Company Overview#
SSenStone develops authentication technology for users, devices, IoT, PLC, and OT/ICS environments. Its core technology is OTAC, a one-time dynamic authentication code.
The company addresses a common security issue: fixed passwords and static credentials are hard to protect across many devices and industrial systems. OTAC replaces static values with changing codes that can be verified without the same one-time code being reused.
Technology & Product#
OTAC is SSenStone’s core one-way dynamic authentication technology. It supports authentication between people, devices, and control systems.
Endpoint OTAC applies the technology to ICS and OT environments. It helps restrict PLC access to approved users and devices, and supports security work linked to NIS2, CRA, NERC CIP, and IEC 62443.
Other product areas include TAP OTAC for card-tap authentication, IoT Auth Platform OTAC, and HomeNet OTAC.
Market & Use Cases#
SSenStone is relevant for industrial sites, OT operators, IoT device makers, financial institutions, access-control systems, and smart-home environments.
Use cases include PLC access control, device authentication, phishing-resistant authentication, industrial remote access, and dynamic credential replacement for connected devices.
Traction & References#
SSenStone has more than 340 global patent applications, more than 200 registered global patents, and more than 380 global IP assets, based on its official About page.
The company was ranked first in the Baby Unicorn program under Korea’s K-Unicorn project in 2020. It also won the 2020 Europas Award in the cybersecurity category and the Cyber Security Breakthrough Award for Authentication Solution of the Year.
Global business is connected through swIDch, and swIDch states that OTAC technology has been provided to more than 50 customers.
Collaboration Relevance#
SSenStone can work with industrial operators, PLC makers, OT security teams, IoT device companies, banks, and access-control providers. A useful PoC can test dynamic authentication for PLC access, device registration, or remote industrial maintenance.
For Korea-Europe collaboration, SSenStone is relevant to OT security, NIS2, CRA, IEC 62443, and industrial cyber-resilience programs.
