Waterfall Security Solutions and OPSWAT Develop Security Solution for Critical Infrastructure

Waterfall Security Solutions’ Unidirectional Security Gateways and data diodes are widely used in the industrial control networks and critical infrastructures. OPSWAT is known for its multiscanning solutions designed to deliver anti-malware protection with increased detection rates and minimized performance overhead. The two companies came together in a technological partnership to create a joint solution for protecting unidirectionally protected nuclear generation networks and other critical industrial infrastructures.


A unidirectional network refers to network appliance or device allowing data to travel only in one direction. The technology is leveraged to guarantee information security in high security environments such as defense, nuclear power plants and electric power generation.

The unidirectional security gateways or data diodes help establish connections between two or more networks of varying security classifications to allow data to pass from one side -- the “low” side -- of a network connection to another -- the “high” side -- and not the other way around. The technology enables the high side network to receive data from the low side while maintaining the confidentiality of data on the high side. The system helps protect the sensitive data from the intrusions from the Internet.

Waterfall and OPSWAT will lend their technologies to create a solution that combines Waterfall’s hardware-enforced Unidirectional Security capabilities and OPSWAT's Metascan server technology.

In the joint solution, Waterfall's Unidirectional Gateways will perform a data scan using OPSWAT's Metascan engine before the data is transferred through the gateway system. The joint solution can be used to ensure that data entering critical networks or corporate networks is free of malware.

Waterfall’s hardware-enforced Unidirectional Security Gateways safely and securely integrate industrial networks with corporate networks

The partnership makes it possible for the Unidirectional Security Gateways to be used to securely transfer new antivirus signatures into network-isolated OPSWAT Metascan servers. Metascan is often used at nuclear generators and other critical infrastructure sites, where network connection is not available for automatic antivirus engine updating. These facilities use Metascan to scan files entering or leaving critical networks, particularly on USB sticks and other removable media.

Waterfall Security Solutions recently introduced a secure network integration solution for OSIsoft PI Asset Framework (PI AF). With this new version of the Waterfall PI connector, Waterfall Security Solutions replicates the PI Asset Framework from safety-critical and reliability-critical networks to corporate networks, creating new possibilities for secure integration.
