[Tech Startup Story] SSenStone: Building a Global Cybersecurity Startup

Changhoon Yoo, CEO of SSenStone, shares the company’s dynamic growth story—how its outstanding security technology and scalability earned global recognition and led SSenStone to become a five-time winner of major international startup competitions.

SSenStone is an authentication security startup that has made waves in the cybersecurity industry, sweeping domestic and international startup support programs and competitions with its superior technology.

At the core of SSenStone’s innovation is OTAC (One-Time Authentication Code) technology, an authentication method that identifies users through dynamically generated codes created directly on the client device. By adopting a one-way authentication approach that operates without server or network connections, SSenStone completely blocks hacker intrusion during the authentication process. As a result, OTAC is widely regarded as one of the most secure authentication methods available today.

Backed by more than 120 global patents, SSenStone has developed a wide range of business models. In Asia, the company has secured commercial success across industries ranging from digital payments in Indonesia to IoT-based smart grid solutions. In Europe, SSenStone has received business proposals from global banks, automotive companies, and defense-related organizations.
