Waterfall Security Solutions Offers Better than Firewall Protection



Israel’s Waterfall Security Solutions, provider of strong network security products which protect the safety and the reliability of control system networks, is providing a new layer of security across its self-declared stronger-than-firewall Unidirectional Security Gateway and FLIP product lines.

The company declares its mission to be to eliminate the use of firewalls in critical infrastructure control systems. The company develops products which its boasts provide stronger-than-firewall protections for industrial control networks. Waterfall’s products are deployed in utilities and critical national infrastructures throughout North America, Europe, Asia and the Middle-East.

Application Data Control manages application layer data by applying rules, policies and verification tests to application flowing between information technology (IT) business networks and operational technology (OT) industrial networks. Application Data Control addresses the risks of both data exfiltration attacks and targeted, cybersabotage attacks against industrial networks.

Industrial cloud services require integration between IT and OT networks, and many organizations turn to firewalls to facilitate this need. However, as Waterfall points out, industrial and next-gen firewalls only offer marginal protection from hackers and insider threats, as they leave networks vulnerable to sabotage and data exfiltration. The company boasts that its Security’s Unidirectional Security Gateway technology offers stronger industrial perimeter security.

Building on this more secure approach, it says, Application Data Control adds a layer of sophisticated, policy-based controls to more securely process industrial application data; to control which data points, types, files, tags, fields and values are allowed to leave OT networks; and to ensure that information entering OT networks complies with safety and security policies.

Waterfall points out that NERC CIP, IEC 62443-3-3, NRC 5.71 and other local and international regulations and guidelines are embracing and endorsing Unidirectional Security Gateways as a stronger alternative to firewalls.

“Application Data Control represents a dramatic leap forward in the practice of cybersecurity for control system network perimeters to meet the needs of industrial sites and critical infrastructures, ” said Lior Frenkel, CEO and co-founder of Waterfall Security. “This solution facilitates safe, secure and reliable integration of IT, OT and external networks to maximize operations’ efficiency and enable advanced remote services.”

Application Data Control is an option available for all Waterfall Security product lines, and can be applied to even difficult proprietary and undocumented communications with industrial historians and applications; industrial protocols; relational databases; messaging middleware; file transfer mechanisms; and many other industrial and IT protocols and applications.
