What Cydome does

Cydome is a UK-headquartered maritime cybersecurity company founded in 2018 that builds an AI-powered platform, Cydome Protect, providing real-time protection, vulnerability scanning, and risk management across IT, OT, and communication systems aboard vessels and offshore facilities. The platform is class-certified (ClassNK Innovation Endorsement) and ISO 27001/27017 certified, with maritime-specific AI trained on domain data and features spanning asset inventory, network intrusion detection, endpoint protection, OT-specific monitoring (including ECDIS isolation breach detection), GPS/GNSS spoofing detection, and pre-built compliance automation for IACS UR E26/E27, IMO 2021, NIS2, NIST CSF 2.0, and USCG requirements. Adjacent offerings include a 24/7 managed SOC, AI-powered maritime threat intelligence, penetration testing, newbuild certification services, crew cyber awareness training, and Cydome Embedded for offshore energy assets.

Cydome sells primarily through direct enterprise field sales to shipping companies, shipowners, and offshore operators, supplemented by channel partnerships with the dominant maritime connectivity vendors — Inmarsat, Speedcast, MarPoint, and Navarino — on whose appliances Cydome Protect can be deployed. The revenue model combines subscription-based platform licensing, recurring managed SOC services, subscription threat intelligence and per-seat training, and project-based professional services. The company serves a diversified customer base across commercial shipping (TMS Cardiff Gas, Newport S.A., ASM Shipping, Laskaridis), offshore (Danchor Offshore), ports (Ashdod), and oil and gas tanker operators, with recent expansion into offshore wind energy and a growing international footprint through offices in Greece, Germany, Japan, the United States, and Singapore, plus strategic platform partnerships with Rakuten Maritime and ABB announced in 2026.
