About Cylus
Cylus provides cybersecurity for railway operators. It sells a platform that monitors, detects and protects rail operational technology across infrastructure, rolling stock, control centres and stations. The company serves passenger rail, urban transit, freight rail and infrastructure managers. Its aim is to keep services available and safe while helping operators meet regulations and standards. The main product is CylusOne. It builds asset inventories by passively observing OT communications, using deep packet inspection and fingerprinting without scanning or probing systems. It maps relationships between assets and keeps inventories current as networks change. It also identifies vulnerabilities, detects threats and operational anomalies in real time, and supports compliance reporting. Detection is tailored to rail protocols and message semantics, which reduces false positives. Response is designed to avoid disrupting safety-critical systems such as positive train control.
