Waterfall Security Solutions' Unidirectional Security Gateway is a combination of hardware and software designed to protect operational technology (OT) and industrial control system (ICS) networks. The gateway provides unbreachable protection for OT environments while allowing secure and continuous access to OT data. It uses hardware-enforced technology to assure safe and reliable operations, with software-enabled connectivity for interoperability and ease of use. The integrated hardware and software protect operations in real-time by gathering data from a source network and pushing it through one-way hardware, which can only transfer information in one direction. The software on the destination network then makes the data available for business automation, monitoring, and other functions. The gateway enables safe IT/OT integration by allowing an OT network to connect securely to a less secure IT network. It defeats online cyber attacks, reduces downtime and equipment damage, and ensures operational continuity. The Unidirectional Security Gateway provides network segmentation and effectively creates an 'air gap' that cannot be breached by remote attacks, offering stronger protection than traditional firewalls.
