iTwin first made a name for itself in 2009 when it released its dongle, which connects PCs to each other via USB. Now iTwin presents to us its all new SecureBox, a more secure form of cloud storage. The only requirements are an iTwin dongle and the SecureBox software. Once the two halves of the iTwin are set up, it syncs itself with Dropbox and generates a unique security code, which is stored on both halves of the dongle. Then, SecureBox pops up and lets you transfer your files back and forth from your PC or Mac to your encrypted cloud and encrypts your data before storing it in the Dropbox cloud. You will only need to connect the two halves of the iTwin during the setup procedure; once this is done, each device will be able to encrypt and upload your files to the Dropbox cloud. This system is virtually flawless aside from the fact that the iTwin dongle can be physically separated. Ideally, only one of the USB devices will ever be accessible to remove the risk of someone being able to use the second one to access your personal information.
