the iTwin is that you can only connect two online computers at one time and not more.
