Bitidentify Technology AB is a Swedish company that provides data security solutions through its Hidden Sovereign Technology (HST). HST uses dedicated hardware that is invisible to operating systems to protect systems and data. It features two modes - an open mode where the intranet is invisible and protected, and a secure mode where the internet is disconnected and data transfer is not possible. This separation of intranet and internet into independent memory spaces enhances security by eliminating the risk of wrong connections or data transfers between networks.
