Trusted by the world's leading shipbuilders — HD Hyundai, Samsung Heavy Industries, and Hanwha Ocean — Cooyangi is the definitive cyber-resilience platform built for the maritime industry.
The Rising Tempest – 2026 Maritime Cyber Threat Landscape
The maritime sector is under unprecedented digital siege. Ransomware attacks on commercial vessels surged to 42 incidents in 2025 — an 18% year-over-year rise — according to the CYTUR 2026 Maritime Cyber Threat white paper. As vessels grow smarter, their attack surface grows wider.
2022
28 ransomware incidents — early warning signs emerge.
2023
32 incidents — port infrastructure targeted.
2024
36 incidents — OT systems increasingly compromised.
2025
42 incidents (+18% YoY) — record high, $1.3B in losses.
2026
Threat surface expanding with autonomous vessels.
Shockwave Statistics
The financial and operational toll of maritime cyber threats is accelerating. These numbers represent more than data — they signal an industry-wide crisis demanding immediate action.

Introducing Cooyangi – The Maritime Cyber Shield
Cooyangi delivers one unified platform built on five pillars — Identify, Protect, Detect, Respond, and Recover — securing both IT and OT environments across every class of vessel, from LNG FSRUs to fully autonomous cargo ships. One platform. Complete coverage. Zero compromise.
Proven Trust – HD Hyundai's Global Cyber-Resilience Certification
The Milestone
In June 2024, HD Hyundai became the first Korean shipbuilder to earn Approval in Principle (AiP) from all six major classification societies — LR, ClassNK, KR, BV, DNV, and ABS — for its ship-cyber technology.
Cooyangi at the Core
The "Hi-Secure" suite powering HD Hyundai's new vessels runs on Cooyangi's core engine, delivering real-time threat analytics fleet-wide. With IACS mandating cyber-resilience for all contracts signed after July 2024, HD Hyundai proved compliance ahead of schedule.
60% Reduction
In mean time to detect (MTTD) cyber events during the 2025 pilot fleet
6 Societies
Simultaneous AiP certifications — an industry first for a Korean builder
Proven Trust – Hanwha Ocean's ABS-Approved OT Solution
ABS Approval in Principle
In June 2025, ABS granted Approval in Principle to Hanwha Ocean's OT cybersecurity solution for FPSO units — developed in partnership with SIGA Data Security. The solution integrates directly with Cooyangi's threat-intelligence engine, extending ship-wide visibility to offshore processing assets.
"Receiving ABS AIP validates our commitment to operational resilience. Cooyangi's AI-driven analytics are the backbone of our real-time defense."

Samsung Heavy Industries – Digital Shipbuilding & Cooyangi
Smart Ship 2030
In 2025, Samsung Heavy Industries selected Cooyangi as the standard cyber-resilience layer for its next-generation smart ship platform, directly aligned with its landmark "Smart Ship 2030" initiative.
A joint R&D program is now underway to co-develop a container-level intrusion-prevention module that encrypts cargo-data streams end-to-end — currently being trialed across three 2026-class container vessels.
How Cooyangi Works – The 5-P Framework
Cooyangi's architecture maps directly to the NIST Cybersecurity Framework, purpose-engineered for the unique demands of maritime IT and OT environments.
Identify
Asset inventory and network topology mapping for every on-board system — IT, OT, and SCADA.
Protect
Zone-based segmentation, automated patch management, and AI-driven vulnerability hardening.
Detect
Signature and behavior-based detection of ransomware, GPS spoofing, and DDoS attacks in real time.
Respond
One-click isolation, remote forensic capture, and coordinated crew alerts — aligned with ABS incident-response playbooks.
Recover
Automated rollback of compromised containers, secure firmware re-flashing, and continuous post-incident analytics.
