Waterfall Security Solutions

What the company sells

Waterfall Security Solutions offers software-enabled hardware platforms. Waterfall Security Solutions says critical infrastructure operators face the challenge of getting data where it is needed without compromising the security of the industrial environment.

Waterfall Security Solutions sells a remote access product named HERA, short for Hardware-Enforced Remote Access. HERA provides the functionality of remote access. Hardware Enforced Remote Access enables remote management, updates, and troubleshooting for OT networks. Waterfall for IDS enables industrial intrusion detection systems to be deployed and integrated with enterprise-based and cloud-based Security Operations Centers. Unidirectional Gateways provide enterprise and out-sourced Security Operations Centers with access to vital network data. Unidirectional Cloud Gateways gather data from industrial and OT sources, convert the data into cloud-friendly protocols, and push the data through unidirectional hardware out to the Internet and to vendor and proprietary cloud systems. Vendors use Unidirectional Remote Screen View and Secure Bypass when they need to adjust manufacturing equipment remotely.

The Waterfall WF-500 DIN Rail is a Unidirectional Security Gateway in a compact design for space-constrained sites. Waterfall Security Solutions offers the smaller form factor for substations, pumping stations, compressor stations and other places where space is limited. Unidirectional Gateways replicate historians, databases, OPC servers and more to business networks. Unidirectional Gateways safely replicate OPC servers, historians and other vendor systems for use by vendor cloud services.

Waterfall Security Solutions protects OT systems for electric power generation, including conventional generation, nuclear generation, power transmission, power distribution, and control centers. Waterfall's unidirectional solutions enable safe ICCP and IEC 61850 MMS connectivity to third-party partners. Unidirectional Gateways forward DNP3, IEC 60870-104, IEC 61850 and other status and fault information to SCADA systems and engineering teams. Waterfall's unidirectional technology provides secure connectivity and remote access for the Oil & Gas industry throughout the supply chain, including upstream, midstream, and downstream. Unidirectional Gateways provide protection for drilling, ballast control, sub-sea operations and other aspects of offshore platforms, with high availability options available when platform policies dictate.

Waterfall's unidirectional technology protects the OT of water utilities against IT related network threats. Unidirectional Gateways provide real-time data to regulators and other third parties about emissions, treatment systems, quality sampling and other systems. Unidirectional Gateways are used for the replication of data from the mining operations' OT network to its IT network and The Cloud. Waterfall's Unidirectional technology is used to secure industrial controls for railways such as the signaling system, as well as rail operation control centers. Unidirectional Gateways replicate SQL Server and other databases of locomotive locations out to enterprise networks and cloud servers. Waterfall's unidirectional technology protects the pharmaceutical, food & beverage, automobile, aircraft and other manufacturing industries. Unidirectional Gateways replicate OEE servers and information to cloud-based systems.

Unidirectional Gateways replicate OPC servers, real-time databases, Syslog alerts, SNMP alerts and other critical performance indicators to enterprise systems and users, and external vendors and service providers. Waterfall Unidirectional Gateway hardware prevents any data exfiltration or leakage from the high security network back to the low security sources.^{[1][4][5][6][7][8][9][10][11][12][13]}
