Unidirectional Network Market Analysis
Unidirectional network devices are commonly used to ensure information security and protect critical digital systems, such as industrial control systems, from cyber-attacks. While these devices are commonly used in high-security environments, for example, defense, where they assist as connections between two or more networks with varying security classifications, the technology is also being used to impose one-way communications outbound from critical digital systems to unauthorised networks connected to the Internet.
Unidirectional Network Market Overview
A unidirectional network, also known as a unidirectional gateway or data diode, is a network appliance or device that only allows data to flow in one direction. Data diodes are most commonly found in high-security environments, such as defense, where they connect two or more networks with different security classifications. With the rise of industrial IoT and digitization, this technology is now used at the industrial control level for facilities such as nuclear power plants, power generation, and safety-critical systems such as railway networks.
