The data security filter allows you to select different modes of separation for individual data zones. It provides the user with the function of a data diode, which is based on a HW solution, as well as the function of a configurable data filter that can enable or disable the transmission of various data formats from one data zone to another. The data filter’s software solution makes it possible to customize the data filter according to the specific situation and the user’s needs.
