What SeaNet Co. does
SeaNet Co., Ltd. (씨넷) is a privately-held South Korean marine electronics company founded in 2008 and headquartered in Busan. It develops and supplies integrated navigation, communication, satellite, and cybersecurity systems for commercial vessels, offshore platforms, and defense/specialized maritime applications, operating through four business divisions — Maritime Business, Marine Offshore Business, Cyber Security (under the SEACURE brand), and Special Business — and maintaining sub-brands SEES (smart ship), SEACURE (cybersecurity), and SEATALK (communication). Its product portfolio spans gyro compasses (SGY-1000), marine radars (SR-120), voyage data recorders (SV-100), electronic inclinometers (SEI-108), magnetic compasses, weather fax, fixed piloting units, explosion-proof cameras, GMDSS, satellite communications, UHF systems, IP PBX, citadel communication, and a high-throughput radar interface box (RIB-10) with the SRx visualization platform. Core technology sits in certified hardware engineering, inertial navigation (covered by a registered patent), and a software / network integration stack that links bridge navigation, ship communications, and onboard IT/OT cybersecurity.
The company sells primarily via direct B2B engagement with Korean and international shipyards (newbuild fit-out) and shipowners (retrofit and operating-vessel support), priced exclusively through inquiry-based quotation with no public price list and no third-party distribution channel. It generates revenue through project-based hardware sales (navigation, communication, network integration) and accompanying professional services for cybersecurity implementation, consulting, audits, and monitoring of SEACURE for both newbuild and operating vessels. Notable named customers include the major Korean shipbuilders — Hanwha Ocean, Samsung Heavy Industries, Hyundai Heavy Industries, Hyundai MIPO Dockyard, DSME — and shipowners HMM, Solvang, and Hapag-Lloyd. The company is led by CEO Ryu Yun-ki (류윤기) and operates from multiple Busan-area sites plus Pangyo and Ulsan offices. Its competitive position is anchored by a wide set of international maritime certifications (MED Module B and D, IECEx, ATEX, KC, KG Type Approval, RINA Approval in Principle, plus ISO 9001/14001/45001/27001) and is reinforced by participation in the Korea Maritime and Fisheries Institute's K-SeaQ joint export brand, first showcased in Indonesia in 2025.
