Its flagship product, CylusOne, is designed for the diversity and complexity of rail and metro environments and protects signalling, control, communications, trackside and onboard systems. CylusOne uses machine learning to speed detection of malware and artificial intelligence to determine behaviour and handle responses. The system is compatible with CBTC and ETCS and is intended for both mainline and urban networks to maximize performance, capacity and availability. Cylus entered a commercial partnership with Alstom, which invested US$7 million for a minority stake and will take one board seat; the technology is slated for initial implementation on the Tel Aviv metropolitan light rail system serving about 200,000 passengers a day. The partnership aims to integrate cybersecurity into rail processes and solutions globally and to help drive cyber-resilience standards for mobility.

Cylus develops a platform that enables rail companies to detect cyber-attacks in their operational networks, including signaling systems and rolling stock, and to block attackers before they can cause damage. Key platform features include enhanced security that preserves existing safety mechanisms, centralized operational visibility through a unique interface that makes trackside and trainborne devices visible to operators, multi-vendor integrated systems protection to identify weak links, and preemptive threat response. The company targets railways and metros and is led by CEO Amir Levintal, formerly director of the IDF Cyber R&D Division; Boaz Zafrir serves as president and is a former CEO of Israel Railways. Cylus was founded in 2017 by veterans of the Israeli Defense Forces' Intelligence Corps' technological intelligence and security units. As of January 2018 the company raised $4.7M in seed funding from investors including Zohar Zisapel, Magma Venture Partners, Vertex Ventures and the SBI Group. The platform's focus on safety-integrated cybersecurity and multi-vendor support positions it to serve operators seeking centralized visibility and proactive defense.
