The basic premise of iTwin is a pair of USB devices, one of which goes in your work desktop, the other in your home (or laptop) computer. Files can then be copied securely to and from the work computer across the internet to the laptop.
The devices are cryptographically paired together to ensure the security of the connection and the creators seem to have solutions for most of the issues that might arise, such as dynamic IPs or theft.
The brilliance of iTwin is that it offers a personal cloud solution where the data is completely under your control but not actually in your possession. No risk of theft, loss or nosey border guards rifling through your files.
Works with both Windows PCs and Mac – available now for $99.
