Problem
Railway operational technology (OT) faces increasing cyber threats, potentially compromising safety, disrupting operations, and causing significant financial losses. Existing security solutions often lack the deep understanding of rail-specific protocols and systems needed to effectively detect and mitigate these threats. This leaves critical infrastructure vulnerable to sophisticated attacks targeting signaling systems, rolling stock, and trackside equipment.
Solution
Cylus provides CylusOne, a cybersecurity platform specifically designed to protect railway OT environments from cyber threats. CylusOne offers continuous monitoring and real-time threat detection through deep packet inspection (DPI) of rail-specific protocols like ERTMS, CBTC, and PTC. The platform provides comprehensive asset visibility across the entire rail ecosystem, from trains to tracks, enabling proactive identification and mitigation of vulnerabilities. CylusOne integrates with existing Operations Control Center (OCC) and Security Operations Center (SOC) systems, offering remediation playbooks and virtual segmentation to ensure compliance with rail cybersecurity standards.
Target Audience
Cylus targets railway companies, infrastructure managers, and rail operators responsible for ensuring the safety, security, and operational integrity of their rail networks.
