NEW YORK – October 22, 2014 – Waterfall Security Solutions announced today that it is providing a new layer of security across its family of market-leading, stronger-than-firewall Unidirectional Security Gateway and FLIP product lines. 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, industrial and next-gen firewalls only offer marginal protection from hackers and insider threats, as they leave networks vulnerable to sabotage and data exfiltration. Waterfall Security’s Unidirectional Security Gateway technology offers stronger industrial perimeter security. Building on this more secure approach, 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.

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.
