Insert Role

Waterfall Security Solutions, the OTsecurity company, and Cylus, theglobal leader in rail cybersecurity, announced a partnership providing a joint security solution for rail signaling and rolling stock systems, ensuring that safety-critical rail network infrastructure is inaccessible to hackers. The optimised security solution integrates Waterfall’s Unidirectional Security Gateways with the CylusOne™ continuous monitoring solution, eliminating operational network blind spots without adding risk to railway system operations.

Waterfall’s reliable, ruggedized gateways replace firewalls in industrial network environments. By ensuring unidirectional data flows from operational technology(OT) to information technology (IT) networks, Unidirectional Gateways guarantee control networks’ highest Safety IntegrityLevel, blocking attacks originating in external networks. Integrated with Cylus’ vendor-agnostic rail cybersecurity solution, the joint offering allows rail operators to continuously monitor safety-critical networks, providing visibility ,threat detection and response as well as a secure flow of information through Waterfall’s security hardware.

“Today’s rail systems are becoming increasingly connected and automated in order to improve business efficiencies and passenger experience – but this also increases cyber risk,” said Amir Levintal, CEO and co-founder of Cylus. “Our partnership withWaterfall offers additional solutions to rail customers, combining the deep, real-time visibility into OT networks already provided by CylusOne with the most robust, hardware-based physical protections for safe, continuous and efficient operations.”

“The rail systems industry is very safety focused, and cybersecurity is vital to safety,” adds Lior Frenkel, CEO and Co-Founder ofWaterfall Security Solutions. “Our partnership with Cylus gives rail system operators a powerful tool to assure safe, secure and reliable operations.”

CylusOne is the first cybersecurity solution designed specifically for rail and metro environments. Utilising deep packet inspection, CylusOne monitors the data flow within specific safety-critical rail network protocols. The joint solution allows rail operators to safely and reliably eliminate blind spots, reveal asset connections, uncover safety requirement breaches, and diagnose impending service availability issues, all while reducing exposure to external cyber-attacks. Together, Waterfall and Cylus deliver safe IT/OT integration with deep, enterprise-wide IT and OT network monitoring and intrusion detection to protect rail equipment and service availability.
