SEOUL, South Korea – 02 June, 2026 – SSenStone announced that it has secured a strategic investment from Hyundai Motor Group through a Hyundai Motor Group affiliate investment partnership. The investment was made through a third-party allotment capital increase.
The investment comes as operational technology (OT) endpoint security is receiving growing attention alongside the expansion of smart manufacturing, software-defined factory (SDF) initiatives and remote maintenance environments.
SSenStone has been advancing technologies designed to identify and authenticate users attempting to access OT endpoints while maintaining operational continuity in existing industrial environments.
Its One-Time Authentication Code (OTAC) technology enables unidirectional dynamic authentication without static password-based credentials or continuous network connectivity, making it suitable for isolated industrial environments. Based on this technology, SSenStone is expanding its OT authentication and user access control business through OTAC Trusted Access Gateway (TAG), designed for OT endpoints including PLCs, HMIs, RTUs, DCSs and SCADA systems, and to strengthen user authentication and access control without requiring replacement of legacy equipment, OEM support or modification of existing configurations.
SSenStone previously secured a field validation reference in the critical infrastructure sector through a project with Korea Water Resources Corporation (K-water) related to authentication systems for water facility monitoring and control equipment. The company also supplied OTAC Trusted Access Gateway (TAG) to a global energy solutions company for use in a live production environment.
In addition, SSenStone is continuing proof-of-concept projects and product development discussions with global industrial automation companies, including LS ELECTRIC in Korea. Together with its London-based global headquarters swIDch, SSenStone continues to expand collaboration in the OT endpoint authentication and access control sector.
“This investment represents more than simple funding,” said Yoo Chang-hoon, CEO of SSenStone and swIDch. “It is a very meaningful milestone that a company operating real global manufacturing environments recognised the importance of OT endpoint security and authentication-based access control, and highly evaluated the potential of SSenStone’s technology.”
“As AI-based automation and manufacturing digital transformation continue to accelerate, the importance of identification, authentication and access control for endpoint equipment — the final point of contact in OT environments — will continue to grow,” he added. “SSenStone will continue advancing technologies and expanding global collaboration to enable practical preventive security without disrupting existing OT environments.”
