SSenStone, a Korean certification security company, has secured a total investment of 6 billion KRW (approximately 4.5 million USD) from firms including KDB, ES Investor, and Daeduck Asset Management. With this investment, SSenStone aims to establish a strong foothold in the global operational technology (OT) security market. KDB’s continued follow-up investments reflect their confidence in SSenStone’s technology and growth potential. In this process, a global security company, rather than a domestic competitor, was used as a peer group for comparison. The company commented, “This demonstrates the investment industry’s consensus that SSenStone is a promising company with strong global market competitiveness.”

SSenStone’s one-way dynamic authentication technology, OTAC (One-Time Authentication Code), has already been successfully deployed by Toss Bank, Kakao Bank, and Hana Card. Furthermore, by securing contracts with domestic financial institutions and companies to provide an authentication solution that can prevent 70% of non-face-to-face financial fraud—amounting to over 500 billion KRW (around 375 million USD) annually—the company has established a stable customer base while tapping into significant market potential.

SSenStone is also accelerating its expansion into international markets. OTAC technology has been successfully implemented in Indonesia’s electronic revenue stamp service, and SSenStone is leading advancements in OT/PLC system security in collaboration with global PLC manufacturers. The company has completed both Proof of Concept (PoC) and Minimum Viable Product (MVP) development with two of the world’s top five PLC manufacturers, including LS Electric, and is now in the production phase with one of them. Commercialization efforts for PLC devices equipped with OTAC technology are currently underway.

In particular, SSenStone’s PLC certification technology has already been registered and validated in the marketplace of Phoenix Contact, a prominent German PLC manufacturer. SSenStone has recently expanded its business into areas with similar security challenges, such as remote terminal units (RTUs), distributed control systems (DCS), supervisory control and data acquisition (SCADA) systems, and human-machine interfaces (HMIs). The company aims to position itself as a leader in the OT security market.

SSenStone CEO Yoo Chang-hoon stated, “This investment reaffirms the technological capabilities and growth potential of SSenStone, which is setting itself apart as a unique Korean security company. It serves as a crucial stepping stone for us to become a leading player in the global OT security market. We will continue to lead globally by securing an irreplaceable position for OTAC technology across various industries through ongoing technological innovation and business development.”
