With the mandatory implementation of the International Association of Classification Societies (IACS) Unified Requirements for ships’ cyber resilience (UR E26 and E27), the certification burden on the shipbuilding and shipping industries has surged, and a domestic technology that automates security processes based on design data is drawing attention as a market solution. Previously, manual execution of risk assessments and supporting documentation required for ship certification took several months, but the introduction of technology that proactively blocks threats and automates documentation is being evaluated as an alternative to resolve a major challenge for the industry.

CYTUR (CEO Cho Yong-hyun), a company specializing in maritime and ship cyber security, announced that it has completed a Series A funding round worth KRW 5.2 billion, recognizing its advanced technological capabilities. This financing is a follow-up investment after a Pre-A round in 2024, with Sunbo Angel Partners, STIC Ventures, and Johns & Rocket participating. The investors are reported to have positively evaluated the completeness of CYTUR’s “ship life-cycle tailored security technology” and its global contract performance in the commercial shipping sector amid the trend toward mandatory cyber security in the shipbuilding and shipping markets.

CYTUR’s core competitiveness lies in its ability to manage cyber risks throughout the entire process (full life cycle) from ship design and construction to operation. Its proprietary “ship cyber threat modeling” technology identifies security vulnerabilities in advance through virtual simulation and supports regulatory compliance documentation. It has enhanced efficiency by converting complex certification procedures that used to take several months into an automated system based on design data. This technology has been officially recognized for its technical capabilities and commercialization potential, and was designated as a “2026 Excellent Information Security Technology Product” by the Ministry of Science and ICT and the Korea Internet & Security Agency (KISA).

These technological capabilities are translating into tangible results in the global market. CYTUR has demonstrated strengthened response capabilities to enhanced international regulations by securing cyber security contracts for dozens of commercial vessels in collaboration with global shipping companies such as Rakuten Maritime. In addition, it was invited to the “Maritime Cyber Security Summit” held in Florida, United States, where it presented its proprietary security solutions to global stakeholders including the U.S. Coast Guard (USCG), attracting attention from the global market.

CYTUR plans to focus the newly raised capital on expanding its workforce in maritime defense cyber security and advancing its solutions. Going forward, the company intends to provide vulnerability management and supply chain security services tailored to warship-specific environments, where various systems such as radar and combat systems are integrated, and to accelerate its entry into overseas shipbuilding and offshore markets in countries such as the United States and Japan.

CEO Cho Yong-hyun of CYTUR stated, “This government technology designation and our order performance in the global market indicate that CYTUR has entered a market expansion phase,” adding, “Based on our proven technological capabilities in the commercial vessel sector, we will target the naval MRO (maintenance, repair, and overhaul) market and expand overseas to solidify our position as a global maritime cyber security company.”
